Question

这是我的字典

{u'krishna': [u'vijayawada', u'gudivada', u'avanigada']}

我想迭代项目并保存在数据库中，我的模型是

class Example(models.Model):
  district = models.CharField(max_length=50,**optional)
  taluk = models.CharField(max_length=20,**optional)

它应该保存为：

 -----------------------------
 |district   |         taluk  | 
 |-----------|--------------- | 
 |krishna    | vijayawada     |           
 |-----------|----------------|
 |krishna    | gudivada       |
 |----------------------------|         
 |krishna    | avanigada      |
 ------------------------------

Answer 1

您可以这样做：

form models import Example

places = {u'krishna': [u'vijayawada', u'gudivada', u'avanigada']}

for district in places:
    for taluk in district:
        e = Example(district=district, taluk=taluk)
        e.save()

Answer 2

for key in dict:
    for value in dict[key]:
         example = Example()
         example.district = key
         example.taluk = value
         example.save()

Answer 3

这对你有用： -

for districtName in places.keys():
    for talukName in places[districtName]:
        print districtName,talukName #Try to print it
        addData = Example.objects.create(district=districtName,taluk=talukName)
        addData.save()

如何迭代字典并保存到python2.7中的数据库？
