How can I implement file storage in a Flask application using a database?

You can use SQLAlchemy with Flask to manage file storage. First, create a model for your files.

What does the model look like?

The model can include fields like 'id', 'filename', 'filedata', and 'uploaded_at'. Here's a basic example.

How do I handle file uploads in Flask?

You can use Flask's request object to handle file uploads. Use request.files to access the uploaded files.

Can you show me a code snippet for that?

Sure! Here's a simple example:

from flask import Flask, request

@app.route('/upload', methods=['POST'])
def upload_file():
    if 'file' not in request.files:
        return 'No file part'
    file = request.files['file']
    # Save the file and store info in the database
