The shape of the data was essentially the same. No shuffling was applied, so the row order never changes.

Therefore all that was needed was:

The error message is telling you that you can't deserialize to a &'static str. As the deserializer goes along creating the entries, the &str keys could only have as long a lifetime as a borrow of the buffer the deserializer is reading the file into. But &'static str must point to a str which lives forever.

I see two solutions here: The easy way and the hard way.

The easy way: Just change &'static str in the type to String and it compiles. This way the HashMap owns the keys; serde already knows how to deserialize owned strings.

The issue seems to be the line

If you want to be a purist about MVC design, then game logic would go in the controller, not the view or the model. Their roles should be:

• model: The current state of the game; e.g. which characters are in which game board array slots. It knows nothing about the view or the controller.
• view: The visual representation of the game board. It reads from the model, but doesn't necessarily hold a reference to it.
• controller: The game logic. It responds to user actions by updating the model and telling the view to redraw itself based on the model. It has strong references to the view and the model.

That said, if your game logic is fairly simple, then separating things out into a model, view, and controller may be overkill. Most of the time, I start with a view controller class file and a corresponding view controller in a storyboard. If it gets too complex, then I create a view and/or model. The view controller has an outlet to the view, the view has outlets to its subviews, and the view's controls are connected to IBActions in the view controller.

What's important is to look at this from the perspective of the class that depends on IFooModel That's probably the first place where you want to prevent coupling.

You can accomplish that by injecting the factory into the class that needs it, like this:

When your component renders it tries to get value from job.location.name but location is undefined before ajax request is completed. So I guess error is kind of Cannot read property 'name' of undefined.

To fix this you can define computed property locationName and return, for example, empty string when there is no loaded job object yet:
