I have been trying to find where Devise makes the decision to allow a user to be authorized.
I’m pretty sure (but not certain) this is where Devise ,creates authenticate_user!, user_signed_in?, current_user, and user_session .
~/.rbenv/versions/2.4.1/lib/ruby/gems/2.4.0/gems/devise-4.3.0/lib/devise/controllers/helpers.rb def self.define_helpers(mapping) #:nodoc: mapping = mapping.name
class_eval <<-METHODS, __FILE__, __LINE__ + 1
def authenticate_#{mapping}!(opts={})
opts[:scope] = :#{mapping}
warden.authenticate!(opts) if !devise_controller? || opts.delete(:force)
end
def #{mapping}_signed_in?
!!current_#{mapping}
end
def current_#{mapping}
@current_#{mapping} ||= warden.authenticate(scope: :#{mapping})
end
def #{mapping}_session
current_#{mapping} && warden.session(:#{mapping})
end
METHODS
ActiveSupport.on_load(:action_controller) do
if respond_to?(:helper_method)
helper_method "current_#{mapping}", "#{mapping}_signed_in?", "#{mapping}_session"
end
end
end
``
I use byebug to try to debug things.
Assuming
def authenticate_#{mapping}!(opts={}) opts[:scope] = :#{mapping} warden.authenticate!(opts) if !devise_controller? || opts.delete(:force) end
``
starts on line 114, I have tried
b /home/my-project/.rbenv/versions/2.4.1/lib/ruby/gems/2.4.0/gems/devise-4.3.0/lib/devise/controllers/helpers.rb:115
``
byebug then, quite reasonably, complains "*** Line 115 is not a valid breakpoint in file /home/ … /helpers.rb
“module ClassMethods” can be found at line 15 in /home/my-project/.rbenv/versions/2.4.1/lib/ruby/gems/2.4.0/gems/devise-4.3.0/lib/devise/controllers/helpers.rb
So, I tried (byebug) b ClassMethods#authenticate_user! Successfully created breakpoint with id 3
``
But that does not seem to trip a breakpoint.
Interestingly, byebug seems to accept the following (byebug) b ClassMethods#current_user1 Successfully created breakpoint with id 6
``
even though ClassMethods#current_user1
doesn’t exist.
So, how to I set a breakpoint and spelunk where Devise does its user authorization?
