Here's a breakdown of common field types in Odoo. This should help you understand the options available when defining your models. Odoo provides various field types for different data requirements, from basic text and numbers to complex relational fields connecting different models. Basic Field Types name = fields.Char(string='Name', required=True) # Char field (short text) description = fields.Text(string='Description') # Long text amount = fields.Float(string='Amount', digits=(10, 2)) # Decimal with precision quantity = fields.Integer(string='Quantity') # Whole number is_active = fields.Boolean(string='Active', default=True) # Checkbox (boolean) Date and Time Fields date_created = fields.Date(string='Created Date', default=fields.Date.today) # Date only datetime_modified = fields.Datetime(string='Modified DateTime') # Date + Time Selection Field state = fields.Selection([ ('draft', 'Draft'), ('confirmed', 'Confirmed'), ('done', 'Done') ], string='State', default='draft') # Predefined states Relational Fields partner_id = fields.Many2one('res.partner', string='Partner') # Link to single record line_ids = fields.One2many('example.line', 'example_id', string='Lines') # Link to multiple child records tag_ids = fields.Many2many('example.tag', string='Tags') # Many-to-many relationship
