Install via Composer:

composer require sepehr-mohseni/elosql

The package will auto-register its service provider. Optionally, publish the configuration file:

php artisan vendor:publish --tag=elosql-config

Generate migrations and models for your entire database:

php artisan elosql:schema

See what will be generated without creating any files:

php artisan elosql:preview
php artisan elosql:migrations
php artisan elosql:models

The main command that generates both migrations and models.

php artisan elosql:schema [options]

Options:
  --connection=       Database connection to use (default: default connection)
  --table=            Generate for specific table(s), comma-separated
  --exclude=          Exclude specific table(s), comma-separated
  --migrations-path=  Custom path for migrations (default: database/migrations)
  --models-path=      Custom path for models (default: app/Models)
  --models-namespace= Custom namespace for models (default: App\Models)
  --no-migrations     Skip migration generation
  --no-models         Skip model generation
  --force             Overwrite existing files

Examples:

# Generate for specific tables
php artisan elosql:schema --table=users,posts,comments

# Exclude certain tables
php artisan elosql:schema --exclude=migrations,cache,sessions

# Custom output paths
php artisan elosql:schema --migrations-path=database/generated --models-path=app/Domain/Models

# Use a different database connection
php artisan elosql:schema --connection=legacy_db

Generate migration files from database schema.

php artisan elosql:migrations [options]

Options:
  --connection=   Database connection to use
  --table=        Generate for specific table(s)
  --exclude=      Exclude specific table(s)
  --path=         Custom output path
  --fresh         Generate fresh migrations (ignore existing)
  --diff          Only generate migrations for schema differences
  --force         Overwrite existing files

Examples:

# Generate migrations for a legacy database
php artisan elosql:migrations --connection=legacy --path=database/legacy-migrations

# Generate only new/changed tables
php artisan elosql:migrations --diff

Generate Eloquent model files.

php artisan elosql:models [options]

Options:
  --connection=   Database connection to use
  --table=        Generate for specific table(s)
  --exclude=      Exclude specific table(s)
  --path=         Custom output path
  --namespace=    Custom namespace
  --preview       Preview generated code without writing files
  --force         Overwrite existing files

Examples:

# Preview model generation
php artisan elosql:models --preview --table=users

# Generate with custom namespace
php artisan elosql:models --namespace="Domain\\User\\Models"

Preview the schema analysis without generating any files.

php artisan elosql:preview [options]

Options:
  --connection=   Database connection to use
  --table=        Preview specific table(s)
  --format=       Output format: table, json, yaml (default: table)

Examples:

php artisan elosql:preview --table=users

Show differences between database schema and existing migrations.

php artisan elosql:diff [options]

Options:
  --connection=   Database connection to use
  --format=       Output format: table, json (default: table)

After publishing the config file (config/elosql.php), you can customize:

'connection' => env('ELOSQL_CONNECTION', null), // null = default connection
'exclude_tables' => [
    'migrations',
    'failed_jobs',
    'password_resets',
    'personal_access_tokens',
    'cache',
    'sessions',
],
'migrations' => [
    'path' => database_path('migrations'),
    'separate_foreign_keys' => true, // Generate FK migrations separately
    'include_drop_tables' => true,   // Include down() method
],
'models' => [
    'path' => app_path('Models'),
    'namespace' => 'App\\Models',
    'base_class' => \Illuminate\Database\Eloquent\Model::class,
    'use_guarded' => false,           // Use $guarded instead of $fillable
    'generate_phpdoc' => true,        // Generate PHPDoc blocks
    'detect_soft_deletes' => true,    // Auto-detect SoftDeletes trait
    'detect_timestamps' => true,      // Auto-detect timestamp columns
],

Customize how database types map to Laravel migration methods:

'type_mappings' => [
    'mysql' => [
        'tinyint(1)' => 'boolean',
        'json' => 'json',
        // Add custom mappings
    ],
    'pgsql' => [
        'jsonb' => 'jsonb',
        'uuid' => 'uuid',
    ],
],
'relationships' => [
    'detect_belongs_to' => true,
    'detect_has_many' => true,
    'detect_has_one' => true,
    'detect_belongs_to_many' => true,
    'detect_morph' => true,
    'pivot_table_patterns' => [
        // Regex patterns for detecting pivot tables
        '/^([a-z]+)_([a-z]+)$/',
    ],
],
<?php

use Illuminate\Database\Migrations\Migration;

    }

    public function tags(): BelongsToMany
    {
        return $this->belongsToMany(Tag::class, 'post_tag');
    }
}

You can also use Elosql programmatically:

use Sepehr_Mohseni\Elosql\Parsers\SchemaParserFactory;
use Sepehr_Mohseni\Elosql\Generators\MigrationGenerator;
use Sepehr_Mohseni\Elosql\Generators\ModelGenerator;

// Get the parser for your database
$parser = app(SchemaParserFactory::class)->make('mysql');

// Parse all tables
$tables = $parser->getTables();

// Or parse specific tables
$tables = $parser->getTables([
    'include' => ['users', 'posts'],
    'exclude' => ['migrations'],
]);

// Generate migrations
$migrationGenerator = app(MigrationGenerator::class);
$files = $migrationGenerator->generateAll($tables, 'mysql', database_path('migrations'));

// Generate models
$modelGenerator = app(ModelGenerator::class);
foreach ($tables as $table) {
    $content = $modelGenerator->generate($table, 'mysql', $tables);
    // Write to file or process as needed
}

Elosql handles foreign key dependencies intelligently:

  1. Dependency Resolution – Tables are ordered based on their foreign key dependencies using topological sorting
  2. Separate FK Migrations – Foreign keys are generated in separate migration files that run after all tables are created
  3. Circular Dependencies – Detected and reported with suggestions for resolution

This ensures migrations can be run without foreign key constraint violations.

  • Integers: tinyint, smallint, mediumint, int, bigint

The Latest ‘Avengers: Doomsday’ Trailer Gives Us an Unlikely Team-Up

https://gizmodo.com/app/uploads/2026/01/avengers-doomsday-thing-fantastic-four-1280×853.jpg

It’s a Tuesday morning, and Avatar: Fire and Ash is still playing in theaters, so you know what that means: it’s time to sit down and watch a much nicer quality version of an Avengers: Doomsday trailer you already saw a camrip of on social media a week ago.

At least this time, whether or not you saw the leaks that have heralded every delayed online release rolling out Marvel’s Doomsday marketing plan, there is a surprisingly novel element to this latest one: it shows a new team-up for the latest entry in a superhero team-up movie. Imagine that!

The fourth Doomsday teaser jukes perhaps where many would’ve expected it to jive. After last week’s action-packed X-Men tease, things are back to a bit more of a calm, yet dire portent as we catch up with the worlds of Wakanda and Talokan after the events of Wakanda Forever. With Shuri mourning the loss of much of her family and Namor ever-vigilant for things that go bump in the ocean, it’s an intriguing figure we see when Shuri and M’Baku meet to disrupt that contemplation: none other than Ben Grimm of the Fantastic Four.

After their brief appearance arriving into the primary MCU timeline during Thunderbolts‘ post-credit scene, this is our first proper glimpse of the Fantastic Four joining up with the rest of the MCU, which is a fun little treat. It’s especially nice considering that Namor himself has a long history in the comics with the group, so even if he’s not present for this welcoming, it’s nice to at least put these two corners of the Marvel universe in each other’s paths like this.

But it’s also an intriguing choice for one of these teasers. The past three have focused on some big familiar heavy hitters making their comebacks for Doomsday—the “surprise” return of Chris Evans as Steve Rogers, another original Avenger (and Hollywood Chris) in Thor, and then of course the invocation of the Fox X-Men films. In contrast, this feels a bit more interestingly muted… and, of course, it continues to kick the can of whether or not one of these teasers will give us a proper look at Robert Downey Jr.’s Doctor Doom. At least we’re inching ever closer to that possibility with the arrival of a Fantastic Four member on the scene.

Time will tell if this is all we’ll be getting from Doomsday for now—early rumors about the campaign did say there would be just four teasers—or if we’ll be getting more as long as the box office is in a state of Pandora-induced mania. Either way, you’ll probably learn about it on social media first well before Marvel deigns to officially fill us all in.

Avengers: Doomsday hits theaters on December 18.

America Is Falling Out of Love With Pizza

The restaurant industry is trying to figure out whether America has hit peak pizza. From a report: Once the second-most common U.S. restaurant type, pizzerias are now outnumbered by coffee shops and Mexican food eateries, according to industry data. Sales growth at pizza restaurants has lagged behind the broader fast-food market for years, and the outlook ahead isn’t much brighter. "Pizza is disrupted right now," Ravi Thanawala, chief financial officer and North America president at Papa John’s International, said in an interview. "That’s what the consumer tells us." The parent of the Pieology Pizzeria chain filed for chapter 11 bankruptcy protection in December. Others, including the parent of Anthony’s Coal Fired Pizza & Wings and Bertucci’s Brick Oven Pizza & Pasta, earlier filed for bankruptcy. Pizza once was a novelty outside big U.S. cities, providing room for growth for independent shops and then chains such as Pizza Hut with its red roof dine-in restaurants. Purpose-made cardboard boxes and fleets of delivery drivers helped make pizza a takeout staple for those seeking low-stress meals. Today, pizza shops are engaged in price wars with one another and other kinds of fast food. Food-delivery apps have put a wider range of cuisines and options at Americans’ fingertips. And $20 a pie for a family can feel expensive compared with $5 fast-food deals, frozen pizzas or eating a home-cooked meal. […] Pizza’s dominance in American restaurant fare is declining, however. Among different cuisines, it ranked sixth in terms of U.S. sales in 2024 among restaurant chains, down from second place during the 1990s, Technomic said. The number of pizza restaurants in the U.S. hit a record high in 2019 and has declined since then, figures from the market-research firm Datassential show.

1000 Ants vs. an Obstacle Course

After seeing videos of how ant colonies work together, TerraGreen thought it would be interesting to see how they behave up close. So he gathered up roughly 1000 ants from an ant nest and put them to the test in a series of collaborative challenges and obstacle courses. Antony is quite the overachiever.

Logitech Caused Its Mice To Freak Out By Not Renewing a Certificate

An anonymous reader shares a report: If you’re among the macOS users experiencing some weird issues with your Logitech mouse, then good news: Logitech has now released a fix. This comes after multiple Reddit users reported yesterday that Logi Options Plus — the app required to manage and configure the controls on Logitech accessories — had stopped working, preventing them from using customized scrolling features, button actions, and gestures. One Reddit user said that the scroll directions and extra buttons on their Logitech mouse "were not working as I intended" and that the Logi Options Plus app became stuck in a boot loop upon opening it to identify the cause. Logitech has since acknowledged the situation and said that its G Hub app — a similar management software for gaming devices under the Logitech G brand — was also affected. According to Logitech’s support page, the problem was caused by "an expired certificate" required for the apps to run. Windows users were unaffected. The issues only impacted Mac users because macOS prevents certain applications from running if it doesn’t detect a valid Developer ID certificate, something that has affected other apps in the past.
