未定义的<fieldname> ActionItem错误

Question

我收到以下错误：

未定义方法`comments=‘

代码如下：

correspondence_controller.rb

class CorrespondenceController < ApplicationController
  protect_from_forgery
  def add
    correspondence = ActionItem.new
    correspondence.event_id = params[:event_id]
    correspondence.comments = 'cccc' #gives error
    correspondence.user_id = params[:user_id] ##gives error

    if correspondence.save
      render :json => { :status => :ok}
    else
      render :json => { :status => :fail}
    end
  end
end

correspondence.rb

class Correspondence < ActiveRecord::Base
end

迁移文件

class CreateCorespondences < ActiveRecord::Migration
  def change
    create_table :correspondences do |t|
      t.integer :event_id
      t.integer :user_id
      t.text :comments

      t.timestamps
    end
  end
end

Answer 1

将correspondence = ActionItem.new更改为correspondence = Correspondence.new。
