我有以下形式:Django的自定義窗體是無效的,由於形式初始化
class PlayerAchievementForm(forms.ModelForm):
class Meta:
model = PlayerAchievement
fields = ('achievement',)
def __init__(self, *args, **kwargs):
super(PlayerAchievementForm, self).__init__(**kwargs)
self.fields['achievement'].queryset = Achievement.objects.filter(input_type=0)
我在一個視圖下執行:
def points(request, action, target=None):
if request.method == 'POST':
if target == 'player':
form = PlayerAchievementForm(request.POST)
print form.errors
if form.is_valid():
print 'valid'
elif:
print 'invalid'
在提交時,這個打印無效。
如果我拿出這條線的形式:
def __init__(self, *args, **kwargs):
super(PlayerAchievementForm, self).__init__(**kwargs)
self.fields['achievement'].queryset = Achievement.objects.filter(input_type=0)
然後將其保存沒有問題。 init有什麼問題?
