我尝试过的其他类似问题的解决方案：

问题是FilteredSelectMultiple只显示了一半：

我尝试过的事情：

同步数据库
检查 jQuery 是否正在运行
检查了 jQuery 导入冲突，但我是新手它，所以我不确定。

【解决方案1】：

使用 django 2.2，我可以通过将其放入我的

中来解决这个问题

urls.py

urlpatterns = [
...
...
/* all your urls */

re_path(r'^jsi18n/$', JavaScriptCatalog.as_view(), name='javascript-catalog')
]

模板底部

<script type="text/javascript" src="{% url 'javascript-catalog' %}"></script>

forms.py

class ManageUserPermissionsForm(forms.ModelForm):
    class Meta:
        model = User
        fields = ['permissions']

    permissions = forms.ModelMultipleChoiceField(queryset=Permission.objects.all(),required=True,
                      widget=FilteredSelectMultiple('User Permissions',is_stacked=False))

    class Media:
        css = {'all': ('/static/admin/css/widgets.css',), }

views.py（你可以忽略 mixin 和 slug_field 和 slug_url_kwarg 所需的权限

class ManageUserPermissionsView(PermissionRequiredMixin, UpdateView):
    permission_required = 'manage_user'
    model = User
    form_class = ManageUserPermissionsForm
    template_name = 'manage_permissions.html'
    slug_field = 'uuid'
    slug_url_kwarg = 'uuid'

我专门为管理用户权限而做这个，但是查询集可以是任何你想要的
