How can I implement pagination in a Flask RESTful API?

You can use Flask-RESTful along with Flask-SQLAlchemy to implement pagination. Would you like a code example?

Yes, please provide a code example.

Sure! Here’s a simple example:

from flask import Flask, request
from flask_restful import Resource, Api, reqparse
from models import Item  # Assuming you have an Item model

app = Flask(__name__)
api = Api(app)

class ItemList(Resource):
    def get(self):
        page = request.args.get('page', 1, type=int)
        per_page = request.args.get('per_page', 10, type=int)
        items = Item.query.paginate(page, per_page, error_out=False)
        return {'items': [item.to_dict() for item in items.items], 'total': items.total}

api.add_resource(ItemList, '/items')

This will paginate your items based on the page and per_page query parameters.

What if I want to customize the response format?

You can customize the response by modifying the return statement. For example, you can include metadata like total pages or current page.
