问题 If I have a class similar to this: public class Person { public string firstName { get; set; } public string lastName { get; set; } public Pet myPet { get; set; } } When I create a custom model binder, the Post from my form will not be sending in a Pet, it would send in data like this: firstName: "myFirstName" lastName: "myLastName" myPet: "myPetsName" Since the Pet's name is passed in, and not the actual Pet object, the Pet object needs to be retrieved from within the model binder.

由 喜你入骨 提交于 2019-12-06 05:33:12
问题 I'm having trouble with default model binding naming convention when there is a child property.

What, exactly, does a modelbinder do? How to use it effectively?

MVC Web API Binding Model to a Derived Class

由 时间秒杀一切 提交于 2019-12-06 03:56:53
I am looking at how to bind a model to a derived class within MVC Web API, the issue I have is that I think I have found about 5 ways of doing it... What I have is: Models -> ModelBase ModelA : ModelBase ModelB : ModelBase Controller then containers the method: Post(ModelBase model) {} The data that is posted will be ModelA or ModelB, I want to add information to the HTTP Request metadata (think Content-Type: application/json; type=ModelA) and based on this tell MVC to bind the posted content to either A or B. In code I imagine something like: Bind(request, bindingContext) { // check request

ASP.NET MVC Updating a list of objects on one form? (model binding to a list)

由 久未见 提交于 2019-12-06 03:22:09
Quick question regarding updating a list of items in asp.net mvc. Basically I have an edit action method that returns a collection of objects (incidentally, the table structure of which looks as follows 'testID, assetID, Result' - a link table). I basically want this items to be displayed one after another in a form and to be able to edit them. The form should post back and the modelbinder do its magic. But, its not that easy. I have scoured the net and it seems the majority of the information about this stuff seems to be a little out of date. I've come across this post , which has not been
