Flask (A Python Micro Framework)
is a very promising so-called micro-framework for the development Python web applications. After installing mod_wsgi (See my previous post

installing mod_wsgi on Mac OS X 10.6

), is the use of Flask on Mac OS X no more obstacles. I go in the following assume that Python 2.6 and Python Setup Tools are already installed with MacPorts. Then you should

first The real easy-install-command select

> easy_install-2.6 Which

/ opt/local/bin/easy_install-2.6

second Flask install

> sudo easy_install-2.6 flask

third An example application Write:

> pico helloflask.py

import from flask Flask

app = Flask (__name__)

@app.route ("/")

def hello_flask ():

return "Hello Flask!"

if __name__ == "__main__":

app.run ()

> pico hello.wsgi

import sys

sys.path.append ("/ Users / username / Sites / webapp") from helloflask import app as application

4th Both files

hello.wsgi and helloflask.py

should be put in

/ Users / username / Sites / webapp

that the configured WSGIScriptAlias should be part of the Virtual Host

mydomain.org

(See Installation of mod_wsgi on Mac OS X 10.6 ).

5th mydomain.org call:

If everything went well we welcomed our first Flask Web application when calling
mydomain.org

in the browser with "Hello Flask!" .
