Question

我在我的Tags表中添加了一个新的属性列，在本地它运行正常。但是在heroku中，即使我已经完成了heroku run rake db:migrate并且创建了新列，但在创建新标记时它会给我一个错误。

ActionView::Template::Error (undefined method `price_type' for #<Tag:0x007fc3180e9448>):

为什么这会在升级而非开发中发生？

编辑：

迁移文件

class AddPriceTypetoTags < ActiveRecord::Migration
  def change
    add_column :tags, :price_type, :integer
    add_column :tags, :max_price, :integer
    rename_column :tags, :price, :min_price
  end
end

我的heroku记录

heroku run rake db:migrate --remote staging
Running `rake db:migrate` attached to terminal... up, run.7489
