Question

我开发了一个应用程序，我的协会似乎遇到了一些问题。我有以下内容：

class User < ActiveRecord::Base
  acts_as_authentic

  has_many :questions, :dependent => :destroy
  has_many :sites , :dependent => :destroy
end

问题

class Question < ActiveRecord::Base
  has_many :sites, :dependent => :destroy
  has_many :notes, :through => :sites
  belongs_to :user
end

网站（将其视为问题的答案）

class Site < ActiveRecord::Base
  acts_as_voteable :vote_counter => true

  belongs_to :question
  belongs_to :user
  has_many :notes, :dependent => :destroy
  has_many :likes, :dependent => :destroy

  has_attached_file :photo, :styles => { :small => "250x250>" }

  validates_presence_of :name, :description

end

创建站点（答案）时，我成功将question_id传递给Sites表，但我无法弄清楚如何传递user_id。这是我的SitesController #create

 def create
       @question = Question.find(params[:question_id])
       @site = @question.sites.create!(params[:site])

       respond_to do |format|
           format.html { redirect_to(@question) }
           format.js
         end
       end

Answer 1

我认为这可以胜任

@question = current_user.questions.find params[:question_id]

如果没有，那么只需指定mannualy。

@site = @question.sites.build(params[:site])
@site.user = current_user
@site.save

将两个变量传递给单独的表...关联问题
