Question

我尝试在 edit.blade.php 中进行模型绑定，但是，数据库host_firstname中的字段名与表单host-firstname的字段名不同因此，当我们运行时，数据库中的数据不会显示在字段中。（我也不想在我的视图中更改数据字段名称）

我对Laravel很新，我不确定如何在模型中设置默认键名以使其正常工作。有没有人对此有任何解决方案？

数据库架构

  family_general_id int(10) unsigned NOT NULL AUTO_INCREMENT,

  host_firstname varchar(255) COLLATE utf8_unicode_ci NOT NULL,

  host_lastname varchar(255) COLLATE utf8_unicode_ci NOT NULL,

edit.blade.php

 {!! Form::model($survey, ['method' => 'PATCH', 'url' => 'surveys/' . $survey->family_general_id]) !!}
    <!-- Host-firstname Form Input-->
    <div class="form-group">
        {!! Form::label('host-firstname', 'Firstname:') !!}
        {!! Form::text('host-firstname', null, ['class' => 'form-control']) !!}
    </div>

    <!-- Host-lastname Form Input-->
    <div class="form-group">
        {!! Form::label('host-lastname', 'Lastname:') !!}
        {!! Form::text('host-lastname', null, ['class' => 'form-control']) !!}
    </div>
    {!! Form::close() !!}

我不确定此刻是否可行。我看了一下Illuminate / Html / FormBuilder，你可以看到transformKey()仅适用于under_scores

/**
 * Get the model value that should be assigned to the field.
 *
 * @param  string  $name
 * @return string
 */
protected function getModelValueAttribute($name)
{
    if (is_object($this->model))
    {
        return object_get($this->model, $this->transformKey($name));
    }
    elseif (is_array($this->model))
    {
        return array_get($this->model, $this->transformKey($name));
    }
}

    protected function transformKey($key)
        {
            return str_replace(array('.', '[]', '[', ']'), array('_', '', '.', ''), $key);
        }

我可以建议使用基本laravel表单构建器的解决方案，因为这是一个特例：

{!! Form::open(['method' => 'PATCH', 'url' => 'surveys/' . $survey->family_general_id]) !!}
    <!-- Host-firstname Form Input-->
    <div class="form-group">
        {!! Form::label('host-firstname', 'Firstname:') !!}
        {!! Form::text('host-firstname', null, ['class' => 'form-control']) !!}
    </div>

    <!-- Host-lastname Form Input-->
    <div class="form-group">
        {!! Form::label('host-lastname', 'Lastname:') !!}
        {!! Form::text('host-lastname', null, ['class' => 'form-control']) !!}
    </div>
    {!! Form::close() !!}

然后执行以下操作：

class SurveyController extends Controller
{
  //after validation
  $host_firstname = Input::get('host-firstname');

  //send this to your database $host_firstname
  $survey = new Survey;

  $survey->host_firstname = $host_firstname;

  $survey->save(); 
}
