我的格式如下:
class PrestataireProfilForm(forms.ModelForm):
class Meta:
model = Prestataire
fields = ["user", "name", "address", "phone", "fax", "city"]
def __init__(self, *args, **kwargs):
super(PrestataireProfilForm, self).__init__(*args, **kwargs)
self.fields['city'].widget.attrs.update({'class' : 'custom-select'})
self.fields['city'].label = ""
这是我的观点:
@login_required
def prestataire_profil(request):
prestataire = Prestataire.objects.filter(user=request.user).first()
is_prestataire = request.user.groups.filter(name='Prestataire').exists()
form = PrestataireProfilForm(request.POST or None, instance=prestataire)
if request.method == 'POST':
context = {
'profil': prestataire,
'is_prestataire': is_prestataire,
'form': form
}
if form.is_valid():
prestataire = form.save(commit=False)
prestataire.save()
context = {
'profil': prestataire,
'is_prestataire': is_prestataire
}
# return render(request, 'dashboard/prestataires/profil.html', context)
return redirect('prestataire_profil')
else:
context = {
'profil': prestataire,
'is_prestataire': is_prestataire,
'form': form
}
return render(request, 'dashboard/prestataires/profil.html', context)
这是我的html表单:

当我单击“提交”按钮时,出现以下错误:
异常类型:ValueError 异常值:视图dashboard.views.prestataire_profil没有返回HttpResponse对象。它返回None。
数据不会更改,并且调试中没有任何信息可以查看出了什么问题。您可以在视图中注意到,我评论了return渲染线。我将其更改为返回重定向,但存在相同的问题! 请帮忙!谢谢。
答案 0 :(得分:0)
沙鲁特!
我认为您的表格无效(您检查过吗?)。您已处理案件if form.is_valid()
,但如果没有,该怎么办?那你什么都不退!因此,如果在所有情况下都将重定向到prestataire_profil
,则应执行以下操作:
@login_required
def prestataire_profil(request):
[...]
if request.method == 'POST':
[...]
if form.is_valid():
[...] # do your stuff
# return redirect('prestataire_profil') <--- wrong indentation
return redirect('prestataire_profil') # <--- there, it will return something anyway
else:
[...]
return render(request, 'dashboard/prestataires/profil.html', context)
try... except... finally...
语句会更好,因为这样做不会阻止您返回None
而不是预期的HttpResponse object
。
