About the $singles fetch, shouldn't it behave the same as any other fetch?

About the renaming, by default restmod does a underscore -> camelcase name conversion on decode and a camelcase -> underscore conversion on encode. Renaming can be disabled using the disableRenaming() builder method. What kind of issues are you having?

I missed the after-save hook when I reviewed the code earlier today, some feedback:

if(!model){
   collection.push(this.$encode()); // should use encode
} else {
    // i think it would be better to just replace the cached object since $encode returns the complete object state.
    angular.extend(model, this.$encode()); 
}

@iobaixas - Singles should behave the same yes and no. For instance:

   var model = $restmod.model("/api/zoo") 
   model.$search()  //->  [ {  id: 1, type: 'panda' }, .... ]

but if I do:

   model.$find(1) //-> { id: 1, type: 'panda' } 

I would think that it would pull the panda object out of the previous search collection so that you dont have multiple references.

Now the $single that you mentioned above, should response just the same I agree.

@iobaixas - Is there a way to disableRenaming at a global / provider level?

Ups, didn't see that last question, about that, I just realised that the README is missing provider usage directions, you can set a base model in the config stage like this:

module.config(function($restmodProvider) {
  $restmodProvider.pushModelBase(function() { // Dont really like the name for this method, any thoughs?
    this.disableRenaming():
  });
});

About the new implementation, I will miss the local storage support... Why aren't you caching single $fetch results?

To return results from $search when doing a $find with an id $search returned you could do something like

this.on('after-fetch-many', function(xhr){
  cache[this.$url()] = this;
  angular.forEach(this, function(record) {
    cache[record.$url()] = record;
  });
});

@kenborge - Ya I thought about something like that. Managing the list(s) and singles together gets tricky.
