+## 模型的作用域
+
+- 本地作用域
+- 全局作用域
+
+1、本地作用域
+
+```php
+class User extends Model
+{
+    // 本地作用域 查询条件：成年人
+    public function scopeAdult($query)
+    {
+        return $query->where('age', '>', 18);
+    }
+}
+```
+
+```php
+User::adult()->get();
+// select * from `user` where `age` > ?
+```
+
+支持传递参数
+
+```php
+class User extends Model
+{
+    // 本地作用域 支持传递参数
+    public function scopeQueryWhere($query, $where)
+    {
+        return $query->where($where);
+    }
+}
+```
+
+```php
+User::queryWhere([
+            ['age', '>', 10]
+    ])->get();
+// select * from `user` where (`age` > ?)
+```
+
+2、全局作用域
+
+定义全局作用域
+
+```php
+<?php
+
+namespace App\Scopes;
+
+use Illuminate\Database\Eloquent\Builder;
+use Illuminate\Database\Eloquent\Model;
+use Illuminate\Database\Eloquent\Scope;
+
+class StatusScope implements Scope
+{
+    public function apply(Builder $builder, Model $model)
+    {
+        return $builder->where('status', 1);
+    }
+}
+```
+
+```php
+class User extends Model
+{
+    // 启用全局作用域
+    protected static function booted() {
+        parent::booted();
+        
+        // 全局公共模块
+        static::addGlobalScope(new StatusScope());
+
+        // 或者 只是针对某个模块
+        static::addGlobalScope('status', function (Builder $builder) {
+            return $builder->where('status', 1);
+        });
+    }
+}
+```
+
+使用
+
+```php
+User::queryWhere([
+        ['age', '>', 10]
+    ])->get();
+// select * from `user` where (`age` > 10) and `status` = 1
+```
+
+取消全局条件
+
+```php
+// 取消全局类的条件
+User::withoutGlobalScope(StatusScope::class)->get();
+// select * from `user`
+
+// 取消名称为 status 的全局
+User::withoutGlobalScope('status')->get();
+// select * from `user`
+```
