Question

我一直在研究我的Django项目。我使用自定义表单（一个名为Form的类），我有一个名为 Restricted_Form 的类。此类的要点是管理员用户（“员工状态”用户“）具有限制哪些用户或组可以访问表单/提交填写表单的选项：

#....models.py:
from django.contrib.auth.models import User, Group

class Restricted_Form(models.Model):
    Form = models.ForeignKey('forms.Form')
    Authorized_Users = models.ManyToManyField(User, blank=True)
    Authorized_Groups = models.ManyToManyField(Group, blank=True)
    user = models.ForeignKey(User, blank=True, null=True, related_name="restriction_owner")

“表格”本身有：

user = models.ForeignKey(User, blank=True, null=True)
#this is always the user who created it

我的问题是限制非超级用户管理员可以执行的操作。他们应该只能创建 Restricted_Form 对象，包括他们自己创建的表单。实际上，当他们创建Restricted_Form时，只有他们自己创建的“表单”应该在下拉菜单中显示为选择选项。这是我现在的相关管理类：

#...admin.py
class RestrictedFormAdmin(admin.ModelAdmin): 
    fieldsets = [
    (None, {"fields": ("Form", "Authorized_Users", "Authorized_Groups")}),]
    def save_model(self, request, obj, form, change):
        if getattr(obj, 'user', None) is None:  
            obj.user = request.user
        obj.save()
    def get_queryset(self, request):
        qs = super(RestrictedFormAdmin, self).get_queryset(request)
        if request.user.is_superuser:
            return qs
        return qs.filter(user=request.user)
    def has_change_permission(self, request, obj=None):
        if not obj:
            return True 
        return obj.user == request.user or request.user.is_superuser

admin.site.register(Restricted_Form, RestrictedFormAdmin)

非常感谢帮助。

您可以尝试这样的事情：

class RestrictedFormAdmin(admin.ModelAdmin):
    def render_change_form(self, request, context, *args, **kwargs):
        context['adminform'].form.fields['Form'].queryset = Form.objects.filter(user=request.user)
        return super(RestrictedFormAdmin, self).render_change_form(request, context, args, kwargs)

Django Admin-限制ForeignKey Field的选择
