我有4个表:问题,答案,用户和查询(所有这些表之间的关系表)
这个my_controller
def index
question_id = params[:id].to_i
question = Question.find(question_id)
@answers = question.answers
respond_to do |format|
format.ext_json { render :json => @answers.to_ext_json(:class =>
Answer) }
end
end
我在extjs中有网格,当我点击行时,我得到答案 我刚刚选择的问题,COOL。但我需要粘贴此信息电子邮件 人(用户表中的电子邮件存储)。现在我有了这个:
| id | answer |
1 | lala
2 | lalala2
但我需要这个:
| id | answer | email
1 | lala | alal@sa.com
2 | lal2 | asasa@was.net
P.S
users (table): id, email
questions (table): id, text
inquiries: question_id, user_id
answers: inquiry_id, text
用户模型:
has_many :inquiries
has_many :questions, :through => :inquiries
has_many :answers, :through => :inquiries
问题模型:
has_many :inquiries, :dependent => :destroy
has_many :answers, :through => :inquiries, :dependent => :destroy
回答模型
belongs_to :inquiry
belongs_to :question
查询模式
belongs_to :question
belongs_to :users
has_one :answer, :dependent => :destroy
答案 0 :(得分:0)
你需要这样的东西:
在答案模型中
has_one :user, :through => :inquiries
