Flask-Injector 0.1.0

Adds Injector support to Flask.

Adds Injector support to Flask.

Injector is a dependency-injection framework for Python, inspired by Guice.

Here’s a pseudo-example:

import sqlite3
from flask.ext.injector import Builder, route
from injector import inject

@route("/bar")
def bar():
    return render("bar.html")


# Route with injection
@route("/foo")
@inject(db=sqlite3.Connection)
def foo(db):
    users = db.execute('SELECT * FROM users').all()
    return render("foo.html")


# Class-based view with injection
@route('/waz')
class Waz(object):
    @inject(db=sqlite3.Connection)
    def __init__(self, db):
        self.db = db

    @route("/waz")
    def waz(self):
        users = db.execute('SELECT * FROM users').all()
        return 'waz'


def configure(binder):
    config = binder.injector.get(Config)
    binder.bind(
        sqlite3.Connection,
        to=sqlite3.Connection(config['DB_CONNECTION_STRING']),
        scope=request,
        )


def main():
    views = [foo, bar, Waz]
    modules = [configure]
    app = Builder(views, modules, config={
        'DB_CONNECTION_STRING': ':memory:',
        }).build()
    app.run()
