To manage different access rights for users in Odoo while ensuring specific permissions for each user or group, you can use Odoo's security groups and record rules. Here's how you can set this up:

Steps to Configure Access Rights:

1. Create or Modify User Groups:
   • Go to Settings > Users & Companies > Groups.
   • Create new groups or modify existing ones to define different levels of access. For example, you can create groups like "Sales Full Access" and "Sales View Only."
2. Define Access Control Lists (ACLs):
   • Access Control Lists define what actions users in a group can perform on various models.
   • Go to Settings > Technical > Security > Access Control Lists.
   • Create or modify records to set permissions for each group. For instance, you can set ACLs to allow creating, writing, and reading records but deny deletion for the "Sales Full Access" group.
3. Set Record Rules:
   • Record rules allow you to define what records users can access based on conditions.
   • Go to Settings > Technical > Security > Record Rules.
   • Create new rules to enforce specific access requirements. For instance, you can create a rule to restrict delete access for sales orders to users in the "Sales Full Access" group.

Example Configuration:

1. Create User Groups:

• Sales Full Access:
  • Users in this group can perform all actions except deletion in the sales module.
• Sales View Only:
  • Users in this group can only view sales orders but not create or edit them.
• Administrator:
  • Users in this group have full access to all modules and records.

2. Define ACLs:

• For "Sales Full Access":
  • Allow create, write, and read permissions on the sale.order model.
  • Deny delete permissions on the sale.order model.

• For "Sales View Only":
  • Allow read-only permissions on the sale.order model.

3. Set Record Rules:

• Prevent Deletion in Sales Orders for "Sales Full Access":

xmlCopy code
    Sales Orders - No Delete
    
    
    [('id', '!=', False)]
    

• Restrict Sales Orders Access to View Only for "Sales View Only":

xmlCopy code
    Sales Orders - View Only
    
    
    [('id', '!=', False)]
    
    
    
    

Apply the Changes:

• Update your module with these changes.
• Restart the Odoo server and update the module to apply the new permissions.

By following these steps, you can control access to specific functionalities in Odoo based on user groups, ensuring that each user has the appropriate level of access according to your requirements.
