Rails 4 - checkbox agreement validation fails on create new user registration using devise

Question

I'm trying to include a "accept terms of service" checkbox (called agreement) on a form. The app is using Devise for the user management.

views/devise/registrations/new.html.erb has:

<%= f.check_box :agreement, class: 'form-control' %>

The application_controller.rb has:

  def configure_permitted_parameters
    devise_parameter_sanitizer.for(:sign_up) { |u| u.permit(:agreement, :phone, :first_name, :last_name, :domain, :email, :password, :password_confirmation) }
  end

Then in the user.rb controller, it has

# neither of the below worked
# validates :agreement, :acceptance => true
validates :agreement, acceptance: true

If I view the data in the development.log, it shows the agreement field coming through correctly with a value of 1, which is (according to the Rails docs, the expected value for the validation):

Parameters: {"utf8"=>"✓", "authenticity_token"=>"jFg6+ZDM1qldh020lv/FQHxlgZkby2dhUbejjXurr4w=", "user"=>{"first_name"=>"Joe", "last_name"=>"Smith", "phone"=>"2098993344", "domain"=>"google.com", "email"=>"test@example.com", "password"=>"[FILTERED]", "password_confirmation"=>"[FILTERED]", "agreement"=>"1"}, "commit"=>"Create User"} 

However, any time the form is submitted it shows an error message that "Agreement must be accepted", whether it's checked or not.

Any ideas on what this is caused by?

Answer 1

Try using this for your validation

validates :agreement, acceptance: { accept: true }

as per the Rails documentation

:accept - Specifies value that is considered accepted. The default value is a string “1”, which makes it easy to relate to an HTML checkbox. This should be set to true if you are validating a database column, since the attribute is typecast from “1” to true before validation.

I had same scenerio like you did. This is how I accomplished similar to what you trying to do:

On routes.rb:

devise_for :users, :controllers => {:registrations => "registrations"}

Create new controller --> RegistrationsController.rb

class RegistrationsController < Devise::RegistrationsController

  def create
      if params[:agree] && verify_recaptcha
        super
      else
        build_resource(sign_up_params)
        clean_up_passwords(resource)
        if params[:agree].nil? && !verify_recaptcha
          flash.now[:alert] = "You did not agree and missing captcha"
        elsif params[:agree].nil?
          flash.now[:alert] = "You did not agree"
        elsif !verify_recaptcha
          flash.now[:alert] = "captcha not correct"
        end
        flash.delete :recaptcha_error
        render :new
      end
  end

end

and put the code on application_controller.rb

before_filter :update_sanitized_params, if: :devise_controller?

#accept additional attribute for user table
  def update_sanitized_params
    devise_parameter_sanitizer.for(:sign_up) {|u| u.permit(...)}
    devise_parameter_sanitizer.for(:account_update) {|u| u.permit(..)}
  end
