ajax 调用的 ActionController::RoutingError (No route matches [PUT] )

Question

希望一切都好。

我想对_questions_form 进行ajax 调用。它可以在没有 remote: true 选项的情况下工作，但是我正在使用 actioncable 并且当我提交表单时，我的 actioncable 数据在提交时消失了，所以我想用 ajax 调用来制作表单防止这个问题。

我的_questions_form.html.erb

<%= form_for complete_tasks_path, :method => :put, :html=>{:remote=>true} do %>
  <ul>
  <% @in_completed_tasks.each do |task| %>
    <li>
      <%= check_box_tag "task_ids[]", task.id %>
      <!--<input type="checkbox" name="task_ids[]" id="task_ids_" value="5">-->
      <%= task.name %>
    </li>
  <% end %>
  </ul>
  <%= submit_tag "Submit your Answers" if @in_completed_tasks.present? %>
<% end %>

我的routes.rb

  resources :tasks do   
    collection do
      put :complete
    end      
  end

我的_result.js.erb

 $('#results').html("<%= j (render partial: 'tasks/questions_form') %>")

我的task_controller

class TasksController < ApplicationController
    def index
        @completed_tasks = Task.complete
        @in_completed_tasks = Task.in_complete
        @answers = Answer.all
    end

    def new
        @task = Task.new
    end

    def create
        @task = Task.create(allowed_tasks_params)
        if @task.save
            flash[:success] =  "Task was saved"
           redirect_to tasks_path
        else
            flash.now[:danger] = "something went wrong"
            render 'new'
        end
    end

    def complete

    #  byebug 
    #  Task.where(id: params[:task_ids]).update_all(complete: true)
    #   debugger 
    ids = params[:task_ids]
    if ids
        ids.each do |id|
            answer = Task.where(id: id).first.name
            Answer.create(feedback: answer)
            ActionCable.server.broadcast 'web_notifications_channel',
                                   message:  answer
        end
    end
    #  Task.update_all(["completed_at=?", Time.now], :id => params[:task_ids])
    #   redirect_to root_path

       respond_to do |format|  
            format.js  
        end  
    end


private 
   def allowed_tasks_params
       params.require(:task).permit(:name, :complete)
   end
end

我的index.html.erb

<h1>All Questions</h1>
<div id="result">
 <%= render partial: 'tasks/questions_form' %>
</div>

<ul>
<% @completed_tasks.each do |c| %>
    <li><%= c.name %></li>
<% end %>
</ul>
<%= link_to "New Question", new_task_path %> 
<hr/>

<h1>All the answers</h1>
  <div id="messages">  
  </div>
<hr /> 
  <%= pie_chart Answer.group(:feedback).count , suffix: "%", refresh: 60 %>  

但在控制台中我收到了这样的错误

注意：如果需要更多信息，请让我发布它们

Answer 1

你的routes.rb应该生成一个路由

PUT /tasks/complete 映射到TasksController#complete

但是你的表单正在做一个

PUT /tasks 改为（来自您的日志），因此请求（即您的表单）有问题

您可以尝试以下方法吗：

resources :tasks do   
   collection do
     post :complete
  end      
end

<%= form_tag complete_tasks_path, format: :js, method: :post, remote: true do %>
  <ul>
    <% @in_completed_tasks.each do |task| %>
      <li>
        <%= check_box_tag "task_ids[]", task.id %>
        <!--<input type="checkbox" name="task_ids[]" id="task_ids_" value="5">-->
        <%= task.name %>
      </li>
    <% end %>
  </ul>
  <%= submit_tag "Submit your Answers" if @in_completed_tasks.present? %>
<% end %>

Answer 2

只需删除表单上的:method => :put，如果要创建，则需要发布，但只需删除方法部分即可。

那是因为当您使用 resources 创建 /tasks 时，没有使用 put 方法的路由
