Way to consume relationships on the fly ?

[alberto-f]

Hello, thanks for the project. It is really nice structure and the middlewares are a really nice feature.

I was wondering if there is any way to continue consuming the responses

Example:

jsonApi.define('post', {
  title: '',
  content: '',
  comments: {
    jsonApi: 'hasMany',
    type: 'comments'
  }
})

const post = await jsonApi.find('post', '1'); // trigger get request
const comments = await post.comments.findAll();  // trigger get request

Check out the README section on the URL Builder.

This may work:

const comments = await post.all('comment').get();

I believe the deserialization step in Devour throws away the information that's needed for what you like to do @alberto-f . I could be mistaken though..

I would like to have this functionality too; and I already thought about it. There's one problem that's keeping me from implementing it though: (using the code from your example) post.comments.findAll() will reserve the word findAll for that function. That means this name cannot be used anymore as an attribute or a relationship (collectively called fields).

I see two solutions (with several downsides):

1. use an underscore prefix for functions. e.g.: await post.comments._findAll()
2. Change the deserialization so that we keep attributes and relationships separate; but add convenient delegates to for non-clashing names; like such:

const post = await jsonApi.find('post', '1');

post.attributes.title // => the attribute "title"
post.title // a delegate to the title attribute

post.relationships.comments // => a relationship-object with methods like get and delete
post.relationships.comments.included[0] // => a resource-object; an [included related resource](https://jsonapi.org/format/#fetching-includes)

post.comments // a delegate to an included resource (only available if it's included)

I doubt that my second solution will be popular with the users of this library though since it seems like this was a deliberate design decision that was made long ago.
