How Django skipping an app when using syncdb command
I have a Django project which has two apps (one created as debug test). For the debug test, syncdb does put the model in the database but for the other it does not.
- Both are in
settings.INSTALLED_APPS
. - There are around seven models, none of them being recognized.
- Neither the server, any page or the syncdb-console give any errors.
- Models are in a models directory. As a test, there is also one in app/models.py (doesn't work either).
- Most strikingly to me is that the below code does display the models which aren't synced (executed from the app that is skipped):
for model in get_models():
models.append(model)
pass models to a template
Any help would be much appreciated. I think it is something trivial but I'm out of ideas for things to try.
Thanks,
UPDATE:
INSTALLED_APPS = (
'django.contrib.auth',
'django.contrib.contenttypes',
'django.contrib.sessions',
'django.contrib.messages',
'django.contrib.admin',
'techtree',
'froink',
)
Structure:
project/techtr开发者_C百科ee/models.py
(contains a test model)project/techtree/models/__init__.py
(as described here)project/techtree/models/typ.py
(contains model Type)
There are more files of the same type as the last line.
Are you missing the __init__.py
file in the second app's models directory? That would mean it can't be found on the path.
Can you show us your INSTALLED_APPS
setting, and your directory structure please?
Looking at your directory structure, I think I can guess what's wrong.
my_app/
__init__.py
my_module.py
my_module/
__init__.py
my_python_file.py
With the above fictional directory structure, what gets imported when I do the following?
from my_module import *
Does that import everything from within my_module.py
or everything within the my_module
directory?
Use one, or the other. Not both. Put everything inside your models.py
file, and get rid of the directory unless you have a good reason for having a models
directory. You probably don't.
I faced this same problem, It took hours for me to figure out how to group models in to a separate directory. Heres how to do it,
Add a meta class to each of your models with an app_label parameter.
from django.db import models
class Test(models.Model):
class Meta:
app_label = 'myapp'
Here's where I found out about this, Placing Django Models In Separate Files
But doing this wasn't enough you have to import the models in an __init__.py
file in the models directory like this,
from YourModelFile import *
Django is usually searching for a models.py
file only. If you have models.py
and a module sub directory called models
with an __init__.py
file it is not recognizing the models correctly (my guess). You can do one of these two:
- Remove your sub-module completely and keep all your model definitions in
models.py
OR
- Remove
models.py
intechtree
. Add amodels.py
file to yourtechtree.models
app where you keep the model definitions. Add'techtree.models'
to yourINSTALLED_APPS
(just'techtree'
is no enough).
Hope one of these answers helps.
Check the file name is
__init__.py
and not
init.py
