Rails devise registration form when having STI

I dont know how to create a worker and a association. So i am able to link those together. I have a type colulm in user.

This is my form(http://localhost:3000/workers/sign_up):

<h2>Create Worker</h2>

    <%= form_for(resource, :as => resource_name, :url => registration_path(resource_name)) do |f| %>
      <%=开发者_开发技巧 devise_error_messages! %>

      <p><%= f.label :email %><br />
      <%= f.text_field :email %></p>

      <p><%= f.label :kodeord %><br />
      <%= f.password_field :password %></p>

      <p><%= f.label :bekraeft_kodeord %><br />
      <%= f.password_field :password_confirmation %></p>

      <p><%= f.submit "Create" %></p>
    <% end %>

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

This is my models:

Class Worker < User
devise :database_authenticatable, :registerable
end

Class Company < User
devise :database_authenticatable, :registerable
end

Class User < Appliaction::Base
devise :database_authenticatable, :registerable
end

I want to create a register form that create a User and a Worker. I have colums in Workers table as Name, Age and Adress that i want in the registration form.

Should it be a nested form and have should i create the association between worker and User table.

Ok found the answer, what you have to is add the routes for your subclasses, and then dirrect the users to the relevant routes, like such

devise_for :companies
devise_for :workers

And then you probably going to want generate the view for each of them

script/rails generate devise:views companies

If there are no major differences in your view you can just render the file from the user templates in your companies templates like so

render :file => 'users/registrations/new'

In your controllers and view you will still use the standard user_signed_in?

Hope it helps let me know if you find a better way

I think you're looking for Worker has_one User. I don't think you need to inherit your Worker class from User. If you want to create a User after creating a Worker, you can do so in a after_create callback.
