在用户填充灯后,我想向我的邮件提供信息。 但是,我可以以超文本格式将用户模型属性寄给我的邮件地址。
class DemandMailer < ActionMailer::Base
default from: "[email protected]"
def demand_call(demand)
mail(:to => "[email protected]" , :subject => "user registered")
end
end
和需求——召唤.html.erb类似
the user name is <%= @demand.name %>
但错误
ActionView::Template::Error (undefined method `name for nil:NilClass):
我如何解决这一问题?
你们应当界定在方法上的差异
class DemandMailer < ActionMailer::Base
default from: "[email protected]"
def demand_call(demand)
@demand = demand
mail(:to => "[email protected]" , :subject => "user registered")
end
end
than can use it inside view
the user name is <%= @demand.name %>
