Question

我正在尝试为表单创建多个提交按钮，但我不断收到此错误：

Couldn't find User with id=edit_individual

发现于：

# Use callbacks to share common setup or constraints between actions.
def set_user    
@user = User.find(params[:id])
end

我的控制器页面：

def edit_individual
  if User.find_by_id (params[:user_ids])
    if params[:Delete_multiple]
      @users = User.find(params[:user_ids])
      @users.each do |user|
        user.destroy
      end
      redirect_to :back, notice: 'All selected users were successfuly deleted'
    else
      @users = User.find(params[:user_ids])
    end
  else
    redirect_to :back, alert: 'No users were selected for editing'
  end
end

def update_individual

  @users = User.update(params[:users].keys, params[:users].values).reject { |p| p.errors.empty? }
    if @users.empty?
      redirect_to :back, notice: "Users updated"
    else
    render :action => "edit_individual"
    end

end

我的索引页：

<%= form_tag edit_individual_users_path do %>
<table class="table table-hover">
  <thead>
    <tr>
      <th></th>
      <th><%= sort_link @q, :firstName, "First name" %></th>
      <th><%= sort_link @q, :lastName, "Last name" %></th>
      <th><%= sort_link @q, :registrationNumber, "Registration number" %></th>
      <th><%= sort_link @q, :email, "Email" %></th>
      <th></th>
     </tr>
  </thead>
  <tbody>
    <% @users.each do |user| %>
    <% if (user.archive == false) %>
      <tr>
      <td><%= check_box_tag "user_ids[]", user.id %></td>
      <td><%= user.firstName %></td>
      <td><%= user.lastName %></td>
      <td><%= user.registrationNumber %></td>
      <td><%= user.email %></td>
      <td><%= link_to 'View', user, class: 'btn btn-info btn-mini', title: 'View users\'s information' %></td>
      <td><%= link_to 'Edit', edit_user_path(user), class: 'btn btn-warning btn-mini', title: 'Edit users\'s information', method: 'get' %></td>
      <td><%= link_to 'Delete', user, class: 'btn btn-danger btn-mini', title: 'Delete user', method: :delete, data: { confirm: 'Are you sure?' } %></td>
      </tr>
    <% end %>
    <% end %>
  </tbody>
  </table>
  <p><%= select_tag :field, options_for_select([["All Fields", ""], ["First name", "firstName"], ["Last name", "price"], ["Registration number", "registrationNumber"], ["Email", "email"]]) %></p>

<p><%= submit_tag "Edit checked", name: 'Edit_multiple' %></p>
<p><%= submit_tag "Delete checked", name: 'Delete_multiple', data: { confirm: 'Are you sure you want to delete multiple users?' } %></p>
<% end %>

edit_individual页面：

<% form_tag update_individual_users_path, :method => :put do %>
  <% for product in @products %>
    <% fields_for "users[]", users do |f| %>
      <h2><%=h user.name %></h2>
      <%= render :partial "fields", :locals => { :f => f, :user => user } %>
    <% end %>
  <% end %>
  <p><%= submit_tag "Submit" %></p>
<% end %>

路线档案：

resources :users do
  get 'archive', on: :collection
  post 'edit_individual', on: :collection
  put 'update_individual', on: :collection
end

删除部分工作正常。此外，编辑部分实际上编辑了该字段，但显示该错误（因此它不会重定向回索引页面，使其看起来很糟糕）。

任何人都可以帮我解决这个问题吗？我花了很多时间同时拥有edit和delete所以如果我不得不删除编辑部分会非常糟糕。

编辑1：此外，如果我正在编辑3个用户并单击提交按钮，只允许2/3通过（由于验证），则没有错误（我只是被重定向回edit_individual.html完成最后一个用户）然后如果我再次点击提交并且一切都通过，我就会收到错误。

Answer 1

我确实设法找到了什么问题。问题在于：

def update_individual

  @users = User.update(params[:users].keys, params[:users].values).reject { |p| p.errors.empty? }
  if @users.empty?
    redirect_to :back, notice: "Users updated"
  else
    render :action => "edit_individual"
  end

end

而不是：

redirect_to :back

应该是：

redirect_to users_path

或者我认为的任何其他固定路径。有没有办法保持＆＃34; redirect_to：back＆＃34;，或者我是否必须为将使用它的其他视图（在同一个控制器中）创建新方法？

Answer 2

它不应该运行，因为你没有params[:id]

如果您使用before_filter，那么

before_filter: set_user except: [:update_individual, :edit_individual]

def set_user    
 @user = User.find(params[:id])
end

您在update_individual

中致电edit_individual的地方

多个提交按钮栏
