Thanks for the video!! is not easy to find a professional and simple way to setup flask and pymongo and it really helped me

Anthony, I love your tutorials, also the flask one on Udemy. Some of the material there looks a bit dated, could you please consider having a Flask-Mongo-Heroku unit added with the newer technology available? It would be great to see how you do this, including a register/login/logout part and interacting with the database in some way. Thanks!

Hi! Thanks for the informative video. I was wondering if you had planned on making an extension to include the rest of CRUD?

I noticed pipenv takes much longer than bare pip to install basic requirements. I know it makes a lot of other stuff as well, but still, the wait can get pretty annoying over time.

This is the most difficult way I've ever seen pymongo set up.

I tried connecting mongoalchemy with atlas but it doesn't accept the uri from atlas. Is there a solution for this?

I have no idea what you're talking about.:D

You made your life easier by modularizing the code but it's confusing for a tutorial.

I have the same problem as "Danny corgan", that is:
I created a script to populate my database. It reads informations from a .txt file and appends it all to a list which is used with insert_many method from pymongo. However, I'm not quite sure I can reference my database object in the script. I definitely can hardcoding the information:
from flask_pymongo import PyMongo
from pymongo import MongoClient
...
# Connect to database
client = MongoClient('...')
db = client.homophones
homophonesCollection = db.homophones

This way I can use my Collection as I wanted. However, this is far from ideal and this way my URI is exposed.
If I use this instead:
from .extensions import mongo

I get this right away:
File "populate_db.py", line 12, in <module>
from .extensions import mongo
ModuleNotFoundError: No module named '__main__.extensions'; '__main__' is not a package

Removing the dot before "extensions" and copying main.py's instantiation of Collection:
from extensions import mongo
...
user_collection = mongo.db.users

This happens:
File "populate_db.py", line 18, in populate_db
user_collection = mongo.db.users
AttributeError: 'NoneType' object has no attribute 'users'

Any help here? So far I've been able to create a web application thanks in great part to you put that heavily modular setup seems to have confused a lot of folks here. I searched quite a bit and couldn't figure out what to do. Can you elaborate more how can I connect to my database/get database object in a different script inside my flask application (like the populate_db.py I mentioned?)

[XEPICSAMX]

I'm getting 'MONGO_URI' is not defined as an error, any solutions?

[dannycorganrg]

Hello, can we not download MongoDB and use it instead of using the cloud database.
