flasker 0.1.13


Latest Version: 0.1.45

Under development.

A Flask webapp project manager with built in ORM’ed database using SQLAlchemy and Celery backend support.

  • What Flasker is!

    • A transparent integration of Flask, SQLAlchemy and Celery which lets you configure these individually according to your project needs via a single .cfg file (cf. Sample config file).
    • A very simple pattern to organize your project via the current_project proxy. No more complicated import schemes!
    • OAuth (via Google OAuth 2) and a bunch of utilities via the util module (for convenient logging, efficient API responses, property caching, and more).
    • A command line tool from where you can create new projects, launch the Flask buit in Werkzeug server, start Celery workers and the Flower tool, and run a shell in the current project context (inspired by Flask-Script).
  • What Flasker isn’t?

    • A simplified version of Flask, SQLAlchemy and Celery. Flasker handles the setup but purposefully leaves you free to interact with the raw Flask, Celery and database objects. Some knowledge of these frameworks is therefore required.


  • Installation:

    $ pip install flasker
  • To create a new project:

    $ flasker new -a dev

    This will create a default project configuration file project.cfg in the current directory (the -a flag triggers the creation of a basic boostrap app).

  • Editing your project:

    The flasker module exposes a current_project proxy which grants you access to the Flask app, the Celery application and the SQLAlchemy database object respectively through its attributes app, celery, db. Inside each project module (defined in the MODULES option of the configuration file) you can then do, for example:

    from flasker import current_project
    app =
    # do stuff with the app
  • Next steps:

    $ flasker -h

    This will list all available commands for that project:

    • Running the app server
    • Starting a worker for the Celery backend
    • Running the flower worker management app
    • Starting a shell in the current project context (useful for debugging)

    Extra help is available for each command by typing:

    $ flasker <insert_command> -h

Sample config file

Here is a minimalistic project configuration file:

NAME: My Project
SHORTNAME: my_project
MODULES: app.views,app.tasks
DB_URL: sqlite:///db/db.sqlite
BROKER_URL: redis://localhost:6379/0

Using OAuth

To restrict access to your webapp to some users, you will need to enter your Google Client ID (from the Google API console) in the OAUTH_CLIENT configuration option and also enter authorized emails in the AUTHORIZED_EMAILS option. Then, use the login_required decorator from Flask-Login to protect your views (cf. the docs for examples and a tutorial). The callback URL you should authorize is http://your.domain:port/oauth2callback.



Other stuff

  • Setting up Redis:

    $ curl -O
    $ tar xvzf redis-stable.tar.gz
    $ cd redis-stable
    $ make
    $ make test
    $ sudo cp redis-server /usr/local/bin/
    $ sudo cp redis-cli /usr/local/bin/

    To daemonize redis on a mac:

    Create a plist file:

    $ sudo vim /Library/LaunchDaemons/io.redis.redis-server.plist

    Copy the following contents:

    <?xml version="1.0" encoding="UTF-8"?>
    <!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "">
    <plist version="1.0">
  • Running the server on Apache:

    Create a file called run.wsgi in the main directory with the following contents:

    # Virtualenv activation
    from os.path import abspath, dirname, join
    activate_this = abspath(join(dirname(__file__), 'venv/bin/'))
    execfile(activate_this, dict(__file__=activate_this))
    # Since the application isn't on the path
    import sys
    sys.path.insert(0, abspath(join(dirname(__file__)))
    # App factory
    from app import make_app
    application = make_app()

    Then add a virtualhost in your Apache virtual host configuration file (often found at /etc/apache2/extra/httpd-vhosts.conf) with the following configuration:

    <VirtualHost *:80>
      ServerName [server_name]
      WSGIDaemonProcess [process_name] user=[process_user] threads=5
      WSGIScriptAlias / [path_to_wsgi_file]
      <Directory [path_to_root_directory]>
          WSGIProcessGroup [process_name]
          WSGIApplicationGroup %{GLOBAL}
          Order deny,allow
          Allow from all
      ErrorLog "[path_to_error_log]"
      CustomLog "[path_to_access_log]" combined
