2. Introduction Enterpr ise In Odoo, we can set a default value for a field during the creation of a record for a model. We have many methods in odoo for setting a default value to the field. 1. Passing Values Through Kwargs 2. Setting value with default_get function

3. Enterprise Passing Values Through Kwargs A field can have numerous kwargs specified, such as necessary, read-only, and many more. The Kwargs are special symbols used to pass arguments, known as keyword arguments. kwarg is the default, which aids in setting a field's default value at the moment a model is created.

11. Enterprise Setting value with default_get function To setting default values for custom fields using the default_get function in Odoo, you can define a method named default_get within your model class. This method should return a dictionary where the keys are the field names and the values are the default values you want to set.

12. Enterprise class SaleOrder(models.Model): _inherit = 'sale.order' sales_person_contact = fields.Many2one('res.partner', string="Salesperson Contact") sales_person_email = fields.Char(string="Salesperson Email") @api.model def default_get(self, fields): res = super(SaleOrder, self).default_get(fields) res.update({ 'sales_person_contact': self.env.user.partner_id.id or False, 'sales_person_email' : self.env.user.partner_id.email or False }) return res

13. Enterprise In this example, when a new record of SaleOrder is created, the default_get function will be called automatically, and it will return a dictionary containing default values for the specified fields (sales_person_contact and sales_person_email). These default values will be populated in the form when creating a new record unless overridden by the user. You can adjust the default values as per your requirements in the default_get method. This method allows you to dynamically set default values based on certain conditions if needed.
