I am using EF code-first and I have put a custom attribute on some of the fields in a model, which I want to exclude(like, I dont want to send the Id attribute value to client side).
Now, I need to return only the columns which doesn't have the attribute.
Right now, I am thinking to do it in 2 steps: Get all the data then filter by the attribute.
But I know, this can be done in a single query.
Please help.

My Question is not belonging to how to use two models on same razor view ! basically I have a user table in which i have fields like(userid,name,email,password,gender,country,department,IsActive) and my form is working fine i am able to insert update and delete i have not use EF , what i did i create the table in sql server and create the model in my model folder , in my view i have put the required field validator for all these columns and they are mandatory to input while inserting or updating.
Now I want to have another view with another controller where i do not want to show all 8 fields instead want to show just these four columns( username,email,gender,IsActive)
when i am using the same model for the other controller and view then it loads the record correctly on index view ,but when i update the required it fires validation error as all my fields are mark as required so it ask to input the rest of four fields value as well.
I have tried to remove these un-necessary fields from model in controller code before saving using Bind([Exclude]"""") but it did not work.
I have tried modelstate.remove("") this approach works fine for all fields but my password field is still throwing validation error . someone says you need to use viewmodel and in viewmodel you have to put both of your model like the full model and small model, I want to ask how my small model would be mapped to my user table (as table["tableName"] this cannot be applied to two models and pointing to same table without primary foriegn key relation .
Share example please i am confused
modelState.Remove("Password")
This remove all model values which are un-necessary but not removing the password field which gives error while updating the
You have required fields missing data or some fields are not null when being saved. What you are trying to do is completely ok. You are basically using a Virtual Model. This is what I do. In the "get", you fix your model and send it to the view. You work with it and then when you submit, you receive the model in the "post", but it is missing several REQUIRED fields. So what you need to do is, retrieve the same record from the database, update the 3 or 4 fields from the view model and then save that model that you retrieved with the new data. This is one way. (VM = view model)
1. send VM to view
2. add data in the view
3. submit
4. receive VM in POST Controller
5. get same record from DB
6. update the particular fields using the VM data
7. save the updated record to database. This is the record you retrieved in 5.
Another way is to have all the missing fields in the model but not showing them in the view. However you need to mention them in the view, otherwise they will not post. so you need to use
#Html.Hidefor( x=> x.NameOfField)
This will ensure that the field is sent back for posting. Any field with a [Required]... is required. You cannot miss it!
How will your small model be mapped to the Database. It will not. You will transfer the data from the small model to the model that is mapped in the database... with ALL the fields. Either you get the missing values from the database or from the view by using Hidefor.
example
dbmodel.Field1 = vm.field1;
dbmodel.Field2 = vm.field2;
dbmodel.Field3 = vm.field3;
I hope this helps
I am creating a new Joomla Component. I am able to create custom fields for the component backend forms - but I am not able to create Dynamic Custom Fields.
What I would like to do is have a field that is dynamical populated based on the value of a previous field. The easiest way to explain this is the simple country,state,city breakdown.
Field 1 = Country
Field 2 = State (Based on what the user selected as as Country in Field 1)
Field 3 = City (Based on what the user selected as State in Field 2)
The fields would of course need to be refreshed, reset as the user picks a different country etc.
The data to populate the fields would also all need to come from a database based on the previous fields value.
I am guessing this needs to be done via ajax or javascript or something? But wondering if there is an official way? Especially since there are database calls involved.
Please let me know if there is anything I can explain better..

I ended up just creating text fields but then validating the input to make sure the values added are correct.
im using marketo and the documentation says that you can Filter with custom fields
but this isnt working
i hope some of you know why or how ??
what i know do is
XXX.mktorest.com/rest/v1/leads.json?filterType=lastName&filterValues=testlastname
thanks in advance
The "lastName" field is part of the standard set of attributes for a lead in Marketo. Unfortunately, it is not one of the standard attributes that you can query the Get Multiple Leads REST API as a filterType.
The standard set of attributes to query the Get Multiple Leads REST API as a filterType are id, cookie, email, twitterId, facebookId, linkedInId, sfdcAccountId, sfdcContactId, sfdcLeadId, sfdcLeadOwnerId, and sfdcOpptyId.
You can query the Get Multiple Leads REST API for a custom field that you create in Marketo. A Marketo custom field is a field extends the standard set of lead attributes.
We have a requirement to pre-populate the Contact Form with user information on load if the user is a logged in user. So that, user need not fill his information using the webform.
Is there any way to do this using webforms for marketers?
Data is coming from a service api in json format. Need to figure out a way to bind it to fields either in server side or in client side.
Sitecore Version 7.1 140117 WFFM Version "Web Forms for Marketers
2.4.0 rev. 140117"
Have a look at Sitecore - Webforms For Marketers Form - Use ReadQueryString Option. Basically, there is a checkbox, ReadQueryString, in presentation details that gives you the option to fill in the default values from the query string. If checked, you use the item names of the fields (not the display name or title) as keys and the values you want to set the fields to as the values in key-value pair in the querystring.
Create a new rule based on use default value from user profile [fieldname] field and amend it to pick up the value from your service API.
This will be your best way and simplest option in my opinion.
I use this same approach prepopulating ucommerce data from its API.
Create custom field and then you can pre-populate values as per your need.
Like if you want to populate any value in Single line text field the create custom field for this and then reflect forms dll and copy code then update code as per your need.

My requirement is to create a custom data annotation attribute for my project. The requirement is to validate the min/ max length of a specific product from the database, which will be retrieved from the database using the ProductID. I have a dynamic page for each product where there are two fields called max length & min length. User inputs the values in these two fields which needs to be validated from the database. Product table contains all the products & one will be selected by passing a productId.
Please suggest some pointers to implement the above.
Thanks in advance.
This validation you can do only in the server side and not in client, so I see two options.
Remote Validation - You can use remote validation when you want to perform the validation and show the error message through ajax.
IValidatableObject - By implementing this interface in the class you can do both the validations at the same time and return all the validation error messages as a collection. By this way the validation will happen after the form is normally submitted.
