保存对象时，'BoundField'对象没有属性'_committed'

标签： python django django-models django-views django-database

我遇到了保存对象delivery的问题。

所以我有两个对象 - Job和Delivery。在传递job实例时，job.delivery中会发生一些更改。

一切正常 - delivery_form有效，找到job个对象，找到delivery个对象。唯一的问题是当我尝试保存delivery对象，因为它已被更改。

Exception Value:   'BoundField' object has no attribute '_committed'

注意：我已经尝试以另一种方式获取delivery：Delivery.objects.get(job=job) - 它没有改变任何内容。

我在这个问题的底部添加了错误追溯。你知道问题出在哪里吗？

这是一个观点： 

@login_required
def deliver_job(request, id): 
    deliver_form = DeliverForm(request.POST or None, request.FILES or None)

    if request.method == 'POST':
        if deliver_form.is_valid():
            job = Job.objects.get(id=id)
            notes = deliver_form.cleaned_data['notes']
            uploaded_file = deliver_form['uploaded_file']
            delivery = job.delivery
            delivery.notes_by_translator = notes
            delivery.file = uploaded_file
            delivery.status = 'delivered'
            delivery.save() # HERE IS THE PROBLEM
            return HttpResponseRedirect('/profile/' + request.user.username + '/')
        else:
            print deliver_form.errors
    context = {'deliver_form': deliver_form}

    return render(request, 'auth/jobs/deliver-job.html', context=context)

投放：

    job = models.OneToOneField(Job, related_name='delivery',on_delete=models.CASCADE)
