How to manually set an object state to clean (saved) using ember-data
ember-data, ember.js
Solution
Looking at ember-data the uncommitted state has a 'becameClean' event which consequently sets the record as loaded.saved.
This should do the trick
record.get('stateManager').send('becameClean');
Problem
Explanation: I'm using ember-data for a project of mine and I have a question that revolves around the possibility of dirtying an object and then setting its state to clean again on purpose - without commiting the changes. The scenario is this: Say I've fetched an object via `banana = App.Fruit.find('banana');` and it has a description of "Yellow fruit!". Using XHR long-polling (or WebSockets), I may receive an updated version of the object because of another user having changed the description to "A tasty yellow fruit!" at any given point in time after I fetched the original object. Then, what I would like to do is to update the object to reflect the newly received data. For this, I've tried different approaches: I've tried calling `App.Store.load(App.Fruit, new_data);`. First of all, this approach doesn't work and secondly, this is not really what I want. I could've made uncommitted changes to the object myself and in this case, it would be undesirable to just discard those (assuming the `load()` call would overwrite them). I've tried looping through the new data, calling `.set()` - like so: `banana.set('description', new_data.description);` - in order to update the object properties with the new data (where applicable = not dirty). This works but it leaves the object in a dirtied state. In order to make the object clean/updated again - and not have the adapter commit the changes! - I've taken a look at the states the object travels through. These are (at least): - Step 1: Initially, the object is in the `rootState.loaded.saved` state. - Step 2: Calling `.set()` on a property pushes it to the `rootState.loaded.updated.uncommitted` state. - Step 3: Calling `App.store.commit();` returns the object to the `rootState.loaded.saved` state. Therefore, I've tried to manually set the object state to `saved` after step 2 like so: `banana.get('stateManager').goToState('saved');`. However, this doesn't work. The next time the store commits for any other reason, this maneuver produces an inFlightDirtyReasons is undefined error. Question: My question is: how can I manually change the state of a dirtied object back to clean (saved) again?
