Creating documents in relations

[cie]

Hi! How about something like

band.members.create(name: "Fletch")

? It looks better than

Member.create band_id: band.id, name: "Fletch"

Would be great, agreed. See #8, band.members is not really an object manager, it's just an array (in the case of embedded models) or a function that performs the appropriate find (in the case of related models). I welcome any pull requests that would implement this feature...

Ok, thanks. I don't yet know if I'll implement it or not. But I think if somebody implements it, they should consider also other Mogoid methods besides create (like push, new, where, find, delete) to make it more POLA.

Taking a look at this, it looks feasible in some cases but not others.

For example we can do this when resolving a has_many because we have access to the classname:

      @[relation] = do(relation, selector, class_name) ->
        (mod_selector = {}, options = {}) ->
          # first consider any passed in selector options
          mod_selector = _.extend mod_selector, selector
          # e.g. where {user_id: @id}
          if global[class_name]
            models = global[class_name].where mod_selector, options
            return Relation.new class_name, models...

The Relation class could then have your create method as well as others. But this is more difficult to do from the @where method because we don't have access to the actual class name from this location, from what I'm able to tell.

I retract my previous statement. I'll have a pull request shortly.
