尽管Rails日志表明ActionMailer未发送电子邮件，但已发送

Question

我正在尝试实现actionmailer，以便在任务控制器中的show动作运行时通过电子邮件发送任务提醒。 在本地主机上运行时，我的日志指示邮件已发送，但未到达目的地。

我的development.rb：

Emailtest::Application.configure do

  config.action_mailer.delivery_method = :smtp
  config.action_mailer.smtp_settings = {
    address:              'smtp.gmail.com',
    port:                 587,
    domain:               'my_app.com',
    user_name:            ENV['xxx@gmail.com'],
    password:             ENV['xxx'],
    authentication:       'plain',
    enable_starttls_auto: true  }
  # Settings specified here will take precedence over those in config/application.rb.

  # In the development environment your application's code is reloaded on
  # every request. This slows down response time but is perfect for development
  # since you don't have to restart the web server when you make code changes.
  config.cache_classes = false

  # Do not eager load code on boot.
  config.eager_load = false

  # Show full error reports and disable caching.
  config.consider_all_requests_local       = true
  config.action_controller.perform_caching = false

  # Don't care if the mailer can't send.
  config.action_mailer.raise_delivery_errors = false

  # Print deprecation notices to the Rails logger.
  config.active_support.deprecation = :log

  # Raise an error on page load if there are pending migrations
  config.active_record.migration_error = :page_load

  # Debug mode disables concatenation and preprocessing of assets.
  # This option may cause significant delays in view rendering with a large
  # number of complex assets.
  config.assets.debug = true

  # required for heroku
  config.action_mailer.default_url_options = { :host => 'localhost:3000' }

end

我的user_mail.rb

class UserMail < ActionMailer::Base
  default from: "bri.lobdell@gmail.com"

  def task_reminder(task)
    @task = task
    @url = 'http://example.com/login'

    mail(to: @task.recipientemail, subject: "You've been sent a reminded")
  end

end

显示视图中的该行调用要传递的邮件

<% UserMail.task_reminder(@task).deliver%>

更新

我的任务索引：

<tbody>
      <% @tasks.each do |task| %>
        <% if current_user.id == task.user_id%>
          <tr>
            <td><%= task.title %></td>
            <td><%= task.description %></td>
            <td><%= task.recipientname %></td>
            <td><%= task.recipientemail %></td>
            <td><%= link_to 'Show', task %></td>
            <td><%= link_to 'Edit', edit_task_path(task) %></td>
            <td><%= link_to 'Destroy', task, method: :delete, data: { confirm: 'Are you sure?' } %></td>
            <td> <%= render 'tasks/send_mail' %></td>

          </tr>
        <%end%>

      <% end %>
    </tbody>

我的表格：_send_mail.html.erb

<%= form_tag("/tasks/send_mail", method: "post", url: send_mail_path) do  %>
<%= hidden_field_tag :task_id, 'task.id' %>
<%= submit_tag "Remind" %>
<% end %>

任务#send_mail

def send_mail
    @task = Task.find(params[:id])
    UserMail.task_reminder(@task).deliver
    redirect_to :back
  end

Answer 1

要在控制器中调用该代码行，可以创建一个指向控制器中某个动作的表单，该动作将具有以下内容：

def send_mail
@task = Task.find(params[:task_id])
UserMail.task_reminder(@task).deliver
redirect_to :back
end

您还需要在路由文件中输入该控制器，如下所示：

post "tasks/send_mail", :to => "tasks#send_mail", :as => "send_mail"

这就是您的表格（非常简单），那里只有一个按钮。 您可以在页面加载时触发该表单：

<%= form_tag("/tasks/send_mail", method: "post", url: send_mail_path) do  %>
<%= hidden_field_tag :task_id, "#{@task.id}" %>
<%= submit_tag "Submit" %>
<% end %>

希望这可以帮助！

尝试将其添加到send_mail方法的顶部：

if(params.has_key?(:task_id)
redirect_to "/"
end

如果它重定向您，则参数将被传递，否则，我们将遇到问题;）
