Question

您好我添加了自定义验证。它抛出一个TypeError，表示issubclass（）arg 1必须是一个类。我在admin.py中的代码是

class AppraisalScheduleAdmin(admin.ModelAdmin):
    exclude = ['intUpdatedBy']
    form = 'tbmstappraisalschedForm'

        def save_model(self, request, obj, form, change):
            obj.intUpdatedBy = request.user.id
            obj.save()

class tbmstappraisalschedForm(forms.ModelForm):

     def clean(self):
          """ 
          Override the default clean method to check whether this course has been already inputted.
          """    
          cleaned_data = super(tbmstappraisalschedForm, self).clean()
          depart_id = cleaned_data.get('intDeptID')
          fromdate = cleaned_data.get('sdtFromDate')
          todate = cleaned_data.get('todate')
          matching_records = tbmstappraisalsched.objects.filter(intDeptID=depart_id)
          if self.instance:
              matching_records.exclude(pk=self.instance.pk)
          if matching_records.exists():
              msg = "The slot for selected department and selected dates exists" % name
              raise ValidationError(msg)
          else:
              return self.cleaned_data
    class Meta:
        model = tbmstappraisalsched

追溯是

回溯： get_response中的文件“C：\ Python27 \ lib \ site-packages \ django \ core \ handlers \ base.py” 103. resolver_match = resolver.resolve（request.path_info）解析文件“C：\ Python27 \ lib \ site-packages \ django \ core \ urlresolvers.py” 319.对于self.url_patterns中的模式： url_patterns中的文件“C：\ Python27 \ lib \ site-packages \ django \ core \ urlresolvers.py” 347. patterns = getattr（self.urlconf_module，“urlpatterns”，self.urlconf_module） urlconf_module中的文件“C：\ Python27 \ lib \ site-packages \ django \ core \ urlresolvers.py” 342. self._urlconf_module = import_module（self.urlconf_name） import_module中的文件“C：\ Python27 \ lib \ site-packages \ django \ utils \ importlib.py” 35. 导入（姓名）文件“C：\ pythonprgs \ opas \ opas \ urls.py”中 5. admin.autodiscover（）自动发现中的文件“C：\ Python27 \ lib \ site-packages \ django \ contrib \ admin__init __。py” 29. import_module（'％s.admin'％app） import_module中的文件“C：\ Python27 \ lib \ site-packages \ django \ utils \ importlib.py” 35. 导入（姓名）文件“C：\ pythonprgs \ opas \ schdeules \ admin.py”中 60. admin.site.register（tbmstappraisalsched，AppraisalScheduleAdmin）在寄存器中输入“C：\ Python27 \ lib \ site-packages \ django \ contrib \ admin \ sites.py” 98. validate（admin_class，model）在验证中文件“C：\ Python27 \ lib \ site-packages \ django \ contrib \ admin \ validation.py” 25. validate_base（cls，model） validate_base中的文件“C：\ Python27 \ lib \ site-packages \ django \ contrib \ admin \ validation.py” 317.如果hasattr（cls，'form'）而不是issubclass（cls.form，BaseModelForm）：

异常类型：/ admin / schdeules / tbmstappraisalsched / add /中的TypeError 异常值：issubclass（）arg 1必须是类

请参阅以下admin.py代码

    from .forms import tbmstappraisalschedForm 
    class AppraisalScheduleAdmin(admin.ModelAdmin):
        exclude = ['intUpdatedBy']
    #    form = 'tbmstappraisalschedForm'  you can not pass a string  here .
         form = tbmstappraisalschedForm     #do like this

        def save_model(self, request, obj, form, change):
            obj.intUpdatedBy = request.user.id
            obj.save()
