I want to create a JSON object out of ruby object on view file like
:coffeescript
files = {}
- #filelist.each do |f|
= files[f[0]] = f[1]
console.log(files)
it gives me an "Unexpected logic" error
following is array declared in controller
#filelist = Array.new
#filelist.push(['ref','count'])
#filelist.push(['input1','count'])
#filelist.push(['input2','count'])
In your view you first have to convert ruby array to json (inside view):
var filelists = $.parseJSON(<%= #filelist.to_json %>);
Then create a json object in view:
var jsonObj = {};
$.each(filelists, function(obj,index){
jsonObj[obj[0]] = obj[1];
});

I am trying to convert the NSDictionary into Json using NSJsonSerialization.Serialize. But i am not getting expected output
Code in Xamarin.iOS
var dictionary = new NSDictionary(
new NSString("userName"), new NSString("450012"),
new NSString("password"), new NSString("Abc134"),
new NSString("companyId"), new NSString("CM1")
);
request.Body = NSJsonSerialization.Serialize(dictionary, 0, out error);
the problem is that value of dictionary variable is showing
{{password":Abc134,companyId:CM1,userName:450012}}
instead of
{password:Abc134,companyId:CM1,userName:450012}
it is adding one curly braces at the front and back
is there any way to generate proper json string for user input values
There's nothing wrong with your json. If you print it in the console you will see that the value being printed is the value you expect.
{"password":"Abc134","companyId":"CM1","userName":"450012"}
Give it a try with:
Console.WriteLine($"{json}");
If you really, really want to get rid of of that "extra" curly braces just convert the result into string.
var jsonString = json.ToString();
The above should do the work.
I would just suggest you changing your method to this:
var json2 = NSJsonSerialization.Serialize(dictionary, NSJsonWritingOptions.PrettyPrinted, out error);
Using the PrettyPrinted option.
Hope this helps.-
Yes, you can try to create a custom object to serialize. Create a simple plain object to hold the data you want.
User user = new User() {
UserName = "JohnDoe",
Password = "xxx",
CompanyId = 01
};
request.Body = NSJsonSerialization.Serialize(user, 0, out error);
Then serialize it and you will see the proper json well formed.
Is there a way I can reference a list containing data from my database (item_list = inventory.objects.order_by('name')) in my jquery AJAX call?
This is my code:
/models.py:
class phonebook(models.Model):
name = models.Charfield(max_length=200)
phone_number = models.CharField(max_length=100)
/views.py:
def phonebook_home(request):
global phonebook
phonebook = phonebook.objects.order_by('name')
def get_next_3_contacts(request):
returnedContacts = phonebook[contactIndex:contactIndex+3]
return HttpResponse(phonebook)
/main.js:
var = ajax_call {
type: 'GET'
url: DEFINED_URL
data: {
index: contactIndex
},
dataType: 'html'
success: function (returned, textStatus_ignored, jqXHR_ignored) {
var contactIndex = 0
function phonebook_list(name, phone_number) {
"<li>" + name + " : " + phone_number + "</li>"
}
for(var index=0; index < 3; index++) {
var name = phonebook[index].name
var phone_number = phonebook[index].phone_number
$("ul").append(phonebook_list(name, phone_number))
}
contactIndex += 3
}
The phonebook[index].name / .phone_number returns "undefined" on my page. I want to keep my js file separate from my template file as it will be easier for me to debug, but unfortunately, this problem has stumped me. I also inputted an alert to test out if any data was being returned from the data base, which only returns a string containing the names of the contacts with no spacing in between contact names. Ex: "JaredSarahJohn".
All help and any bit of advice is appreciated!
A couple of things need to be cleaned up in order for this solution to work:
Your idea that global phonebook will be available from within get_next_3_contacts() is incorrect. When you make the AJAX call that will ultimately invoke get_next_3_contacts() the variable phonebook is no longer available. It went out of scope when the call to phonebook_home() completed.
What's the solution? Change phonebook_home() to accept an offset and count parameters. Have it hit the database and return the requested quantities. This is called pagination and is something you should get familiar with!
def phonebook_home(request, offset, count):
phonebook = phonebook.objects.all()[offset:offset+count]
But how do we get those results down to your AJAX handler? You can't just "return" a list of objects to the HTTPResponse() function - it's looking for text to render, not Model objects.
import json
from django.http import JsonResponse
def phonebook_home(request, offset, count):
status = "OK"
return_data = ""
try:
phonebook = phonebook.objects.all()[offset:offset+count]
return_data = json.dumps(phonebook)
exception:
status = "UH OH"
return JsonResponse({'data': return_data, 'status': status)
I am running this script for getting all form fields of a indd file.
var _ALL_FIELDS = "";
var allFields = myDocument.formFields;
for(var i=0;i<allFields.length;i++){
var tf = allFields[i];
alert(tf.id);
alert(tf.label);
alert(tf.name);
alert(_ALL_FIELDS = _ALL_FIELDS +\",\"+ tf.name);
}
What i have done is, created a soap-java based client and calling the runscript method.
Now i am able to get these fields but how to send these fields back to the client i.e. how to write this in response and then at client side how to read it from response.
Code for calling runscript method is:-
Service inDesignService = new ServiceLocator();
ServicePortType inDesignServer = inDesignService.getService(new URL(parsedArgs.getHost()));
IntHolder errorNumber = new IntHolder(0);
StringHolder errorString = new StringHolder();
DataHolder results = new DataHolder();
inDesignServer.runScript(runScriptParams, errorNumber, errorString, results);
Also I have found in docs that runScript method returns RunScriptResponse but in my case it's returning void.
http://wwwimages.adobe.com/content/dam/Adobe/en/devnet/indesign/sdk/cs6/server/ids-solutions.pdf
It looks like you want to return an array of formField names. You could take advantage of the everyItem() collection interface method in your javascript:
var result = myDocument.formFields.everyItem().name;
result;
The javascript will return the last value in the called script, so just to make it completely obvious, the last line is just the value to be returned.
On the Java side, the runScript method is passing the results variable as the 4th parameter, and that's where you'll find your response. So, after your code snippet, you might have something like this:
List<String> formFieldNames = new ArrayList<String>();
if (results.value.getData() != null) {
Data[] resultsArray = (Data[]) results.value.getData();
for (int i = 0; i < resultsArray.length; i++) {
formFieldNames.add(resultsArray[i].getData().toString());
}
}
I want to pass to create a json output with a dictionary with multiple models, like this:
results = {}
results["game_info_db"] = db.gameInfo.objects.get(name='name')
results["dlc_list_db"] = db.gameAddon.objects.filter(game__name='name')
What i tried is serialize (serializers.serialize) all dicts entrys and after this i dumps (simplejson.dumps) all the dict... but it doesn't seems to be correct ...
any sugestion ?
You could pass in the values of the models and convert it to a list:
results = {}
results["game_info_db"] = list(db.gameInfo.objects.get(name='name').values())
results["dlc_list_db"] = list(db.gameAddon.objects.filter(game__name='name').values())
return HttpResponse(json.dumps(results), mimetype='application/javascript')
The data will appear as objects on the javascript side. Assuming you have a name column, you can access the attributes like the following:
$.getJSON("/ajax/", function(data) {
var dlcs = data.dlc_list_db;
for (i = 0; i < dlcs.length; i++) {
var dlc = dlcs[i];
alert(dlc.name);
}
});
I am using Linq2SQL and working with a legacy system. The system was built in .Net but without a datalayer so I am transcoding it so that it will have one. I have a linq query that looks like this...
var data = from p in db.tblPeoples
orderby p.strLastName,p.strFirstName
select new
{
guidPersonId = p.guidPersonId,
strFirstName = p.strFirstName,
strLastName = p.strLastName,
strRank = p.tblCodesRank.strDescription,
strPhone = p.strPhone,
strEmail = p.strEmail,
strOffice = p.tblOrganization.strAcronym,
RolesList = p.tblRoles
};
and when I check the signature of the var it is an IQueryable and I have no idea what that is. In my datalayer I have this returning as an IQueryable, but when I try to use the datalayer version and then do a .where on the returned dataset to search on it, I get errors that I Cannot convert lambda expresstion to type 'string' because it is not a delegate type.
What should I do about this? I am trying to create code reuse and use my datalayer version that is already written. the data layer version looks like this:
public static IQueryable RetrieveAllPeople()
{
var data = from p in db.tblPeoples
orderby p.strLastName, p.strFirstName
select new
{
guidPersonId = p.guidPersonId,
strFirstName = p.strFirstName,
strLastName = p.strLastName,
strRank = p.tblCodesRank.strDescription,
strPhone = p.strPhone,
strEmail = p.strEmail,
strOffice = p.tblOrganization.strAcronym,
RolesList = p.tblRoles
};
return data;
}
Your return type should be IQueryable<T>, which is not the same as IQueryable.
To do so, you need to create a class to fill in your select instead of using an anonymous one like you do.
