ruby on rails - ActionController::RoutingError (No route matches [PUT] ) for ajax call

Question

Hope all is well.

I want to ajax call on _questions_form. It works without remote: true option, yet I am using actioncable and when I submit the form my actioncable data disappeared upon submitting , so I thought making the form with ajax call to prevent that issue.

my _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 %>

my routes.rb

  resources :tasks do   
    collection do
      put :complete
    end      
  end

my _result.js.erb

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

my 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

my 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 %>  

but in console I received such an error

Note: Please if more info is needed, ask me to post them

Answer 1

just remove the :method => :put that you have on your form, if you will create, it needs to be post, but just remove the method part, and it will work.

thats because there is no route to /tasks with put method when you create it with resources
