SSL(Self-Signed) Certificates are working fine on Firefox and Safari, but not on Chrome

Yesterday, I implemented self-signed SSL certificates to one of my websites, and to my surprise https link was working as expected on Safari and Firefox, but not on the Chrome browser. I was getting the following error:




With this, I connected with my IT team and come to know that, the certificates are not generated properly. All the browsers support different SSL expiry dates and we had to raise requests again to generate SSL Certificates for a minimum duration which was of 398 days (Apple) so that it can support all the browsers and new certificates worked without any issue.


Edit: 28-09-2020

Looks like all the Browser developers such as Google, Apple, Microsoft, and Mozilla have agreed to keep the SSL Certificate Lifespan common - 398 days. Please read more about it here:

Odoo: Qweb Templates Cache Issue

Hi Everyone, Today I was working on a hotel booking template in Odoo and changes made in the Qweb template(.xml) were not reflecting on updating module with odoo service restart. Tried few times without any success :(. Finally, I decided to delete the old template from Odoo backend and then update module again and it worked like a charm!! :) Steps to delete template from backend: Settings --> User Interface --> Views --> Search by template name Delete the used template. Although it's a small post, but I'm sure it will meet the purpose and help someone in the future. Thanks!!!

Odoo/OpenERP: one2one relational field example

one2one relational field is deprecated in OpenERP version>5 but you can achieve the same using many2one relational field.
