In your Odoo custom module, create a security folder and add a file named ir.model.access.csv. This file is required to manage access rights for the model.

Structure of ir.model.access.csv

• id: A unique identifier for the access record.
• name: A descriptive name for the access record.
• model_id:id: The technical name of the model for which access rights are being defined.
• group_id:id (optional): The group to which access is granted. Leave this field empty to provide access to all groups.
• perm_read, perm_write, perm_create, perm_unlink: Permissions for Read, Write, Create, and Delete operations, represented as 1 (enabled) or 0 (disabled).

Example ir.model.access.csv File

csv

id,name,model_id:id,group_id:id,perm_read,perm_write,perm_create,perm_unlink
access_sale_order_discount_wizard,Sale Order Discount Wizard,model_sale_order_discount_wizard,,1,1,1,1

Explanation of the Example

1. id: access_sale_order_discount_wizard – A unique identifier for this access control record.
2. name: Sale Order Discount Wizard – The name of the access control record.
3. model_id:id: model_sale_order_discount_wizard – The technical model name for which the access control is applied.
4. group_id:id: Left empty to allow access to all groups.
5. perm_read, perm_write, perm_create, perm_unlink: All permissions are set to 1 (enabled), meaning users have full access to this model.

Steps to Apply Access Rights

1. Create a security folder in your module if it doesn’t already exist.
2. Add the ir.model.access.csv file with the appropriate content as shown above.

Update the __manifest__.py file to include the security file under the data key:
python

‘data’: [

    ‘security/ir.model.access.csv’,

],

Upgrade your module to apply the changes:
bash

./odoo-bin -u <module_name>

This ensures your model has the proper access rights configured in Odoo.
