Odoo Code Snippets

Customization

Inherit or Modify a Search View —
<record id="account_invoice_search_extended" model="ir.ui.view">
    <field name="name">account.invoice.inherit.search</field>
    <field name="model">account.invoice</field>
    <field name="inherit_id" ref="account.view_account_invoice_filter"/>
    <field name="arch" type="xml">
        <xpath expr="//field[@name='number']" position="replace">
            <field name="number" string="Invoice" context="{'active_test': False}" filter_domain="['|','|','|','|',
            ('number','ilike',self), ('origin','ilike',self), ('reference', 'ilike', self), ('partner_id', 'child_of', self),
            ('invoice_line_ids.name','ilike',self)
            ]"/>
        </xpath>
    </field>
</record>
Create a Custom Model and Its View —
from odoo import models, fields, api, _
class Payroll(models.Model):
    _name = 'custom.payroll'
    _description = 'Payroll'

    name = fields.Char(string="Number", readonly=True, copy=False, default='New')

    state = fields.Selection([
        ('draft', 'Draft'),
        ('verify', 'Waiting'),
        ('done', 'Done'),
        ('cancel', 'Rejected'),
    ], string='Status', index=True, readonly=True, copy=False, default='draft')

    @api.model
    def create(self, vals):
        if vals.get('name', 'New') == 'New':
            vals['name'] = self.env['ir.sequence'].next_by_code('salary.number') or 'New'
        result = super(Payroll, self).create(vals)
        return result
Show Selection Field as Radio —
//set the widget property to radio
<field name="invoice_type" widget="radio"/>
Add Custom Fields to Product —
class ShopeeProduct(models.Model):
    _inherit = 'product.product'

    shopee_variation_id = fields.Char(string='Shopee Variation ID')

class ShopeeProductTemplate(models.Model):
    _inherit = 'product.template'

    shopee_product_id = fields.Char(string='Shopee Product ID')
Change User’s Default Page After Login —
Active developer mode under Settings
OpenSettings > Technical > User Interface > Menu Items.
Open on the Page you want to set as the landing page.
Change its Sequence to -1
Create a Wizard —
class SaleOrderWizard(models.TransientModel):
    _name = 'wizard.sale.order.download'

    def _default_orders(self):
        return self.env['sale.order'].browse(self._context.get('active_ids'))

    sale_ids = fields.Many2many('sale.order', string='Sales', default=_default_orders,
                                 auto_join=True, required=True, readonly=True)

    @api.multi
    def download_all(self):
        if self.sale_ids:
        	for sale in self.sale_ids:
        		# Do something here
Override a Model’s Create Update and Delete Methods —
class CustomModel(models.Model):
    _name='custom.model'    

    name = fields.Char(string='Document Name')

    @api.model
    def create(self, values):
        res = super(CustomModel,self).create(values)
        return res

    @api.multi
    def write(self, values):
        res = super(CustomModel, self).write(values)
        return res

    @api.multi
    def unlink(self, values):
        res = super(CustomModel, self).unlink()
        return res
