ruby-on-rails-3 - 设计 rails 将 user_id 添加到另一个模型

Question

我想将 current_user.id 从设计添加到另一个模型...

问题模型:

    class Question < ActiveRecord::Base
  belongs_to :user
  attr_accessible :content

  validates :content, :presence => true
end

用户模型:

    class User < ActiveRecord::Base
  has_many :questions
  # Include default devise modules. Others available are:
  # :token_authenticatable, :encryptable, :confirmable, :lockable, :timeoutable and :omniauthable
  devise :database_authenticatable, :registerable,
         :recoverable, :rememberable, :trackable, :validatable

  # Setup accessible (or protected) attributes for your model
  attr_accessible :email, :password, :password_confirmation, :remember_me
end

我的问题迁移:

class CreateQuestions < ActiveRecord::Migration
  def change
    create_table :questions do |t|
      t.string :content
      t.date :deadline
      t.integer :user_id

      t.timestamps
    end
  end
end

在我的问题 Controller 中:

def create

    params[:question][:user_id]=current_user.id

    @question = Question.new(params[:question])
    if @question.save
      redirect_to questions_path, :notice => "Successfully created question."
    else
      setup_questions
      render :index
    end
  end

当我保存问题时，current_user.id 不会记录在我的数据库中吗？

试试这个:

def create

  @question = Question.new(params[:question])
  @question.user_id = current_user.id
  if @question.save
    redirect_to questions_path, :notice => "Successfully created question."
  else
    setup_questions
    render :index
  end

end
