I want to make sure users fill all the fields before they are
redirected to the next page. And if they don’t fill the fields it
should raise an error telling them to fill the fields before they
proceed. So to do that, I wrote the codes below. But the problem I’m
facing is that when I didn’t fill the fields, it took me to the next
page, instead of it to return me to the same page, and it didn’t raise
any error.
How can I make it validate those fields before taking users to the
next page?
Model:
from django.core.exceptions import ValidationError
class Memb(models.Model):
slug=models.CharField(max_length=100)
member=models.CharField(max_length=100)
def __unicode__(self):
return self.member, self.slug
def clean_slug(self):
data=self.cleaned_data['slug']
if "Testy" not in data:
raise ValidationError("Enter the correct name for this
field")
class MembForm(ModelForm):
class Meta:
model=Memb
fields=('slug','member')
Views:
def my_memb(request):
if request.method=="POST":
form=MembForm(request.POST)
if form.is_valid():
data=form.cleaned_data
form.save()
return HttpResponseRedirect('/good/')
else:
form=MembForm()
return render_to_response('member.html',{'MembForm':MembForm},
context_instance=RequestContext(request))
Template:
{% block content %}
<form action="" method="POST">
{{MembForm.as_p}}
<input type="submit" value="Add"/>
</form>
{% endblock %}
