Installation

Usage

To use validatable decorators you must addd @validatable decorators to your Model or POJO class first. This decorators add 3 methods to the class. validate, validateOrReject and validateSync

This addon uses class-validator under the hood but more ember way.

I'll list all available decorators here when I have freetime but in the mean time you can the code.

import {
  validatable,
  min,
  max,
  contains,
  int,
  email,
  fqdn,
  date,
  length,
} from 'ember-validatable-decorators';
import { attr } from '@ember-data/model';
import Model from '@ember-data/model';

@validatable
export default class PostModel extends Model {
  @length(10, 20)
  @attr('string')
  title;

  @contains('hello')
  @attr('string')
  text;

  @int()
  @min(0)
  @max(10)
  @attr('number')
  rating;

  @email()
  @attr('string')
  email;

  @fqdn()
  @attr('string')
  site;

  @date()
  @attr('datetime')
  createDate;
}

To check if model or POJO valid or not just need to call one of these 3 methods like this:

import { action } from '@ember/object';
import Controller from '@ember/controller';

export default class ApplicationController extends Controller {
  @action
  validate() {
    this.model.validate();
  }
}

And this call populates errors field in the model or POJO. You check check and display errors like this:

{{concat 'isValidated:' this.model.isValidated}}

{{#if this.model.isValid}}
  <p>Valid</p>
{{else}}
  <p>Invalid</p>
{{/if}}

{{#each this.model.errors as |error|}}
  <div class='error'>
    {{error.message}}
  </div>
{{/each}}

<hr />

{{#each this.model.errors.rating as |error|}}
  <div class='error'>
    {{error.message}}
    <br />
  </div>
{{/each}}

<button type='button' {{on 'click' this.validate}}>
  Validate
</button>
