📖 Summary

Automatic, self-invalidating Eloquent model and relationship caching. Add a trait to your models and all query results are cached automatically — no manual cache keys, no forgetting to invalidate. When a model is created, updated, or deleted the relevant cache entries are flushed for you.

⚡ Typical performance improvements range from 100–900% reduction in database queries on read-heavy pages. 🧪 Backed by 335+ integration tests across PHP 8.2–8.5 and Laravel 11–13.

Use this package when your application makes many repeated Eloquent queries and you want a drop-in caching layer that stays in sync with your data without any manual bookkeeping.

🔄 Before & After

❌ Without this package — manual cache keys, manual invalidation:

$posts = Cache::remember('posts:active:page:1', 3600, function () {
    return Post::where('active', true)->with('comments')->paginate();
});

// And in every observer or event listener…
Cache::forget('posts:active:page:1');
// Hope you remembered every key variant! 😅

✅ With this package — add the trait, query normally:

// Just query. Caching and invalidation happen automatically. ✨
$posts = Post::where('active', true)->with('comments')->paginate();

✅ What Gets Cached

Model queries (get, first, find, all, paginate, pluck, value, exists)
Aggregations (count, sum, avg, min, max)
Eager-loaded relationships (via with())

🚫 What Does Not Get Cached

Lazy-loaded relationships — only eager-loaded (with()) relationships are cached. Use with() to benefit from caching.
Queries using select() clauses — custom column selections bypass the cache.
Queries inside transactions — cache is not automatically flushed when a transaction commits; call flushCache() manually if needed.
inRandomOrder() queries — caching is automatically disabled since results should differ each time.

📦 Installation

composer require genealabs/laravel-model-caching

✨ The service provider is auto-discovered. No additional setup is required.

🚀 Getting Started

Add the Cachable trait to your models. The recommended approach is a base model that all other models extend:

<?php

namespace App\Models;

use GeneaLabs\LaravelModelCaching\Traits\Cachable;
use Illuminate\Database\Eloquent\Model;

abstract class BaseModel extends Model
{
    use Cachable;
}

Alternatively, extend the included CachedModel directly:

<?php

namespace App\Models;

use GeneaLabs\LaravelModelCaching\CachedModel;

class Post extends CachedModel
{
    // ...
}

🎉 That's it — all Eloquent queries and eager-loaded relationships on these models are now cached and automatically invalidated.

⚠️ Note: You can cache the User model — the Cachable trait does not conflict with Laravel's authentication. Just avoid using cache cool-down periods on it, and ensure user updates always go through Eloquent (not raw DB::table() queries) so cache invalidation fires correctly.

🌍 Real-World Example

Consider a blog with posts, comments, and tags:

class Post extends BaseModel
{
    public function comments()
    {
        return $this->hasMany(Comment::class);
    }

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

// All cached automatically — the query, the eager loads, everything. 🪄
$posts = Post::with('comments', 'tags')
    ->where('published', true)
    ->latest()
    ->paginate(15);

When a new comment is created, the cache for Post and Comment queries is automatically invalidated — no manual Cache::forget() calls needed. 🧹

⚙️ Configuration

Publish the config file:

php artisan modelCache:publish --config

This creates config/laravel-model-caching.php:

return [
    'cache-prefix'         => '',
    'enabled'              => env('MODEL_CACHE_ENABLED', true),
    'use-database-keying'  => env('MODEL_CACHE_USE_DATABASE_KEYING', true),
    'store'                => env('MODEL_CACHE_STORE'),
    'fallback-to-database' => env('MODEL_CACHE_FALLBACK_TO_DB', false),
];

🔧 Environment Variables

Variable	Default	Description
`MODEL_CACHE_ENABLED`	`true`	✅ Enable or disable caching globally.
`MODEL_CACHE_STORE`	`null`	💾 Cache store name from `config/cache.php`. Uses the default store when not set.
`MODEL_CACHE_USE_DATABASE_KEYING`	`true`	🔑 Include database connection and name in cache keys. Important for multi-tenant or multi-database apps.
`MODEL_CACHE_FALLBACK_TO_DB`	`false`	🛡️ When `true`, falls back to direct database queries if the cache backend is unavailable (e.g. Redis is down) instead of throwing an exception.

📝 Note: The cache-prefix option is set directly in the config file (not via an environment variable). For dynamic prefixes (e.g. multi-tenant), use the per-model $cachePrefix property shown below.

💾 Custom Cache Store

To use a dedicated cache store for model caching, define one in config/cache.php and reference it:

MODEL_CACHE_STORE=model-cache

🏷️ Cache Key Prefix

For multi-tenant applications you can isolate cache entries per tenant. Set the prefix globally in config:

'cache-prefix' => 'tenant-123',

Or per-model via a property:

<?php

namespace App\Models;

use GeneaLabs\LaravelModelCaching\Traits\Cachable;
use Illuminate\Database\Eloquent\Model;

class Post extends Model
{
    use Cachable;

    protected $cachePrefix = 'tenant-123';
}

🔌 Multiple Database Connections

When use-database-keying is enabled (the default), cache keys automatically include the database connection and name. This keeps cache entries separate across connections without any extra configuration.

🚫 Disabling Cache

There are three ways to bypass caching:

1. Per-query (only affects this query chain, not subsequent queries):

$results = MyModel::disableCache()->where('active', true)->get();

2. Globally via environment:

MODEL_CACHE_ENABLED=false

3. For a block of code:

$result = app('model-cache')->runDisabled(function () {
    return MyModel::get();
});

// or via the Facade
use GeneaLabs\LaravelModelCaching\Facades\ModelCache;

ModelCache::runDisabled(function () {
    return MyModel::get();
});

💡 Tip: Use option 1 in seeders to avoid pulling stale cached data during reseeds.

❄️ Cache Cool-Down Period

In high-traffic scenarios (e.g. frequent comment submissions) you may want to prevent every write from immediately flushing the cache. Cool-down requires two steps:

Declare the default duration on the model (this alone does nothing — it just sets the value):

<?php

namespace App\Models;

use GeneaLabs\LaravelModelCaching\Traits\Cachable;
use Illuminate\Database\Eloquent\Model;

class Comment extends Model
{
    use Cachable;

    protected $cacheCooldownSeconds = 300; // 5 minutes ⏱️
}

Activate the cool-down by calling withCacheCooldownSeconds() in your query. This writes the cool-down window into the cache store:

// Activate using the model's default (300 seconds)
Comment::withCacheCooldownSeconds()->get();

// Or override with a specific duration
Comment::withCacheCooldownSeconds(30)->get();

Once activated, writes during the cool-down window will not flush the cache. After the window expires, the next write triggers a flush and re-warms the cache. 🔄

🛡️ Graceful Fallback

When enabled, if the cache backend (e.g. Redis) is unavailable the package logs a warning and falls back to querying the database directly — your application continues to function without caching rather than throwing an exception.

MODEL_CACHE_FALLBACK_TO_DB=true

🧹 Cache Invalidation

Cache is automatically flushed when:

Trigger	Behavior
Model created	Flush model cache
Model updated/saved	Flush model cache
Model deleted	Flush only if rows were actually deleted
Model force-deleted	Flush only if rows were actually deleted
Pivot `attach` / `detach` / `sync` / `updateExistingPivot`	Flush relationship cache
`increment` / `decrement`	Flush model cache
`insert` / `update` (builder)	Flush model cache
`truncate`	Flush model cache

Cache tags are generated for the primary model, each eager-loaded relationship, joined tables, and morph-to target types, so only the relevant entries are invalidated. 🎯

🔗 BelongsToMany with Custom Pivot Models

Cache invalidation works for BelongsToMany relationships using custom pivot models (->using(CustomPivot::class)) as long as either the parent or the related model uses the Cachable trait.

🧹 Manual Cache Flushing

Artisan command — single model:

php artisan modelCache:clear --model='App\Models\Post'

Artisan command — all models:

php artisan modelCache:clear

🔧 Programmatic via Facade:

use GeneaLabs\LaravelModelCaching\Facades\ModelCache;

// Single model
ModelCache::invalidate(App\Models\Post::class);

// Multiple models
ModelCache::invalidate([
    App\Models\Post::class,
    App\Models\Comment::class,
]);

⏰ Cache Expiration (TTL)

Cached queries are stored indefinitely (rememberForever) and rely on automatic invalidation (see above) to stay fresh. There is no per-query TTL option. If you need time-based expiry, use the cool-down period feature or flush the cache on a schedule via the Artisan command.

🧪 Testing

In your test suite you can either disable model caching entirely or use the array cache driver:

🚫 Disable caching in tests:

// In your TestCase setUp() or phpunit.xml
config(['laravel-model-caching.enabled' => false]);

✅ Use the array driver (useful for testing cache behavior itself):

config(['cache.stores.model-test' => ['driver' => 'array']]);
config(['laravel-model-caching.store' => 'model-test']);

👷 Queue Workers

The package has no special queue or Horizon integration. Cached queries inside queued jobs work the same as in HTTP requests. Cache invalidation triggered in a web request is immediately visible to queue workers (assuming a shared cache store like Redis). No additional configuration is needed.
