Allow withRelated functions to be executed for nested relations

Currently, if I specify that a relationship should be eager loaded on a fetch, it’s possible to specify an object within the “withRelated” list passed to the fetch options, and this can be used to modify the query used when loading a particular relation. However, this only works for single-level relationships.

This is a feature request, to make this work for multiple levels. One possible solution would be to allow specifying an array of functions, and pop the array and pass to the next level of the relation loading.

Eg.

model.fetch({
    withRelated: [
        {'relation1.subrelation': [null, (query) => { query.sortBy('id'); }]}
    ]
});

Which would not execute anything when loading “model.relation1”, but would execute the provided function when loading “relation1.subrelation”.

Actually if you look the implementation then this should work as well.

model.fetch({
    withRelated: [
        {'relation1':  () => { /*do nothing or something*/ }},
        {'relation1.subrelation': (query) => { query.sortBy('id'); }}
    ]
});

The project leadership of Bookshelf recently changed. In an effort to advance the project we close all issues older than one year.

If you think this issue needs to be re-evaluated please post a comment on why this is still important and we will re-open it.

We also started an open discussion about the future of Bookshelf.js here https://github.com/bookshelf/bookshelf/issues/1600. Feel free to drop by and give us your opinion. Let’s make Bookshelf great again
