Odoo Model Development

Basic Model Template

from odoo import models, fields, api
from odoo.exceptions import ValidationError, UserError

class ModelName(models.Model):
    _name = 'module.model'
    _description = 'Model Description'
    _inherit = ['mail.thread', 'mail.activity.mixin']  # For chatter
    _order = 'create_date desc'

    # Basic Fields
    name = fields.Char(
        string='Name',
        required=True,
        index=True,
        tracking=True  # Track changes in chatter
    )

    active = fields.Boolean(default=True)

    # Relational Fields
    partner_id = fields.Many2one(
        'res.partner',
        string='Customer',
       
        required=True
    )

    line_ids = fields.One2many(
        'module.model.line',
        'parent_id',
        string='Lines'
    )

    tag_ids = fields.Many2many(
        'module.tag',
        string='Tags'
    )

    # Selection Field
    state = fields.Selection([
        ('draft', 'Draft'),
        ('confirmed', 'Confirmed'),
        ('done', 'Done'),
        ('cancelled', 'Cancelled')
    ], default='draft', tracking=True)

    # Computed Fields
    total_amount = fields.Float(
        string='Total',
        compute='_compute_total_amount',
        store=True  # Store in database for performance
    )

    @api.depends('line_ids.amount')
    def _compute_total_amount(self):
        for record in self:
            record.total_amount = sum(record.line_ids.mapped('amount'))

    # Constraints
    @api.constrains('amount')
    def _check_amount(self):
        for record in self:
            if record.amount < 0:
                raise ValidationError("Amount must be positive")

    # Onchange Methods
    @api.onchange('partner_id')
    def _onchange_partner_id(self):
        if self.partner_id:
            self.email = self.partner_id.email

    # CRUD Override
    @api.model
    def create(self, vals):
        # Add logic before creation
        if not vals.get('name'):
            vals['name'] = self.env['ir.sequence'].next_by_code('module.model')
        return super().create(vals)

    def write(self, vals):
        # Add logic before update
        return super().write(vals)

    def unlink(self):
        # Add logic before deletion
        if any(rec.state == 'done' for rec in self):
            raise UserError("Cannot delete confirmed records")
        return super().unlink()

    # Business Methods
    def action_confirm(self):
        self.ensure_one()
        self.state = 'confirmed'
        self.message_post(body="Record confirmed")

    def action_cancel(self):
        self.write({'state': 'cancelled'})

Advanced ORM Patterns

Search Domains

# Simple search
records = self.env['res.partner'].search([('name', 'like', 'Odoo')])

# Complex search with operators
records = self.env['sale.order'].search([
    '|',  # OR operator
        ('state', '=', 'sale'),
        ('state', '=', 'done'),
    ('amount_total', '>', 1000),
    ('partner_id.country_id.code', '=', 'US')
], limit=10, order='date_order desc')

# Search count
count = self.env['product.product'].search_count([('active', '=', True)])

Recordset Operations

# Filtering
active_partners = partners.filtered(lambda p: p.active)

# Mapping
names = partners.mapped('name')
emails = partners.mapped('child_ids.email')

# Sorting
sorted_orders = orders.sorted(key=lambda o: o.amount_total, reverse=True)

# Grouping
grouped = products.read_group(
    [('categ_id', '!=', False)],
    ['categ_id', 'qty_available:sum'],
    ['categ_id']
)

Common Odoo Patterns

Inheritance Patterns

Classical Inheritance (_inherit with _name)

class ResPartner(models.Model):
    _name = 'res.partner'
    _inherit = 'res.partner'

    custom_field = fields.Char('Custom Field')

Prototype Inheritance (_inherit without _name)

class SaleOrder(models.Model):
    _inherit = 'sale.order'

    custom_field = fields.Char('Custom Field')

Delegation Inheritance (_inherits)

class ResUsers(models.Model):
    _name = 'res.users'
    _inherits = {'res.partner': 'partner_id'}

    partner_id = fields.Many2one('res.partner', required=True)

Wizards (Transient Models)

class CustomWizard(models.TransientModel):
    _name = 'module.wizard'
    _description = 'Custom Wizard'

    date_from = fields.Date(required=True)
    date_to = fields.Date(required=True)

    def action_generate_report(self):
        self.ensure_one()
        # Wizard logic
        active_ids = self.env.context.get('active_ids')
        records = self.env['sale.order'].browse(active_ids)
        # Process records
        return {
            'type': 'ir.actions.act_window',
            'res_model': 'module.report',
            'view_mode': 'tree,form',
            'domain': [('date', '>=', self.date_from)],
        }

Scheduled Actions

class CustomModel(models.Model):
    _name = 'module.model'

    @api.model
    def _cron_cleanup_old_records(self):
        """Scheduled action to cleanup old records"""
        cutoff_date = fields.Date.today() - timedelta(days=90)
        old_records = self.search([('create_date', '<', cutoff_date)])
        old_records.unlink()

Server Actions (XML)

<record id="action_auto_confirm" model="ir.actions.server">
    <field name="name">Auto Confirm Orders</field>
    <field name="model_id" ref="model_sale_order"/>
    <field name="state">code</field>
    <field name="code">
        for record in records:
            record.action_confirm()
    </field>
</record>

JavaScript (OWL Framework - Odoo 17+)

Basic Component

/** @odoo-module **/

import { Component } from "@odoo/owl";
import { registry } from "@web/core/registry";

class CustomWidget extends Component {
    static template = "module.CustomWidget";
    static props = ["*"];

    setup() {
        // Component setup
    }

    onClick() {
        // Handle click
    }
}

registry.category("fields").add("custom_widget", CustomWidget);

Reports (QWeb)

Report Template

<template id="report_custom_document">
    <t t-call="web.html_container">
        <t t-foreach="docs" t-as="o">
            <t t-call="web.external_layout">
                <div class="page">
                    <h2><span t-field="o.name"/></h2>
                    <table class="table">
                        <thead>
                            <tr>
                                <th>Product</th>
                                <th>Quantity</th>
                                <th>Price</th>
                            </tr>
                        </thead>
                        <tbody>
                            <tr t-foreach="o.line_ids" t-as="line">
                                <td><span t-field="line.product_id.name"/></td>
                                <td><span t-field="line.quantity"/></td>
                                <td><span t-field="line.price_unit"/></td>
                            </tr>
                        </tbody>
                    </table>
                </div>
            </t>
        </t>
    </t>
</template>

Best Practices

Performance

1. Use store=True for computed fields used in searches/filters
2. Add indexes on frequently searched fields: index=True
3. Batch operations: Use self.env.cr.execute() for bulk updates
4. Avoid N+1 queries: Use mapped() instead of loops
5. Prefetch records: Use with_context(prefetch_fields=False) sparingly

Security

1. Always use record rules for row-level security
2. Validate user inputs in constraints and compute methods
3. Use sudo() carefully - only when necessary
4. Check access rights before sensitive operations
5. Log important actions using message_post()

Code Quality

1. Use self.ensure_one() for methods expecting single record
2. Follow naming conventions: snake_case for Python, CamelCase for classes
3. Add docstrings to methods and classes
4. Use context appropriately: with_context(), with_company()
5. Handle exceptions gracefully: Use UserError for user-facing errors

Module Design

1. Small, focused modules over monolithic ones
2. Clear dependencies in __manifest__.py
3. Proper upgrade path using migrations
4. Demo data for testing and examples
5. Proper translations using _() function

Common Issues & Solutions

Issue: Field not showing in view

• Check field is in model
• Verify field name spelling
• Check view inheritance order
• Clear browser cache and reload

Issue: Access denied errors

• Check ir.model.access.csv permissions
• Verify record rule domains
• Check user groups assignment
• Use sudo() if needed (with caution)

Issue: Compute field not updating

• Verify @api.depends() decorator
• Check if dependent fields are stored
• Use store=True if needed
• Trigger recomputation manually if needed

Issue: Translation not working

• Generate .pot file: odoo-bin -d dbname --i18n-export=module.pot
• Import translations: odoo-bin -d dbname --i18n-import=fr.po -l fr_FR
• Clear cache after translation update

Development Workflow

1. Create module structure: Use scaffold or manual creation
2. Define models: Start with basic fields, add complexity iteratively
3. Create views: Form → Tree → Search → Kanban
4. Add security: Access rights and record rules
5. Test functionality: Use demo data, create test cases
6. Add business logic: Constraints, compute fields, methods
7. Optimize: Add indexes, store computed fields, batch operations
8. Document: Docstrings, help text on fields, module description
