我有以下型号,
class Exam
has_many :registrations
end
class Registration
belongs_to: user
belongs_to: lesson
end
class Lesson
has_many :exam_registrations
belongs_to :user
end
class User
has_many :registrations, :through => lessons
end
我正在尝试设置一个自动发送的电子邮件,每当更新考试时,都会向每个已注册的用户发送电子邮件。我已经设置了动作邮件并为其他非嵌套资源工作,但这个特殊情况让我在过去的几天里难以接受。
mailer.rb
def inform_exam_venue(user, student, lesson, exam_registration, exam)
@user = user
@student = student
@lesson = lesson
@exam_registration = exam_registration
@exam = exam
mail(:to => "#{student.name} <#{student.email}>", :subject => "Exam registration update")
end
exams_controller.rb
def update
@exam = Exam.find(params[:id])
@exam_registration = @exam.exam_registrations.find(params[:id])
@lesson = @exam_registration.lesson
@user = User.where("id =? ", @exam_registration.user_id).first
@student = Student.where("id =? ", @exam_registration.student_id).first
respond_to do |format|
if @exam.update_attributes(params[:exam])
Mailer.inform_exam_update(@user, @student, @lesson, @exam_registration, @exam).deliver
format.html { redirect_to @exam, notice: 'Exam was successfully updated.' }
else
format.html { render action: "edit" }
end
end
end
我的控制器代码显然是错误的,但我似乎无法找到有关如何设置它的任何说明。请帮忙。
答案 0 :(得分:1)
我在你的代码中发现的唯一错误是你在控制器中使用
Mailer.inform_exam_update
而不是
Mailer.inform_exam_venue
因此,您需要将 _update 更改为 _venue
