Рельсы с jquery с использованием обновления проблемы Ajax .Каменный блок

Question

У меня здесь приложение для рельсов с базовой формой. Моя цель - иметь форму, которая добавит нового пользователя в базу данных, а затем обновит блок .each с помощью jquery и ajax.

В настоящее время данные вводятся как раз в базу данных, но префикс приводит к ошибке nil, а не последней записи. Ясно, что переменная в какой-то момент теряет значение.

вот мой код:

/controllers/registrations_controller.rb

class RegistrationsController < Devise::RegistrationsController 
    skip_before_filter :require_no_authentication 
def create 
    @user = User.new(params[:user]) 

    respond_to do |format| 
     if @user.save 
     set_flash_message(:notice, :signed_up) 
     format.html { sign_in_and_redirect :user, @user} 
     format.js { render 'landing/create'} 
     else 
     format.html { render action: "new" } 
     format.json { render json: @user.errors, status: :unprocessable_entity } 
     end 
    end 
    end 
... 
end 

/landing/_sub_account_partial.html.erb

<li><%= current_sub_account %></li> 

/landing/create.js.erb

$("ul").prepend("<%= escape_javascript(render 'landing/sub_account_partial', :current_sub_account => @current_sub_account) %>"); 
    $('#user_email').val(''); 

/landing/signup_page_2.html.erb

<%= form_tag(user_registration_path, :remote => true) do %> 
    <%= hidden_field_tag "user[agent_id]", current_user.id %> 
    <tr>Agent Username<br></tr> 
    <tr><%= text_field_tag "user[agent_username]" %><br></tr> 
    <tr>Email (optional)<br></tr> 
    <tr><%= email_field_tag "user[email]" %><br></tr> 
    ... 
    <% end %> 
<ul> 

    <% @sub_accounts.each do |current_sub_account| %> 
    <%= render 'landing/sub_account_partial', :current_sub_account => current_sub_account %> 
    <% end %> 
</ul> 

/controllers/landing_controller.rb

... 
    @sub_accounts = User.where(:agent_id => current_user.id) 
...

Вы не определил @current_sub_account в вашем создать действие так парциальный становятся передаются нулевым переменным экземпляр.

Вам нужно что-то вроде @current_sub_account = WHATEVER IS YOUR SUB ACCOUNT OBJECT в действии создать
