unable Integrating Djongo 1.3.1 with django 2.2.10

[Eswar Subramanyam]

Hi 

I opted for Djongo to take advantage of Django ORM with MongoDB..

but while starting the server, i get the following error

AppData\Roaming\Python\Python38\site-packages\django\db\utils.py", line 121, in load_backend

    raise ImproperlyConfigured(

django.core.exceptions.ImproperlyConfigured: 'djongo' isn't an available database backend.

Try using 'django.db.backends.XXX', where XXX is one of:

    'mysql', 'oracle', 'postgresql', 'sqlite3'

I have lost a lot of time trying to figure out, and came to a conclusion that i cant use ORM on Mongo DB.

Have someone got a clue on what going wrong ?

I dump also all the installed packages

Thanks for your help/

Hi Eswar,

May Peace, Blessings & Mercy of Almighty God be on you!

Short answer, your environment is messed up. Now, let us address who or how was it messed up

There are many reasons why you could be getting this error. 

One major issue similar I have frequently faced is in case you have multiple versions of Python on the same box. Python 2.x & 3.x installed on the same box. Django version 1.x is compatible with Python 2.x.  Python 3.x & django 1.x do not work together. In case you have multiple versions of Python installed, you may have to tweak the PATH to indicate the appropriate directory in the search path ahead of the other directories. 

This is probably your reason for the stuff not working as you have both 2.2.11 & 1.3.1 of Django installed.   

1. You may be using an IDE like pycharm/spyder/any other IDE. Normally, these IDEs try to download packages. In case there is a version mismatch in the source of the package, there could be a mess up.

2. Your PATH & PYTHONPATH environment variable may not have the relevant directory or have a different directory with the same file name ahead of the actual file you want loaded.

3. You may be using a virtualenv. Try to deactivate & try executing the same

  

Hope this helps. 

Kindly share your experience.
Thanks in advance. 

God Bless You!
God Bless India!!

Hi Khaleel

God bless you and your family too. 

I understand your point, but i have only one python 3.8 installed. And Django version is 2.2.1. other package 1.3.1 isnt Django but Djongo, so i am not able to figure out where this is issue is cropping up. i cleaned also the pyharm packages but still doesnt work.

Thank you for your help.

Kind Regards

Es.

Hi Khaleel and whoever this may help in the future,

Actually you were right Khaleel, on those lines i checked this thread which was useful to me.

https://stackoverflow.com/questions/122327/how-do-i-find-the-location-of-my-python-site-packages-directory

Following which i was stareing at the exception and realised that the clue which was in front of me since hours to resolve this issue.Like in Java, python gives you the root cause of an exception, but as i was used to Java and .Net i didnt realise the annotation used by python.

The exception i was bothered about the exception:

AppData\Roaming\Python\Python38\site-packages\django\db\utils.py", line 121, in load_backend

    raise ImproperlyConfigured(

django.core.exceptions.ImproperlyConfigured: 'djongo' isn't an available database backend.

Try using 'django.db.backends.XXX', where XXX is one of:

    'mysql', 'oracle', 'postgresql', 'sqlite3'

Where as python had already listed the root cause which was :

\Python\Python38\site-packages\djongo\database.py", line 2, in <module>

    from pymongo import MongoClient

ModuleNotFoundError: No module named 'pymongo'

The above exception was the direct cause of the following exception:

Indeed that's where Khaleel you were right, PyMongo i installed through pycharm, which desginated a sitepackage folder that wasnt my user site-package...

Hope this helps someone falling into the same trap.

Cheers,

Es.

HI Eswar,

May Peace, Blessings & Mercy of Almighty God be on you!

I should I realized it earlier. It would have saved your time.

In Python, we read the last line in the list of errors & do not really care for the earlier errors.

Thanks you very much for the update. 

God Bless You!
God Bless India!!

Install pymongo package by > pip install pymongo

or, better practice

make a virtual environment directory where all your dependencies will be installed.

> python -m venv  myvenv (assuming you name it myvenv)

If you are in Windows 

activate virtual environment with:

> cd in directory where you created virtual environment

> myvenv\Scripts\activate

Make sure you have pip installed

> pip install pymongo

then you won't have this error.
