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.

Osm Admin: Query Formulas

After 3 days of intensive work, I've got dot syntax working!

Along the way, I refactored the query internals once again, which reminds me a heuristics saying that you've got to implement something three times to get it right :)

New query implementation uses the concept of formulas - SQL-like expressions used for selecting, filtering and sorting data. Currently, formulas are quite limited, but with time, they should be a really powerful feature.

Osm Admin: Indexing (2)

Today, I implemented computation of indexed properties during insert. The implementation dictated some changes in indexed property definitions compare to the initial design, and how indexers are reflected into the data schema.

Also, I implemented a table query class working on the top of Laravel Query\Builder. More about it next time, for now I'll review how indexed properties are computed during INSERT operation.

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.

Osm Admin: Schema Hydration

I developed dehydrate()/hydrate() functions for a very practical need - storing the data class schema:

  • in cache - to reduce processing time spent on reflection;
  • and in database - to compare current and new database schema, and only add new tables and columns.

This article describes the information stored in the schema, and unit tests that I prepared in order to be sure that schema classes are property hydrated.

Osm Admin: Subclasses

As described in Migrations, most data objects of the same class will be stored in a database table.

But what about subclasses? In an e-commerce application, bags, dresses, and digital products, collectively known as subclasses, are all products stored in products table, and they may have bad-specific, dress-specific or digital product specific properties that should also be stored there.

This article describes how subclasses are defined and stored in Osm Admin.

This sprint was dedicated to writing Osm Framework documentation, and indeed, there are 8 new in-depth documentation articles, 4-5 minutes long each.

Despite documentation focus, I kept improving the website. From now on, you can assign a canonical URL to a blog post or a documentation page, and use GitHub friendly relative URLs in documentation.

But the most important thing - I started sharing progress and insights daily on Twitter.

osm.software website. From now on, Osm Framework documentation resides in the docs/ directory of the osmphp/framework repository, and it is displayed in a separate section of osm.software website. New data source indexing engine allows running complex interdependent data synchronization with a single command, osm index. New Placeholder class simplifies dynamic Markdown content generation.

Osm Framework. Apply dynamic traits within the same file using #[UseIn] attribute. Implement fast dynamic routing using new DynamicRoute class. Generate URLs using new $osm_app->base_url property.

This website got a completely new look. There are new blog posts diving into core Osm Framework features. Osm Framework itself offers more convenient page layout, website-wide header, footer and <head>, customizable error pages. The themes support theme-specific CSS styles and JS scripts not bound to any module. New projects come with a handy bin/install.sh script that simplifies installation on Linux. From now on, run osmh without any parameters.
