class initialmessage(models.model): json = models.textfield() att_url = models.charfield(max_length = 254, default='https://outlook.office365.com/api/v1.0/me/messages/{0}/attachments') send_url = models.charfield(max_length = 254, default='https://outlook.office365.com/api/v1.0/me/sendmail') update_url = models.charfield(max_length = 254, default='https://outlook.office365.com/api/v1.0/me/messages/{0}') id_email = models.charfield(max_length = 254,unique=false) subject = models.textfield() body_content = models.textfield() body_type = models.textfield() importance = models.charfield(max_length = 254) hasattachments = models.booleanfield(default=false) parentfolderid = models.charfield(max_length = 254) e_from = models.textfield() sender = models.textfield() conversationid = models.textfield() categories = models.textfield() datetimesent = models.datetimefield() datetimereceived = models.datetimefield()  status = models.charfield(max_length=2, choices=initialmessage_status, default='p') claim = models.onetoonefield(claim, null=true, blank=true, default=none)  def load_json(self):     m_json = json.loads(self.json)      try:         email = initialmessage.objects.get(id_email = m_json['id'])     except initialmessage.doesnotexist:         email = none      if email none:         self.id_email = m_json['id']         self.subject = m_json['subject']         self.body_content = m_json['body']['content']         self.body_type = m_json['body']['contenttype']         self.importance = m_json['importance']         self.hasattachments = m_json['hasattachments']         self.parentfolderid = m_json['parentfolderid']         self.e_from = m_json['from']         self.sender = m_json['sender']         self.conversationid = m_json['conversationid']         self.categories = m_json['categories']         self.datetimesent = m_json['datetimesent']         self.datetimereceived = m_json['datetimereceived']         self.save()     else:         m_json = 'duplicated'     return m_json

and code i'm using save each new email:

log.debug('fetching messages.')     response = requests.get(self.inbox_url,auth=self.auth,params={'$filter':self.filters})     log.info('response o365: %s', str(response))     message in response.json()['value']:         m = initialmessage(json = json.dumps(message)).load_json()     log.debug('all messages retrieved , put in list.')     return true
