My flask application currently consists of a single test.py file with multiple routes and the main() route defined. Is there some way I could create a test2.py file that contains routes that were not handled in test.py?
@app.route('/somepath')
def somehandler():
# Handler code here
I am concerned that there are too many routes in test.py and would like to make it such that I can run python test.py, which will also pick up the routes on test.py as if it were part of the same file. What changes to I have to make in test.py and/or include in test2.py to get this to work?
You can use simple trick which is import flask app variable from main inside another file, like:
test-routes.py
from __main__ import app
@app.route('/test', methods=['GET'])
def test():
return 'it works!'
and in your main files, where you declared flask app, import test-routes, like:
app.py
from flask import Flask, request, abort
app = Flask(__name__)
# import declared routes
import test-routes
It works from my side.
I would like to recommend flask-empty at GitHub.
It provides an easy way to understand Blueprints, multiple views and extensions.
This task can be accomplished without blueprints and tricky imports using Centralized URL Map
app.py
import views
from flask import Flask
app = Flask(__name__)
app.add_url_rule('/', view_func=views.index)
app.add_url_rule('/other', view_func=views.other)
if __name__ == '__main__':
app.run(debug=True, use_reloader=True)
views.py
from flask import render_template
def index():
return render_template('index.html')
def other():
return render_template('other.html')
Dividing the app into blueprints is a great idea. However, if this isn't enough, and if you want to then divide the Blueprint itself into multiple py files, this is also possible using the regular Python module import system, and then looping through all the routes that get imported from the other files.
I created a Gist with the code for doing this:
https://gist.github.com/Jaza/61f879f577bc9d06029e
As far as I'm aware, this is the only feasible way to divide up a Blueprint at the moment. It's not possible to create "sub-blueprints" in Flask, although there's an issue open with a lot of discussion about this:
https://github.com/mitsuhiko/flask/issues/593
Also, even if it were possible (and it's probably do-able using some of the snippets from that issue thread), sub-blueprints may be too restrictive for your use case anyway - e.g. if you don't want all the routes in a sub-module to have the same URL sub-prefix.
