In Osm Admin, I've finished indexing. It means that whenever you modify an object in the database, the changes are automatically propagated to all dependent indexed properties in the database.

I've also introduced a grid/form pair as the main user interface concept that is optimized for performing operations on multiple objects. There is also a programming interface (API) that will internally work in the same way, but without visuals. I implemented a part of this interface - an object creation form.

Osm Framework and all projects built with it - including this website and Osm Admin - are upgraded to TailwindCSS 3.0.

For the last two weeks, I figured out two core features that will allow Osm Admin to stand out from other CRUD applications:

  1. It will allow mass editing of data objects.
  2. It will automatically propagate data changes throughout the database.

The foundation for the mass editing feature is data queries. Data propagation will be ensured via indexing.

I've been working on the Osm Admin indexing engine, and it's still in progress. While working on it, I reworked the inner working of data queries. Finally, I've achieved a very clear separation of various Osm Admin concerns, and documented it.

In Osm Core, I added reflection over class methods.

I had two weeks full of meaningful, productive work. I started with sketching Osm Admin grid and form pages, and implemented a very basic, but working home page, and success/error messages. To enable that, Osm Framework now have extensible Blade templates, and a nice JavaScript solution for capturing user input into a modal dialog box, or into some picker component.

Then, I undertook a major refactoring of Osm Admin, including moving lots of pieces of code to their new places, stabilizing the underlying object model, rewriting database migrations and sketching future effort on data indexing. During this effort, I implemented generic object hydration and reflection over named subtypes.

I've already shared most of this information on Twitter, so if you are reading this, consider following me on Twitter and getting daily updates.

Framework: Hydration

Recently, I developed a couple of helper functions for transmitting PHP objects over the wire, and saving them in database records:

  • dehydrate() - recursively converts an instance of a PHP class to a plain untyped object. Then, store the plain object in the database, or convert it to JSON and send it to a browser.
  • hydrate() - recursively converts a plain untyped object back to a PHP class instance. Use if after decoding a JSON received from the browser, or after loading a database record.

This article describes how to use these functions.

Framework: Modal Elements

When active, modal elements - dialogs, pickers, or AJAX spinners - need to prevent user interaction with the rest of the page.

A common approach is putting an overlay <div> under the modal element covering the rest of the page, as a click shield. However, user can still navigate the page with the keyboard.

Today, I implemented a better solution by capturing mouse and keyboard events outside the modal element, and keeping focus inside.
