Accept terms of use rails

Question

What is the best way to add a check for accepting terms of use in a rails app?

I can\'t seem to get validates_acceptance_of working quite right. I added a b

Answer 1

In your model,

validates_acceptance_of :terms

If you're using attr_accessible in your model then make sure you also add,

attr_accessible :terms

In your view,

<%= form_for @user do |f| %>
  ...
  <%= f.check_box :terms %>
  ...
<% end %>

There is no need for an extra column in the users table unless you plan on denying access to users who have not accepted the terms of service, which won't exist since they can't complete registration in the first place.

Answer 2

This is a working Rails 4 solution:

Terms of service doesn't need to be a column in the database

Form

= f.check_box :terms_of_service

models/user.rb

validates :terms_of_service, acceptance: true

And most important, devise will sanitize your parameters and terms of service will be removed from the submitted params. So:

registrations_controller.rb

class RegistrationsController < Devise::RegistrationsController
  before_filter :configure_permitted_parameters

  def configure_permitted_parameters
    devise_parameter_sanitizer.for(:sign_up) do |u|
      u.permit(:full_name,
        :email, :password, :password_confirmation, :terms_of_service)
    end 
  end
end
