batman.js 0.14.0 changelog

APP

Added: App.shouldAllowEvent.[event]. Callbacks in this hash will be called whenever the corresponding data-event is fired from anywhere within the app. Return false to prevent app-level propagation. For example:

class MyApp extends Batman.App
  @shouldAllowEvent.click = (event) ->
    return false

Fix: Prevent additional history items from being created if the users navigates to the page they are already on.
Fix: Nested resource routing names.
Deprecated: App loader utilities: App.controller, App.model, App.view, App.require. Batman does not care how you load your code, as long as it's loaded before calling App.run.

Added: Substantially better for support for polymorphic associations.
Added: Configure custom URL's for associations. Typically used for resources whose backends aren't quite as RESTful as they should be.
Added: A server response of 422 will result in the response being parsed as an error and the response's data being used injected into errors.
Added: A server response of 409 will result in a RecordExistsError.
Added: NumericValidator can now compare for equality.
Added: Batman.Model._mapIdentities to map many items and then add them to the set all at once.
Performance: Batman.Model.loadWithOptions uses mapIdentities instead of mapIdentity.
Change: Model instance methods are no longer bound to themselves. If you're passing model methods as callbacks make sure you bind them manually!
Fix: Respect sorted order in SetSort::find.
Fix: Respect sorted order of SetSort::merge.

Change: Moved the Batman.ViewStore's fetchFromRemote and prefix properties to Batman.config and rename them to fetchRemoteViews and viewPrefix.
Fix: Batman.DOM.setStyleProperty will respect !important in all browsers.
Fix: Don't intercept middle-click events.

Change: Rename Binding to ValueBinding.
Fix: Biding to the correct option when loading a <select> element. If the data is null when the binding is created, we bind to an option with an empty string.
Fix: Parsing keypaths that begin with numbers.
Added: The ability for bindings within subviews to update their values that have been added to the context via data-bind.
Deprecated: data-confirm event attribute.

Fix: The prepend and append filters don't prepend/append undefined to the string if the value is undefined. data-bind="undefinedValue | append 'my string'" now returns my string and not undefinedmy string.

Change: Promise accessors return the result of their promise function, such that promises which return valueA and asynchronously deliver valueB retune the delivered valueB instead of the returned valueA.
Change: Class promise accessors are now be recalculated after calling clear, e.g. Product.clear().
Added: Batman.Object::_resetPromise.

Added: A deprecation mechanism. Putting Batman.developer.deprecated inside a function will log a warning in the console in development mode.
Fix: Some cases where clearImmediate would break IE.
Fix: IE7 inability to access a character from a string using the index [] notation.
Fix: Support all symbols with unescapeHTML. e100aca
Fix: Bug in reduce where the reduction function returning undefined caused undesirable return values.
Fix: Bug when using arrays of models as the keys of a Batman.Hash.
Fix: Ensure that add is only called once when multiple items are added to a SetSort at the same time.
