我有一个表单,我不会将其作为HTML页面的一部分呈现,但验证输入:
class milestone_form(forms.Form):
name = forms.CharField(required=True)
completion = forms.IntegerField(initial=0, required=False)
due_date = forms.DateField(required=True,input_formats={'%d.%m.%Y'})
phase = forms.IntegerField(required=True)
这个完成位导致了很多问题:
form = milestone_form(request.POST)
form.is_valid()#will return False on empty completion
我尝试覆盖form的clean(),使其为空时完成= 0:
def clean(self):
cleaned_data = self.cleaned_data
if cleaned_data.get('completion') is None:
cleaned_data['completion'] = 0
return cleaned_data
然而,它没有帮助。还有其他我想念的东西吗?
答案 0 :(得分:3)
这可能是我为空字段返回一个整数的方法,错误检查:
from django.forms import ValidationError
def clean_completion(self):
if self.cleaned_data.get('completion'):
try:
return int(self.cleaned_data['completion'].strip())
except ValueError:
raise ValidationError("Invalid number")
return 0
