I'm trying to queue up some build requests in a DB during a changegroup hook. The DB table is managed by a Django app. So, in the hook, I want to use the Django model to submit the build request. However, I'm unable to get my settings right to import the model successfully.
Based on this (https://docs.djangoproject.com/en/1.3/ref/django-admin/) info, all I need to do is add my django site to the sys path, and set the DJANGO_SETTINGS_MODULE. The django site lives in /opt/mysite, so - trying this from the python console:
>>> import sys
>>> import os
>>> sys.path.append('/opt')
>>> os.environ['DJANGO_SETTINGS_MODULE'] = 'mysite.settings'
>>> from mysite.myapp.models import Build
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/opt/mysite/myapp/models.py", line 1, in <module>
from django.db import models

__import__(name)
File "/usr/lib/pymodules/python2.7/django/db/backends/mysql/base.py", line 28, in <module>
from django.db import utils
ImportError: cannot import name utils
>>>
Second Attempt:
Based on this (http://www.b-list.org/weblog/2007/sep/22/standalone-django-scripts/) I can use setup_environ(), when I try this in the python shell, it works:
>>> import sys
>>> sys.path.append('/opt')
>>> from django.core.management import setup_environ
>>> from mysite import settings
>>> setup_environ(settings)
'/opt/mysite'
>>> from mysite.myapp.models import Build
>>> Build.objects.all()
[<Build: #1 F nkj sdfsdfsdfs43qg test_branch>, <Build: #2 F nkj sdfsdfsdfs43qg test_branch>, <Build: #13 Q >, <Build: #14 Q nkj_bug243>, <Build: #11 F nkj 444hwe45hedrrt nkj_bug272>, <Build: #12 F nkj sdfsdfsdfs43qg test_branch>]
However, when I try this in my Mercurial hook, I get blasted with errors the minute I try to import my Build model:
#!/usr/bin/env python
import sys
path = '/opt'
if path not in sys.path:
sys.path.append(path)
from django.core.management import setup_environ
from mysite import settings
setup_environ(settings)
from mysite.myapp.models import Build
import datetime
... do stuff ...
When it gets to the 'from mysite.myapp.models import Build' line I get the following error output:

'%r: %s' % (name, e))
ValueError: Unable to configure handler 'mail_admins': __import__() argument 1 must be string, not DictConfigurator
Any ideas as to what could be causing this problem?
The DictConfigurator error is a bug in python, hopefully fixed in the next 2.7 release (http://bugs.python.org/issue12718), something (probably mercurial) is overriding import and python's logging code fails in that case.
Until then here is what I did to fix it. Copy dictconfig.py from django/utils to somewhere in your python system path (I put it alongside my hook). Change the line
importer = __import__
to:
def importer(self, *args):
return __import(*args)__
And then in settings.py for your django project add to the end:
LOGGING_CONFIG = 'website.dictconfig.dictConfig'
Update website.dictconfig to whatever path you put the dictconfig file into so python can find it.
UPDATE: I think there is an even easier way. Add this to the top of your hook script, before importing anything else:
from mercurial import demandimport;
demandimport.disable()
This makes Mercurial revert the import override and seems to solve the problem cleanly.
If you're running with your environment in a virtualenv dir you'll need to add that to the site packages and I'd also suggest that you put the django dir at the front of sys.path instead of the end.
Here's the code we use to integrate our Django app into other python apps.
import os
import sys
# point this at the virtualenv dir that your django deployment runs out of
# you are using virtualenv. right?
DJANGO_ENV = '/home/core/python-envs/production'
# where your code lives (ie where settings.py is)
DJANGO_DIR = '/home/core/code/production'
# add our site packages
import site
site_packages = os.path.join(DJANGO_ENV, 'lib', 'python%s' % sys.version[:3], 'site-packages')
site.addsitedir(site_packages)
# put the main Django directory on first
sys.path.insert(0, DJANGO_DIR)
# setup the Django environment pointing to our settings
import settings
import django.core.management
django.core.management.setup_environ(settings)
# finally, import our objects
from yourapp.models import YourModel
One last thing to note is that when we import our code into some applications we've run into scoping issues and imports clashing. To get around it we wrap the work we want to do in a function so that it gets its own scope.
For example, instead of:
from yourapp.models import YourModel
objs = YourModel.objects.filter(something=True)
...
Do something like:
def do_work():
from yourapp.models import YourModel
objs = YourModel.objects.filter(something=True)
...
do_work()

I'm getting the exact same error while running my .py script also,here's the script:
from flask import Flask
import os
from flask_sqlalchemy import SQLAlchemy
from flask_migrate import Migrate
basedir = os.path.abspath(os.path.dirname(__file__)) #Full directory path of the file I'm working with..here, sql1.py
app = Flask(__name__)
app.config['SQLALCHEMY_DATABASE_URI'] = 'sqlite:///' + os.path.join(basedir, 'data.sqlite')
app.config['SQLALCHEMY_TRACK_MODIFICATIONS'] = False
db = SQLAlchemy(app)
Migrate(app,db) #Here it connect the application "app.py"
# with the database "db"
class puppy(db.Model):
__tablename__ = 'Name Provided by me!!'
id = db.Column(db.Integer,primary_key = True)
name = db.Column(db.Text)
age = db.Column(db.Integer)
def __init__(self,name,age):
self.name = name
self.age = age
def __repr__(self):
return f"puppy {self.name} is {self.age} year/s old!"
I looked into every solution I found (here and this)and made sure everything was correct! I ran this command when my environment was activated which had installed every package needed including SQLAlchemy and Flask-Migrate.
I even deleted them (packages) and re-installed their latest versions but still getting the same error!
I'm using Python 3.8.5
You have some dependencies that are too old and incompatible with Python 3.8. At the very least, you should update the mako package:
pip install --upgrade mako
I had a similar issue I had to update flask_sqlalchemy even after doing this I had issues. I ended up having to make a new virtual environment, I would make a small hello world project on another virtual environment to see if that works.
For me, it was giving the same error, so I removed __init__.py file from the folder which has app.py
After removing I ran the
flask init db
it worked :)
Trying to use django-shopify-sync in a Django 1.9 project. When loading the config for the app it gives me the following error, likely because it's trying to load some models in the config?
Tried moving the the two imports that eventually import models into the ready() function below, but still getting the same error. Culpirt lines 2 and 3 in the following file https://github.com/andresdouglas/django-shopify-sync/blob/master/shopify_sync/apps.py
The error is:

It looks like you may have an ordering issue. Make sure your application is in the INSTALLED_APPS tuple after django-shopify-sync. You can find a few more details in the Application registry documentation.
As unsatisfying as an inline import is, you may be stuck with it. I'd suggest moving
from shopify_sync.handlers import webhook_received_handler
from shopify_webhook.signals import webhook_received
into the ready method in apps.py. This will delay the import until the models are ready.
The change I tried is:
diff --git a/shopify_sync/apps.py b/shopify_sync/apps.py
index 663b43b..0bc1fcc 100644

What can it be the problem? I have django in directory C:\Python27\Lib\site-packages\django\db and in there i have a file called models.
This is the pic
Bizarre isn't it?
Not all of Django supports simply being loaded as a Python module, unfortunately; you need to use the means provided by Django itself to bootstrap the environment needed to load stuff like models.
One option is to use the Django shell but it's also possible to use a purely programmatic solution from your own code. See https://docs.djangoproject.com/en/dev/topics/settings/ for all the options.
Here's also an example by somebody else https://gist.github.com/jordanorelli/1025419 but I haven't verified if it's up to date.
The answer is in the error message:
You must either define the environment variable DJANGO_SETTINGS_MODULE or...
For this reason Django provides a shortcut to loading a python shell with Django settings configured:

If it is possible I would like to turn off the template functionality as I use python only for JSON output for mobile app.
if you create python module you should add __init__.py in top of your hierarchy:
dvedit/
__init__.py
clipview.py
filters/
__init__.py
it means that in every directory which will be imported via from ... import ... should have __init__.py file.
further info available: http://wiki.cython.org/PackageHierarchy
I am creating unit test py file (tests.py) then i received the below error messages.
Could you give me some idea on how to resolve it.

Any guidance on the right direction is appreciated.
UPDATES1
I add my tests.py source code

FAILED (errors=43)
Here's what I did to solve this problem without any changes to code:
Go into the project properties in Eclipse
Go to "PyDev - PYTHONPATH" and then to the tab "String substitution variables"
Click "Add variable"
Name: "DJANGO_SETTINGS_MODULE", Value: location of your settings module (like "py23.settings" in the answer by eros)
That did it for me, at least.
I just add the following:
import os
from os.path import abspath, dirname
import sys
# Set up django
project_dir = abspath(dirname(dirname(__file__)))
sys.path.insert(0, project_dir)
os.environ['DJANGO_SETTINGS_MODULE'] = 'py23.settings'
