为什么没有调用我的自定义验证？
|
我有这个模型和模型形式：
class Comment(models.Model):
text = models.CharField(max_length=100)
def clean_text(self):
print \"called Comment\"
if len(self.text) <= 5:
raise ValidationError(\"must have 5 chars at least\")
class CommentForm(ModelForm):
class Meta:
model = Comment
def clean_text(self):
print \"called CommentForm\"
if len(self.text) <= 5:
raise ValidationError(\"must have 5 chars at least\")
CommentFormSet = modelformset_factory(model=Comment,form=CommentForm,extra=3)
if request.method == \"POST\":
formset = CommentFormSet(request.POST)
if formset.is_valid():
print \"VALID FORM\"
else:
formset = CommentFormSet()
return render_to_response(\"first.html\",{\"formset\":formset},context_instance=RequestContext(request))
<form action=\"first\" method=\"post\">
{% csrf_token %}
{% for dict in formset.errors %}
{% for error in dict.values %}
{{ error }}
{% endfor %}
{% endfor %}
<table>
{{ formset }}
</table>
<input type=\"submit\" value=\"Create\"/>
</form>
def validate_min(val):
print \"validator called\"
if len(val) <= 5:
raise ValidationError(\"At least 5 characters should be provided\")
class Comment(models.Model):
text = models.CharField(max_length=100,validators=[validate_min])
没有找到相关结果

def validate_min_length(value): if len(value) <= 5: raise ValidationError(\"must have 5 chars at least\") class Comment(models.Model): text = models.CharField(max_length=100, validators=[validate_min_length])创建空表格。这意味着它们将通过验证。覆盖其中任何一个，您将获得所需的内容。
