python - How to send data set to multiple rows in same table using save method (in Django 1.8 / SQLLIte )? -

i code project using django 1.8. model class.

 # encoding: utf-8 django.contrib.auth.models import user django.db import models django.utils.encoding import python_2_unicode_compatible django.utils.timezone import .algo import  algo django.http import httpresponse     @python_2_unicode_compatible class key_gen(models.model):     key_beging_code =models.decimalfield('brand_name +pack_size' ,max_digits=5, decimal_places=2)     key_quantity    =models.decimalfield("key quantity" ,max_digits=19, decimal_places=10)     key_code        =models.charfield('key code' ,max_length=50 , unique=true)     is_public = models.booleanfield('public', default=true)     date_created = models.datetimefield('date created',auto_now_add=true)     date_updated = models.datetimefield('date updated',auto_now_add=true)        class meta:         verbose_name='key_gen'         verbose_name_plural='keys_gen'         ordering = ['-date_created']       def __str__(self):         return '%s' % (self.key_code)          def get_key_code(self,x,y):         alist = []         x = algo(int(x),int(y),alist)         keys =x.id_generator()         return keys       def save(self, *args, **kwargs):         if not self.key_code:             self.key_code_temp =self.get_key_code(self.key_beging_code,self.key_quantity)         self.key_code_temp =self.get_key_code(self.key_beging_code,self.key_quantity)          i=0;         x in self.key_code_temp:             +=1;             self.key_code = self.key_code_temp[i-1]             super(key_gen, self).save(*args, **kwargs) 

i call algo function , return data list function.

self.key_code_tempt=self.get_key_code(self.key_beging_code,self.key_quantity) #eg . ['001r','ou3r', '4002'] 

i want send data 1 one database table.but current send 1 value database.

i put loop iterate list , call '.save' method repeatedly.but doesn’t show call repeatedly. new comer python web programming , hope expert help.i notice key list pass , loop inside save method run once.

============view class code==================================

  @login_required def key_create(request):     if request.method == 'post':         form = keygenarateform(data=request.post)         if form.is_valid():              request.post._mutable = true                       key_gen = form.save(commit=false)                key_gen.save()               return redirect('marcador_bookmark_user',username=request.user.username)     else:         form = keygenarateform()     context = {'form': form, 'create_key': true}     return render(request, 'marcador/key_genarate_form.html', context) 

this sqllite db table. think , can more idea see image.
