Selection: Field stores text but the purpose is a selection
widget.
● selection: a list of tuple or a callable name that take
recordset as input
● size: the option size=1 is mandatory when using indexes
that are integers.
select = fields.Selection([('a', 'A')])
select = fields.Selection(selection=[('a', 'A')])
select = fields.Selection(selection='_function_name')](https://image.slidesharecdn.com/basicfieldsinodoo17-240402094801-2fd0298c/85/What-are-the-Basic-Fields-in-the-Odoo-17-ERP-14-320.jpg)

Selection_add: when you are trying to extend a model if you
want to add more possible values to an existing selection field
you may use the selection_add keyword argument:
class TestModel(models.Model):
_inherit = 'test.model'
type = fields.Selection(selection_add=[('b', 'B'),
('c', 'C')])](https://image.slidesharecdn.com/basicfieldsinodoo17-240402094801-2fd0298c/85/What-are-the-Basic-Fields-in-the-Odoo-17-ERP-15-320.jpg)

Reference: Store an arbitrary reference to a model and a row.
● selection: a list of tuple or a callable name that take
recordset as input.
refer = fields.Reference([('model.name','String_string')])
refer = fields.Reference(selection=[('model.name','String_string')])](https://image.slidesharecdn.com/basicfieldsinodoo17-240402094801-2fd0298c/85/What-are-the-Basic-Fields-in-the-Odoo-17-ERP-16-320.jpg)
What are the Basic Fields in the Odoo 17 ERP
- 1. Basic Fields in Odoo 17 Enterprise
- 2. Introduction Enterprise Odoo supports several fields for better data handling with specific options for each type. Some of the basic field in Odoo are Integers , float , char , Selection , Many2one, One2many ,Many2many , Date , Datetime etc...
- 3. Enterprise Types of Fields ● Simple Types ● Relation Types ● Functional Types
- 4. Enterprise ● Simple Types are Integer, Char, String, etc. ● Relation Types represent the relations between objects like Many2one, One2many, and Many2many. ● Functional fields are not stored in the database. They are special fields because the fields are calculated in real- time based on other fields of the view.
- 5. Enterprise Firstly, we need to import package fields. from odoo import models, fields For example:
- 6. Enterprise Boolean: Store boolean values True and False bool = fields.Boolean() bool = fields.Boolean(string="Active", default=True)
- 7. Enterprise Char: Store string or characters with length. ● Parameter: size: Data will be trimmed into the specified size. name = fields.Char() name = fields.Char(string="Name", required=True) proxy_ip = fields.Char(string='IP Address', size=45)
- 8. Enterprise Text: Used to store long texts. text = fields.Text() notes = fields.Text(string='Terms and Conditions')
- 9. Enterprise Integer: Fields to store integer values. Null value is not allowed. If there is no value then it returns zero. num = fields.Integer()
- 10. Enterprise Float: Used to store float values. Null value is not supported. If there is no value, it returns 0.0. ● Parameter: digits: it defines the precision and scale of the number. Scale is the number of digits after the decimal point and precision is the total number of significant digits in the number. float_num = fields.Float() amount = fields.Float(string="Amount", digits=(6, 2))
- 11. Enterprise Date: Date field stores date. The field has some helpers ● context_today: Returns current day date string based on timezone ● today: Returns current system date string ● from_string: Returns datetime.date() from string ● to_string: Returns date string from datetime.date today = fields.Date.today() fields.Date.context_today(self) fields.Date.context_today(self,timestamp=datetime.datetime.now()) fields.Date.from_string(fields.Date.today()) fields.Date.to_string(datetime.datetime.today())
- 12. Enterprise DateTime: It stores date and time in the same field. The field has some helpers. ● context_timestamp: Returns current day date string based on timezone ● now: Returns current system date string ● From_string: Returns datetime.date() from string ● to_string: Returns date string from datetime.date fields.Datetime.context_timestamp(self,timestamp=datetime.datetime.now() fields.Datetime.now() fields.Datetime.from_string(fields.Datetime.now()) fields.Datetime.to_string(datetime.datetime.now())
- 13. Enterprise Binary: field stores the encoded file in base64 in column bytea. file = fields.Binary()
- 14. Enterprise Selection: Field stores text but the purpose is a selection widget. ● selection: a list of tuple or a callable name that take recordset as input ● size: the option size=1 is mandatory when using indexes that are integers. select = fields.Selection([('a', 'A')]) select = fields.Selection(selection=[('a', 'A')]) select = fields.Selection(selection='_function_name')
- 15. Enterprise Selection_add: when you are trying to extend a model if you want to add more possible values to an existing selection field you may use the selection_add keyword argument: class TestModel(models.Model): _inherit = 'test.model' type = fields.Selection(selection_add=[('b', 'B'), ('c', 'C')])
- 16. Enterprise Reference: Store an arbitrary reference to a model and a row. ● selection: a list of tuple or a callable name that take recordset as input. refer = fields.Reference([('model.name','String_string')]) refer = fields.Reference(selection=[('model.name','String_string')])
- 17. Enterprise Html: Stores HTML and used as HTML Widget. html_wid = fields.Html()
- 18. Enterprise Many2one: Associates this object to a parent object via this field. ● comodel_name: name of the related model ● Delegate: if it is True, then it will make fields of the target model accessible from the current model. user = fields.Many2one('res.users') user = fields.Many2one(comodel_name='res.users') user = fields.Many2one(comodel_name='res.partner', delegate=True)
- 19. Enterprise One2many: Stores a relation against many rows of co-model ● comodel_name: name of the related model. ● inverse_name: the relational column of the related model. mod_ids = fields.One2many('res.users', 'rel_id') mod_ids = fields.One2many(comodel_name='res.users', inverse_name='rel_id')
- 20. Enterprise Many2many: Field stores multiple rows of a relation. ● comodel_name: name of the related model. ● relation: name of the relational table. ● columns1: left column name of the relational table. ● columns2: right column name of the relational table. mod_ids = fields.Many2many('res.partner’) mod_ids = fields.Many2many(comodel_name='res.partner', relation='table_name', column1='col_name', column2='other_col_name')
- 21. Enterprise The common parameters: ● help: Provide a description of how the field should be used. ● ondelete: To handle deletions in a related record. Values are: 'restrict', 'no action', 'cascade', 'set null', and 'set default'. ● readonly: If value = True, then the user cannot edit the field. ● required: The value of this argument is True, then the field can’t be empty before saving.
- 22. Enterprise ● size: The size of the field in the database can specify as a character or integer. ● string: Set label for the field. ● translate: If the value is True, then the content of the field should be translated. ● invisible: Hide fields from view if the value is 1. ● relation: Used to refer another table. Most commonly used in related and function field types. ● compute: used to call a function to get the value of the field. The value of the compute will be the name of a function
