Overview

Use with form object that responds to ‘validate` method, e.g. use Reform or Virtus with ActiveModel::Validations

Open the console and try:

validator_params = { form_object: 'validations/signup_form_company_name',
                     resource_model: 'company',
                     resource_attr_name: 'name',
                     resource_attr_value: 'Efigence' }

One can use the engine with any ActiveModel::Model object with ActiveModel::Validations included. For performance, even if the model is clobbered with validations, only validations on the specified field one will be fired. Examples:

validator_params = { form_object: '',
                     resource_model: 'company',
                     resource_attr_name: 'name',
                     resource_attr_value: 'efigence' }

Validate (also conditionally) virtual or model attribute set inside some before validation callback:

validator_params = { form_object: '',
                     resource_model: 'company',
                     resource_attr_name: 'vat_number_with_prefix',
                     resource_attr_value: '',
                     ignore_resource_attr_value: 'true',
                     resource_instance_additional_params: {country: 'Poland',
                                                           vat_number: '0123456789'} }

validator_params = { form_object: '',
                     resource_model: 'company',
                     resource_attr_name: 'vat_number',
                     resource_attr_value: '',
                     ignore_resource_attr_value: 'true',
                     resource_instance_additional_params: {business_owner: true,
                                                           vat_number: ''} }

validator = AjaxValidator::Validator.new(validator_params) tested_company = validator.validate tested_company.errors.to_a

  • ‘resource_instance_additional_params` hash is passed as args to given active model instance,

to handle before validation callbacks’ dependencies, however, if form object is used, additional params - if specified - must be handled by form object instance itself, implementations may vary.

  • set ‘ignore_resource_attr_value` to ’true’ if attribute value is assembled inside before validation

callback

  • validating virtual attributes, custom validation methods and custom validators are all supported
