djongo and mysql

[devtrk]

Hello there,

I want to use MySQL and Djongo in the same project.

#models.py

from django.db import models
from djongo import models as mongo_models

I get an error because of these lines.

In order for that to work you need to set django up for multiple databases. Check out: https://docs.djangoproject.com/en/2.0/topics/db/multi-db/. Just follow that.

When making migrations, make sure to add —database to target your secoundary database.

This is not an issue with djongo.

[devtrk]

DATABASES = {
'default': {
'ENGINE': 'django.db.backends.mysql',
'NAME': 'test',
'USER': 'root',
'PASSWORD': '',
'HOST': 'localhost',
'PORT': '3306',
'OPTIONS': {'charset': 'utf8mb4'},
},
'mongo': {
'ENGINE': 'djongo',
'NAME': 'test',
'HOST': '*****.mlab.com',
'PORT': 43774,
'USER': 'test',
'PASSWORD': 'test',
}
}

Multi connected as database. I'm running --database=mongo.

Have you written a router?

From my understanding it seems like you need to use one database / app. You importing both in the same file makes me think you are using both databases in the same app.

If you have, when is this problem occuring? When running migrations?

[devtrk]

I did not write a router. I want to select the database manually. Yes, it gives an error in the "makemigrations" command.

[halvorboe]

Your problem is that the package django.db.models.fields.mixins does not exist.

[devtrk]

but removing "from djongo import models as mongo_models" does not give an error.

[halvorboe]

This is simply a problem with this import:
ModuleNotFoundError: No module named 'django.db.models.fields.mixins' <- this is not a package

[devtrk]

Is this package incompatible with django 1.11?

[halvorboe]

Please link me to the documentation for: django.db.models.fields.mixins
From what I can see it does not exist. Please, I don't think this has anything to do with djongo.

[devtrk]

Yes Django is not available in 1.11. It's in 2.0.

[halvorboe]

Checked it now, I get the same error with django 1.11. That is the problem.

Just revert to djongo 1.2.23 for now and its all good. 1.2.24 is the breaking update.
OR
Use django 2

[pranay16]

Running into the same issue....downgrading to 1.2.23 for now.

[nesdis]

Django 1.8 is the minimum required for running this package

[pranay16]

Got it.
Would be helpful if it was mentioned in the Requirements in the readme
:)

Thanks!
