我正在尝试使用此 Railscast中所示的复选框表单编辑多条记录。从那时起,Rails 发生了变化,我在路由和表单方面遇到了麻烦。

我有一个 PeopleController,我正在尝试制作一个可以一次编辑他们所有电话号码的表单。是的,我知道这不是一个有用的功能,因为通常没有理由将每个人的电话号码更改为相同的东西,但我只是使用它来熟悉代码 - 它不起作用!

这是我所拥有的:

people_controller:

class PeopleController < ApplicationController
  helper_method :sort_column, :sort_direction

  def index
    @people = Person.order(sort_column + " " + sort_direction)

    respond_to do |format|
      format.html # index.html.erb
      format.json { render json: @people }
    end
  end

  # GET /people/1
  # GET /people/1.json
  def show
    @person = Person.find(params[:id])

    respond_to do |format|
      format.html # show.html.erb
      format.json { render json: @person }
    end
  end

  # GET /people/new
  # GET /people/new.json
  def new
    @person = Person.new

    respond_to do |format|
      format.html # new.html.erb
      format.json { render json: @person }
    end
  end

  # GET /people/1/edit
  def edit
    @person = Person.find(params[:id])
  end

  # POST /people
  # POST /people.json
  def create
  ...
  end

  # PUT /people/1
  # PUT /people/1.json
  def update
  ...
  end

  def update_multiple
    @people = Person.find(params[:people_ids])
    @people.each do |person|
      person.update_attributes!(params[:person].reject { |k,v| v.blank? })
    end
    flash[:notice] = "Updated people"
    redirect_to people_path
  end

  # DELETE /people/1
  # DELETE /people/1.json
  def destroy
  ...
  end

  private

  def sort_column
    Person.column_names.include?(params[:sort]) ? params[:sort] : "name"
  end

  def sort_direction
    %w[asc desc].include?(params[:direction]) ? params[:direction] : "asc"
  end

end

index.html.erb:

<h1>Listing people</h1>
<% form_tag edit_multiple_people_path do %>
<table>
  <tr>
    <th></th>
    <th><%= sortable "name" %></th>
    <th><%= sortable "phone" %></th>
    <th><%= sortable "created_at" %></th>
    <th></th>
    <th></th>
    <th></th>
  </tr>

<% @people.each do |person| %>
  <tr>
    <td><%= check_box_tag "people_ids[]", person.id %></td>
    <td><%= person.name %></td>
    <td><%= person.phone %></td>
    <td><%= person.created_at %></td>
    <td><%= link_to 'Show', person %></td>
    <td><%= link_to 'Edit', edit_person_path(person) %></td>
    <td><%= link_to 'Destroy', person, method: :delete, data: { confirm: 'Are you sure?' } %></td>
  </tr>
<% end %>
</table>
<% # submit_tag "Edit Checked" %>
<% end %>
<br />

<%= link_to 'New Person', new_person_path %>

edit_multiple.html.erb:

<%= form_for :person, :url => update_multiple_path, :html => { :method => :put } do |f| %>
  <ul>
    <% @people.each %>
      <li>
        <%= hidden_field_tag "people_ids[]", person.id %>
        <%=h person.name %>
      </li>
    <% end %>
  </ul>

  <p>
    <%= f.label :phone %><br />
    <%= f.text_field :phone %>
  </p>

  <p><%= f.submit "Submit" %></p>
<% end %>

路线.rb:

  resources :people do
    collection do
      put 'update_multiple'
    end
  end

和耙路线:

update_multiple_people PUT    /people/update_multiple(.:format) people#update_multiple
                people GET    /people(.:format)                 people#index
                       POST   /people(.:format)                 people#create
            new_person GET    /people/new(.:format)             people#new
           edit_person GET    /people/:id/edit(.:format)        people#edit
                person GET    /people/:id(.:format)             people#show
                       PUT    /people/:id(.:format)             people#update
                       DELETE /people/:id(.:format)             people#destroy

编辑:

我的路线一团糟。它们现在可以正常工作,如上所示。

您将单数和复数资源混为一谈。该edit_multiple_path路由当前配置为单个资源,这意味着它期望单个Person作为参数传递。但是,根据定义,您试图一次更新多个人——在这种情况下,使用单一路由是没有意义的。

相反,请尝试收集路线:

# config/routes.rb
resources :people
    collection do
        post 'update_multiple/:people_ids', :action => 'update_multiple'
    end
end

这将使以下路线可用:

       update_multiple_invites POST   /invites/update_multiple/:people_ids(.:format) invites#update_multiple

编辑:

在索引视图中,您需要输出表单才能显示它们:

# app/views/people/index.html.erb
<%= form_tag edit_multiple_people_path do %>

# app/views/people/_edit_multiple.html.erb
<%= form_for :person, :url => update_multiple_people_path, :html => { :method => :put } do |f| %>

请注意,<% %>解释其中包含的所有内容,但不输出它。您需要使用<%= %>才能实际输出表单的内容。

另外,不要忘记您的部分需要扩展.erb才能解释 Ruby 代码。也许您已相应地命名它,但您的帖子描述的名称edit_multiple.html 没有.erb.

submit查看代码检查器并验证您是否被路由到请求GET

如果您收到 404 导致 GET 请求而不是 PUT 请求,那是因为该:method => :put选项依赖于 JavaScript。您需要确保jquery-rails已正确集成到您的应用中。

您正在尝试获取此路线:

没有路线匹配 {:controller=>"people", :action=>"edit_multiple"}

但在 route.rb 你包括 :id 属性女巫是必需的

people/:id/edit_multiple

所以在表格中你需要包含个人ID

尝试以下代码来获取这条路线 {:controller=>"people", :action=>"edit_multiple"}

resources :people do               
 collection do         
  get :edit_multiple       
  put :update_multiple       
 end        
end
