Row level security in postgreSQL
Does it work with Wappler or not?
If not then why?
Thank you
Wappler does not support RLS out of the box.
Here's what ChatGPT has to say. Looks like it might be possible, but would require some efforts on your part to ensure you're using custom queries and how to properly pass the user credentials.
Yes, you can use PostgreSQL's Row-Level Security (RLS) with Wappler. Since RLS is a database-level feature of PostgreSQL, it operates independently of the application layer. Wappler supports PostgreSQL as one of its database options, allowing you to build applications that interact with PostgreSQL databases.
Here are some considerations to ensure smooth integration:
- Database Connection Configuration:
- User Roles: RLS policies are enforced based on the database user role. In Wappler, make sure you're connecting to the database with the appropriate user credentials that RLS policies apply to.
- Dynamic Connections: If your application requires different users to have different access levels, consider implementing dynamic database connections in Wappler that use user-specific credentials.
- Setting Session Variables:
- RLS policies often rely on session variables to filter data per user. In Wappler, you can execute custom SQL queries or stored procedures upon establishing a database connection to set these variables.
- Example: Use a
SET
command in a custom query action to define the current user's context.
- Custom SQL Queries:
- When using custom queries in Wappler, ensure they align with your RLS policies.
- Avoid using superuser roles or bypassing RLS policies unintentionally through queries that elevate permissions.
- Testing:
- Thoroughly test your application to confirm that RLS policies are enforced as expected.
- Test with different user roles to ensure data is appropriately restricted.
- Error Handling:
- Be prepared to handle possible exceptions or errors that may arise due to RLS restrictions, such as
permission denied
errors when a user tries to access restricted data.
- Performance Considerations:
- While RLS adds a layer of security, it may have performance implications. Monitor query performance to ensure that RLS policies do not adversely affect your application's responsiveness.
Summary:
- Compatibility: Wappler is fully compatible with PostgreSQL and, by extension, supports RLS features.
- Implementation: Proper configuration is key. Ensure that your database connections, user roles, and session variables are set up to work with your RLS policies.
- Security Best Practices: Always adhere to security best practices by not exposing sensitive credentials and by validating user inputs.
By carefully configuring both your Wappler application and your PostgreSQL database, you can effectively utilize RLS to enhance the security of your application.
