当我想在一个模型中保存所有表单时，我遇到了麻烦。因为形成所有我生成的东西只是先保存。所以我的帖子请求是我的输出形式。
> csrfmiddlewaretoken mL6ecbCqW8RA1oFH1AiDzv40tsRW0Esj form-0-count 1
> form-0-good 5 form-1-count 1 form-1-good 6 form-2-count 1
> form-2-good 12 form-INITIAL_FORMS 0 form-MAX_NUM_FORMS 1000
> form-MIN_NUM_FORMS 0 form-TOTAL_FORMS 3
所以我的views.py
@login_required
def index(request):
if request.user.role == '2':
shop = Shop.objects.get(owner=request.user.parent)
goods = Good.objects.filter(shop=shop, count__gt=0)
saleformset = formset_factory(SaleForm)
if request.method == 'POST':
formset = saleformset(request.POST)
for form in formset:
form.fields['good'].queryset = goods
for form in formset.forms:
a = 0
print(formset)
print(len(formset))
if form.is_valid():
print(form.is_valid())
a += 1
print(a)
new_form = form.save(commit=False)
new_form.seller = request.user
new_form.save()
good_object = Good.objects.get(pk=new_form.good.pk)
own_count = good_object.count - new_form.count
good_object = Good.objects.filter(pk=new_form.good.pk).\
update(count=own_count)
return render(request, 'all_ok.html', {'data': 'lil'})
else:
formset = saleformset()
for form in formset:
form.fields['good'].queryset = goods
return render(request, 'base_vendor.html',
{'context': goods, 'formset': formset})

答案 0 :(得分：0)
那是因为你正在使用
return render(request, 'all_ok.html', {'data': 'lil'})
作为for form in formset.forms循环的最后一条陈述。这导致视图在保存其他表单之前返回。你需要在for循环之后移动这个语句。
for form in formset.forms:
a = 0
print(formset)
print(len(formset))
if form.is_valid():
print(form.is_valid())
a += 1
print(a)
new_form = form.save(commit=False)
new_form.seller = request.user
new_form.save()
good_object = Good.objects.get(pk=new_form.good.pk)
own_count = good_object.count - new_form.count
good_object = Good.objects.filter(pk=new_form.good.pk).\
update(count=own_count)
return render(request, 'all_ok.html', {'data': 'lil'})
