Ruby on rails 3 Rails 3 ActionMailer模型属性

我想在用户填空后将信息发送到我的邮件中。但是我不能以HTML格式将用户的模型属性发送到我的邮件地址

class DemandMailer < ActionMailer::Base
  default from: "mail@mail.com"

  def demand_call(demand)
      mail(:to => "mymail@mail.com" , :subject => "user registered") 
  end
end

如何解决它？

您应该在方法中定义实例变量

  class DemandMailer < ActionMailer::Base
    default from: "mail@mail.com"

    def demand_call(demand)
      @demand = demand
      mail(:to => "mymail@mail.com" , :subject => "user registered") 
    end
  end

类DemandMailer）mymail@mail.com“，：主题=>“用户已注册”） 终止 终止 在内部视图中可以使用它

the user name is <%= @demand.name %>

用户名是

  class DemandMailer < ActionMailer::Base
    default from: "mail@mail.com"

    def demand_call(demand)
      @demand = demand
      mail(:to => "mymail@mail.com" , :subject => "user registered") 
    end
  end

the user name is <%= @demand.name %>
