how add rake task in devise in registration.erb file to match text filed value

Question

How to match license key with rake task and throw error if the key is wrong when signing up.

#sign up form    
<%= form_for(resource, as: resource_name, url: registration_path(resource_name)) do |f| %>
      <%= devise_error_messages! %>

      <div class="field">
        <%= f.label :email %><br />
        <%= f.text_field :email, required: true  %>
      </div>

        <div class="field">
          <%= f.label :username %><br />
          <%= f.text_field :username %>
        </div>

        <div class="field">
          <%= f.label :licensekey %><br />
        </div>

        <div class="field">
          <%= f.label :contactno %><br />
          <%= f.text_field :contactno %>
        </div>

        <div class="field">
        <%= f.label :password %>
        <% if @minimum_password_length %>
        <em>(<%= @minimum_password_length %> characters minimum)</em>
        <% end %><br />
          <%= f.password_field :password, maxlength:14, required: true, pattern:'[a-zA-Z0-9]' %>
      </div>

      <div class="field">
        <%= f.label :password_confirmation %><br />
        <%= f.password_field :password_confirmation, autocomplete: "off" %>
      </div>

      <div class="actions">
        <%= f.submit "Sign up" %>
      </div>
    <% end %>

    <%= render "devise/shared/links" %>

Here is the Rake task Im trying to define

require 'rake'
task :new => :environment do
   dump_key = "P1000FFSEJZHGRDUR1CSU73A"
end

I don't see a rake task necessary, check my answer below, I added an option if you still wanna run rake task in controller anyways. — svelandiag, Feb 01 '17 at 17:07

Look you don't need to create a rake task for this.

I will suppose that licensekey is an user attribute you already defined correctly with Devise.

Then you can override Devise registration_controller.rb and perform a validation.

#registration_controller.rb
class RegistrationsController < Devise::RegistrationsController
  def create
        #HERE YOU CAN PERFORM YOUR VALIDATION
  end
end

However I would recommend perform the validation at a model level instead of controller level, also run Rake tasks within a controller is not a good practice. If you are not sure how to override the devise create action check this thread.

update

In case you still want to run your validation from a rake task, then you can run rake task within the create action of your devise controller with: %x[rake name_task] replace name_task with the name of your task.
