control the display of errors in list forms and edit forms.

Customize the display of errors in forms

In order to change the default behavior, you must override the action controller error in the appropriate form. The only parameter of this method will be the error object, which must be set to the property associated with the error in the component flexberry-error (default error).

import Ember from 'ember';
import DS from 'ember-data';

export default Ember.Controller.extend({
  actions: {
    error(error) {
      if (error instanceof DS.AdapterError) {
        error = new Error('При обработке запроса произошла ошибка.');
        this.set('error', error);
      }
    },
  },
});

The setting error in the adapter

In order to change the default behavior, you must override the method handleResponse in the adapter, in which you can create error converting the response from the server in a user-friendly message.

import DS from 'ember-data';
import SilentError from '../errors/silent-error';

export default DS.RESTAdapter.extend({
  handleResponse(status, headers, payload) {
    if (!this.isSuccess(status, headers, payload)) {
      if (this.analyzeErrorResponse(status, headers, payload)) {
        return new SilentError();
      } else {
        return new DS.AdapterError(payload.error);
      }
    }

    return this._super(...arguments);
  },
});
