我正在尝试使用复选框表单编辑多个记录,如this Railscast所示。从那以后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同时编辑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改为同一个东西,但我只是用它来熟悉代码 - 它不起作用!< / p>
这就是我所拥有的:
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 %>
routes.rb中:
resources :people do
collection do
put 'update_multiple'
end
end
和rake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
修改
我的路线搞砸了。它们现在正在如上所示正常工作。

你正在混淆单数和复数资源。 edit_multiple_path
路由当前配置为单一资源,这意味着它期望将单个Person
作为参数传递。但是,根据定义,您尝试一次更新多个人 - 在这种情况下使用单一路由没有意义。
相反,请尝试collection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名.erb
才能解释Ruby代码。也许您已相应地对其进行了命名,但您的帖子描述的名称为edit_multiple.html
,而不是 .erb
。

在submit
上,查看代码检查器并验证您是否已转到GET
请求。
如果你得到一个404导致GET请求而不是PUT请求,那是因为: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。
答案 2 :(得分:0)
你正试图获得这条路线:
没有路线匹配{:controller =&gt;“people”,:action =&gt;“edit_multiple”}
但在route.rb中你包括:id属性是必需的
people /:id / edit_multiple
因此,在表单中,您需要包含人员ID
尝试以下代码来获取此路线{:controller =&gt;“people”,:action =&gt;“edit_multiple”}
resources :people do
collection do
get :edit_multiple
put :update_multiple
end
end
