【问题描述】:
我将 Bllim/Datatables 包用于我的 Web 应用程序中的数据表;但我无法检索所有相关行。
我使用下面的代码:
$books= $client->books()->where('books.type', 0);
然后我将它发送到 Datatables::of 方法如下:
return Datatables::of($books)
->edit_column('type', '{{$type}}')
->edit_column('created_at', function($obj) {
return $obj->created_at->format('d/m/Y (h:i)');
})
->set_index_column('id')
->make();
但所有这些都返回内部服务器错误 (500) 并带有以下消息:
{"error":
{
"type":"ErrorException",
"message":"Undefined property: Illuminate\\Database\\Eloquent\\Builder::$columns",
"file":"\/var\/www\/clients\/myapp\/vendor\/bllim\/datatables\/src\/Bllim\/Datatables\/Datatables.php",
"line":256
}
}
我的数据库结构:
create table clients(
id int not null auto_increment,
name varchar(10) not null,
password varchar(60) not null,
unique(name),
primary key(id),
created_at timestamp NOT NULL DEFAULT '0000-00-00 00:00:00',
updated_at timestamp NOT NULL DEFAULT now() ON UPDATE now()
)CHARSET utf8 COLLATE utf8_spanish_ci;
/* PIVOT TABLE */
create table book_client(
id int not null auto_increment,
book_id int,
client_id int,
primary key(id),
FOREIGN KEY (book_id ) REFERENCES books(id) ON DELETE CASCADE,
FOREIGN KEY (client_id ) REFERENCES clients(id) ON DELETE CASCADE
)CHARSET utf8 COLLATE utf8_spanish_ci;
create table books(
id int not null auto_increment,
name varchar(50) not null,
description varchar(500),
type varchar(10) not null,
primary key(id),
created_at timestamp NOT NULL DEFAULT '0000-00-00 00:00:00',
updated_at timestamp NOT NULL DEFAULT now() ON UPDATE now()
)CHARSET utf8 COLLATE utf8_spanish_ci;
在 views 我有下一个:
/*In the view of clients*/
public function books(){
return $this->belongsToMany("Book");
}
/*In the view of books: (yes, in my case, a book could belong to multiple clients*/
public function clients(){
return $this->belongsToMany("Client");
}
有人知道我需要的制作方法吗?

如果我的问题是混淆...我可以重写它。
