Database Model Abstractions

In this video, we take a big step toward cleaner, more maintainable code by introducing a Model abstraction layer—a pattern that reduces boilerplate and centralizes logic around database operations. This lands in version v20-db-models.

Here’s what gets done:

✅ Create a Models/Photo class
- Move the all() and find() logic out of PhotoController and into this model

✅ Create a Models/Review class
- Same deal: centralize data logic away from controllers
- Introduce a protected static ?string $table property

🧱 Extract shared logic into a Framework/Model base class:
- static table() throws by default—models must define their own table
- Implement reusable all() and find() methods

🔄 Refactor all() and find() with:
- static::query() → creates an instance of the model
- get() → used by all(), calls build_query() to prepare the SQL and params
- build_query() → generates the SQL from query state

🧠 Reimagine find() usage like this:
- static::query()->where('id', '=', $id)->first();
- Then implement:
- A where() method that collects conditions into $wheres
- Modify build_query() to handle WHERE clauses
- A first() method to return the first matching result

🚀 Refactor the PhotoController to use the new model APIs
- Add an insert() method on the base Model class for creating new records


By the end of this refactor, your models are smart, reusable, and expressive—freeing your controllers from repetitive SQL and focusing them on application logic. Pragmatic PHP is feeling pretty elegant right about now. 👌

Database Seeding

In this episode, we build on our migrations work and dive into Laravel Database Seeding — a powerful feature that helps you automatically populate your database with meaningful test data.

Destructuring & Spread Syntax

Tired of writing extra lines just to pull out values or merge data? In this episode, you’ll learn two super-handy JavaScript features — destructuring and spread syntax — that make your code cleaner, shorter, and easier to read.

🎯 What you’ll learn:

Array destructuring — extract values directly into variables, skip items, and set default values.
Object destructuring — grab properties by name, rename them, and give them defaults.
Spread syntax — copy, merge, and expand arrays or objects with ease, plus collect the “rest” of the values.


💡 Why it matters:
These techniques are used constantly in modern JavaScript — especially in frameworks like React — so mastering them now will make your future projects smoother and more efficient.

By the end of this episode, you’ll be able to take apart and recombine data like a pro. 🚀

Displaying Reviews

Let’s bring feedback into the spotlight! In this video, we enhance the photo detail page by fetching and displaying user reviews from the database. 💬

Here’s what we’ll cover:


Query the database for all reviews associated with a given photo 📄
Loop through the reviews and display them on the photo page 🎞️
Calculate a summary (like average stars or total reviews) 📊
Display the summary alongside the photo for quick insight 🧠


By the end, version v15-show-reviews adds real voices to each photo—making the app feel more alive and interactive. 🚀

Dynamic Navigation

Now that we’ve extracted layout components, it’s time to make them truly dynamic! In this video, we’ll wire things up so our layout reacts intelligently to the current page. ⚡

Here’s what we’ll tackle:
• Use a $page_header variable in _header.view.php to set page-specific titles 🏷️
• Introduce a helpful dd() (dump and die) debugging function and place it in app/globals.php 🛠️
• Refactor _nav.view.php to highlight the active page using $_SERVER['REQUEST_URI'] 🎯

With these changes, our navigation becomes context-aware and our layout system becomes fully functional. This version is tagged as v4-functional-layout—a polished step forward! 🚀

Dynamic Photo Gallery

Time to showcase our images! In this video, we build a photo gallery page that lists all uploaded photos and links each one to its detailed view. 🧱

Here’s what we’ll do:


Create a new show.view.php by copying and modifying index.view.php 🧬
Add a new route and controller method to handle the gallery page 🗺️
Display all photos in a clean list or grid, each with a clickable link to its detailed photo page 🔗


With version v14-photos-list, our app now lets users browse through all uploaded images—laying the foundation for interactivity and exploration. 🚀

Dynamic Photo Page

Let’s make our photo pages come alive! In this video, we turn the static photo view into a fully dynamic experience by using the $_GET superglobal to load data based on query parameters. 🔍

Here’s what we tackle:


Update the PhotoController to read the id from $_GET and query the database accordingly
Show a 404 error if the id is missing or the record isn’t found 🛑
Improve our error views (404 and 500) by rendering them within the layout for a consistent look 🎨
Refactor the View class to default to the main layout (layout.app) while still allowing overrides
Fix a potential infinite render loop in the layout logic 🐛
Clean up unnecessary calls to ->layout() by relying on the new default behavior 🧼


By the end, version v13-photo-query-param will serve up the right photo with the right layout—dynamically and elegantly. 🚀

Eloquent ORM

In this episode, we move from raw query building into Laravel’s Eloquent ORM — an elegant way to interact with your database using PHP objects instead of SQL queries.
