How can I configure Odoo 18.0 Enterprise model so that certain user groups have read-only access to records, while still permitting all users to post comments?


R3cord rules are blocking comments also 

Kindly advise

Hi,


To grant read-only access to records while allowing all users to post comments in Odoo 18.0 Enterprise, create a record rule that restricts write access for specific user groups on the desired model. Then, create a custom Odoo module and inherit the same model in a Python file. Override the message_post method, adding self.with_context(mail_create_nolog=True) before calling the super method.

This bypasses access rights checks specifically for creating comments, allowing users with read-only access to still post comments. Ensure your custom module depends on the mail module and thoroughly test the configuration to confirm that users can only access records as intended and can post comments.


Hope it helps

Hello Mohamed Hallal
I hope you are doing well

Use separate record rules for the model and the mail.message model:

  1. Create a read-only record rule for your model (e.g., sale.order):
  # Settings → Technical → Security → Record Rules
  Name: Sales Order - Read Only Group
  Model: Sales Order
  Groups: [Your Read-Only Group]
  Domain: [(1, '=', 1)]  # All records
  Permissions: Read ✓, Write ✗, Create ✗, Delete ✗
  2. Create a mail.message rule to allow commenting:
  Name: Allow Comments on Sales Orders
  Model: mail.message
  Groups: [Your Read-Only Group]
  Domain: [('model', '=', 'sale.order')]
  Permissions: Read ✓, Write ✓, Create ✓, Delete ✗

 Key Point: Even with read-only access on the main model, users need Create permission on mail.message to post comments in the chatter.

I hope this information helps you
