Instance Method Details

#resource_form_for(namespace = nil, **options) ⇒ Object

Generates ‘resource_form` helper to display form with basic arguments, elements, errors and options. Generated method can work without arguments in most of cases: it takes object from `resource` method.

Use ‘namespace` to add additional path parts to form action:

# this one will use [:site, resource]
resource_form_for :site

#### Options

  • ‘back_url` - default back url. Can be string with code, or hash for `url_for`.

  • ‘resource_method` - method to take resource from.

  • ‘method` - name of generated method.
