Odoo Security Rules

Overview

Security in Odoo is managed at two levels: model-level access (who can read/write which models) and record-level rules (which records a user can see). This skill helps you write correct ir.model.access.csv entries and ir.rule domain-based record rules.

When to Use This Skill

• Setting up access rights for a new custom module.
• Restricting records so users only see their own data or their company's data.
• Debugging "Access Denied" or "You are not allowed to access" errors.
• Implementing multi-company record visibility rules.

How It Works

1. Activate: Mention @odoo-security-rules and describe the access scenario.
2. Generate: Get correct CSV access lines and XML record rules.
3. Debug: Paste an access error and get a diagnosis with the fix.

Examples

Example 1: ir.model.access.csv

id,name,model_id:id,group_id:id,perm_read,perm_write,perm_create,perm_unlink
access_hospital_patient_user,hospital.patient.user,model_hospital_patient,base.group_user,1,0,0,0
access_hospital_patient_manager,hospital.patient.manager,model_hospital_patient,base.group_erp_manager,1,1,1,1

Note: Use base.group_erp_manager for ERP managers, not base.group_system — that group is reserved for Odoo's technical superusers. Always create a custom group for module-specific manager roles:

<record id="group_hospital_manager" model="res.groups">
    <field name="name">Hospital Manager</field>
    <field name="category_id" ref="base.module_category_hidden"/>
</record>

Example 2: Record Rule — Users See Only Their Own Records

<record id="rule_hospital_patient_own" model="ir.rule">
    <field name="name">Hospital Patient: Own Records Only</field>
    <field name="model_id" ref="model_hospital_patient"/>
    <field name="domain_force">[('create_uid', '=', user.id)]</field>
    <field name="groups" eval="[(4, ref('base.group_user'))]"/>
    <field name="perm_read" eval="True"/>
    <field name="perm_write" eval="True"/>
    <field name="perm_create" eval="True"/>
    <field name="perm_unlink" eval="False"/>
</record>
