Solution

  • I am new to Loopback but the current (v3) documentation states:

    Warning: This is not yet implemented. You must currently validate in code; see Validating model data.

    For now you have to put your validation code in the model's JS file.

    This is the example given in the documentation:

    common/models/user.js

    module.exports = function(user) {
  user.validatesPresenceOf('name', 'email');
  user.validatesLengthOf('password', {min: 5, message: {min: 'Password is too short'}});
  user.validatesInclusionOf('gender', {in: ['male', 'female']});
  user.validatesExclusionOf('domain', {in: ['www', 'billing', 'admin']});
  user.validatesNumericalityOf('age', {int: true});
  user.validatesUniquenessOf('email', {message: 'email is not unique'});
};

    This is reminiscent of Angular's Reactive form validation.
