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.

Before diving into what should be in the docs, let's define what you should more or less know before using Osm Admin.
There are four types of people who will read the docs: power users, developers, vendors and contributors.

Here are my thoughts on product backlog and roadmap.

Implemented in Osm Admin:

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.

Yesterday, I moved the table creation code into new schema diff migration engine.
Now, working on notification table migrations.

Before digging into property diff algorithm, let's dig into how exactly it's used, and what other property-related logic is there.

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.

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.

In spirit of TDD, I started with a meaningful, but failing test that is reasonably fast. Then, I worked to make it green:

After drafting some ideas of how the schema migrations should actually work, let's start implementing it in TDD way.

The goal of the current iteration is to adjust the database schema and preserve/convert existing data according to any changes in schema classes, grids, forms or indexers.
This post presents some thoughts how it might work with class definitions.

After finishing the iteration "#17 Minimum UI", I revisited the goals and the scope of the minimum viable product, and picked the most pressing task for the next iteration - "#18 Database Schema Changes".

I implemented the last user action that is typical to a CRUD application - object deletion.

Done:
INSERT INTO ... SELECT ...

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.
Let's have a fresh look at Osm Admin. If I had to start from scratch, how would it be?

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.

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.

Today, I finished implementing an object creation form.
It works according to the specs on Interfaces and Forms. Currently, it only supports string and integer input fields; later, there will be a lot more.
Let's review how it works.

In Osm Admin, a form is an integral part of the class user interface. It's a very specific kind of HTML form.
In this article, I'll review what's in a class form, and how it's reflected from the application code.

Yesterday, I described a user interface pattern for managing data of a certain data class using a grid/form pair. Let's call this grid/form pair class interface in the admin
area.
In this article, I'll examine what moving parts are inside a class interface.

So far, I've been concerned about how application data is modeled, stored and handled internally.
Yet, the final objective a user interface for viewing and editing it visually.
Let's dream a bit about how it might look like.

Yay, indexing works!
It's changed quite a bit, so let's review how it works from the very beginning.

I'm still working on indexing, and it seems to get one more refactoring. But more on that later.
Meanwhile, let's review Osm Admin modules, their responsibilities and dependencies.

The project repository, osmphp/admin
, follows a typical Osm Framework-based project structure. However, this repository is going to be a reusable Composer package, and has important structural differences presented in this article.

I'm super-excited to announce that I'm starting a new project codenamed "The Big Red Button". It's about defining application data structures and logic in PHP code, pressing the big red button (hence the codename), and getting fully functioning Admin Panel and API.

After pushing changes to GitHub, osm.software website is updated without any additional manual action. On push, GitHub executes the deployment script on the production server. Most changes are done to content only, and in this case, the deployment script only updates the search index. Otherwise, with the website being on maintenance, it additionally updates Composer and Node dependencies, builds JS and CSS assets, and runs the database migrations.
