RuleForEach was designed to prevent creation of trivial validators for simple collection items, and it’s implementation didn’t cover all possible use cases.

Updated 2015-01-17: As pointed out by Leblanc Meneses in the comments Angular 1.3 now supports interpolation with form, ngForm and input directives. This means that using expressions to name your elements: <div ng-form=”namesForm_{{$index}}” ng-repeat=”name in names”> <input type=”text” name=”input_{{$index}}_0″></input> <!– … –> </div> will work as expected: $scope[‘namesForm_0’] $scope.namesForm_1 // Access nested form elements: $scope.namesForm_1.input_1_0 … Read more
Here is a sample. It’s a min value validator where you pass in a number to validate. import {Control} from ‘angular2/common’; export const minValueValidator = (min:number) => { return (control:Control) => { var num = +control.value; if(isNaN(num) || num < min){ return { minValue: {valid: false} }; } return null; }; }; More details can … Read more

Try this – you need to actually create a date object rather than parsing the string NOTE: This will test the string AS YOU POSTED IT. YYYY-MM-DDTHH:MN:SS.MSSZ It will fail on valid ISO8601 dates like Date: 2018-10-18 Combined date and time in UTC: 2018-10-18T08:04:30+00:00 (without the Z and TZ in 00:00) 2018-10-18T08:04:30Z 20181018T080430Z Week: 2018-W42 … Read more
The charset doesn’t matter. The allowed characters matters more. Check the CSS specification. Here’s a cite of relevance: In CSS, identifiers (including element names, classes, and IDs in selectors) can contain only the characters [a-zA-Z0-9] and ISO 10646 characters U+00A0 and higher, plus the hyphen (-) and the underscore (_); they cannot start with a … Read more
You can use: validate :any_present? def any_present? if %w(field1 field2 field3).all?{|attr| self[attr].blank?} errors.add :base, “Error message” end end EDIT: updated from original answer for Rails 3+ as per comment. But you have to provide field names manually. You could get all content columns of a model with Model.content_columns.map(&:name), but it will include created_at and updated_at … Read more
