How to root to the current user's show view in Rails?

Question

How can I root to the current user's show view in a Rails app?

I want to do something like

authenticated :user do
    root :to => "users#show"
end

but how do I pass the current user's ID into this?

Thanks

Answer 1

I did a before_filter where I check if request.path == root_path and if so I redirect to the path that should be user-specific root. The root_path set in routes.rb is not user-specific root for any user so there is no infinite redirection. Just do flash.keep to make your flash messages survive the redirection.

EDIT: Reading Q&A and comments, trying to understand what you already has, and what you still need. Did you succeed to setup routing to get show action rendered without the :id in the URL? If so maybe you need something like this in your controller show action:

if params[:id].nil? # if there is no user id in params, show current one
    @user = current_user
else # if there is the user id in params just use it, 
     # maybe get 'authorization failed'
    @user = User.find params[:id]
end

The following worked for me.

In routes.rb:

root to: 'users#current_user_home'

In users_controller.rb:

def current_user_home
  redirect_to current_user
end
