Finish creating a controller action

Question

I am creating an application (the User has many groups) in which an existing user can send invitations to invite people to join the group. If sign_up url has an invitation token, I need to override the default controller action to create.

routes.rb

devise_for :users do match '/users/sign_out', :to => 'devise/sessions#destroy' match '/users/sign_up/:invitation_token', :to => 'registrations#create' 

registrations_controller.rb

 class RegistrationsController < Devise::RegistrationsController #after_filter :add_user_to_group def new super end def create if !params[:invitation_token].nil? token = params[:invitation_token] @invitation = Invitation.where "token" => token if !@invitation.nil ? build_resource if resource.save if resource.active_for_authentication? set_flash_message :notice, :signed_up if is_navigational_format? sign_up(resource_name, resource) respond_with resource, :location => after_sign_up_path_for(resource) else set_flash_message :notice, :"signed_up_but_#{resource.inactive_message}" if is_navigational_format? expire_session_data_after_sign_in! respond_with resource, :location => after_inactive_sign_up_path_for(resource) end else clean_up_passwords resource respond_with resource end else flash[:notice] = "Invalid Token. Cannot signup with this Link." end else super end end def after_sign_up_path_for(resource_or_scope) @user = current_user raise @user.inspect @invitation = Invitation.where "recipient_email" => @user.email if !@invitation.nil ? @user.update_attribute(:invitation_id, @invitation.id) @user_group = UserGroup.new @user_group.user_id = @user.id @userGroup.group_id = @invitation.group_id @userGroup.save! end after_sign_in_path_for(resource) end 

end

This redirects me to the sign_up path, but performs checks to load the page.

Answer 1

I should have done something like that. I ended up adding code to add a token to the user model and had a separate controller action for accepting prompts:

user.rb

 after_create :accept_invitation, if: :token private def accept_invitation # Or whatever you need to add the invitation token. permission = Permission.find_by_token(token) if permission permission.update_attributes!(user_id: id, accepted: true) UserMailer.admin_accepted_invitation_email(permission).deliver end end 

registrations_controller.rb

 class Users::RegistrationsController < Devise::RegistrationsController layout "home" def accept_invitation @invitation = Permission.find_by_token!(params[:token]) @user = User.new(token: @invitation.token) end end
