SQL-Ledger has this powerful audit log feature which records users actions (adding, editing, deletion transactions) in a database table named ‘audittrail’. Recently I had this requirement to log the transaction values into the audit table to see what has been changed. The solution I came out was to save the important column values as json in a new column formdata in the audittrail table. This new enhancements is now in testing phase with the help of a customer before it will be rolled out to all our hosting clients.

Next is to improve this code to add exception handling and also add the audit feature to the places in SQL-Ledger where it is not implemented like addition of customers and vendors and many such form.

In official SQL-Ledger, it is possible to add an invoice or a POS transaction without posting it and then forgetting to post it unintentional or sometimes, intentionally, by user to commit fraud.

I have made few changes in SQL-Ledger code which prevent this:

1. An invoice cannot be printed if it is not posted already.
2. As much invoice lines are printed as are already posted.

Here are these code changes which you can also do in your SQL-Ledger installation to achieve this.

I intend to make few more changes to avoid the situation where user makes some changes to the invoice, prints it and then skips posting it. I have marked this plan with TODO in these code diffs.

If you have any further ideas or queries on this topic, you can share them in comments.

We have recently updated our SQL-Ledger installation with latest version of Bootstrap (5.3.1 at the time of this writing), a popular CSS framework. It provides two major benefits:

• A modern application look and feel. No more complains from your users that SQL-Ledger design is old.
• Responsive behavior of forms and reports so that now SQL-Ledger works much better on mobile devices and tablets.

Since SQL-Ledger user interface is not template driven and is generated directly from Perl code, we had to make several changes to the code to generate html better suited for Bootstrap styles. But all this effort has paid off and our users are very happy with new look and feel.

Here are few screen shots after Bootstrap 5.3.1 upgrade:
