我有一个名为baseusers的用户组，我通过管理员添加了一组权限。如果baseusers不存在，我想创建它并设置与它现在相同的权限。我可以创建该组，但如何从shell中找到权限，然后将它们添加到代码中？例如，其中两个权限名为can_fm_list和can_fm_add。应用程序名为fileman。但是我需要使用id：s来代替吗？下面是我想设置权限的代码。
第一个月

from fileman.models import Setting (Has the permissions)
from fileman.models import Newuserpath
from django.contrib.auth.models import Group

def register(request):

...

            if Group.objects.count() > 0:
            newuser.groups.add(1)
            else:
            newgroup = Group(name='baseusers')
            newgroup.save()
            newuser.groups.add(1)

fileman/models.py

class Setting(models.Model):
    owner = AutoForeignKey(User, unique=True, related_name='fileman_Setting')
    root = models.CharField(max_length=250, null=True)
    home = models.CharField(max_length=250, null=True)
    buffer = models.TextField(blank=True)
    class Meta:
        permissions = (
            ("can_fm_list", _("Can look files list")),
            ("can_fm_add", _("Can upload files")),
            ("can_fm_rename", _("Can rename files")),
            ("can_fm_del", _("Can move files to basket")),
            ("can_fm_destruct", _("Can delete files")),
        )
    def __unicode__(self):
        return unicode(self.owner)
    def __init__(self, *args, **kwargs):
        super(Setting, self).__init__(*args, **kwargs)
        if not self.root:
            self.root = None
            self.home = None
    def writeBuffer(self, data):
        self.buffer = data
        self.save()
