When developing Laravel projects, you often encounter situations where you need to store some irregular or dynamic data in your model. The traditional Eloquent model requires strict schemas, which makes it difficult to store data flexibly. Recently, I encountered this problem while working on a project and after trying multiple methods, I finally solved this problem with the spatie/laravel-schemaless-attributes library.

Problem description

In my project, you need to store user's custom properties, which may include various types of data, such as strings, arrays, objects, etc. Using the traditional Eloquent model, each time you add a new property, you need to modify the database schema, which obviously does not meet the flexibility requirements.

Solution

The spatie/laravel-schemaless-attributes library provides a method to use schema-free attributes in the Eloquent model. It allows you to store arbitrary data in a JSON column, enabling NoSQL-like flexibility.

Install

Installing the library using Composer is very simple:

 <code class="bash">composer require spatie/laravel-schemaless-attributes</code>

Configuration

First, you need to add a JSON column to the model's table to store these schema-free properties:

 <code class="php">Schema::table('your_models', function (Blueprint $table) { $table->schemalessAttributes('extra_attributes'); });</code>

Then, add a custom cast and scope to the model:

 <code class="php">use Illuminate\Database\Eloquent\Model; use Illuminate\Database\Eloquent\Builder; use Spatie\SchemalessAttributes\Casts\SchemalessAttributes; class YourModel extends Model { public $casts = [ 'extra_attributes' => SchemalessAttributes::class, ]; public function scopeWithExtraAttributes(): Builder { return $this->extra_attributes->modelScope(); } }</code>

use

After using this library, you can easily add, get, and update schema-free properties:

 <code class="php">// 添加屬性$yourModel->extra_attributes->name = 'value'; // 獲取屬性$yourModel->extra_attributes->name; // 返回'value' // 使用數(shù)組方式$yourModel->extra_attributes['name'] = 'value'; $yourModel->extra_attributes['name']; // 返回'value' // 一次設(shè)置多個(gè)值$yourModel->extra_attributes = [ 'rey' => ['side' => 'light'], 'snoke' => ['side' => 'dark'] ]; // 使用set() 方法設(shè)置/更新多個(gè)值$yourModel->extra_attributes->set([ 'han' => ['side' => 'light'], 'snoke' => ['side' => 'dark'] ]); // 使用點(diǎn)符號獲取值$yourModel->extra_attributes->get('rey.side'); // 返回'light' // 獲取不存在的屬性時(shí)返回默認(rèn)值$yourModel->extra_attributes->get('non_existing', 'default'); // 返回'default' // 刪除鍵值對$yourModel->extra_attributes->forget('key');</code>

Advantages and effects

After using the spatie/laravel-schemaless-attributes library, my project achieves the following advantages:

• Flexibility : It is easy to add and modify properties without modifying the database schema.
• Efficiency : All data is stored in a JSON column, reducing the complexity of database operations.
• Convenient query : provides powerful query functions, which can be filtered based on schema-free attributes.

Through this library, I successfully solved the problem of flexibly storing data in the Laravel model, greatly improving the project development efficiency and data management flexibility. If you are dealing with similar issues, you might as well try this library.
