No route matches [POST] "/chat_rooms/1"

Question

I am trying to make a direct messaging app using rails and I have been facing this problem whenever I try to send any message. When I submit the form it gives me this error:

No route matches [POST] "/chat_rooms/1"

my new.html.erb is:

  <%= form_for @chat_room do |f| %>
    <div class = "form-group">
        <%= f.label :title %>
        <%= f.text_field :title, autofocus: true, class: 'form-control' %>
    </div>
    <%= f.submit "Add!" ,class: 'btn btn-primary' %>

And my controller file is:

class ChatRoomsController < ApplicationController
 
def index
    @chat_rooms = ChatRoom.all
end

def new 
    @chat_room =  ChatRoom.new
end

def create
    @chat_room = current_user.chat_rooms.build(chat_room_params)
    if @chat_room.save
        flash[:success] = 'Chat room added'
        redirect_to chat_rooms_path
    else
        render 'new'
    end
end

def show
    @chat_room = ChatRoom.includes(:messages).find_by(id: params[:id])
    @message = Message.new
end

private
def chat_room_params
    params.require(:chat_room).permit(:title)
end

end

<% end %>

my routes.rb is:

 Rails.application.routes.draw do
  devise_for :users
  resources :chat_rooms, only: [:new, :create, :show, :index] 
  root 'chat_rooms#index'
  mount ActionCable.server => '/cable'
end

What is your output when typing `rake routes`? Also just to double check, after updating your `routes.rb` did you restart your server? — jdgray, Jul 05 '18 at 15:18
Can you show server log of the request that renders your new chat room form? — Jagdeep Singh, Jul 05 '18 at 15:25
I mean the ones starting with "Started GET '/chat_rooms/new'" or something — Jagdeep Singh, Jul 05 '18 at 15:53
Are you using action cable when creating new chat rooms? There's nothing wrong with your basic implementation. — Mark Merritt, Jul 05 '18 at 16:23
Try commenting out the action cable code. If it works, I would suggest closing this question and posting a new question with the relevant action cable code. — Mark Merritt, Jul 05 '18 at 16:50

You should specify the url in your form :

<%= form_for @chat_room, url: chat_rooms_path, method: :post do |f| %>

What HTML does that `form_for` generate? edit your post to add the above suggestion, and add the HTML that's generated. – Phlip Jul 05 '18 at 15:48

Seems like you forgot to add routes. You've to add update action to your routes.

Modify this to:

resources :chat_rooms, only: [:new, :create, :show, :index]

to this:

resources :chat_rooms, only: [:new, :create, :show, :index, :update]

Also, add update action to the controller:

def update
    respond_to do |format|
      if @class_room.update(chat_room_params)
        format.html { redirect_to @chat_room, notice: 'Chat Room was successfully updated.' }
        format.json { render :show, status: :ok, location: @chat_room }
      else
        format.html { render :edit }
        format.json { render json: @class_room.errors, status: :unprocessable_entity }
      end
    end
end

There should still be **no** route [POST] "/chat_rooms/1". – Jagdeep Singh Jul 05 '18 at 16:19
Yes, This looks suspicious now. The URL seems to be for update action but is a POST request. – Abhilash Reddy Jul 05 '18 at 16:28

Specify action inside url and try.

  <%= form_for @chat_room,  url: {action: "create"} do |f| %>
    <div class = "form-group">
        <%= f.label :title %>
        <%= f.text_field :title, autofocus: true, class: 'form-control' %>
    </div>
  <%= f.submit "Add!" ,class: 'btn btn-primary' %>

No route matches [POST] "/chat_rooms/1"
