I stopped working on the Osm Admin project, for financial reasons. Did it hurt? A lot. Was it necessary? Unfortunately, yes. This post is a short retrospection on this matter.

The goal is to be the most productive and focused on the most important things, both personally, and (later) as a team.
After maintaining the "done" log for several months, I decided to improve my estimation accuracy, and here is how.

There are four types of people who will read the docs: power users, developers, vendors and contributors.

After getting the main branch all-green (tests pass, CLI and UI works as expected), I decided that from now on, I'll keep it always green, and use feature branches for all major development.
Then, I started implementing the main menu of the admin area.

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.

After enumerating what kind of changes can happen to a property, I started implementing the most hard one - changing property type.

Estimating projects is hard. Here is my approach for getting better at it.
It's based on a concept of a "primitive problem" - something non-trivial that you can solve in one go.
You can use primitive problems as story points in agile project management.

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.

While working on diff algorithm I noticed a certain pattern that I use over an over again.
Using this pattern, I implemented notification table diff.
Finally, I rearranged diff/migration code for better code readability.

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.
2 years ago ∙ 1 minute read
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.

I came with an idea of much cleaner Osm Admin data class "markup", and more straightforward architecture, and I decided to give it a go in a separate experimental branch v0.2
, and to see if it's viable.
After three weeks of implementation effort, I can say that it is viable, and it's so much better! And it's not a completely new effort, I mostly copy code from v0.1
and some parts of osmphp/framework:old_v4
, and adapt it.
You can already define data classes using new markup, generate the database tables, and query it using new formula syntax. I really wanted to come with some UI working, but there wasn't enough time for that. It stays my priority for the next iteration.

My current goal is to get some minimum Osm Admin user interface and API working - just for one property, one data type, one UI control type, and then improve.
And there is a lot of space for improvement. The main areas are listed in this document.
I'd really appreciate a helping hand, so if you are into this sort of things, DM me on Twitter.

I feel that both attributes decorating data classes, and object model parsed from it are too complex.

Last two weeks were about implementing initial version of an Osm Admin grid, integrating it seamlessly with the editing form, and enabling mass-editing of multiple objects.
After finishing it, I realized that Osm Admin had become bigger than Osm Framework! To keep up, I started writing docs for it.
And now, you have a step-by-step guide for creating a project, adding Osm Admin to it and a practical example of an admin area that you can copy to your project and try it out locally.

Recently, I implemented mass-editing in Osm Admin. It allows you to view and edit multiple objects in a single operation.
This article describes mass-editing of products in a typical e-commerce application.

The last 4 weeks were mostly a vacation. It's been a time for reflection, but still, I delivered some new features.
In Osm Admin, forms already allow creating new objects and saving them to the database, and editing one or several existing objects.
I've also implemented URL query filters that are applied to the underlying database query and that can be displayed in the user interface.
From now on, Osm Framework and all projects built with it - can be installed and developed under Apache and on Windows.
2 years ago ∙ 3 minutes read
In the user interface, you can narrow displayed data using grid column filters, or filters displayed in the sidebar. To enable that, apply #[Filter\*]
attributes to class properties.
Applied filters appear in the URL query parameters, for example, .../edit?id=5+16+19
, and on the page.
You can apply filters not only to a grid page, but also to a form page - to mass edit all matching objects, or to an action URL (edit, delete, or custom) - to perform the action on all matching objects.
In the same way, you can apply filters to the API URLs in order to retrieve or modify matching objects in a script.

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:
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.
