Rails не может вставить данные в базу данных

Question

Я пытаюсь вставить данные в подписчик с помощью действия index контроллера labs.Это мой код.

Просмотр HTML:

<div class="container">
  <form id="login">
    <div class="subscribe">
         <%= form_for @subscriber, :url => url_for(:controller => "subscribers", :action => "create" ), remote: true do |f| %>
            <%= f.label :name, 'SUBSCRIBE TO OUR NEWSLETTER' %>&nbsp;&nbsp;&nbsp;
                    <div id="subscribe-text">
            <%= f.email_field :email_address,placeholder: "email address",row:"3", :class => 'email_class' %>&nbsp;&nbsp;&nbsp;
          </div>
        <%= f.submit "Subscribe", :class => 'button_class' %>
              <% end %>
      </form>
      </div>

            </div>

Главный контроллер

class LabsController < ApplicationController
  layout "labs"
  def index
    @subscriber = Subscriber.new
  end
end

Контроллер абонента

class SubscribersController < ApplicationController

  def create
    @subscriber=Subscriber.new(subscriber_params)
    if @subscriber.save
      redirect_to root_path, notice: "Subscribed Successfully !"
    else
      redirect_to root_path, notice: "Subscription Failed !"
    end
  end

private
  def subscriber_params
    params.require(:subscriber).permit(:email_address)
  end
end

rout.rb

Rails.application.routes.draw do
  resources :subscribers
  root 'labs#index'
  get "home", :to => "labs#index"
end

Вывод в консоль

Не переносите form_for внутри <form></form> разметки.Когда вы нажимаете «Submit», он возвращает простой GET-запрос на разметку, а не на form_for rails helper (который отключен).

<div class="container">
  <%= form_for @subscriber, url: url_for(controller: "subscribers", action: "create" ), remote: true, html: { id: 'login' } do |f| %>
    <%= f.label :name, 'SUBSCRIBE TO OUR NEWSLETTER' %>&nbsp;&nbsp;&nbsp;
    <div id="subscribe-text">
      <%= f.email_field :email_address, placeholder: "email address",row: "3", class: 'email_class' %>&nbsp;&nbsp;&nbsp;
    </div>
    <%= f.submit "Subscribe", class: 'button_class' %>
  <% end %>
</div>
