Hello,
i have a strange problem here. I have made a teacher controller using
scaffold. All actions work fine but the delete does not. When i click
the delete link, it redirects me to the edit of this teacher. I have
restarted the server and i have tried in firefox (i use chrome) but
problem still remains. Here is the code from my view.
<%= link_to ‘Delete’, teacher, :confirm=>“Are you
sure?”, :method=>:delete %>
The teacher_controller action is:
DELETE /teachers/1
DELETE /teachers/1.xml
def destroy @teacher = Teacher.find(params[:id]) @teacher.destroy
respond_to do |format|
format.html { redirect_to(teachers_url) }
format.xml { head :ok }
end
end
In the routes i only use resources :teachers.
Any sollution with that??
Thank u i advance.

Have a look in the log file (log/development.log) to see what is
logged when you click the link
Sounds like you don’t have any javascript files in your Rails app.
Remember that the destroy method uses javascript to work correctly. If
javascript is missing, then the browser sends a POST request to your
Rails server. If you send a post request to an existing record, you get
the edit action.
Make sure you have your javascript files included in
config/application.rb
Oops. Correction on the above answer. It should be GET instead of POST.
If there is no javascript, the delete link sends a get request to your
server. A get request on an existing record gives you the edit action.

Hi Arailsdemo,

edited this file. The only thing i have inside is:
require File.expand_path(’…/boot’, FILE)
require ‘rails/all’
Bundler.require(:default, Rails.env) if defined?(Bundler)
module Ptixiakes
class Application < Rails::Application
config.encoding = “utf-8”
config.filter_parameters += [:password]

Well there is no POST for the delete apparently. At what point in the
above did you click the delete link? If you are not sure then repeat
it and note the times that you do things. Leave a bit between actions
if necessary.
Have you checked the html for your link to make sure it looks ok (View

I had this same problem when starting a new Rails 3 project with
jQuery. (I generated this project using a template from the Rails
Wizard website.)
If you are using jQuery, make sure you have the correct rails.js file
(the jquery-rails gem will add rake tasks to help manage this).
Also make sure that the jquery.min file is being loaded with the
rails.js file
My layout was using “javascript_include_tag :defaults”, but only my
rails.js file was getting loading.
I fixed this by updating the config/application.rb file and modifying
the “config.action_view.javascript_expansions[:defaults]” setting to
add jquery.min.

Can you confirm whether you see the Are You Sure popup? If not then,
as others have suggested, there is an issue with the javascript.
Check that you have
<%= javascript_include_tag :defaults %>
in the layout (application.html.erb unless you have provided your own
layout).
