Question

I have a really hard time understanding routes and I hope someone can help me.

Here’s my custom controller

class SettingsController < ApplicationController
  before_filter :authenticate_user!

    def edit
      @user = current_user
    end

    def update
      @user = User.find(current_user.id)
      if @user.update_attributes(params[:user])
        # Sign in the user bypassing validation in case his password changed
        sign_in @user, :bypass => true
        redirect_to root_path
      else
        render "edit"
      end
    end
end

and I have the file settings/edit.html.erb and my link

<li><%= link_to('Settings', edit_settings_path) %></li>

The route

get "settings/edit"

doesn’t work for this, because then I get

undefined local variable or method `edit_settings_path' for #<#<Class:0x00000001814ad8>:0x00000002b40a80>

What route do I have to give this? I can’t figure it out. If I put “/settings/edit” instead of a path it messes up as soon as I’m on a other resource page because the resource name is put BEFORE settings/edit

Thx

Following should do:

get 'settings/edit' => 'settings#edit', :as => :edit_settings
# you can change put to post as you see fit
put 'settings/edit' => 'settings#update'

If you use /settings/edit directly in link, you shouldn’t have problem with other resource name being prepended in path. However, without the leading slash, i.e. settings/edit it might have that issue.

Reason why edit_settings_path is not working might be because you didn’t declare a named route. You have to use :as option to define by which method you will be generating this path/url.
