我已经看到这个问题与寻求帮助创建新闻通讯系统的人们有很多关系.
我有一个使用roadie gem的简报邮件设置.我需要帮助来弄清楚如何设置时事通讯的订户部分.我一直在从邮件客户端手工做通讯,所以我有大约300个订阅者.
有人可以帮我设置代码,以便所有注册用户自动订阅时事通讯,我可以将我的300个电子邮件订阅者导入列表.还应该有取消订阅链接.援助对我和其他许多人都非常有帮助.
newsletter_mailer.rb:
class NewsletterMailer < ActionMailer::Base
default from: "from@example.com"
def weekly(email)
@newsletter = newsletter
@recipient = recipient
mail to: email, subject: "New Dates Weekly"
end
通讯控制器:
def send
@newsletter = Newsletter.find(:params['id'])
@recipients = Recipient.all
@recipients.each do |recipient|
Newsletter.newsletter_email(recipient, @newsletter).deliver
end
end
用户控制器:
def settings
@user = User.find(params[:id])
end
def new
@user = User.new
end
def profile
@profile = User.profile
@user = User.find(params[:id])
end
def create
@user = User.new(user_params)
if @user.save
UserMailer.registration_confirmation(@user).deliver
session[:user_id] = @user.id
redirect_to root_url, notice: "Thank you for signing up!"
else
render "new"
end
end
def show
@user = User.find(params[:id])
end
def edit
@user = User.find(params[:id])
end
最佳答案 听起来你需要User和Recipient之间的一对一关系:
class User < ActiveRecord::Base
has_one :recipient
...
end
class Recipient < ActiveRecord::Base
belongs_to :user
...
end
然后在您的注册过程中,您只需要创建用户的收件人:
def create
@user = User.new(user_params)
if @user.save
...
@user.create_recipient(:email => @user.email)
...
else
render "new"
end
end
