Hi,
I am trying to set up api with django-piston handler method. But the
code is not very stable. Sometimes web request (site/api/locations/
aggregated/) can get the data, sometimes it crashes with "maximum
recursion depth exceeded while calling a Python object" error. I am
wondering if anybody can shed some light on this.
Django: 1.2.1
piston: 0.2.2
python: 2.6.5
The models:
class Service(models.Model):
serviceid = models.AutoField(primary_key=True,
verbose_name="Service ID")
.....
locationid = models.ForeignKey('Location',db_column='locationid',
related_name='services',verbose_name="Location",
help_text="required") .......
class Location(models.Model):
locationid = models.AutoField(primary_key=True,
verbose_name="Location ID")
name = models.CharField(max_length=255,null=False, blank=False,
help_text="required",verbose_name="Location Name" )
locationtypeid = models.ForeignKey('Locationtype',
db_column='locationtypeid',
help_text="required",verbose_name="Location Type")
.....
(I only included the relevant fields in this post)
handler.py:
class LocationAggregateHandler(BaseHandler):
allowed_methods = ('GET',)
fields = ('locationid',....'
'locationtypeid',
('services',
('serviceid',....,
'locationid',
)
),
)
model = Location
@classmethod
def locationtypeid(cls, sfk):
return sfk.locationtypeid.locationtypeid
def read(self, name=None):
return self.model.objects.all()
My guess is the locationid field within the services subclass. It
might confuse the emitters.py code and trigger the infinite recursive
loop. But then why sometimes it works?
Thanks for your help.

* build/bdist.linux-i686/egg/piston/emitters.py in _model
I am trying to set up api with django-piston handler method. But the
code is not very stable. Sometimes web request (site/api/locations/
aggregated/) can get the data, sometimes it crashes with "maximum
recursion depth exceeded while calling a Python object" error. I am
wondering if anybody can shed some light on this.
Django: 1.2.1
piston: 0.2.2
python: 2.6.5
The models:
class Service(models.Model):
serviceid = models.AutoField(primary_key=True,
verbose_name="Service ID")
.....
locationid = models.ForeignKey('Location',db_column='locationid',
related_name='services',verbose_name="Location",
help_text="required") .......
class Location(models.Model):
locationid = models.AutoField(primary_key=True,
verbose_name="Location ID")
name = models.CharField(max_length=255,null=False, blank=False,
help_text="required",verbose_name="Location Name" )
locationtypeid = models.ForeignKey('Locationtype',
db_column='locationtypeid',
help_text="required",verbose_name="Location Type")
.....
(I only included the relevant fields in this post)
handler.py:
class LocationAggregateHandler(BaseHandler):
allowed_methods = ('GET',)
fields = ('locationid',....'
'locationtypeid',
('services',
('serviceid',....,
'locationid',
)
),
)
model = Location
@classmethod
def locationtypeid(cls, sfk):
return sfk.locationtypeid.locationtypeid
def read(self, name=None):
return self.model.objects.all()
My guess is the locationid field within the services subclass. It
might confuse the emitters.py code and trigger the infinite recursive
loop. But then why sometimes it works?
Thanks for your help.
