Hi everyone,
I ran into some problems when modeling mailbox and mails. My code was
like:
create_table :mailbox do |t|
t.integer :user_id # the owner of this mailbox
end
create_table :mails do |t|
t.integer :sender_id
t.integer :receiver_id
t.string :title
t.text :content
end
class Mailbox < ActiveRecord::Base
belongs_to :user
has_many :sent_mails,
:class_name => ‘mail’,
:conditions => { :sender_id => self.user_id } # I know this
is wrong
has_many :recv_mails,
:class_name => ‘mail’,
:conditions => { :receiver_id => self.user_id }
end
I know this is wrong. because user_id is an instance method and self
refers to the class object. My question is how to fix this problem?
Thanks in advance
