Server Actions - Python Code, How do I import subprocess?

Hi All,

I'm trying to run a php script as a server action. I'm using the subprocess function of python to call the code. I have tested the code from the terminal and it works as expected. I've entered the same code into the server actions section (Action Type = Python code), and set the action in the workflow to run when a new order is confirmed. It doesn't work. The code is triggered at the right time, but openerp returns an error.

My code:


import subprocess

args = ["php", "/var/www/PH.php", "-f"]

subprocess.call(args)

It seems that i'm unable to import subprocess. Any idea's on how to do this?

Thanks in advance,

Tony.

In openerp/tools/safe_eval.py you can see a list of _SAFE_OPCODES, and IMPORT is not in it.  They also provide the variable __import__ which can only import _ALLOWED_MODULES.  However if you call the server action from some other method, you can include the modules that you need into context and pass it to the server action.  I believe it can be picked up during execution (eval).
