Hi,

The most probable reason your custom code isn't working in your new Odoo app, despite functioning in standard apps, is related to your Odoo hosting environment. If your Odoo database is hosted on Odoo Online (SaaS), it inherently restricts the installation and execution of custom modules containing code. This platform is designed for standard functionalities and does not permit third-party code to maintain system stability and security. To run custom code, you would need to migrate your database to either Odoo.sh (PaaS) or an On-Premise/Self-hosting setup, as these environments fully support custom module deployment.

Beyond the hosting environment, other factors could be at play. Ensure your custom property management app is correctly installed and activated within your Odoo database. It's also crucial to check your Odoo server logs for any specific error messages, as these can pinpoint syntax errors, dependency issues, or runtime exceptions in your code. Verify that your code is placed in the appropriate location within your module and that the actions you're performing are indeed designed to trigger that specific code. Finally, confirm that your module's __manifest__.py file accurately lists all necessary dependencies.

To help diagnose the issue more precisely, please specify where your Odoo database is hosted (e.g., Odoo Online, Odoo.sh, or on your own server) and which Odoo edition you are currently using (Community or Enterprise).
