tbone.models.bound

• tbone.models.bound:

  • Extends tbone.models.base.
  • Instead of setting data via query, the data held is bound to the return value of a state function.
  • This state function can query values from other models as part of its calculation; whenever those other models are update, the state function is automatically re-run in order to recalculate.

• model.state: Override this with a function to generate this model’s data. This has similar utility to T(prop, fn).

• tbone.hasViewListener(model): Returns true if a View is listening either directly or indirectly (i.e. through other model dependencies) for changes to model. This is used internally by TBone to prevent loading ajax data for any models that are not needed as part of the UI currently.

set function: T(prop, fn)

Binds prop to the live result of fn

• prop: String. e.g. ‘name’ or ‘person.name.first’.
• fn: Function. The return value of this function will be set to prop. This function gets re-run any time its dependencies change.
