Django Check and set permissions for a user group

I have a usergroup called baseusers with a set of permissions I have added via admin. If baseusers doesn't exist I want to create it and set the same permissions it has now. I can create the group but how do I find out the permissions from shell and then add them in my code? For example two of the permissions are named can_fm_list and can_fm_add. Application is called fileman. But do I need to use id:s instead? Here is the code I would like the permissions to be set.

userprofile/views.py

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开发者_运维知识库 = 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()

Take a look at this blog post: Django: Using The Permission System

Adapted to your example:

can_fm_list = Permission.objects.get(name='can_fm_list')
newgroup.permissions.add(can_fm_list)

For others who are looking for adding multiple permissions at once,

permissions_list = Permission.objects.all()
new_group.permissions.set(permissions_list)

list of permissions add to a new group :-

group_name = request.POST.get('group_name')
permissions_list = request.POST.getlist('permission')
permissions_list_id = []
new_group = Group.objects.create(name=group_name)

for perm in permissions_list:
    p = Permission.objects.get(name=perm)
    permissions_list_id.append(p.id)

new_group.permissions.set(permissions_list_id)
