django - Django 在电子邮件模板中请求用户名以及单击后如何将对象移动到接受或拒绝文件夹

Question

我制作了一个视图，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的名称，但我无法理解它，因为它是 FK。

我尝试通过 for 循环运行它并创建对象，但这只是打印全部数据。

视图.py

def accept_leave(request): #accept email
    all_item = Leave.objects.all()
    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

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.send()

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

    return HttpResponseRedirect(html)

我想要请求用户的姓名和其他一些信息，例如他选择通过电子邮件模板传递并发送的休假类型。如果我希望一个对象从其挂起状态移动到完成状态，如管理页面所示，您能否指导我采取什么方法。

Answer 1

你的代码有很多问题：

1. 你的观点accept_leave没有收到申请人的名字。您的“接受”按钮不应是指向accept_leave（GET 请求）的链接，但您应该为每个申请人创建一个表单，并且“接受”按钮应提交带有申请人 ID 的表单（作为 POST 请求）（或用户名，唯一的东西）在 URL 中或作为输入字段。在这里查看以了解如何使用表单。

   或者，如果您真的想使用 GET 而不是使用表单，请将accept_leave视图的 URL 更改为也具有申请人 id ( /acceptemail/(?P<id>[0-9]+)$) 并将 id 传递给模板 ( {% url 'accept-page' id=obj.id %})中的 url 构造函数

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

3. 您想使用 Django 的模板渲染引擎来渲染您的模板，因此您可以将上下文变量传递给您的模板（例如employee）并在您的电子邮件模板中使用它们（例如{{ employee.name }}）。您可以使用 来做到这一点render_to_string，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并text发送电子邮件。
