我只是在UsersController#new
:
def new
@user = User.new
@user.next_billing_cycle = Date.today
respond_to do |format|
format.html # new.html.erb
format.json { render json: @user }
end
end
在我的开发环境中完美运行。我的用户模型有attr_accessible :next_billing_cycle
,因此它也有相应的date_select
字段集:
class User < ActiveRecord::Base
attr_accessible :name, :next_billing_cycle
end
但是,在Heroku中,我收到此错误:

更新 :我应该明确表示,已经运行heroku rake db:migrate
。
答案 0 :(得分:0)
您的意思是使用attr_accessor
吗?或next_billing_cycle
是DB中的一列?
