Re: Accessing FK sets in model methods
This error message is to do with a syntax error... It doesn't have anything
to do with django specifically. If you've cut and pasted verbatim, then you
need a colon ( : ) at the end of your if > 0 line. This is what python
is flagging as an error as far as i can see.

Re: Accessing FK sets in model methods
You're correct I did have a extra space, but the original problem was
syntax error on the following line :
if self.segment_set.count() > 0
so my question is : can I acess to FK queryset as described in
http://www.djangoproject.com/documentation/db-api/#Backward in a model
method
thanks

If you did a copy of your actual code, line #8 ("def
_first_date(self):") seems to have an extra space worth of
indentation from the User/Notes lines.
Python would flag this as bogus, which in turn would likely
trigger an error in validation.

Accessing FK sets in model methods
Hi,
My name is Ilan, and I kind of new working with Django.
I have a question about model methods.
I trying to write a model method which access ForeignKey FOO_set
functionality
Whoever it does not seems to pass the "syncdb" validation, because of
invalid syntax
Can someone point me to the problem?
#
from django.db import models
from django.contrib.auth.models import User
class Base(models.Model):
User = models.CharField(maxlength=200)
Notes = models.CharField(maxlength=200) # free text
def _first_date(self):
""" Return the first date """
if self.segment_set.count() > 0
return(self.segment_set.order_by('create_date')
[0].create_date)
first_date = property(_first_date)
class Segment(models.Model):
base = models.ForeignKey(Base)
create_date = models.DateTimeField(auto_now_add=True)
update_date = models.DateTimeField(auto_now=True)
Notes = models.CharField(maxlength=200) # free tex
#
D:\Sites\mysite>python manage.py syncdb
Error: Couldn't install apps, because there were errors in one or more
models:
mysite.traveler: invalid syntax (models.py, line 8)
