ArgumentError: wrong number of arguments (3 for 2) #40

Closed mina-samy closed 10 years ago

mina-samy commented 11 years ago

I added the acts_as_relation gem to the gem file, and I have a User class where I included the "acts_as_superclass" statement,

the children of the User class are Admin Swimmer Coach

where I added the "acts_as :user" statement and I added ":as_relation_superclass => true" to my User table DB migration

but this Error appears whenever I try to view the Admin class by writing Admin in the rails console

what am I doing wrong ? sorry for the stupid question but I am a beginner

hzamani commented 11 years ago

Do it work without acts_at :user?

mina-samy commented 11 years ago

how whould it work without acts_as :user ? this way I wont specify the children classes !

hzamani commented 11 years ago

For a test, remove acts_as :user form Admin model and then in console try something like Admin.new

I'm having also the same error after updating to rails 3.2.14, but I don't know if it has something to do with it... here's some lines of the stacktrace:
