flask-mongoengine | MongoEngine flask extension with WTF model forms support | Form library

What you want is the request context, not the app context.

Flask includes some handy functions to push a request context for you - check out the Flask testing docs and you'll see a lot of relevant info, including the test_request_context method on the app object.

Combine that with app.test_client to push a request context and then simulate client behaviour such as POSTing to your endpoint. Try this:

This seems to work for me with conda 4.8.3 and mamba 0.4.3, Ubuntu 18.04.

I know nothing about flask-mongoengine but it seems the recipe here hasn't been updated for 5 years and it doesn't seem very popular.

Does it help if you do it through app.config['MONGODB_SETTINGS']? e.g.

The error message error: invalid command 'bdist_wheel' means, Python can't find the wheel module. Install the wheel module first by pip install wheel and then pip install flask-mongoengine.

After doing some digging into the Mongoengine source code, I found out that it uses the PyMongo cursor sort which itself wraps the queries made to MongoDB. In other words, my Document definition is too high in the chain to even affect the order_by result.

As such, the solution I went with was to write a classmethod. This simply takes in a mongoengine.queryset.QuerySet instance and applies a sort on the version attribute.
