Redirect the user to the proper "back" page

awesome_back_url

Redirect to proper back URL for your Rails applications. In case if you want to redirect user not to "edit" or "new" page from "show" after creation, but to "index" or other specific URL.

Usage

Options:

awesome_back_path(path = request.referrer, only: nil, except: nil, fallback: :back)

• "path" - destination to redirect user
• "only" - regexp of allowed paths
• "except" - regexp of disallowed paths
• "fallback" - if path is incorrect (not allowed or not in allowed) redirect to this url.

Samples:

link_to 'Back', awesome_back_path(except: /\/new|\/edit/, fallback: users_path) # returns '/users'
link_to 'Back', awesome_back_path('/path', except: /\/new/, fallback: '/users') # returns  '/path'
link_to 'Back', awesome_back_path('/path/new', except: /\/new|\/edit/, fallback: '/users') # returns '/users'
link_to 'Back', awesome_back_path('/path/edit', except: /\/new|\/edit/, fallback: '/users') # returns '/users'
link_to 'Back', awesome_back_path('/path', only: /\/new|\/edit/, fallback: '/users') # returns '/users'
