flask and learning blueprint condos7 installation python3

One

flask blueprint for action: implement the modular routing flask

Instructions:

Create a blueprint in the routing of the newly created admin:

from flask import Blueprint

admin = Blueprint('admin',__name__)


@admin.route('/')
def admin_home():
    return 'admin_home'

Then newly registered blueprint app.py import and register the app

from flask import Flask
from admin.views import admin
from user.views import user

app = Flask(__name__)


app.register_blueprint(admin, url_prefix="/admin")
app.register_blueprint(user, url_prefix="/user")


@app.route('/')
def hello_world():
    return 'Hello World!'


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

After the access port address plus / admin will then return a admin_home example: http://127.0.0.1:5000/admin/
