Mandrill不发送

Question

我试图设置Mandrill API，以便在用户单击按钮时发送电子邮件，但我似乎无法让它发送。电子邮件将非常好地从控制台发送，所以我知道这不是一个模板的问题(设计电子邮件也发送查找)。

我认为这与我如何在控制器中设置它有关，但我找不到任何帮助，说明我应该把它放在哪里。

下面是控制器的代码：

  def attending
     @event = Event.find(params[:id])
     type = params[:type]
     if type == "attending" && @event.space != 0
        current_user.attending << @event
        @event.space = @event.space - 1
        @event.save
        AdminMailer.new_attending(@event.user, current_user)
        redirect_to :back, notice: "You've joined the group. Your number will be sent to #{@event.user.name}"

     else type == "unattending"
        current_user.attending.delete(@event)
     redirect_to :back, notice: "You've removed yourself from the group"
     end
  end

这是admin_mailer.rb

class AdminMailer < ActionMailer::Base

  require 'mandrill'

  def mandrill_client
    @mandrill_client ||= Mandrill::API.new MANDRILL_API_KEY
  end

  def new_attending(creator, user)
    template_name = "new-attending"
    template_content = []
    message = {
      to: [{email: creator.email, name: creator.name}],
      subject: "Someone wants to go riding with you!",
     merge_vars: [
       {rcpt: creator.email,
       vars: [
          {name: "CREATOR_NAME", content: creator.name},
          {name: "USER_NAME", content: user.name},
          {name: "USER_NUMBER", content: user.number}
          ]}
      ]
    }
    mandrill_client.messages.send_template template_name, template_content, message
  end

end

下面是他们在view.html.erb中点击的应该发送电子邮件的链接：

 <td><% if event.user != current_user && event.space != 0 && user_signed_in? %>
     <% unless event.attendees.include?(current_user) %>
     <%= link_to "Join", attending_event_path(event, type: "attending"), class: "btn btn-primary btn-xs", method: :put %>
     <% end %>
  <% end %></td>

任何帮助找出为什么它不发送将是伟大的！正如我说过的，当我键入：

AdminMailer.new_attending(@event, @user)

Answer 1

请替换以下代码。

AdminMailer.new_attending(@event.user, current_user)

使用

AdminMailer.new_attending(@event.user, current_user).deliver

我希望这会成功。
