Django Mongo SQLDecodeError at /admin/
Question:
I have been experimenting with mongodb with Django. I created a super user, and then proceeded to http://localhost:8000/admin/ to login. Upon entering my credentials, and submitting them, the error given at the end of this post occurred. I have 2 other apps in this project and have also commented the line where the admin can register the model in appname/admin.py, i.e.:
#admin.site.register(Tweet)
How can I fix this?
If you would like any further information about the code or from certain files please let me know and I will edit it in 🙂
I assume the error is caused with the way mongo and django is workign together but have no idea how to correct it.
I am sure the python installation, and routes all work correctly as they were configured with the assistance of the department admins.
NOTE: some of the routes are due to custom installation of Python in case it seems extremely weird. I am using a Department machine to do my work, hence the paths.

Answers:
thanks to @oluwafemi-sule comment, the problem has been corrected.
I have updated to Mongo 3.6.3 to resolve this issue.
Error: “djongo.sql2mongo.SQLDecodeError: FAILED SQL: SELECT”
Solution: Here you can simply see that SQL is failed, hence first install mysqlclient and then run the command.
sudo apt-get install mysql-client
Reason: Pymongo wants to convert sql(Default query language) query to mongoDB query but unable to process it because of missing mysql pluggins.
Maybe try upgrading Django to version 3.1.7 or above. I got an SQLDecodeError when I tried to migrate and I solved it by upgrading Django and running makemigrations again before migrating. The previous Django version that I had was 2.1.7 and apparently the migration file generated by these two versions are very different.
I downgraded my django version to 3.2 and it worked for me.
pip install django==3.2
I have been experimenting with mongodb with Django. I created a super user, and then proceeded to http://localhost:8000/admin/ to login. Upon entering my credentials, and submitting them, the error given at the end of this post occurred. I have 2 other apps in this project and have also commented the line where the admin can register the model in appname/admin.py, i.e.:

Pymongo error: OrderedDict([('errmsg', "exception: Unrecognized pipeline stage name: '$lookup'"), ('code', 16436), ('ok', 0.0)])
Version: 1.2.23
thanks to @oluwafemi-sule comment, the problem has been corrected.
I have updated to Mongo 3.6.3 to resolve this issue.
Error: “djongo.sql2mongo.SQLDecodeError: FAILED SQL: SELECT”
Solution: Here you can simply see that SQL is failed, hence first install mysqlclient and then run the command.
sudo apt-get install mysql-client
Reason: Pymongo wants to convert sql(Default query language) query to mongoDB query but unable to process it because of missing mysql pluggins.
Maybe try upgrading Django to version 3.1.7 or above. I got an SQLDecodeError when I tried to migrate and I solved it by upgrading Django and running makemigrations again before migrating. The previous Django version that I had was 2.1.7 and apparently the migration file generated by these two versions are very different.
I downgraded my django version to 3.2 and it worked for me.
pip install django==3.2
