Question

好吧，我有一个字段类型FileField，当我尝试删除它的内容时，返回给我这个错误信息：'bool'对象没有属性'_committed'` 要正常上传，只有在我尝试删除已发送的文件时才会出现问题。

我的观点：

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

这种回应来得很晚，但可能会帮助其他人，因为今天我遇到了类似的问题。我在views.py的同一行上收到了相同的错误消息，每当我想保存一个空的ImageField时都会发生。

我的观点：

def recipe_new(request):
if request.method == 'POST':
    form = RecipeForm(request.POST, request.FILES or None)
    if form.is_valid():
        recipe = form.save(commit=False)
        recipe.author = request.user
        recipe.published_date = timezone.now()
        recipe.save()  #Error here.
        return redirect('recipe_detail', pk=recipe.pk)
else:
    form = RecipeForm()
return render(request, 'blog/recipe_edit.html', {'form': form})

我的表单：

class RecipeForm(forms.ModelForm):

class Meta:
    model = Recipe
    fields = ('title', 'image', 'is_vegan', 'is_veggie', 'cuisine',
              'contained_allergen', 'instruction')

我的模特：

class Recipe(models.Model):
    author = models.ForeignKey(
        settings.AUTH_USER_MODEL, on_delete=models.CASCADE)
    title = models.CharField(max_length=200)
    image = models.ImageField(upload_to="images", default=True)
    is_vegan = models.BooleanField("Vegan", default=False)
    is_veggie = models.BooleanField("Vegetarisch", default=False)
    etc.

事实证明ImageField中的参数default=True引起了问题。删除后，错误消息消失了。

Answer 2

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/">

Django'bool'对象没有'_committed'属性
