Question

我有一个旨在禁止用户然后将它们添加到Banned_User表格的功能。那么我可以向用户发送一封电子邮件，其中包含禁令的详细信息。但我似乎无法忍受获得禁止和保存的功能

当前回溯错误：异常类型：/ admin / api / profile /中的TypeError 例外值：禁止直接分配到多对多集的前端。请改用report_reason.set（）。

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()


    # 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.objects.create(profile=profile, report_reason=report)
        ban_record.save() 
        banned_reasons.append(report.get_report_reason_display())



    # Send the email
    subject = 'Ban'
    message = 'You have been banned for the following reasons: []' + \
    report.report_reason + banned_reasons[0] + banned_reasons[1]

    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")

BANNED_USER模型

class Banned_User(models.Model):
def __str__(self):
    return str.join(str(self.profile), str(self.report_reason.report_reason))
    #return self.profile
    #return str.join(str(self.profile), str(self.report_reason))

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

report_reason = models.ManyToManyField(
    'Report',
    #on_delete=models.PROTECT,
    blank=True,
    #null=True,
)

date_banned = models.DateField(null=True, blank=False,)

报告模型

class Report(models.Model):
def __str__(self):
    return str.join(str(self.user_reported), str(self.datetime_sent))

TOXICITY = 'Toxicity'
SPORTSMANSHIP = 'Poor sportsmanship'

REPORT_REASON_CHOICES = (
    (TOXICITY, 'Toxicity'),
    (SPORTSMANSHIP, 'Unsportsmanlike Behaviour'),
)

session = models.ForeignKey(
    'Session',
    on_delete=models.PROTECT,
    blank=False,
    null=False,
)

user_reported = models.ForeignKey(
    'Profile',
    on_delete=models.PROTECT,
    blank=False,
    null=False,
    related_name='user_reported_report',

sent_by = models.ForeignKey(
    'Profile',
    on_delete=models.PROTECT,
    blank=False,
    null=False,
    related_name='sent_by_report',
)

report_reason = models.CharField(
    max_length=255,
    choices=REPORT_REASON_CHOICES,
    default=TOXICITY,
)

datetime_sent = models.DateTimeField(auto_now_add=True,)

报告失败的原因是您尝试将外键分配给设置为要求使用add命令的多对多字段。

ban_record = Banned_User.objects.create(profile=profile, report_reason=report)

哪个不行。您需要做的是为Profile

创建banned_user模型

banned_user = profile.banned_profile.create(profile=profile)

然后你会为禁止用户添加禁令编辑

reports = banned_user.profile.user_reported_report.all()
for report in reports:
    banned_user.report_reason.add(report)

您可以在这里查看使用多对多文件。 https://docs.djangoproject.com/en/2.0/topics/db/examples/many_to_many/

麻烦禁止用户并将其添加到表中
