Question

How do I redirect a user to a specific page when they login on a particular form I create with Devise? There’s this howto page for Devise on how to redirect to a particular page after sign in. However, I want different forms to sign in to different target pages. Ideally, I can just add another HTML form parameter like this:

<input type="hidden" name="target" value="/dashboard"/>

UPDATE: It’s important that I maintain the normal functionality of Devise for a login page. That is, if I click on a link that has a before_filter :authenticate_user! in its controller, then I’ll be redirected to a login page. After logging in, then I’m redirected to the original destination page.

Actually you can simply define the after_sign_in_path_for method in your controller like that :

class ApplicationController < ActionController::Base

  def after_sign_in_path_for
    params[:target] || some_default_url
  end

end

And then if your different sign in forms have different targets, then user should be properly redirected

Adding

<input type="hidden" name="target" value="/dashboard"/>

to each particular form that would redirect to a specific page will then be enough 🙂

EDIT : I think I finally understood what you exactly want. So here what I would do (based on this blogpost)

class ApplicationController < ActionController::Base
  protect_from_forgery

  def after_sign_in_path_for(user)
    origin_path = session[:origin_path]
    clear_origin_path
    if origin_path.present?
      origin_path
    else
      params[:target].presence || default_redirect_path
    end
  end

  private

  def authenticate_user!
    store_origin_path
    super
  end

  def store_origin_path
    session[:origin_path] = request.fullpath
  end

  def clear_origin_path
    session[:origin_path] = nil
  end

end

So basically, if you try to access a protected path (let’s say /protected_resource), the path will be stored in the session, and then once user is logged in, the session will be cleared and user correctly redirected

Then if a user goes on one of your different sign_in form and if that form contains a target input, then user will be redirected to that target.

Finally, if user goes on a form without any target he’ll be redirected to a default_redirect_path that you might want to customize.

Last thing : I assumed that the redirection to the original request was more important than the target so let’s say a user goes on /protected_resource and is therefore redirected to a sign_in form, even though this sign_in form has a target input, user will be redirected to /protected_resource after a successful sign in.

You can easily change that by inverting the conditions in the after_sign_in_path_for method

There might be a better way to do that, but this a starting point for you, and you might want to improve it 😉

Let me know if my answer is not detailed enough.
