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.

Yesterday started as usual, planning new iteration, and then BAM! - one folk - Saif - joined the project. It made me correct the course a bit, and take care of potential contributors:

Yay! After implementing invalid data conversion, I finished the iteration #18 dedicated to diff-based migrations!
2 years ago ∙ 4 minutes read
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!

I continued working on property diff algorithm that plans all the migration details.

Yesterday, I finished implementing data conversion for int
and string
property types.
Then, I started refactoring it.

Last time, I pushed through string
property migrations and created a migration log.
Today, I continued solving data conversion issues.

string
property migrations.2 years ago ∙ 3 minutes 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.
2 years ago ∙ 3 minutes read
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.

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.

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.
2 years ago ∙ 3 minutes read
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.

It's often needed to compute, or index, data in database tables based on data in other tables.
This article is the first sketch of a consistent indexing solution.

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.

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

I had two very productive weeks. #buildinpublic works wonders.
Most effort went into my new project, Osm Admin. I sketched how data classes look like, generated database tables from class attributes, and started working on the Admin UI. It's very fulfilling to see how an abstract idea gains shape.

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.

I partly implemented data schema migration. It takes data class definitions, and incrementally creates or alters underlying database tables.
The article below describes how schema migration works, and what's not implemented yet, but most probably will be.
Note. This topic is continued in the new article.

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.

From now on, this website is deployed on push, and by the way, you can easily play with the website copy locally. In the Osm framework, new Osm_Project
application allows reflecting over modules and classes regardless to which application they belong. New experimental project is aimed at quick creation of the Admin UI.
