Currently, the only way for a directive to export a validator is by providing a function. This makes it ackward to write validators that depend on directive inputs. In addition to supporting functions as validators, classes implementing the Validator interface are supported too.
- fixes wrapping for object literal keys called `template`.
- spacing in destructuring expressions.
- changes to keep trailing return types of functions closer to their
function declaration.
- better formatting of string literals.
Closes#4828
Example:
var login = new Control("someLogin");
c.setErrors({"notUnique": true});
expect(c.valid).toEqual(false);
expect(c.errors).toEqual({"notUnique": true});
c.updateValue("newLogin");
expect(c.valid).toEqual(true);
BREAKING CHANGE:
Before:
ControlGroup.errors and ControlArray.errors returned a reduced value of their children controls' errors.
After:
ControlGroup.errors and ControlArray.errors return the errors of the group and array.
And ControlGroup.controlsErrors and ControlArray.controlsErrors return the reduce value of their children controls' errors.
Closes#4917
Allow ControlGroups and ControlArrays to contain errors from their level, and
errors from their children. [Design Doc](https://docs.google.com/document/d/1EnJ3-_iFpVKFz1ifN1LkXSGQ7h3A72OQGry2g8eo7IA/edit?pli=1#heading=h.j53rt81eegm4)
BREAKING CHANGE: errors format has changed from validators. Now errors from
a control or an array's children are prefixed with 'controls' while errors
from the object itself are left at the root level.
Example:
Given a Control group as follows:
var group = new ControlGroup({
login: new Control("", required),
password: new Control("", required),
passwordConfirm: new Control("", required)
});
Before:
group.errors
{
login: {required: true},
password: {required: true},
passwordConfirm: {required: true},
}
After:
group.errors
{
controls: {
login: {required: true},
password: {required: true},
passwordConfirm: {required: true},
}
}
Closes#3605
BREAKING CHANGE:
- we don't mark an element as bound any more if it only contains text bindings
E.g. <div>{{hello}}</div>
This changes the indices when using `DebugElement.componentViewChildren` / `DebugElement.children`.
- `@Directive.compileChildren` was removed,
`ng-non-bindable` is now builtin and not a directive any more
- angular no more adds the `ng-binding` class to elements with bindings
- directives are now ordered as they are listed in the View.directives regarding change detection.
Previously they had an undefined order.
- the `Renderer` interface has new methods `createProtoView` and `registerComponentTemplate`. See `DomRenderer` for default implementations.
- reprojection with `ng-content` is now all or nothing per `ng-content` element
- angular2 transformer can't be used in tests that modify directive metadata.
Use `angular2/src/transform/inliner_for_test` transformer instead.
This change moves many APIs to the angular2/core export.
This change also automatically adds FORM_BINDINGS in
the application root injector.
BREAKING CHANGE:
Many dependencies that were previously exported from specific
APIs are now exported from angular2/core. Affected exports, which
should now be included from angular2/core include:
angular2/forms
angular2/di
angular2/directives
angular2/change_detection
angular2/bootstrap (except for dart users)
angular2/render
angular2/metadata
angular2/debug
angular2/pipes
