****************************
Interactive Python Shell
****************************
.. topic:: Introduction
This document describes how to setup the interactive, stateful Flex
shell that runs Python code on the server using the Flex_ SDK,
:doc:`Google App Engine<../gateways/appengine>` and
:doc:`Django <../gateways/django>`.
.. contents::
We recommend you **don't** run this example on a production server because
it exposes major security risks. This example is for educational purposes ;)
A live demo can be found on the PyAMF `Google App Engine example page`_.
Download
========
Clone the PyAMF repository with:
.. code-block:: bash
git clone git://github.com/hydralabs/pyamf.git pyamf
cd doc/tutorials/examples/actionscript/shell
Alternatively, if you just want to have a look, you can browse_ the example online.
Setup
=====
**Note**: make sure you have Django_ >= 1.0 installed.
Database
--------
This example uses SQLite_ to provide session support. First initialise the database by running:
.. code-block:: bash
python manage.py syncdb
Should output the following:
.. code-block:: bash
Creating table django_content_type
Creating table django_session
Gateway
=======
The remoting gateway for the Adobe Flash Player and Python AMF clients is available on
http://localhost:8000/gateway/shell/ when you launch the `development server`_:
.. code-block:: bash
python manage.py runserver
You should see something like:
.. code-block:: bash
Validating models...
0 errors found
Django version 1.1.1, using settings 'python.settings'
Development server is running at http://127.0.0.1:8000/
Quit the server with CONTROL-C.
Client
======
Flash Player
------------
You can simply open the `SWF file`_ and it will connect to http://localhost:8000.
.. image:: images/shellexample.png
Python
------
The Python AMF client can be started by running the following from the `python`
folder:
.. code-block:: bash
python client.py
You should see something like this for the client:
.. code-block:: python
Connecting to http://localhost:8000/gateway/shell/
Welcome to the PyAMF 0.5.1 Shell Demo!
Python 2.6.4 (r264:75706, Dec 22 2009, 21:55:52)
[GCC 4.2.1 (Apple Inc. build 5646)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>>
You can now use the interpreter as you normally would:
.. code-block:: python
>>> import sys
>>> sys.version
'2.6.4 (r264:75706, Dec 22 2009, 21:55:52) \n[GCC 4.2.1 (Apple Inc. build 5646)]'
Options
_______
When you run `python client.py --help` it will display the various options available
for this example client:
.. code-block:: bash
Usage: client.py [options]
Options:
-h, --help show this help message and exit
-p PORT, --port=PORT port number [default: 8000]
--host=HOST host address [default: localhost]
