Nested includes

[FernandoYu]

Hi, I've been trying to make a query with nested includes that looks like this:

// https://example.com/api/contacts?include=conversations.messages
const response = await contactSet.includeCollection(r => r.conversations.messages).findAll();

But I'm getting this error:

Property 'messages' does not exist on type 'PropertyInfoProxyRoot<EntityCollection<Conversation>>'

Is there any way that I can get that query?

After investigating a bit more, I found this solution:

const response = await contactSet.includeCollection(r => r.conversations)
            .thenIncludeCollection(r => r.messages)
            .findAll();

Which generates the following request:

https://example.com/api/contacts?include=conversations,conversations.messages

It might be useful to explain this feature in the documentation

Hi FernandoYu, glad you found a solution! Agreed - this is worth mentioning in the docs. We have already a section about includes and it can be extended a bit. PR welcome. ;)
