QUESTION
I have a special need to hash the username, and also I need to keep the usernames unique for my purpose. So, my question is can I override default '_id' field of mongoDB with sha256 hash of username? I read that _id needs to be unique and already indexed, so why would I want to create another entry instead of storing in _id.
Does this cause any technical problems which I'm unaware of? Is it efficient when searching _id as it is indexed?
This application is a Flask application using Flask-pymongo as mongo driver and helper.
By default:
_id : ObjectId(...)
I need:
_id : sha256(username)
Please explain if there are any issues with this approach.

Answered 2022-Apr-04 at 15:05Technically, there is no problem with using sha256 for the value of _id. The default ObjectId type in MongoDB is convenient for creating a unique value "on the spot" but not required. The bit pattern in _id has to be unique, that's all.
From a data design perspective, if you use a function on user data (e.g. sha256) to create material that is linked to the physical DB mechanics (like _id) you must make sure that the user data does not change over the lifetime of the data. In this case, username may be OK but email address for example might be poor because a user could change their email address.

I am trying to dockerize my Flask API. As soon as I try to start my image I receive the message:

QUESTION
I'm getting version clashes when I try to build a dockerfile. This doesn't happen when I run pip install -r requirements.txt in a local venv. I ran pipdeptree in my local venv after installing and found no clashes. This is only occuring when I try to build with docker through the eb cli.
I'm running docker-ce 19.03.9. Both my local venv and my dockerfile are configured to run Python 3.6. I've been unable to contact the original developer and I'm not that familiar with docker so I'm not sure where to go from here other than installing different versions of docker and trying again.
As requested, here is the dockefile;

Answered 2021-Sep-27 at 12:09The instructions Pip helpfully links you to explain what's going on, and it is indeed a bit of a hairy situation.
There is already an Beanstalk application that's running EC2s with docker containers that work just fine with these requirements so I'm not sure why this is happening now.
As to "why this is happening now" – two things I can think of:
- The Pip version in your base image has been updated; newer versions are smarter about conflicting dependencies (in that they refuse to install package constellations that might/should not work).
- Because your requirements.txt isn't necessarily fully locked down; there are transitive dependencies that get installed that aren't listed in the file that have become incompatible with one another.
However, since you already do have working container images, that's great! You could simply do
QUESTION
I'd like to write some unit tests of our mongo code using mongomock as the backend. However, Flask-PyMongo adds a convenience class (find_one_or_404) on top of the Collection class that means that I can't do a straight-up MongoMock substitution. Any attempts at monkeypatching this function onto the Collection class don't seem to be working (I assume it has something to do with the overridden __getattr__ - every time I try I get TypeError: 'Collection' object is not callable on db.collection_name.find_one_or_404({})). What are my options here, besides just not using this function?

Install flask-pymongo
You can use flask-pymongo like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
