Question

我在提交表单后收到ActiveRecord::UnknownAttributeError。行unknown attribute: conversation_id

上的错误为@question = @conversation.questions.new(params[:question])

我在属性中添加了conversation_id，但没有进行更改。不确定错误可能指向的是什么。

问题控制员：

  def create
    @conversation = Conversation.create
    @question = @conversation.questions.new(params[:question])
      if @question.save
        @message = current_user.messages.new(:subject => "You have a question from #{@question.sender_id}",
                               :body => @question.question)
        @question.message = @message
        @question.save
        redirect_to :back, notice: 'Your question was saved successfully. Thanks!'
      else
        render :new, alert: 'Sorry. There was a problem saving your question.'
      end
    end
  end

会话模型：

class Conversation < ActiveRecord::Base
  acts_as_messageable

  attr_accessible :answer, :question, :sender_id, :recipient_id, :conversation_id

  has_many :questions

end

用户模型：

  attr_accessible :role, :notification_id, :sender_id, :receiver_id, :conversation_id, :no_email, :average_response_time, :response_rate, :response_total, :name, :time_zone, :code, :lat, :lon, :city, :age, :age_end, :password_confirmation, :about_me, :feet, :inches, :password, :birthday, :career, :children, :education, :email, :ethnicity, :gender, :height, :name, :password_digest, :politics, :religion, :sexuality, :user_drink, :user_smoke, :username, :zip_code

问题模型：

class Question < ActiveRecord::Base
  attr_accessible :answer, :question, :sender_id, :recipient_id, :conversation_id
  belongs_to :user

  belongs_to :sender,:class_name => 'User',:foreign_key => 'sender_id'

  belongs_to :recipient,:class_name => 'User',:foreign_key => 'recipient_id'

  belongs_to :message

  belongs_to :conversation


  end

您正在接收以下行<{1}}

ActiveRecord::UnknownAttributeError - unknown attribute: conversation_id

因为您没有在@question = @conversation.questions.new(params[:question])表格中创建conversation_id字段，因为您在questions和Conversation模型之间设置了1-M关联，所以这是必需的。

要解决此错误，您需要在Question表格中添加conversation_id字段。

提交表单时出现ActiveRecord :: UnknownAttributeError
