Django 序列化

利用 from django.core import serializers 的方法实现。

from django.core import serializers
data = serializers.serialize("json", SomeModel.objects.all())
data1 = serializers.serialize("json", SomeModel.objects.filter(myfield1=myvalue))

  objects = PersonManager()
  first_name = models.CharField(max_length=100)
  last_name = models.CharField(max_length=100)
  birthdate = models.DateField()
  def natural_key(self):
    return (self.first_name, self.last_name)
  class Meta:
    unique_together = (('first_name', 'last_name'),)

<pre name="code" class="python"><span style="font-size:18px;">serializers.serialize('json', queryset,use_natural_foreign_keys=True, use_natural_primary_keys=True)</span>
