【问题描述】:
我没听懂。我正在构建一个 Rails 应用程序并想做一些单页操作。我现在得到的是,当我从customers/index.html.erb 的列表中选择一个“客户”时,我将它呈现在“current_customer”div 中。当我单击编辑时,表单将呈现在“current_customer”中 - 完美。但是,当我单击表单上的 sumbit 时,由于“显示”控制器中的操作,我收到一个错误(我理解)“ActionController::UnknownFormat”。我被路由到'http://localhost:3000/customers/2' 我想要的是在点击 sumit 并在 'current_customer' div 中渲染 cutomers/_show.html.erb 后路由到 'http://localhost:3000/customers'。
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
我很乐意为您提供任何帮助! 谢谢
【问题讨论】:
-
显然,你需要使用AJAX。
-
你遇到了什么错误?
-
ActionController::UnknownFormat in CustomersController#show - app/controllers/customers_controller.rb:12:in `show'
-
你有更新操作对吗?
-
是(见代码中的编辑)
