if you are building athentication from scratch this method can be accessed
by the controller and views by putting that method in the
application_controller and adding
def current_user
@current_user ||= User.find(session[:user_id]) if session[:user_id]
end
helper_method :current_user
this will make it available to other controllers and views, session data is
not accesible from the models.
What you want to do is done with a before filter in the controller like
this:
at the top of the controllers you add
before_filter :check_if_cool_enough
at the bottom
private
def check_if_cool_enough
if current_user.admin?
flash[:notice] = "YOU ARE SOOO COOL"
else
flash[:error] = "omg, lol noob"
redirect_to root_path
end
end
