python之Django 'bool' 对象没有属性 '_committed'

好吧，我有一个字段类型 FileField，当我尝试删除它的内容时，会返回此错误消息:“bool”对象没有属性“_committed”` 上传工作正常，问题仅出现在我尝试删除已发送的文件时。

我的看法:

try: 
    profile = request.user.get_profile() 
    company = profile.company 
except ObjectDoesNotExist: 
    raise Http404  
 
if request.method == 'POST': 
   data = request.POST 
   profile_form = EditUserProfileForm(data=data) 
   company_form = EditCompanyForm(data=data, files=request.FILES) 
 
  if profile_form.is_valid() and company_form.is_valid(): 
     profile_form.save(profile) 
     company_form.save(company) 
     messages.info(request, 'Dados atualizados com sucesso.') 
     return HttpResponseRedirect('') 
 else: 
    profile_form.save(profile) 
    company_form.save(company)  #Error here. 
    messages.info(request, 'Dados atualizados com sucesso.') 
    return HttpResponseRedirect('')

编辑:EditCompanyForm:

class EditCompanyForm(CompanyForm): 
 
    class Meta: 
        model = accounts.models.Company 
        exclude = ('verified', 'rating') 
 
 
    def save(self, company): 
        company.insurance_policy = self.cleaned_data['insurance_policy'] 
        company.save() 
        return company 

请您参考如下方法:

我有同样的错误，原因是我没有在我的表单中设置 enctype， <form enctype="multipart/form-data" method="post" action="/foo/">
