在forms.ModelForm使用request.POST

class ThisForm(forms.ModelForm):
class Meta:
model = ThisModel
fields = '__all__'

def __init__(self, *args, **kwargs):
self.iscommit = False
if len(args) > 0:
if args[0].get('_commit') is not None:
self.iscommit = True
super(MatchInitForm, self).__init__(*args, **kwargs)

def clean(self):
if self.iscommit:
# 数据校验
raise forms.ValidationError(
"数据校验。"
)

class ModelForm(six.with_metaclass(ModelFormMetaclass, BaseModelForm)):
pass

def __init__(self, data=None, files=None, auto_id='id_%s', prefix=None,
initial=None, error_class=ErrorList, label_suffix=None,
empty_permitted=False, instance=None):
# 其他省略
pass

form = ThisForm(request.POST)
# 即data = request.POST
