Rails: Route Error while trying to update attribute through link_to

Question

ERROR: No route matches [GET] "/bookings/:id/%3E:format"

I want to update an attribute when click on link of 'link_to'..

<%= link_to 'Cancel', '/bookings/:id/(.:format)' %>

routes.rb

put '/bookings/:id/(.:format)' => "bookings#tocancel"
patch '/bookings/:id/(.:format)' => "bookings#tocancel"

controller

def tocancel
 @booking = Booking.find(params[:id])
 @booking.update_attribute(:status, "cancel")
 respond_to do |format|
  format.html { redirect_to @booking, notice: 'Booking was successfully cancelled.' }
  format.json { render :show, status: :ok, location: @booking }

end

You don't pass the URL format to link_to. You can use the helper method bookings_path and pass the @booking object. Read the (excellent) documentation about it: http://guides.rubyonrails.org/routing.html — MrWillihog, Jun 30 '16 at 10:31
`<%= link_to 'Cancel', 'complete_url/bookings/pass_id_value_here' %>` pass id value in `:id` place. — Narasimha Reddy - Geeker, Jun 30 '16 at 10:32
<%= link_to 'Cancel', tocancel_booking_path(booking) %> ERROR :No route matches [GET] "/bookings/36/tocancel" — srihari sairam Ventrapragada, Jun 30 '16 at 11:42

create a method in bookings controller as:

def tocancel
 @booking = Booking.find(params[:id])
 @booking.update_attribute(:status, "cancel")
 respond_to do |format|
  format.html { redirect_to @booking, notice: 'Booking was successfully cancelled.' }
  format.json { render :show, status: :ok, location: @booking }
 end
end

Routes for this would be:

resources :bookings do
  member do
   get :tocancel
  end
end

Cancel link can be created as:

link_to "Cancel", tocancel_booking_path(booking.id)

Here you should have booking_id passed to cancel link. Now check how you get booking_id on the page where you put this cancel link. Let me know if any issue.

Can you give me the url of the page where you are adding this link. you need to retrieve booking_id in that page and pass to this cancel link.. – SnehaT Jun 30 '16 at 10:47
here is the link active.html.erb [link] (https://drive.google.com/file/d/0B-cw8FVV0gUeSENXWGlrbW1HNVU/view?usp=sharing) – srihari sairam Ventrapragada Jun 30 '16 at 10:59
The link seems to be right...try passing booking id instead of object something like booking.id – SnehaT Jun 30 '16 at 11:15
i passed booking then its takes id but shows no route mathches..ERROR:No route matches [GET] "/bookings/36/tocancel" – srihari sairam Ventrapragada Jun 30 '16 at 11:18
Please make the patch to get routes....as we are not taking any params along with url...so get would work... – SnehaT Jun 30 '16 at 11:43
please tell me how can i change it – srihari sairam Ventrapragada Jun 30 '16 at 11:48
