Django在电子邮件模板中请求用户名，以及单击后如何移动对象以接受或拒绝文件夹

时间：2019-05-21 10:26:09

标签： django django-models django-views

我已经建立了一个视图，该视图通过模板将电子邮件发送到电子邮件地址。我想发送最初创建请求的用户名，但由于是FK，所以无法解决。

我已经尝试过通过for循环运行它并创建对象，但这只会打印出全部数据。

新视图

def accept_leave(request, id):  # accept email
    all_item = Leave.objects.get(id=id)
    context ={'all_item': all_item}

    subject = "Leave Accepted"#email subject
    email_from = "settings.EMAIL_HOST_USER"  # email from
    to_email = ['talhamurtaza@clickmail.info']  # email to

    with open("C:/Users/Bitswits 3/Desktop/Intern Work/LMS/LMS/projectfiles/templates/projectfiles/email/accept_email.txt", 'rb') as f:
        msgbody = f.read()
    msg = EmailMultiAlternatives(
        subject=subject, body=msgbody, from_email=email_from,to=to_email)
    html_template = get_template(
        "C:/Users/Bitswits 3/Desktop/Intern Work/LMS/LMS/projectfiles/templates/projectfiles/email/accept_email.html").render()
    msg.attach_alternative(html_template, "text/html")
    msg.send()

    html = render_to_string(
        "projectfiles/email/accept_email.html", {'all_item': all_item})

    return HttpResponseRedirect(html)

我希望发出请求的用户名和一些其他信息，例如他选择传递电子邮件模板并发送的休假类型。 如果我希望将一个对象从挂起状态转变为已完成状态，请问我该采取什么方法，如管理页面所示。​​

1 个答案:

答案 0 :(得分：0)

您的代码有很多问题：

  1. 您的视图accept_leave未收到申请人的姓名。您的“接受”按钮不应链接到accept_leave（GET请求），但您应为每个申请人创建一个表单，并且“接受”按钮应提交表单（作为POST请求）在网址中或输入字段中包含申请人的ID（或用户名，唯一的名称）。选中here，了解如何使用表单。

    或者，如果您确实要使用GET而不是使用表单，请更改您的accept_leave视图的URL以也具有申请人ID（/acceptemail/(?P<id>[0-9]+)$）并将ID传递给您的URL模板（{% url 'accept-page' id=obj.id %}）中的构造函数

  2. 将申请人ID传递到视图后，您将使用employee = Employee.objects.get(id=...)检索它，并且可以使用该对象填写发送电子邮件所需的内容（也可以创建电子邮件该员工的Leave对象）。

  3. 您想使用Django的模板渲染引擎来渲染模板，因此您可以将上下文变量传递到模板（例如employee）并在电子邮件模板（例如{{ employee.name }}）中使用它们。您可以使用render_to_string来做到这一点，例如：

    html = render_to_string("projectfiles/email/accept_email.html", {'employee': employee})
text = render_to_string("projectfiles/email/accept_email.txt", {'employee': employee})

    然后使用html和text发送电子邮件。
