如何使用导航属性更新Web API OData实体？

Question

Entity1 has a collection of Entity2 as a navigation property. I can successfully get Entity1 from ODataController with expanded collection of Entity2. But when I try to update Entity1 using ODataController PUT or PATCH methods, I can do it only when a collection of Entity2 is null. Otherwise Delta is null.

public IHttpActionResult Put([FromODataUri] int key, Delta<ClienteleExportTemplate> delta)

What is interesting: when I use POST method of the same ODataController nested collection of Entity2 is filled with values and I can successfully save Entity1. So the problem is only in PUT and PATCH methods.

This is my modelBuilder config for this entities:

modelBuilder.EntitySet<Entity1>("Entity1OData");
modelBuilder.EntitySet<Entity2>("Entity2OData");

I send values to POST and PUT methods as an JSON array using $odataresourse module for angularJs.

Currently not support update entity relationship, As workaround, you can use the $ref to update the entity relationship. Please refer here for example:
