django Admin save_model nicht Sparmodell ändert

Question

Das ist mein admin.py:

class TransactionInfoAdmin(admin.ModelAdmin): 
    search_fields=['transactionId','subscriptionInfo__customerNumber'] 


    save_on_top = False 
    def has_add_permission(self,request): 
     return False 
    def has_delete_permission(self, request, obj=None): 
     return False 
    def get_readonly_fields(self, request, obj=None): 
     if obj: 
      return self.readonly_fields + ('subscriptionInfo','transactionId','authorizationId','responseCode','operation','batchNumber','merchantId') 
     return self.readonly_fields 

    def save_model(self, request, obj, form, change): 


      #SUCCESS ACTIONS 
      obj.subscriptionInfo.paid = 1 
      obj.save() 




     pass 

Als ich die obj.subscriptionInfo.paid = 1 speichere es ist nicht die Datenzeile zu aktualisieren, irgendwelche Ideen, warum?

Hinweis: SubscriptionInfo ist Fremdschlüssel in dem obigen Modell TransactionInfo.

Mein model.py

class SubscriptionInfo(models.Model): 
    subscriptionId = models.CharField(max_length=50) 
    customerNumber = models.IntegerField() 
    subscriptionType = models.CharField(max_length=50, default="basic") 
    currency = models.CharField(max_length=50, default="NOK") 
    paid = models.IntegerField(default=0) 

    class Meta: 
     verbose_name = "Subscription Information" 
     verbose_name_plural = "Subscription Information" 

    def __unicode__(self): 
     return u'%s' % self.customerNumber 


class TransactionInfo(models.Model): 
    subscriptionInfo = models.ForeignKey(SubscriptionInfo, db_column='f') 
    authorizationId = models.IntegerField() 
    transactionId = models.TextField() 
    batchNumber = models.IntegerField() 
    merchantId = models.IntegerField() 
    operation = models.CharField(max_length=50) 
    responseCode = models.CharField(max_length=50) 
    paidDate = models.DateField(_("Date"), default=datetime.date.today) 

    class Meta: 
     verbose_name = "Transaction Information" 
     verbose_name_plural = "Transaction Information" 

    def __unicode__(self): 
     return u'Transaction : %s' % self.pk 

jedermann?

Sie rufen müssen:

obj.subscriptionInfo.save() 

, wie es auf einem separaten Modell ist, wird es in etwa so aussehen:

def save_model(self, request, obj, form, change): 
    #SUCCESS ACTIONS 
    obj.subscriptionInfo.paid = 1 
    obj.subscriptionInfo.save() 
    obj.save()
