Redirect to current page rails

Question

I have a sign in form in my application nav bar and I was wondering if there is an easy way to have to sign_in redirect to whatever page you are currently on when you sign_in. Thanks!

Answer 1

You can redirect_to(:back) , as long as a referrer is given. However, I'd recommend that you take a look at this answer , as the solution presented there will be resilient to things like failed logins and OAuth redirects.

Answer 2

在Rails 5中，您应该使用redirect_back并添加回退路径：

redirect_back(fallback_location: root_path)

Answer 3

If you have written the code to create a session for your user ,then simply add this line after that in your sessions_controller:

redirect_to root_url, :notice => "Logged in!"

here instead of root_url you can enter any path you wish the user be redirected to. but make sure you have it in you routes.rb
and if you considering the unsuccessful sign_in you can use render method to reload your sign_in view

Answer 4

This solution from the Devise folks should do the trick...

In ApplicationController write the following:

after_filter :store_location

def store_location
  # store last url - this is needed for post-login redirect to whatever the user last visited.
  return unless request.get? 
  if (request.path != "/users/sign_in" &&
      request.path != "/users/sign_up" &&
      request.path != "/users/password/new" &&
      request.path != "/users/password/edit" &&
      request.path != "/users/confirmation" &&
      request.path != "/users/sign_out" &&
      !request.xhr?) # don't store ajax calls
    session[:previous_url] = request.fullpath 
  end
end

def after_sign_in_path_for(resource)
  session[:previous_url] || root_path
end
