【问题描述】:
为了让用户了解这种情况,我很头疼:
对话模型:
has_many :conversation_participants, :dependent => :destroy
has_many :users,
:through => :conversation_participants
has_many :messages, :dependent => :destroy
has_one :display_message,
:class_name => 'Message',
:order => 'created_at DESC'
def participants(options={})
if options[:not].is_a? User
users - [options[:not]]
else
users
end
end
和 conversation_participants:
belongs_to :user
belongs_to :conversation
attr_accessible :user_id
关于对话助手:
def self_or_other
@conversation.conversation_participants.find_by_user_id(:not => current_user)
end
拜托,有人可以告诉我如何让其他用户进入 conversation_participants 模型?
