Question

I’m new to OpenERP and Python, I’m trying to understand the various functions in the py files. There is an import function used in all files generally devided into two parts : the first part seems to refer to Python librairies (called modules ?) like from datetime import datetime or from dateutil.relativedelta import relativedelta but the second part, I don’t know what it refers to.

I would like to know what the following functions refer to :

import netsvc
import pooler
from osv import fields, osv
import decimal_precision as dp
from tools.translate import _

What is netsvc, pooler, osv, decimal_precision, tools_translate ? If they are openERP modules, where can I find the code behind them, else what are they ?

I would be grateful to anyone who would be able to explain to me all of them, and any other similar ones if he/she knows of any.

It sounds like you have installed some version of OpenERP that includes compiled files instead of the raw Python source code.

I suggest you reconfigure your development environment by checking the source out from launchpad and running the server from the source code. Personally, I like to run it under Eclipse with PyDev, because it has a nice debugger.

For the project configuration in Eclipse, I just checked out each branch from launchpad, and then imported each one as a project into my Eclipse workspace. The launch details are a bit different between 6.0 and 6.1. Here are my command line arguments for launching each version of the server project:

6.0:

–addons-path ${workspace_loc:openerp-addons-6.0} –config ${workspace_loc:openerp-config/src/server.config} –xmlrpc-port=9069 –netrpc-port=9070 –xmlrpcs-port=9071

6.1 needs the web client to launch with the server:

–addons-path ${workspace_loc:openerp-addons-trunk},${workspace_loc:openerp-web-trunk}/addons,${workspace_loc:openerp-migration} –config ${workspace_loc:openerp-config/src/server.config} –xmlrpc-port=9069 –netrpc-port=9070 –xmlrpcs-port=9071
