You did not post what variable children is, probably some class field, but you cannot compare Java Strings with ==. Java Strings must be compared with .equals:
...
if (type.equals(children)) {
...
Use a debugger next time, to see what's happening in your code.
Your request and controller RequestBody structure do not match.
You need to use List.
#PostMapping("/child")
public List<CustomerDTO> childDTO(#RequestBody List<CustomerDTO> cusList){ // here list needs to be used
if(cusList != null && !cusList.isEmpty()) {
CustomerDTO cus = cusList.get(0); // it will get first element from the list, if you want to process all the elements then you need to iterate the list
return calculationService.childDTO(cus.getAge(),cus.getGender(),cus.getOccupation(),cus.getType());
}
}
Now other logic will be as it or you may change it as per your requirement.

I found that using [fromapi] attribute I can pass one complex object.
when I try to pass list of complex objects it doesn't work.
in the client side I use breeze. server side is webapi.
How can I do this?
You can create one DTO which has property for your list of objects
public class CreateUserDto
{
public string Name {set;get;}
public List<RoleDto> Roles {set;get;}
public CreateUserDto()
{
this.Roles = new List<RoleDto>();
}
}
public class RoleDto
{
public int Id {set;get;}
public string Name {set;get;}
}
And you can use that as the argument of your Web api endpoint
public HttpResponseMesssage Save(CreateUserDto model)
{
//Check model.Roles now
// to do : Return a response
}
From client, you can send data like this.(Assuming you have jQuery library loaded to your page)
var data { Name : "TestName",Roles:[]}
data.Roles.push(new { Id:1,Name:"Admin"});
data.Roles.push(new { Id:2,Name:"Editor"});
$.post("YourEndpointHere",data,function(response){
// do something with response
});
Modelbinding will take care of converting the posted form data to an instance of CreateUserDto in your Save method. You can access model.Roles property to get the list of complex objects you wanted.
you can use Dictionary as below:
[HttpPost]
public IQueryable<Product> GetProducts(Dictionary<string, object> data)
{
var categoryId = Convert.ToInt32(data["categoryId"]);
var category = _context.Categories.Single(a => a.ID == categoryId);
var galleryId = Convert.ToInt32(data["galleryId"]);
var langId = Convert.ToInt32(data["langId"]);
var searchStr = data["str"];
return category.Products.Where(a => a.GalleryID == galleryId, a.LanguageID == langId, a.Description.Contains(searchStr))
}
I have this very weird problem that I cannot get my head around. Perhaps someone could point out what I am doing wrong.
Basically, I am just trying to search items using Linq to Sitecore.
So, my classes look like ( I am using glass too)
[SitecoreType(TemplateId = "{TEMPLATE_GIUD}")]
public class MyMappedClass : SharedFieldClass
{
[SitecoreField(FieldName = "mylist")]
public virtual IEnumerable<SharedFieldClass> MyMultilistField { get; set; }
[SitecoreField(FieldName = "field1")]
[IndexField("field1")]
public virtual MyKeyValue field1 { get; set; }
}
[SitecoreType]
public class MyKeyValue
{
public virtual Sitecore.Data.ID Id {get;set;}
public virtual string MyValue{get;set;}
}
So when I do the below query it works as it's supposed to.
var results = context.GetQueryable<SearchResultItem>()
.Where(c => ((string)c["field1"]) == "{GUID}").GetResults();
But, when I do the below it returns 0 result.
List<MyMappedClass> results = context.GetQueryable<MyMappedClass>()
.Where(c => c.field1.MyValue == "{GUID}").ToList();
I have read this link . And I have followed the 2nd process described here for Glass to work with Sitecore7 Search (the "SharedFieldClass" contains all the basic index fields).
This is a pretty obvious scenario and I'm sure lots of people have done it already and I am doing something silly here.
Thanks in advance.
/## EDIT ##/
Okay so I've done a bit more digging on this. Not sure if it's a bug in ContentSearch/Luncene.NET API or I am missing something BUT seems like what was posted here is probably not TRUE and if you have a complex field type ( which you will ) you can not query with a mapped class against Lucene. ( not sure if this is also the case for Solr). If you are doing search against simple type like string and int then it works like a charm.
SO here're my findings:
After enabling DEBUG and LOG on for contentsearch I found that if I query like this context.GetQueryable<MyMappedClass>().Where(c => c.field1.MyValue == "{GUID}") what it gets translated into is DEBUG Executing lucene query: field1.value:7e9ed2ae07194d83872f9836715eca8e and as there's no such thing in the index named "field1.value" the query doesn't return anything. The name of the index is actually just "field1". Is this a bug ??
However, query like this context.GetQueryable<SearchResultItem>() .Where(c => ((string)c["field1"]) == "{GUID}").GetResults(); works because it gets translated into "DEBUG Executing lucene query: +field1:7e9ed2ae07194d83872f9836715eca8e".
I also did write a method in my mapped class like below:
public string this[string key]
{
get
{
return key.ToLowerInvariant();
}
set { }
}
Which allowed me write the below query with my MyMappedClass.
results2 = context.GetQueryable<MyMappedClass>().Where(c => c["filed1"]== "{GUID}").ToList();
This returned expected result. BUT the values of the fields in MyMappedClass are not filled ( in fact they're all null except the core/shared values like templateid, url etc which are populated in the filled document). So the result list are pretty much useless. I could do a loop over all of them and manually get the values populated as I have the itemid. But imagine the cost for a large result set.
Lastly I did this:
<fieldType fieldTypeName="droplink" storageType="YES" indexType="TOKENIZED" vectorType="NO" boost="1f" type="System.String" settingType="Sitecore.ContentSearch.LuceneProvider.LuceneSearchFieldConfiguration, Sitecore.ContentSearch.LuceneProvider" />
So this returned populated "field1" with the itemid in lucene query using "IndexViewer2.0". BUT this fails for MyMappedClass too as the value of "field1" in the document is a System.string .. but it is mapped as "MyKeyValue" in MyMappedClass SO it throws the below exception
Exception: System.InvalidCastException
Message: Invalid cast from 'System.String' to 'MyLib.MyKeyValue'.
SO, the big question is:
How does one query using his/her mapped class using the cool ContentSearch API ?
I bit more further digging got me to a working solution. Posting it here just in case anyone runs into this issue.
This is how my "SharedFieldClass" looked like ( which was somewhat wrong )
public abstract class SharedFieldClass
{
[SitecoreId]
[IndexField("_id")]
[TypeConverter(typeof(IndexFieldIDValueConverter))]
public virtual ID Id { get; set; }
[SitecoreInfo(SitecoreInfoType.Language)]
[IndexField("_language")]
public virtual string Language { get; set; }
[SitecoreInfo(SitecoreInfoType.Version)]
public virtual int Version
{
get
{
return Uri == null ? 0 : Uri.Version.Number;
}
}
[TypeConverter(typeof(IndexFieldItemUriValueConverter))]
[XmlIgnore]
[IndexField("_uniqueid")]
public virtual ItemUri Uri { get; set; }
}
And there's a class in Glass that does the mapping. Which looks like below:
var sitecoreService = new SitecoreService("web");
foreach (var r in results)
{
sitecoreService.Map(r);
}
for me this class was failing to map because of this line:
[SitecoreId]
[IndexField("_id")]
[TypeConverter(typeof(IndexFieldIDValueConverter))]
public virtual ID Id { get; set; }
It was throwing a NULL exception at sitecoreService.Map(r); line
So I changed it to below:
[SitecoreId]
[IndexField("_group")]
[TypeConverter(typeof(IndexFieldIDValueConverter))]
public virtual ID Id { get; set; }
And it worked. I'm not sure when the index field for ItemId in sitecore changed from "_id" to "_group" or whether it was always like that. But it is "_group" in the SearchResultItem class. So I used it and mapping was successful.
So to Sum it all the solution looks like this:
The Mapped Class:
[SitecoreType(TemplateId = "{TEMPLATE_GIUD}")]
public class MyMappedClass : SharedFieldClass
{
[SitecoreField(FieldName = "mylist")]
public virtual IEnumerable<SharedFieldClass> MyMultilistField { get; set; }
[SitecoreField(FieldName = "field1")]
[IndexField("field1")]
public virtual MyKeyValue field1 { get; set; }
// Will be set with key and value for each field in the index document
public string this[string key]
{
get
{
return key.ToLowerInvariant();
}
set { }
}
}
[SitecoreType]
public class MyKeyValue
{
public virtual Sitecore.Data.ID Id {get;set;}
public virtual string MyValue{get;set;}
}
And the query is:
List<MyMappedClass> results = context.GetQueryable<MyMappedClass>()
.Where(c => c["field1"] == "{GUID}").ToList();
That's it.
/* edited */
OH!! Wait that's not it. This will still fail to cast the complex type "MyKeyValue" when the "field1" is populated with guid in the index document.
So to avoid this I had to write my custom converter as #Michael Edwards suggested.
I had to modify the class slightly to fit my needs ..
public class IndexFieldKeyValueModelConverter : TypeConverter
{
public override bool CanConvertFrom(ITypeDescriptorContext context, Type sourceType)
{
var config = Glass.Mapper.Context.Default.GetTypeConfiguration<SitecoreTypeConfiguration>(sourceType, true);
if (config != null && sourceType == typeof(MyLib.IKeyValue))
{
return true;
}
else
return base.CanConvertFrom(context, sourceType);
}
public override bool CanConvertTo(ITypeDescriptorContext context, Type destinationType)
{
if (destinationType == typeof(string))
return true;
else
return base.CanConvertTo(context, destinationType);
}
public override object ConvertFrom(ITypeDescriptorContext context, CultureInfo culture, object value)
{
var scContext = new SitecoreContext();
Guid x = Guid.Empty;
if(value is string)
{
x = new Guid((string)value);
}
var item = scContext.Database.GetItem(x.ToString());
if (item == null)
return null;
return scContext.CreateType(typeof(MyLib.IKeyValue), item, true, false, new Dictionary<string, object>());
}
public override object ConvertTo(ITypeDescriptorContext context, CultureInfo culture, object value, Type destinationType)
{
var config = Glass.Mapper.Context.Default.GetTypeConfiguration<SitecoreTypeConfiguration>(value.GetType(), true);
ID id = config.GetId(value);
return id.ToShortID().ToString().ToLowerInvariant();
}
}
Not sure if it were the expected behaviour or not .. but for some reason, in the convertfrom method the value of the "object value" parameter was short string id format. So for scContext.Database.GetItem to work I had to convert it to a proper GUID and then it started returning proper item rather than null.
AND then I wrote my query like this:
results = context.GetQueryable<MyMappedGlassClass>().Where(c => c["field1"] == field1value && c["field2"] == field2value && c["_template"] == templateId).Filter(selector => selector["_group"] != currentId).ToList();
Looks like a fair bit of work to get it to work. I guess using the LinqHelper.CreateQuery method is the easy way out .. but as Mr. Pope suggested here that this method is not be used as this is an internal method.
Not sure what's the balance here.
/* end edited */
Please see my question description section for explanation on why I had to do things this way.
Also, (I bias opinion ) is the trick described here may not be valid anymore (please see my question description's edit section for the reason behind).
Also, index field for itemid in the Glass Mapper tutorial here is I think wrong (unless otherwise proven).
Hope it helps someone saving/wasting time.
You could create a custom field mapper for lucene that would convert from the Guid in the index to a glass model. I hacked this out but I haven't tested it:
public class IndexFieldDateTimeValueConverter : TypeConverter
{
public Type RequestedType { get; set; }
public override bool CanConvertFrom(ITypeDescriptorContext context, Type sourceType)
{
var config = Glass.Mapper.Context.Default.GetTypeConfiguration<SitecoreTypeConfiguration>(sourceType, true);
if (config != null)
{
RequestedType = sourceType;
return true;
}
else
return base.CanConvertFrom(context, sourceType);
}
public override bool CanConvertTo(ITypeDescriptorContext context, Type destinationType)
{
if (destinationType == typeof(string))
return true;
else
return base.CanConvertTo(context, destinationType);
}
public override object ConvertFrom(ITypeDescriptorContext context, CultureInfo culture, object value)
{
var scContext = new SitecoreContext();
return scContext.CreateType(RequestedType, scContext.Database.GetItem(value.ToString()),true, false, new Dictionary<string, object>());
}
public override object ConvertTo(ITypeDescriptorContext context, CultureInfo culture, object value, Type destinationType)
{
var config = Glass.Mapper.Context.Default.GetTypeConfiguration<SitecoreTypeConfiguration>(value.GetType(), true);
ID id =config.GetId(value);
return id.ToShortID().ToString().ToLowerInvariant();
}
My concern is that the ConvertFrom method does not get passed the type requested so we have to store this as property on the class to pass it from the CanConvertFrom method to the ConvertFrom method. This makes this class not thread safe.
Add this to the indexFieldStorageValueFormatter section of the sitecore config.
The problem here is that SearchResultItem is not actually an Item, but does have the GetItem() method to get the Sitecore item. What you need to do is the following:
List<MyMappedClass> results = context.GetQueryable<SearchResultItem>()
.Select(sri => sri.GetItem())
.Where(i => i != null)
.Select(i => i.GlassCast<MyMappedClass>())
.Where(c => c.field1.MyValue == "{GUID}").ToList();
I haven't worked with Glass specifically, but if you change your parent class to SearchResultItem, does it begin working? If so, that would indicate an issue with the SharedFieldClass parent class.
I want to validate for a empty Id value in the url.
../Task/EditEmployee/afccb22a-7cfd-4be5-8f82-9bd353c13b16
I want that if the Id is empty
../Task/EditEmployee/
Than redirect the user to a certain page.
public ActionResult EditEmployee(Guid Id)
{
//Some code in here
}
It may not be the best solution but you can take id parameter as string and try to parse it like this:
public ActionResult EditEmployee(string id)
{
if(string.IsNullOrWhiteSpace(id))
{
// handle empty querystring
}
else
{
Guid guid;
if (Guid.TryParse(id, out guid))
{
//Some code in here
}
}
}
Or
You can also create a regex constraint on the route but that may be too complicated and hard to understand. Map this route before the default one.
routes.MapRoute(
"TastEditEmployee",
"Task/EditEmployee/{id}",
new { controller = "Task", action = "EditEmployee" },
new { id = #"^(\{{0,1}([0-9a-fA-F]){8}-([0-9a-fA-F]){4}-([0-9a-fA-F]){4}-([0-9a-fA-F]){4}-([0-9a-fA-F]){12}\}{0,1})$" }
);
Then you can use id parameter as Nullable Guid.
public ActionResult EditEmployee(Guid? id)
{
//do something
}
Since Guid is a struct, the value of Id will be Guid.Empty if it was omitted. You can check for that.
public ActionResult EditEmployee(Guid Id)
{
if (Id == Guid.Empty) throw new ArgumentException("Id not specified.");
}
I'm using SPMetal in order to generate entity classes for my sharepoint site and I'm not exactly sure what the best practice is to use when there are multiple content types for a single list. For instance I have a task list that contains 2 content types and I'm defining them via the config file for SPMetal. Here is my definition...
<List Member="Tasks" Name="Tasks">
<ContentType Class="LegalReview" Name="LegalReviewContent"/>
<ContentType Class="Approval" Name="ApprovalContent"/>
</List>
This seems to work pretty well in that the generated objects do inherit from WorkflowTask but the generated type for the data context is a List of WorkflowTask. So when I do a query I get back a WorkflowTask object instead of a LegalReview or Approval object. How do I make it return an object of the correct type?
[Microsoft.SharePoint.Linq.ListAttribute(Name="Tasks")]
public Microsoft.SharePoint.Linq.EntityList<WorkflowTask> Tasks {
get {
return this.GetList<WorkflowTask>("Tasks");
}
}
UPDATE
Thanks for getting back to me. I'm not sure how I recreate the type based on the SPListItem and would appreciate any feedback.
ContractManagementDataContext context = new ContractManagementDataContext(_url);
WorkflowTask task = context.Tasks.FirstOrDefault(t => t.Id ==5);
Approval a = new Approval(task.item);
public partial class Approval{
public Approval(SPListItem item){
//Set all properties here for workflowtask and approval type?
//Wouldn't there be issues since it isn't attached to the datacontext?
}
public String SomeProperty{
get{ //get from list item};
set{ //set to list item};
}
Linq2SharePoint will always return an object of the first common base ContentType for all the ContentTypes in the list. This is not only because a base type of some description must be used to combine the different ContentTypes in code but also it will then only map the fields that should definitely exist on all ContentTypes in the list. It is however possible to get access to the underlying SPListItem returned by L2SP and thus from that determine the ContentType and down cast the item.
As part of a custom repository layer that is generated from T4 templates we have a partial addition to the Item class generated by SPMetal which implements ICustomMapping to get the data not usually available on the L2SP entities. A simplified version is below which just gets the ContentType and ModifiedDate to show the methodology; though the full class we use also maps Modified By, Created Date/By, Attachments, Version, Path etc, the principle is the same for all.
public partial class Item : ICustomMapping
{
private SPListItem _SPListItem;
public SPListItem SPListItem
{
get { return _SPListItem; }
set { _SPListItem = value; }
}
public string ContentTypeId { get; internal set; }
public DateTime Modified { get; internal set; }
public virtual void MapFrom(object listItem)
{
SPListItem item = (SPListItem)listItem;
this.SPListItem = item;
this.ContentTypeId = item.ContentTypeId.ToString();
this.Modified = (DateTime)item["Modified"];
}
public virtual void MapTo(object listItem)
{
SPListItem item = (SPListItem)listItem;
item["Modified"] = this.Modified == DateTime.MinValue ? this.Modified = DateTime.Now : this.Modified;
}
public virtual void Resolve(RefreshMode mode, object originalListItem, object databaseObject)
{
SPListItem originalItem = (SPListItem)originalListItem;
SPListItem databaseItem = (SPListItem)databaseObject;
DateTime originalModifiedValue = (DateTime)originalItem["Modified"];
DateTime dbModifiedValue = (DateTime)databaseItem["Modified"];
string originalContentTypeIdValue = originalItem.ContentTypeId.ToString();
string dbContentTypeIdValue = databaseItem.ContentTypeId.ToString();
switch(mode)
{
case RefreshMode.OverwriteCurrentValues:
this.Modified = dbModifiedValue;
this.ContentTypeId = dbContentTypeIdValue;
break;
case RefreshMode.KeepCurrentValues:
databaseItem["Modified"] = this.Modified;
break;
case RefreshMode.KeepChanges:
if (this.Modified != originalModifiedValue)
{
databaseItem["Modified"] = this.Modified;
}
else if (this.Modified == originalModifiedValue && this.Modified != dbModifiedValue)
{
this.Modified = dbModifiedValue;
}
if (this.ContentTypeId != originalContentTypeIdValue)
{
throw new InvalidOperationException("You cannot change the ContentTypeId directly");
}
else if (this.ContentTypeId == originalContentTypeIdValue && this.ContentTypeId != dbContentTypeIdValue)
{
this.ContentTypeId = dbContentTypeIdValue;
}
break;
}
}
}
Once you have the ContentType and the underlying SPListItem available on your L2SP entity it is simply a matter of writing a method which returns an instance of the derived ContentType entity from a combination of the values of the base type and the extra data for the missing fields from the SPListItem.
UPDATE: I don't actually have an example converter class as we don't use the above mapping extension to Item in this way. However I could imagine something like this would work:
public static class EntityConverter
{
public static Approval ToApproval(WorkflowTask wft)
{
Approval a = new Approval();
a.SomePropertyOnWorkflowTask = wft.SomePropertyOnWorkflowTask;
a.SomePropertyOnApproval = wft.SPListItem["field-name"];
return a;
}
}
Or you could put a method on a partial instance of WorkflowTask to return an Approval object.
public partial class WorkflowTask
{
public Approval ToApproval()
{
Approval a = new Approval();
a.SomePropertyOnWorkflowTask = this.SomePropertyOnWorkflowTask;
a.SomePropertyOnApproval = this.SPListItem["field-name"];
return a;
}
public LegalReview ToLegalReview()
{
// Create and return LegalReview as for Approval
}
}
In either situation you would need to determine the method to call to get the derived type from the ContentTypeId property of the WorkflowTask. This is the sort of code I would normally want to generate in one form or another as it will be pretty repetitive but that is a bit off-topic.
I am using ASP.NET MVC 3 with Entity Framework 4 using POCOs and want to query a set and select some properties to put into my viewModel. I will sketch a simplified version of my situation:
Situation:
I have an entity BananaTree containing a collection of Banana
public class Banana
{
public int Id { get; set; }
public int Size { get; set; }
public TimeSpan Age { get; set }
public string Description { get; set; }
}
public class BananaTree
{
public int Id { get; set; }
public ICollection<Banana> Bananas { get; set; }
}
I also have a view model BananaListItemViewModel used in the view showing a list of bananas for a certain banana tree. This view is managed by the BananaTreeController
public class BananaListItemViewModel
{
public int Id { get; set; }
public TimeSpan Age { get; set }
}
I have a Details action on the controller like so:
public ActionResult Details(int bananaTreeId)
{
var viewModel = from bananaTree in bananaTreeRepository.BananaTrees
where bananaTree.Id == bananaTreeId
from banana in bananaTree.Bananas
select new BananaListItemViewModel
{
Id = banana.Id,
Age = banana.Age
};
return View(viewModel);
}
What I want to change
This works fine and now I only select the items from the database that I need for my view model. However, I want to take out some more logic from my controller and am trying to do this as much as possible.
I would like to have a function in my repository like so:
IQueryable<Banana> GetBananas(int bananaTreeId)
{
return (from bananaTree in BananaTrees
where bananaTree.Id == bananaTreeId
select bananaTree.Bananas).Single().AsQueryable();
}
and use it like so:
public ActionResult Details(int bananaTreeId)
{
var viewModel = from banana in bananaTreeRepository.GetBananas(bananaTreeId)
select new BananaListItemViewModel
{
Id = banana.Id,
Age = banana.Age
};
return View(viewModel);
}
Question
My question is, in this case, will the two queries be combined and go to the database in one go like in my first example or will this first get all the bananas from the tree completely out of the database and perform the second query on that list? I would prefer the first case. If not, could I rewrite the GetBananas query to get that behaviour (for example like the query below)?
IQueryable<Banana> GetBananas(int bananaTreeId)
{
return from bananaTree in BananaTrees
where bananaTree.Id == bananaTreeId
from banana in bananaTree.Bananas
select banana;
}
Thanks very much in advance.
In your specific case, it will be only one query, if the call to Single() doesn't lead to the query to be executed. Unfortunately, I couldn't find any info on whether it does or does not. The call to AsQueryable does not trigger the execution as long, as the Bananas property really is an IQueryable.
According to http://msdn.microsoft.com/en-us/library/bb156472.aspx, the call to Single doesn't execute your query.
Conclusion:
You code should result in only one query.
In general:
You can pass an IQueryable from one method to another without it being implicitly executed.
The following code will result in only one SQL statement executed at the end, when the call to ToList happens:
IQueryable<Banana> GetBananasByWeight(int weight)
{
return from banana in Bananas where banana.Weight = weight;
}
IQueryable<Banana> FilterByQuality(IQueryable<Banana> bananaQuery, int quality)
{
return bananaQuery.Where(b => b.Quality == quality);
}
public List<Banana> GetBananas(int weight, int quality)
{
var query = GetBananasByWeight(weight);
var filteredBananas = FilterByQuality(query, quality);
return filteredBananas.ToList();
}
