Odoo Orm API

Odoo ORM API

Goal

Manipulate data programmatically using the Odoo Object-Relational Mapping (ORM) API.

1. The Environment (self.env)

The environment stores the context, the cursor, and the user.

• self.env.user: The current user record.
• self.env.company: The current company record.
• self.env.context: A dictionary containing session data (lang, timezone, etc.).
• self.env.ref(xml_id): Get a record by its XML ID.

Modifying the Environment

Methods in Odoo models are executed with the current user's privileges. To change this:

• sudo(): Switch to the Superuser (bypass security rules).

  self.env['res.partner'].sudo().create({'name': 'Admin Contact'})
  

• with_context(**kwargs): Add or modify context keys.

  self.with_context(lang='fr_FR').name  # Translates name to French
  

• with_company(company): Switch the active company.

2. Searching Records

• search(domain, limit=None, offset=0, order=None): Returns a recordset.

  properties = self.env['estate.property'].search([
      ('state', '=', 'new'),
      ('expected_price', '<', 100000)
  ], limit=10)
  

• search_count(domain): Returns the number of records (integer).
• browse(ids): Returns a recordset from a list of IDs.

  property = self.env['estate.property'].browse([1, 2, 3])
  

• Domain: A list of tuples (field, operator, value).
  • Operators: =, !=, >, >=, <, <=, like, ilike, in, not in.
  • Logical: & (AND, default), | (OR), ! (NOT).

3. CRUD Operations

• create(vals_list): Create new records.

  # Single record
  new_prop = self.env['estate.property'].create({'name': 'New House', 'expected_price': 50000})
  # Multiple records (faster)
  props = self.env['estate.property'].create([{'name': 'H1'}, {'name': 'H2'}])
  

• write(vals): Update records.

  # Updates ALL records in the recordset 'properties'
  properties.write({'state': 'offer_received'})
  

• unlink(): Delete records.

  properties.unlink()
  

4. Exceptions

Use Odoo exceptions to stop execution and warn the user.

from odoo.exceptions import UserError, ValidationError

# Validations
if record.selling_price < record.expected_price * 0.9:
    raise ValidationError("Selling price cannot be lower than 90% of expected price.")

# User Warnings
if not record.partner_id:
    raise UserError("You must select a partner first.")

5. Mapped and Filtered

Optimization tools for recordsets.

• mapped(field_name): Returns a list of values (or recordset if method returns records).

  prices = properties.mapped('selling_price')
  partners = properties.mapped('partner_id') # Returns recordset
  

• filtered(func_or_field): Returns a subset of records.

  # Filter by field boolean value
  sold_props = properties.filtered('is_sold')
  # Filter by lambda
  expensive_props = properties.filtered(lambda p: p.expected_price > 500000)
