这是我得到的错误:
ContactPostalcardsController#skip (NoMethodError) "undefined method `status=' for #<ContactPostalcard:0x2b21433d64b0>"
这是调用它的代码,并尝试为ContactPostalcard(模型)的status属性赋值:
def skip
@contact_postalcard = ContactPostalcard.new(params[:contact_postalcard])
@contact_postalcard.contact_id = params[:contact_id]
@contact_postalcard.postalcard_id = params[:postalcard_id]
@contact_postalcard.status = "skipped"
@contact_postalcard.date_sent = Date.today
@contact_postalcard.date_created = Date.today
if @contact_postalcard.save
render :text => 'This email was skipped!'
end
end
这是推荐的模型。请注意,“annotate”输出将状态显示为属性:
class ContactPostalcard < ActiveRecord::Base
attr_accessible :title, :contact_id, :postal_id, :postalcard_id, :message, :campaign_id, :date_sent, :status
belongs_to :contact
belongs_to :postalcard
alias_attribute :body, :message
alias_attribute :subject, :title
named_scope :nosugar, :conditions => { :sugarcrm => false }
def company_name
contact = Contact.find_by_id(self.contact_id)
return contact.company_name
end
def asset
Postalcard.find_by_id(self.postalcard_id)
end
def asset_class
Postalcard.find_by_id(self.postalcard_id).class.name
end
end

我不清楚为什么我会继续得到'未定义的方法' - 我已经添加了status属性(之前已经丢失但是使用了迁移然后进行了raked),所以需要一些帮助......谢谢。
答案 0 :(得分:1)
您是否在运行迁移后重新启动了Rails应用程序?如果您正在生产模式下运行,Rails会缓存您的类,直到您重新启动它,并且由于状态在迁移之前不是属性,因此Rails不会为其添加访问器方法,这可以解释为什么status=
未定义。
