stacked_permissions

Stacked Permissions adds a new way to assign permissions to users — outside of roles — by using permission groups that "stack" directly onto user accounts.

This is ideal for organizations needing more granular or situational permission control than roles can provide.

Features

• Define Permission Groups with selected permissions.
• Assign users to those groups.
• Users receive permissions from:
• Their roles
• PLUS any Permission Groups they belong to.
• Admin interface for:
• Defining "allowed permissions" (what groups are allowed to grant)
• Managing group membership
• View integration:
• Display a user’s permission groups
• Add tabs to user profiles

Configuration Steps

Set Allowed Permissions
Go to: /admin/config/people/stacked-permissions/allowed

• Choose which permissions are available to groups
• Only those permissions can be granted in groups

Create a Permission Group
Go to: /admin/content/permission-group/add

• Give it a name
• Assign permissions (from the allowed list)
• Add users to the group

User Permissions Now Stack
Users receive:

• Standard role permissions
• PLUS permissions from any permission groups they belong to

User Profile Tab
The module includes a view:
/user/{uid}/assigned-permission-groups

This appears as a tab on user profiles (next to View / Edit) and shows:

• Groups the user belongs to
• Permissions granted via groups

This tab is automatically added when the module is installed.

Developer Notes

• Permission group logic wraps Drupal’s AccountInterface::hasPermission() using a proxy.
• Custom entity types:
• permission_group
• permission_group_membership
• Fully compatible with user role permissions

Example Use Cases

• Assign "Editor" permissions to a specific user without changing their role
• Create temporary groups for event-based permissions
• Manage permissions across departments without changing global roles

Similar projects

• Group: broader group content ownership
• Role Assign: simpler UI for role management
• Permissions by Term: restrict access based on taxonomy
