Rails devise simple form not saving all fields

Question

When I went to generate the devise views I wanted to modify the new registration page to capture more than just the email & password. My devise user model has fields like

Answer 1

Take a look at the Rails and Devise example application from the RailsApps project. I've also written a Rails Devise Tutorial that explains in detail how to add attributes to a Devise sign-up form.

You need to tell Devise that the additional attributes are "permitted parameters." Otherwise, the "strong parameters" security measure introduced in Rails 4.0 will simply drop the unpermitted parameters, creating a new user without setting the additional attributes.

There are three different ways to add permitted parameters in Devise:

• override the default Devise registrations controller
• add code to the Application controller
• add an initializer file

The third way is the simplest. Add a file to your application:

# config/initializers/devise_permitted_parameters.rb

module DevisePermittedParameters
  extend ActiveSupport::Concern

  included do
    before_filter :configure_permitted_parameters
  end

  protected

  def configure_permitted_parameters
    devise_parameter_sanitizer.for(:sign_up) << :first_name << :last_name << :phone << :addressL1 << :addressL2 << :city << :postalCode << :province
    devise_parameter_sanitizer.for(:account_update) << :first_name << :last_name << :phone << :addressL1 << :addressL2 << :city << :postalCode << :province
  end

end

DeviseController.send :include, DevisePermittedParameters

You can see that you pass the additional parameters to the devise_parameter_sanitizer method. These two lines tell Devise to accommodate additional attributes. If you want to add other attributes, or different attributes, modify these two statements.

The rest of the file implements a Rails concern. Concerns are modules that can be mixed into models and controllers to add shared code. Typically, these modules go in a app/controllers/concerns/ folder and are added to a controller with an include keyword. In this case, we use the Ruby send method to add our mixin to the DeviseController object, adding include DevisePermittedParameters to the DeviseController without actually editing the code.

After making these changes and trying the application, you should see the additional attributes in the user record. If it doesn't work, show us more of your code, including the user model and controller.
