没有模型的查询结果

Question

web.php

D/LogDebug: [P, o, k, é, m, o, n,  , S, h, o, p]
D/LogDebug: getUTF8Length() = 12

（型号） 的 Chapter.php

Route::get('/books/{book}/chapter/{chapter}', [
            'uses' =>'PostController@index'])->where(['book'=>'[-a-z0-9]+','chapter'=>'[0-9]+']);

我收到如下错误

章节模型如下所示。

Chapter.php

<?php

namespace App\Model;

use Illuminate\Database\Eloquent\Model;

class Chapter extends Model
{

}

Answer 1

您需要在模型中插入您的字段：

<?php

namespace App\Model;

use Illuminate\Database\Eloquent\Model;

class Chapter extends Model
{
    protected $table = 'chapter';
    protected $fillable = ['id','book_id','title','preface','number','createdAt','updatedAt','createdBy','updatedBy','deletedBy']; 
}

在模型中插入章节模型的所有字段。再试一次

Answer 2

您使用错误的语法在$table属性中定义字段。 $table应该具有数据库表的名称！ 此外，您可以设置质量分配可填写字段。

class Chapter extends Model
{
    protected $table = 'chapter'; // database table name
    protected $fillable = ['id','book_id','title','preface','number','createdAt','updatedAt','createdBy','updatedBy','deletedBy']; // 
}

如果您想在模型中定义字段，可以使用$fields（来自https://laracasts.com/discuss/channels/eloquent/model-definition的示例）：

$fields = [
    'firstName' => [
        'cast' => 'string',  // default, can be omitted
        'maxlength' => 100, 
        'column' => 'first_name', 
    ],
    'lastName' => [
        'cast' => 'string',  // default, can be omitted
        'maxlength' => 100, 
        'column' => 'last_name', 
    ],
    'isAdmin' => [
        'cast' => 'boolean',
        'column' => 'is_admin', 
    ],
]
