Python CSV to OpenERP importation library

Project description

csv2oerp is a simple tool to perform a data migration, through an OpenERP mapping bounded to a CSV file. You can easily order your data as the manner of OpenERP (models, fields). The structure of the mapping is simple and intuitive, you can also perform a pre-process on data being imported, omit it or just modify it.

Quick start

Import csv2oerp and some callbacks:

>>> from csv2oerp import Import_session
>>> from csv2oerp.fields import Column, Custom, Relation
>>> from csv2oerp.callbacks import get_id, get_ids

Configure OpenERP connection:

>>> host = '198.168.0.1'
>>> port = 8069
>>> dbname = 'database'
>>> user = 'admin'
>>> pwd = 'admin'
>>> csv2oerp.connect(host, port, user, pwd, dbname)

Create a new importation instance:

>>> example_file = Import_session()

Set the CSV file to use:

>>> example_file.set_input_file('example_file.csv', ',', '"', 'utf-8')

Define a custom callback(Field’s value pre-treatment):

>>> def country_code(self, model, field, value, line):
...     """Return the first two uppered characters from current column value
...     """
...     return value[:2].upper()

Define your mapping to link both csv and OpenERP:

>>> mapping = {
...     # Define a base model (Always in list form)
...     'res.partner.address': [
...         {
...
...         # Custom field's value
...         'type':         Custom('default', search=True),
...
...         # Concatenated columns fields
...         'street':       Column([7, 6]),
...         'street2':      Column([8, 5]),
...
...         # Simple fields
...         'zip':          Column(9),
...         'city':         Column(10),
...         'cedex':        Column(68),
...         'phone':        Column(14),
...         'fax':          Column(15),
...         'email':        Column(17),
...
...         # Model's relation with dynamic insertion from OpenERP database
...         # Not native object from OpenERP framework
...         'region_id':    Custom(11, get_id('res.region', ['name']))
...         'dep_id':       Custom(12, get_id('res.dep', ['name']))
...
...         # Model's relations not updated if exists
...         'country_id':   Relation('REL_res_partner_address,NO_UPDATE::res.country'),
...
...         # Model's relations with unique value between objects
...         'partner_id':   Relation('REL_res_partner_address::res.partner', search=True),
...
...         },
...     ],
...
...     # Define relations between models
...     'REL_res_partner_address::res.partner': {
...         'name':         Column(1),
...         'siren':        Column(2),
...         'website':      Column(16),
...         'comment':      Column(56),
...         },
...
...     # Relation without write if exists
...     'REL_res_partner_address,NO_UPDATE::res.country':  {
...         'code':         Column(13, callback=_country_code, search=True),
...         'name':         Column(13, search=True),
...         },
...     })
>>> example_file.set_mapping(mapping)

Finally start the import process:

>>> example_file.start()

And show statistics of objects’s activities during the importation process:

>>> csv2oerp.show_stats()
