Error shown when generating models in RoR, wrong number of arguments in model

Question

I'm new in RoR. I'm learning models and generating the models for my app and it's associations. The console generated the error when I tried:

$ rails console

mypath.rbenv/versions/2.3.3/lib/ruby/gems/2.3.0/gems/activerecord-5.1.3/lib/active_record/associations.rb:1395:in `has_many': wrong number of arguments (given 4, expected 1..3) (ArgumentError)

and more lines of errors but this one is the key I think.

Answer 1

Solved it, I was writing on the same line different associations which is not correct:

Wrong:

class User < ApplicationRecord
  # Include default devise modules. Others available are:
  # :confirmable, :lockable, :timeoutable and :omniauthable
  devise :database_authenticatable, :registerable,
         :recoverable, :rememberable, :trackable, :validatable

  has_many :questions, :answers, :comments, :votes
end

Correct:

class User < ApplicationRecord
  # Include default devise modules. Others available are:
  # :confirmable, :lockable, :timeoutable and :omniauthable
  devise :database_authenticatable, :registerable,
         :recoverable, :rememberable, :trackable, :validatable
  has_many :questions
  has_many :answers
  has_many :comments
  has_many :votes

end
