Flask views in separate module

If you want to move views to other file you need to register blueprint:

flask.py

# flaskr.py    
from flask import Flask
from .views import my_view

app = Flask(__name__)
app.register_blueprint(my_view)

if __name__ == "__main__":
    app.run()

views.py

# views.py
from flaskr import app
from flask import render_template, g

my_view = Blueprint('my_view', __name__)

@app.route('/')
def show_entries():
    entries = None
    return render_template('show_entries.html', entries=entries)

Similar questions:

• URL building with Flask and non-unique handler names
• Using flask/blueprint for some static pages

I solved this issue for me by adding a wilcard in flaskr.py. I saw this idea first at https://github.com/jennielees/flask-sqlalchemy-example, however I am now trying to do a blueprint as it is better to maintain the code in the long run I believe.

flaskr.py

# flaskr.py    
from flask import Flask

app = Flask(__name__)

# import views
from views import *

if __name__ == "__main__":
    app.run()

views.py

# views.py
from flaskr import app
from flask import render_template, g

@app.route('/')
def show_entries():
    entries = None
    return render_template('show_entries.html', entries=entries)

Apparently, this has to do with app.root_path.

• In views.py, app.root_path is /path/to/project/flaskr
• But in flaskr.py, app.root_path is /path/to/project

So Flask expects views.py to be put into a package.
