odoo_gateway 0.131

Version

0.0.1

Tech

To use Odoo Gateway properly you need only Odoo library of 7 or 8 versions.

Installation

You can use pip:

$ pip install odoo_gateway

Shell

Shell can be launched with:

$ odoosh [params]

Parameters are the same as openerp server’s ones. You can list then any time, just type:

$ odoosh --help

Ok, lets do it right now!:

$ odoosh -c config_file.conf -d database1

In [1]:

Nice! Odoo shell is launched now. Following objects are already in namespace:

• cr - Odoo wrapper for psycopg’s cursor:

  In [2]: cr
  <openerp.sql_db.Cursor at 0x3450d50>
  
  In [3]: cr.execute("select id, name from sale_order limit 1")
  In [4]: cr.fetchall()
  [(600094, u'SALE-123456')]``

• conn - Psycopg’s connection to database:

  In [5]: conn
  <connection object at 0x3485f60; dsn: 'host=localhost port=5432 user=odoo password=xxxx dbname=database1', closed: 0>
  In [6]: conn.rollback()

• rr - Psycopg’s cursor

• uid - Id of Odoo superuser

• conf - Instance of openerp.tools.config.configmanager that contains parsed Odoo parameters:

  In [7]: conf
  <openerp.tools.config.configmanager at 0x210bbd0>
  In [8]: conf['db_name']
  database1
  In [9]: conf['db_host']
  localhost

• models - Adapter for Odoo models’ list.:

  In [10]: models.sale_order  # get reference for model
  sale.order sale.order()
  In [11]: type(models.sale_order)
  openerp.api.sale.order
  In [12]: """Now we are free to apply API and user defined methods of model."""
  In [13]: sale1 = models.sale_order.search([('name','=', 'sale-111111')])
  In [14]: sale1.name sale-111111
  In [15]: sale2 = models['sale.order'].search([('name','=', 'sale-111112')])
  In [16]: sale2.name sale-111112

  There are two ways to refer to Odoo model.

• You can use model’s name name.of.model and get reference with models[name.of.model]. See line 15 of example above.

• Or you can replace ‘.’ with ‘_’ and type models.name_of_model. The result will be the same as in previous point. See lines 10-14.

• session - Instance of odoo_gateway.session.Session

Stand-alone scripts

There are problems which require using openerp API outside the openerp server, in another independent process. For example imagine that you have a Shop. Done? Ok. There is a python application APP. APP is a messenger and uses the system of queues. Customers send messages in which they describe what products they want to buy. APP gets messages from queues, parses them and create sale orders in database.

I belive that APP does not need for openerp server to be launched. No, sir!

All you need is instance of odoo_gateway.session.Session, which is initiated with odoo server’ command parameters.:

from odoo_gateway import Session
session = Session(['-c', 'config.conf', '-d', 'testdb'])

As you get session object you can get anything you may dream about.:

models = session.models
cr = session.cr
conn = session.conn
uid = session.uid
rr = session.rr
conf = session.conf

# The power is yours now

def create_sale(**params):
    models.sale_order.create(**params)
    cr.commit()
