Create a CRUD example

I would definitely love to see this.

My question would be covered by this--I'm having trouble imagining how Create works.

var userStore = Marty.createStore({
...
  receiveUser: function(user) {
    this.state.users.push(user);
    this.stateChanged();
  },

  createUser: function(user) {
    return this.fetch({
      id: 'CREATE_USER',
      locally: function() {
        return this.state.users[id]; // We don't know id
      },
      remotely: function() {
        return userApi.createUser(user);
      }
    });
  }
...
});

If you don't know id, how can local ever know if the API returned a successful result?

Yes, this would be hugely helpful. The Todo example is outdated and intentionally avoids using a lot of the more important features of Marty (fetch API, promises, state sources, etc)

Just as an FYI there is a chat example (es6 version) which is bit more advanced

The problems I faced with a CRUD (most of apps I need to work with have them 😢) are:

• Creating an item (which does not have an id which might be created by db)
• Always query to the server for data on the grids (this is related with #111)
• Adding an item while you have a paginated and sorted grid (do you manage sorting clientside?). If you query to the server without caching it, this won't be a problem.

I haven't found a direct match against those items on the examples. Reading the issues alongside with examples helped me to find my own way to implement a CRUD, though.
