我正在寻找一种方法来序列化整个对象及其所有关系。我现在似乎只能从序列化程序中获取主键。
这是我的模型:
class Action(models.Model):
name = models.CharField('Action Name', max_length=250, unique=True)
message = models.TextField('Message', blank=True, null=True)
subject = models.CharField('Subject', max_length=40, null=True)
recipient = models.ManyToManyField('Recipient', blank=True, null=True)
def __str__(self):
return unicode(self.name).encode('utf-8')
def __unicode__(self):
return unicode(self.name)
class Recipient(models.Model):
address = models.EmailField('Address', max_length=75, unique=True)
businessHours = models.BooleanField('Business Hours Only', default=False)
def __str__(self):
return unicode(self.address).encode('utf-8')
def __unicode__(self):
return unicode(self.address)
我在这里运行序列化程序:
all = serializers.serialize('xml', list(Action.objects.select_related().all()))
如果我运行 print all 我得到的输出只是列出了收件人字段的主键。
<field type="CharField" name="subject">On The Road Productions</field>
<field to="sla.recipient" name="recipient" rel="ManyToManyRel">
<object pk="29"></object>
</field></object>
<object pk="11" model="sla.action">
<field type="CharField" name="name">On The Road Productions</field>
<field type="TextField" name="message">
我还需要相关收件人的所有属性。知道我怎么能得到这个吗?

我在 xml_serializer.py 中找到了这篇文章,但我不确定如何修改它。
def handle_m2m_field(self, obj, field):
"""
Called to handle a ManyToManyField. Related objects are only
serialized as references to the object's PK (i.e. the related *data*
is not dumped, just the relation).
"""
if field.creates_table:
self._start_relational_field(field)
for relobj in getattr(obj, field.name).iterator():
self.xml.addQuickElement("object", attrs={"pk" : smart_unicode(relobj._get_pk_val())})
self.xml.endElement("field")
