表单更新数据库模型记录的关系

Question

我想知道如何使用前端表单更新模型的关系。我查看了文档，发现：

Alternatively you may set the relationship using the primary key, this is useful when working with HTML forms.

// Assign to author with ID of 3
$post->author = 3;

// Assign comments with IDs of 1, 2 and 3
$post->comments = [1, 2, 3];

$post->save();

更新关系的后端表单工作正常。这是我的代码，我在其中获取 ID 作为值，但它似乎并不影响关系字段。非常感谢帮助！

    $project = new Projects(); 
    $project->name = Input::get('name');
    $project->price = Input::get('price');
    $project->work = Input::get('work');
    $project->client = Input::get('client');
    $project->slug = $slug;
    $project->save();
    Flash::success('Estimate Added!');
    return Redirect::refresh();

这是枢轴 Table:

public function up()
    {
        Schema::create('brandon_invoice_ip', function($table)
        {
            $table->engine = 'InnoDB';
            $table->integer('invoices_id');
            $table->integer('projects_id');
            $table->primary(['invoices_id','projects_id']);
        });
    }

    public function down()
    {
        Schema::dropIfExists('brandon_invoice_ip');
    }
}

模型关系如下：

public $hasOne = [
        'client' => 'Brandon\Invoice\Models\Clients'
    ];

这是前端表单：值根据其 ID 是正确的。

<div class="uk-margin uk-first-column">
    <label class="uk-form-label" for="client">Client</label>
    <div class="uk-form-controls">
        <select class="uk-select" name="client">
          <option value="1">Brandon</option>
          <option value="2">Sanitary Ostomy System</option>
        </select>
    </div>
</div>

Answer 1

使用以下方式设置客户端后：

$project->client = Input::get('client');

您需要使用以下方式保存更改：

$project->save();

假设您的表格和模型已正确设置，以上应该有效。如果没有，您需要 post 表的结构和其余代码。

Answer 2

我认为你需要添加 belongsTo 关系而不是 hasOne

public $belongsTo = [
    'client' => 'Brandon\Invoice\Models\Clients'
];
