Template-driven ngModel forms blog companion code
This is awesome, but I can't use this anywhere as there's no license specified - it would be great if you could specify how we can use/modify this example. In my opinion, WTFPL makes the most sense here, but that depends on your preferences.
In validate.ts:
return asyncValidator(control).map(v => {
const secondary = synchronousValid();
if (secondary || v) { // compose async and sync validator results
return Object.assign({}, secondary, v);
}
});
asyncValidator(control)
is not an array
My validator looks like this:
...
@Directive({
selector: "[selector-name][ngModel]",
providers: [
{
provide: NG_ASYNC_VALIDATORS, useExisting: SelectorClass, multi: true
}
]
})
export class SelectorClass implements Validator {
...
This approach/wiring does not appear to work for reactive forms. When using validators in FormBuilder.group({})
, the validators are not registered with the @Optional() @Inject(NG_VALIDATORS) validators: Array<any>
in component constructor. Interestingly enough, it does make the form invalid when the validation fails, but it's not showing me the "failures" messages.
Is this by design? Any pointers you could give me to get it to work both ways? Love what you've done here. Nice work. ๐
