如何将禁止用户添加到表中，并将详细信息发送到 Django Admin 中的用户电子邮件

Question

我有一个简单的禁止功能，将用户活动设置为假，还有一个基本的电子邮件功能来发送电子邮件。我正在使用的表是User,Profile,Report & Banned_User 表。

我期待：

1. 将用户Profile,Reason_reported 从Report 表和datetime 添加到 Banned_User 表一旦被禁止。
2. 将这些详细信息发送到用户电子邮件

目前我正在收到一个 'Attribute Error at /admin/api/profile/: WSGIRequest' object has no attribute 'report'' 不知道如何去做这两件事。

def banning_users(self, request, queryset):

for obj in queryset:
    if hasattr(obj, 'user'):
        # This object is a Profile, so lookup the user
        obj = obj.user
    obj.is_active = False

    #email function
    banned_user = Banned_User.objects.create(profile=request.user.profile, report_reasons=request.report.report_reason)
    banned_user.save()
    #Sends ban email to user,does not send through the variables yet
    subject = 'Ban'
    message =   'You have been banned'
    email_from = settings.EMAIL_HOST_USER
    recipient_list = [obj.email]
    send_mail( subject, message,email_from, recipient_list )
    obj.save()


self.message_user(request, "User is banned and Email has been sent")

表格如下：

Answer 1

我期待：

1. 将用户个人资料、Reason_reported from Report 表和他们被禁止的日期时间添加到 Banned_User 表中。

2. 将这些详细信息发送到用户电子邮件

将您的问题分解为实际问题，步骤是首先创建封禁报告，然后添加用户，最后发送电子邮件。

错误消息告诉您request 对象没有report 属性，这是有道理的，因为它与用户相关联的报告，而不是请求。

def banning_users(self, request, queryset):

    for obj in queryset:
        if hasattr(obj, 'user'):
            # This object is a Profile, so lookup the user
            profile = obj
            user = obj.user
        user.is_active = False

        # Get the report(s) for this user
        user_reports = Report.objects.filter(user_reported=profile)

        # Go through each report, in case there are multiples,
        # add a record in the ban table

        banned_reasons = []

        for report in user_reports:
            ban_record = Banned_User.create(profile=profile, report_reason=report, date_banned=datetime.datetime.today())
            banned_reasons.append(report.get_report_reason_display())

        # Send the email
        subject = 'Ban'
        message = 'You have been banned for the following reasons: {}'
        message.format(','.join(banned_reasons))
        email_from = settings.EMAIL_HOST_USER
        recipient_list = [user.email]
        send_mail( subject, message,email_from, recipient_list)

    self.message_user(request, "User is banned and Email has been sent")

Answer 2

问题来自这一行：

banned_user = Banned_User.objects.create(profile=request.user.profile, 
           report_reasons=request.report.report_reason)

您正在尝试访问请求中的报告，而请求没有此属性。

我建议您将ForeignKey 更改为ManyToManyField，因为一个用户可以有多个报告。

class Banned_User(models.Model):
    def __str__(self):
        return self.user.get_username

    profile = models.ForeignKey('Profile',on_delete=models.PROTECT,
         blank=False, null=False, related_name='banned_profile',)

    report_reasons = models.ManyToManyField('Report',blank=True)

所以你会得到这个：

if hasattr(obj, 'user'):
    # This object is a Profile, so lookup the user
    obj = obj.user
obj.is_active = False

# email function
banned_user = Banned_User.objects.create(profile=request.user.profile)
banned_user.report_reasons.add(request.user.profile.user_reported_report.all())
# rest of code 

Answer 3

这是最终让它工作的代码 :) 感谢大家的帮助

def banning_users(self, request, queryset):

    for obj in queryset:
        if hasattr(obj, 'user'):
            # This object is a Profile, so lookup the user
            profile = obj
            user = obj.user
        user.is_active = False
        user.save()

        banned_reasons = []

    
        banned_user = profile.banned_profile.create(profile=profile)
        reports = banned_user.profile.user_reported_report.all()
        banned_user.save()
        for report in reports:
            banned_user.report_reason.add(report)
        
        # Send the email
        subject = 'Ban'
        message = 'You have been banned for the following reasons: []'
        email_from = settings.EMAIL_HOST_USER
        recipient_list = [user.email]
        send_mail( subject, message,email_from, recipient_list)

    self.message_user(request, "User is banned and Email has been sent")
