django-admin 登录之后显示页面，表是否显示

如果是超级用户可以全部看到（如图），如果是普通用户，只能看到user与group

虽然实现了其功能，不过有些地方没搞懂，所以有些地方出了写的不好

    is_superuser = models.BooleanField(
        _('superuser status'),
        default=False,
        help_text=_(
            'Designates that this user has all permissions without '
            'explicitly assigning them.'
        ),
    )
    groups = models.ManyToManyField(
        Group,
        verbose_name=_('groups'),
        blank=True,
        help_text=_(
            'The groups this user belongs to. A user will get all permissions '
            'granted to each of their groups.'
        ),
        related_name="user_set",
        related_query_name="user",
    )
    user_permissions = models.ManyToManyField(
        Permission,
        verbose_name=_('user permissions'),
        blank=True,
        help_text=_('Specific permissions for this user.'),
        related_name="user_set",
        related_query_name="user",
    )

    class Meta:
        abstract = True

    def get_group_permissions(self, obj=None):
        """
        Returns a list of permission strings that this user has through their
        groups. This method queries all available auth backends. If an object
        is passed in, only permissions matching this object are returned.
        """
        permissions = set()
        for backend in auth.get_backends():
            if hasattr(backend, "get_group_permissions"):
                permissions.update(backend.get_group_permissions(self, obj))
        return permissions

    def get_all_permissions(self, obj=None):
        return _user_get_all_permissions(self, obj)

    def has_perm(self, perm, obj=None):
        return True

    def has_perms(self, perm_list, obj=None):
        return True

    def has_module_perms(self, app_label):
        return True

我把后面四个设置权限的全都改为True，统一在admin当中判断，在has_module_permission当中进行判断
如用户模块```
@admin.register(Custom)
class CustomAdmin(admin.ModelAdmin):
search_fields = ('name',)
ordering = ('code',)

fields = ('code', 'name','is_value','email','contact','phone','date_start','date_finish')
list_display = ('code', 'name')

判断是否为超级用户

def has_module_permission(self, request):
    if request.user.is_authenticated():
        if request.user.is_super:#is_super为自定义字段
            return True
    return False

#还有些可能会用到的
```class CustomModelAdmin(admin.ModelAdmin):
    def has_module_permission(self, request):
是否会显示model
def has_add_permission(self, request):
是否能增加信息
def has_view_permission(self, request, obj=None):
是否能查看表信息
def has_change_permission(self, request, obj=None):
是否能更改表信息```
