The document discusses connecting a Python application to OpenERP through the OOOP framework. It provides examples of how to connect to an OpenERP database using OOOP, perform CRUD operations on models like retrieving, filtering, creating, updating and deleting records, and working with related fields and objects. The document also lists some relevant URLs for OpenERP, OOOP and Launchpad.

2. ERP
Enterprise Resource Planning
Management / organization of our company
All company:
Customer

…
Custom management

3. OpenERP
ERP application client­server
Official modules: product, sale, account, stock,..
Extra modules: see addons­extra, addons­community
or other projects in Launchpad
OpenObject
Framework written by python

4. Client / GTK

5. Launchpad
Tool develop: code, bug, translations, blueprints, etc
Community work
OpenERP is develop community users
(behind this users are entreprises)
Other applications: MySQL, Ubuntu.... to 20241 projects!

6. OpenObject

7. MODULE STRUCTURE. Basic

8. MODULE STRUCTURE. All

9. MODEL. Name/Inherit
1. _name = 'model.model'
Create a database table: model_model
Examples:
res.partner = res_partner
res.partner.address = res_partner_address
product.product = product_product
2. _inherit = 'res,partner'
­ Add more fields or functions in other model exist.
­ Change functions or fields defined by other modules.

10. MODEL. Fields
1. _columns = {
2. 'name': fields.char('Name', size=100, required=True),
3. 'date_create': fields.date('Create', required=True),
4. 'date_expire': fields.function(_date_expire_days_get, method=True,
type="date", string="Date expired"),
5. 'partner_id': fields.many2one('res.partner', 'Partner', required=True),
6. 'active': fields.boolean('Active'),
7. 'field_ids': fields.one2many('model.other', 'model_id', string='Field'),
8. 'prod_ids':
fields.many2many('product.product','model_mod_rel','model_id',
'product_id','Products'),
9.}

11. MODEL. Default Values
1. _defaults = {
2. 'active': lambda *a: 1,
3. 'state': lambda *a: 'draft',
4. 'company_id': _default_company,
5. 'date': lambda *a:time.strftime('%Y­%m­%d'),
6. }

12. ORM Methods
Create Write Search Browse Unlink …
self.pool.get('res.users') + ORM()
1. self.pool.get('res.users').browse(cr, uid, id, context=context)
2. self.pool.get('res.company').search(cr, uid, [('parent_id', '=', False)])
3. self.pool.get('res.partner').create(cr, uid, {'name' : 'Zikzakmedia'} )
4. self.pool.get('res.partner').unlink(cr, uid, ids, context=context)

13. Functions
1. def _default_company(self, cr, uid, context={}):
2. user = self.pool.get('res.users').browse(cr, uid, uid, context=context)
3. if user.company_id:
4. return user.company_id.id
5. return self.pool.get('res.company').search(cr, uid, [('parent_id', '=',
False)])[0]
6. _defaults = {
7. 'active': lambda *a: 1,
8. 'company_id': _default_company,
9. }

14. OOOP
Connecting your Python App to OpenERP through OOOP
How to?

15. Connection
1. $ python
2. >>> from ooop import OOOP
3. >>> o = OOOP(user='user4', pwd='admin', dbname='user4',
uri='http://localhost', port=8070)
4. >>> from ooop import OOOP
5. >>> o = OOOP(dbname='demo') # Default values

16. All
1. $ python
2. >>> from ooop import OOOP
3. >>> o = OOOP(dbname='demo')
4. >>> partners = o.ResPartner.all()
5. >>> print partners[0]
6. <res.partner:2 'nou partner'> data instance
7. >>> print partners[0].name
8. Zikzakmedia
OpenObject | OOOP
res.partner | ResPartner

17. Get
1. $ python
2. >>> from ooop import OOOP
3. >>> o = OOOP(dbname='demo')
4. >>> n = o.ResPartner.get(1)
6. >>> print n.name
7. Zikzakmedia

9. Spain
10. >>> print n.country.id
11. 67

18. Delete / Deleting multiple records
1. $ python
2. >>> from ooop import OOOP
3. >>> o = OOOP(dbname='demo')
4. >>> n = o.ResPartner.get(1)
6. >>> n.delete()
1. $ python
2. >>> from ooop import OOOP
3. >>> o = OOOP(dbname='demo')
4. >>> n = o.ResPartner.all()
6. >>> n[1:100].delete()

19. Filtering
1. $ python
2. >>> from ooop import OOOP
3. >>> o = OOOP(dbname='demo')
4. >>> o.ResPartner.filter(name='Zikzakmedia')
5. >>> o.ResPartner.filter(name__ne='Zikzakmedia')
6. >>> o.ResPartner.filter(name__lt='Zikzakmedia')
7. >>> o.ResPartner.filter(name__lte='Zikzakmedia')
8. >>> o.ResPartner.filter(name__gt='Zikzakmedia')
9. >>> o.ResPartner.filter(name_gte='Zikzakmedia')
10. >>> o.ResPartner.filter(name__like='Zikzakmedia')
11. >>> o.ResPartner.filter(name_ilike='Zikzakmedia')
12. >>> o.ResPartner.filter(id_in=[1,2,5,7])
13. >>> o.ResPartner.filter(id_not_in=[1,2,5,7])

20. New
1. $ python
2. >>> from ooop import OOOP
3. >>> o = OOOP(dbname='demo')
4. >>> n = o.ResPartner.new()
5. >>> n.name = 'Partner created with OOOP'
5. >>> n.save()
1. $ python
2. >>> from ooop import OOOP
