I'm trying to make a webservice that outputs XML representation of
data from a model. The model itself looks roughly like this:
---------
class Product(models.Model):
short_description=models.CharField(max_length=300)
long_description=models.CharField(max_length=2000)
price=models.DecimalField(decimal_places=2, max_digits=6)
store=models.ForeignKey(Merchant)
def __unicode__(self):
return self.short_description
class Merchant(models.Models):
name=models.CharField(max_length=20)
zip=models.CharField(max_length=6)
category=models.CharField(max_length=10)
<various other fields>
def __unicode__(self):
return self.name
----------
What I've done so far is this:
----------
zip='12345'
category='food'
products_list=Product.objects.filter(store__zip=zip,
store__category=category)
xml=serializers.serialize("xml",products_list,field=('short_description','price','store'))
--------
It works, and I get XML back, but the 'store' data is just the id for
the Merchant table. What I want instead is the name of the store. I've
tried replacing 'store' with 'store.name' and 'store__name' to no
avail -- how can I get the XML serializer to return a data member of
the 'store' object instead of just a pointer to that object?
If it's not possible with serializer, what's the best way to do it?
Thanks
Andrew
