blog_flask VS flask-sqlalchemy

I did something like that with flask: https://github.com/bgtti/blog_flask Django would have worked just as well.

I did something similar using flask: https://github.com/bgtti/blog_flask

You should probably use a database for this, using something like sqlite a single file "database" is probably the quickest way to get started, I recommend you use it with Flask-SQLAlchemy which makes working with the db easy as pie.

Flask-SQLAlchemy: An extension that integrates SQLAlchemy with Flask. You can install it using pip install flask-sqlalchemy.

flask-sqlalchemy: ORM for database access

I've made several runs at stripping the essential paginating functionality of flask-sqlalchemy for use with things like lists. That's where I'd start.

You can either use an ORM, which might be sqlalchemy, possibly wrapped up as a flask plugin https://flask-sqlalchemy.palletsprojects.com/ or more directly: https://www.sqlalchemy.org/

You can learn more about this approach and see an example is this Flask-SQLAlchemy PR.

Flask SQL Alchemy

I used for this project Flask and OpenAI CLIP. For the vector search I used approximate nearest neighbors provided by spotify/annoy. I used Flask-SQLAlchemy with GeoAlchemy2 to query GPS coordinates. The embedding was done using UMAP using the CLIP image vectors.

This appears to be this: https://github.com/pallets/flask-sqlalchemy/issues/910
