Rails 4:单击提交按钮后在div中渲染部分

标签: ruby-on-rails ruby redirect submit partial

我没有得到它。我正在构建rails应用程序并希望执行一些单页操作。我现在得到的是,当我挑选一位顾客时,从customers / index.html.erb上的列表中,我在' current_customer'中呈现它。 DIV。当我点击编辑时,表单会在' current_customer'中呈现。 - 完美。但是当我点击表单上的sumbit时,我得到一个错误(我理解)' ActionController :: UnknownFormat'因为控制器的动作是“显示”。我已经转到' http://localhost:3000/customers/2' 我想要的是路由到' http://localhost:3000/customers'在clikcing sumit之后,在&current; customer'中渲染cutomers / _show.html.erb。格。

我的代码: 客户/ index.html.erb

<h1>Listing Customers</h1>

<table>
  <thead>
    <tr>
      <th>Name</th>
      <th colspan="3">Actions</th>
    </tr>
  </thead>

  <tbody>
    <% @customers.each do |customer| %>
      <tr>
        <td><%= customer.name %></td>
        <td><%= link_to 'Show', customer, remote: true %></td>
        <td><%= link_to 'Edit', edit_customer_path(customer), remote: true %></td>
        <td><%= link_to 'Destroy', customer, method: :delete, data: { confirm: 'Are you sure?' } %></td>
      </tr>
    <% end %>

  </tbody>
</table>

<br>
<div id="current_customer"></div>
<br>

<%= link_to 'New Customer', new_customer_path, class: "button", id: "new_customer" %>

客户/ _show.html.erb

<p>
  <strong>Name:</strong>
  <%= @customer.name %>
  <%= @customer.id %>
</p>

<%= link_to 'Edit Customer', edit_customer_path(@customer) %> |

客户/ _edit.html.erb

<h1>Editing Customer</h1>

<%= render 'form' %>

<%= link_to 'Show', @customer %> |

客户/ _form.html.erb

<%= form_for(@customer) do |f| %>
  <% if @customer.errors.any? %>
    <div id="error_explanation">
      <h2><%= pluralize(@customer.errors.count, "error") %> prohibited this customer from being saved:</h2>

      <ul>
      <% @customer.errors.full_messages.each do |message| %>
        <li><%= message %></li>
      <% end %>
      </ul>
    </div>
  <% end %>

  <div class="field">
    <%= f.label :name %><br>
    <%= f.text_field :name %>
  </div>
  <div class="actions">
    <%= f.submit id: "customer_button", remote: true %>
  </div>
<% end %>

客户/ edit.js.erb

$("#current_customer").html("<%= escape_javascript(render partial: 'customers/edit', locals: { customer: @customer } ) %>");

customers_controller.rb(部分)

def show
    respond_to do |format|
      format.js {render layout: false}
    end
  end

  # GET /customers/new
  def new
  end

  # GET /customers/1/edit
  def edit
    respond_to do |format|
      format.js {render layout: false}
    end
  end

def update
    respond_to do |format|
      if @customer.update(customer_params)
        format.html { redirect_to @customer, notice: 'Customer was successfully updated.' }
        format.json { render :show, status: :ok, location: @customer }
      else
        format.html { render :edit }
        format.json { render json: @customer.errors, status: :unprocessable_entity }
      end
    end
  end

您需要将remote: true放入form_for标记而不是submit按钮,在此处添加

<%= form_for @customer, remote: true do |f| %>

中删除它
<%= f.submit id: "customer_button" %>

此外,update操作也应接受AJAX请求,创建update.js.erb模板并在使用remote: true

提交表单时处理AJAX请求

希望有所帮助!

按原样提交表单将致电POST /customer/1。您需要在控制器和路由中定义更新方法,并将method: :patch添加到表单中以实现PATCH /customer/1

此外,您可能希望定义update.js.erb并在表单中添加remote: true以添加一些动态AJAX。

您可以通过以下方式替换您的节目链接:

<%= link_to "show", {:action => :show}, :remote => true %>

<%= link_to "show", customer_path(customer), :remote => true %>
