ODataQuery.navigateTo() method to fetch related entities/collections

jinqu-odata version

1.1.3

Current behavior

Only expansion is available

Proposed behavior

navigateTo() method (which is usually preseeded by byKey() method) should append a navigation entity/collection name to the request uri and return a query typed to the navigated entity type.

Expected code:

const query: IODataQuery<Address> = service.companies()
  .byKey(5)
  .navigateTo(c => c.address)
  .select("id", "text");

const query2: IODataQuery<Address> = service.companies()
  .byKey(5)
  .navigateTo(c => c.addresses)
  .where(a => a.text == 'nice')

Getting related entities on the server side using EF: here

PS. Already implemented in my repository.
PPS. Simple OData Client also supports chaining of calls like ByKey()-NavigateTo()-ByKey()-NavigateTo()-..., but it would require procecing QueryParts just in the loop, and if Ids are globally unique, we can always access related entities by key from the main EntitySet, so I didn't implement that.
