2/18/2024 0 Comments Flask blueprint no module namedWe can also add path operations directly to the FastAPI app. In the init.py file, we will create a Flask app and register our blueprints there: from flask import Flask app Flask(name) from. So, for example, other projects could use the same APIRouter with a different authentication method. The result is that in our app, each of the path operations from the admin module will have:īut that will only affect that APIRouter in our app, not in any other code that uses it. That way, the original APIRouter will keep unmodified, so we can still share that same app/internal/admin.py file with other projects in the organization. dependencies import get_token_header router = APIRouter ( prefix = "/items", tags =, dependencies =, responses = You import it and create an "instance" the same way you would with the class FastAPI:įrom fastapi import APIRouter, Depends, HTTPException from. The environment variables for flask must be set as of flask 1.1.x. This is what registers a flask.blueprint to the Flask app. Blueprints can greatly simplify how large applications work and provide a central means for Flask extensions to register. an AppPlugin object must be available and inherited by the Plugin's class. You can create the path operations for that module using APIRouter. Flask uses a concept of blueprints for making application components and supporting common patterns within an application or across applications. You want to have the path operations related to your users separated from the rest of the code, to keep it organized.īut it's still part of the same FastAPI application/web API (it's part of the same "Python Package"). If you're not sure which to choose, learn more about installing packages.
