Deleting a public folder or file from a Rails3 view?

Question

I have a user model where users can upload their profile image, using the Paperclip gem. This all works fine and stores the file in the /public/images/#{user.id}/medium or original or small directory.

However I need to create an method to be able to delete these files, could someone help me with this?

Here is the code I have so far:

app/views/users/index.html.erb:

<%= link_to "Delete", method: :file_cleanup, action: :destroy %>

app/controllers/users_controllers.rb:

def file_cleanup
    File.delete(Rails.root + 'public/#{current_user.image.url}')
    redirect_to :action => :edit
end

I have not added any routes as the page seems to load without any errors.

you will need to change your `link_to` to this: `<%= link_to "Delete", controller: "users", action: "file_cleanup" %>` — dennismonsewicz, Oct 11 '13 at 13:58
that gives a route error "No route matches {:controller=>"users", :action=>"file_cleanup"}" — Jon, Oct 11 '13 at 14:00

It should be as simple as:

def delete_image
  @user.image.destroy
end

I'd use that as a hook like before_destroy :delete_image.
