Question

我正在尝试从实验室控制器的索引操作将数据插入Subscriber。这是我的代码。

查看HTML：

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

主控制器

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

订户控制器

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

的routes.rb

不要将form_for包裹在<form></form>标记内。当你点击＆＃34;提交＆＃34;它返回标记的简单GET请求而不是form_for rails helper（已禁用）。

<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>
