Switch_back as a link

[firedev]

Is there a simple way to detect that I have switched to a user and display a switch_back link? I tried to check for original_user in the view, but it doesn't work this way.

Internally, I use session[:original_user] to store the original user. Checking to see if that exists will tell you if you've switched from another user.

FYI This is definitely going to change because I definitely shouldn't be storing the whole user object in the session.

HTH

Hi, you mean you're storing the whole user object? I think it would be ok to store just the ID.

[firedev]

Just checked it, session[:original_user] is always nil

[lcowell]

Examine the entire session variable if you can. It may be under session[:original_user_scope_identifier] at this point in time.

Added session[:original_user_scope_identifier].inspect to application layout. It's always nil as well.

Hmmmm are you using the switch_back feature ? You can read about it in the read me.

Hmm I think yes, here is an excerpt from my initializers/switch_user.rb:

  config.switch_back = true
  config.controller_guard = ->(current_user, request, original_user) do
    current_user && current_user.can_supervise? || original_user && original_user.can_supervise?
  end

try this in your switch_user.rb

SwitchUser.setup do |config|
  config.switch_back = true
  config.controller_guard = lambda { |current_user, request, original_user|
      current_user && (current_user.has_role? :admin) || original_user && (original_user.has_role? :admin)
    }
end

and then something like this in your view

<%if current_user.present? %>
    <% if (current_user.has_role? :admin) or (session[:original_user_scope_identifier].present?) %>
        <%= switch_user_select %>
    <% end %>
<% end %>
