html - 'ManagementForm 数据丢失或被篡改
问题描述
我在我的 django 应用程序中使用以下代码,如果我按原样使用它可以正常工作,但是当我将基础扩展到以下 html 时,它会引发以下错误:
django.core.exceptions.ValidationError: ['ManagementForm 数据丢失或被篡改']

});
</script>
</body>
</html>
我要添加的代码:
{% extends 'base.html' %}
{% block content %}
..The above code
{% endblock %}
为什么会这样?
表格.py
class PlayerForm(forms.ModelForm):
class Meta:
model = Player
fields = '__all__'
PlayerFormset= formset_factory(PlayerForm)
class TeamForm(forms.ModelForm):
player= PlayerFormset()
class Meta:
model = Team
fields = '__all__'
exclude = ["player"]
视图.py
def post(request):
if request.POST:
form = TeamForm(request.POST)
form.player_instances = PlayerFormset(request.POST)
if form.is_valid():
team= Team()
team.tname= form.cleaned_data['tname']
team.save()
if form.player_instances.cleaned_data is not None:
for item in form.player_instances.cleaned_data:
player = Player()
player.pname= item['pname']
player.hscore= item['hscore']
player.age= item['age']
player.save()
team.player.add(player)
team.save()
else:
form = TeamForm()
return render(request, 'packsapp/employee/new.html', {'form':form})
