redux-collections's Issues

Handle counter in parent map

The Problem

post = { 
  id:  1,
  countComments: 125
  comments: [/* post.comments.length == 15 */]
}

We want that countComments to increment/decrement on children collection add/remove

New signature

In reducer creators and action creators use object as last argument for extra options.
Something like this:

collection('comments', { 
  parent: { posts: 2 } 
  mixin: (state, action) => state
});

dispatch(collectionAppend(comments, 'comments', { parent: { posts: 2 } }))
