ModelForm not getting saved on server - django

Question

I have a view that uses a modelform to create circles. This works perfectly fine on localhost but on server, the data is not getting created since "save" method is not working.
ModelForm:
class CircleForm(forms.ModelForm):
class Meta:
model = Circles
fields = ('heading','description',)
#exclude = ['current_status', 'progress', 'Owner', 'team_tag', 'exceptional_tag','Team']
def __init__(self, *args, **kwargs):
super(CircleForm, self).__init__(*args, **kwargs)
for name, field in self.fields.items():
if field.widget.attrs.has_key('class'):
field.widget.attrs['class'] += ' text'
else:
field.widget.attrs.update({'class':'text'})
Model:
class Circles(CommonInfo):
CURRENT_STATUS = (('P', 'pending'),
('C', 'complete'),
('ED', 'exceeded deadline'),
('I', 'incomplete'))
Owner = models.ForeignKey(OrganisationUser, related_name="owner_name", blank=True, null=True)
Team = models.TextField(default='', blank=True, null=True)
heading = models.CharField(default='', max_length=100)
description = models.CharField(default='', max_length=250)
progress = models.PositiveIntegerField(default=0, null=True, blank=True)
deadline = models.DateField(null=True,blank=True)
current_status = models.CharField(choices=CURRENT_STATUS, max_length=2, default='P')
team_tag = models.ForeignKey("certificates.Tag", related_name="team_tag_given", blank=True, null=True)
exceptional_tag = models.ForeignKey("certificates.Tag", related_name="exeptioml_tag_given", blank=True, null= True)
View:
def non_ajax_post(self, request, *args, **kwargs):
circle_form = CircleForm(request.POST)
if circle_form.is_valid():
try:
circle = circle_form.save(commit=False)
circle.Owner = request.user.organisation_user
#circle.Team = json.dumps(request.POST.get('hidemps_id'))
team_tag = Tag.objects.get(pk = request.POST.get('team_tag_id'))
exceptional_tag = Tag.objects.get(pk = request.POST.get('exceptional_tag_id'))
circle.team_tag = team_tag
circle.exceptional_tag = exceptional_tag
deadline = string_time_to_datetime(request.POST.get('deadline'), type_of_date='m/d/y')
if deadline < datetime.now():
request.session['deadline_error'] = True
return HttpResponseRedirect(request.path)
circle.deadline = deadline
circle.save()
request.session['circle_saved'] = True
return HttpResponseRedirect(request.path) #here a different context is sent on page load
except Exception as e:
print e.message
else:
return HttpResponseRedirect(request.path)
return HttpResponseRedirect(request.path)
This code works the way I want it and creates a circle. But this happens when I perform this on localhost. When I try it on the server, it doesn't work.
The problem lies in the line "circle.save()"
I used multiple print statements to find out the problem. The printing stops when it encounters "circle.save()" line. After that it redirects me to the same page.
Can anyone suggest some solutions?
