I must say, it's a bit disturbing to implement the same thing for the third time. Still, the goal is to get it finished, and have it sustainable.
After the effort, the code has become su much easier to read!

Yesterday, I finished writing int
property migrations. True, testing it is still a todo.
The major part of the code (type change, nullability and other attribute handling) will be reused in other property types.

I refactored Property::migrate()
using additional Migration
classes. It's so much more convenient to compare property definition versions and generate migration SQLs!
New code structure already handles property explicitness changes.

This time, I tackled adding an explicit property to an existing table, and then making it non-nullable.
It raised the need for data conversions - additional handling of the existing data - or otherwise, the database engine fails, or the data becomes invalid.
And it made me split migrations in two parts - the one that runs before the data conversion, and the other one that runs afterwards.

After a system update, I've got some problem with my laptop, and one thing to check was system log files.
This got me thinking: what makes a good log for my own application? And I think that application logs are as useful as they are able to answer potential questions I may have when an application is in production.
Let's think what kind of questions I might have, and what information might be useful to answer them.

Recently, I fixed numerous issues to make the first migration tests work.
Then, I started implementing the schema diff algorithm - the basis for schema migrations.

More dots got connected in the schema migration design, see this post for details.
Then, I tried to return to TDDing it, but strange errors met me there, so I left them to be resolved in the next piece.
2 years ago ∙ 2 minutes read
Schema migrations are going to be generated and executed automatically under gulp watch
. It will result in lots of tiny migrations: add a column, change its type, make it not nullable, and so on.
It's convenient during development, but it might be not optimal to reapply in production. Indeed, it's better to convert a large table to new structure all at once rather than running a conversion for each of the tiny migration.
This observation contradicts the previously stated migration workflow, so let's update it.

A View
is a short-living object that is created and computed during page rendering. You can also create a pre-configured a View
object prototype in advance, and then clone it for rendering.
It's important not to execute render-time properties while configuring the prototype.
Use view()
helper function to create render-time view instances, and mark render-time properties using #[RenderTime]
attribute to prevent accessing them before rendering.

The implementation of the faceted implementation in osm.software
blog has shown that sometimes you need only facet counts, or only total count of matching entries.
Until now, Osm Framework had always queried total count
, ids
and facets
. Not anymore - and the search engine only provides the information that is actually needed.

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.

I decided to support selecting, filtering and ordering by properties of a related object using dot syntax: product.price
, parent.level
. This syntax will automatically join the table that stored related objects.
I realized that implementing joins requires a better query model than my current naive wrapper around Laravel query. This article describes the new query model.

This article is about running SELECT and INSERT queries on data objects stored in the database.
In short, use the query()
function. It runs on top of Laravel Query\Builder
. It handles the mapping of data class properties onto table columns, and initiates the computation of indexed properties.
Currently, you can only SELECT and INSERT, other operations are coming soon.

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've finished refactoring how Osm Admin stores data objects in the database. Also, in order to support multi-website, multi-vendor, multi-language applications, I've introduced the concept of scopes.
Most reasoning from the first version is still valid, so let's take a fresh look of what's changed.

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.

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.

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.

Different data classes have repeating structural patterns. For example, most data classes stored in database tables have the auto-incremented id
property. Use PHP traits to effectively introduce the same properties to different data classes over and over again.

In Osm Framework, an application is a set of modules that you run as a whole. There are several applications defined in the project, each having its own PHP class. Mostly, deal with the main one, Osm\App\App
. Beside the class name, every application also has a name, the main one is named Osm_App
.
Access the current application object, and the main parts of Osm Framework, via the global $osm_app
object and its properties. Add your own long-living objects there. Run an application using its HTTP or console entry point, or using Apps::run()
.

Modular software development is a well-known practice of dividing your application into several modules, each doing one thing, and doing it well. It increases readability and simplifies maintenance, as application concerns are fully separated from one another, easier to reason about, and to debug.
Modular development also encourages reuse. It's like a puzzle. Using one set of modules, you'll get an e-commerce application, using another set of modules - you'll get a blog application.
