I don't think I'm making a rookie mistake, I've looked over my code several
times.
I've got two pretty simple django models that are just failing to sync to
the db
during the syncdb there are no errors, even with --verbosity 3
When I try to make a relation to them I get an error saying the models
either don't exist or a re abstract
In fact when I examine the DB, they are not there.
syncdb is attempting to sync models before and after these 2 models in the
same file.
I've dropped my DB and started from scratch several times
I don't know how to debug this issue because I don't know how syncdb works
under the covers and what can go wrong.
Here are my models, they look pretty simple to me:
class DirEnumVal(models.Model):
str_val = models.CharField(max_length=64, default='')
def unicode(self):
return self.str_val
class DirAttr(models.Model):
BOOL = 'BOOL'
MONO = 'MONO'
SCAL = 'SCAL'
ENUM = 'ENUM'
TYPES = (
(BOOL,'Boolean'),
(MONO,'Monomial'),
(SCAL,'Scalar'),
(ENUM,'Enumeration'),
)
val_type = models.CharField(max_length=4, choices=TYPES)
val_key = models.CharField(max_length=32)
default_bool = models.BooleanField(default=True)
default_num = models.IntegerField(default = 0)
default_float = models.FloatField(default=1.0)
enum_choices = models.ManyToManyField(DirEnumVal, null=True, blank=True)
default_choice = models.CharField(max_length=64, default='')
required = models.BooleanField(default=True)
def unicode(self):
return '{k} :=> {t} ( default = {d} )'.format(
k=self.val_key, t=self.val_type, d=self.default())
I am using a pattern with multiple model files for a single app
my dir structure is:
>app
> models
- __init__.py
- model_file1.py
- model_file2.py
and in my __init__.py I've got code to pull all the models together into
one module: app.models
from __future__ import absolute_import
from .model_file1 import model1a,model1b,model1c
from .model_file2 import model2a,model2b,model2c
This way of importing the models has been working long before this trouble
of models not being synched came up.
When I access the django project and settings through a python shell I can
import the models and instatiate them
but when I save them, PostGres gives me this error:
DatabaseError: current transaction is aborted, commands ignored until end of
transaction block
This problem surfaced after I installed django-categories and set up some
category models.
I had some trouble at first setting that up but I've got the BaseCategory
subclasses behaving nicely now
and have started with a fresh DB.
At some point when I was getting django categories to work there was an error
when I synched the DB
that said something about an unexcepted special character being somewhere in my
code or the django-categories code.
That seemed suspicious but that doesn't show up anymore and I'm using a fresh
DB.
Does anybody see anything obvious or know what type of problems can cause
syncdb to ignore models?
I'm running out of ideas about what is wrong
I'm on Django 1.5 using PostGreSQL & MacOS Lion
