问题
I have a resource A that has a navigation property that points to resource B. The schema looks like this:
Resource A:
- ID
- B (this is a one-to-many navigation property)
Resource B:
- ID
- Property1
- Property2
Can I update values of resource B (i.e. update property1 and property2 of B) through the navigation link of A? In other words, can I say A.B[5].Property1 = x?
In the OData spec and examples, I only see descriptions of modifying which instance of B is associated with A (i.e. modifying /A(0)/$links/B), but not whether or not I can do a PUT/MERGE to /A(0)/B(2) and modify B itself.
回答1:
You should be able to send a PUT request to /A(0)/B(2) and modify properties of B.
