django - ModelForm not getting saved on server -

i have view uses modelform create circles. works fine on localhost on server, data not getting created since "save" method 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)         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 different context sent on page load             except exception e:                 print e.message         else:             return httpresponseredirect(request.path)         return httpresponseredirect(request.path) 

this code works way want , creates circle. happens when perform on localhost. when try on server, doesn't work. problem lies in line "circle.save()" used multiple print statements find out problem. printing stops when encounters "circle.save()" line. after redirects me same page.

can suggest solutions?
