+title: One Of Many Example
+weight: 8
+---
+
+When trying to retrieve "OneOfMany", you may experience duplicate records.
+
+Core functionality for this will be added in due course, this is simply a work-around.
+
+In the meantime, to avoid this, you can use the following approach.
+
+This example assumes two Models:
+User -> HasMany -> Things
+
+### Models
+#### User
+id
+name
+created_at
+updated_at
+etc
+
+```php
+    public function things(): \Illuminate\Database\Eloquent\Relations\HasMany
+    {
+        return $this->hasMany(Things::class);
+    }
+```
+
+#### Things
+id
+name
+user_id
+created_at
+updated_at
+
+### Table
+The following is the table code for this example, and retrieves the most recently created "Thing"
+
+#### Column
+```php
+    Column::make('Latest Thing')
+    ->label(
+        fn ($row, Column $column) => $row->things->first()->name
+    ),
+```
+
+#### Builder
+```php
+    public function builder(): Builder {
+
+        return User::query()->with(['things' => function ($query) {
+                $query->select(['id','user_id','name'])->orderBy('created_at', 'desc')->limit(1);
+        }]);
+
+    }
+```
+
+Core functionality for this will be added in due course, this is simply a work-around.
