Php 我不知道'；“得不到”；添加按钮"；在双肩包Laravel上使用内嵌式创建

遵循本文件： 我尝试在发票（主要）和发票行（次要）之间创建链接。 这个链接看起来不错，但是我没有成功地使用第二个表单所需的“+添加”按钮。

我的密码

主类（invoiceCrudController）

我认为你的定义是错误的：

$this->crud->addFields([
/其他情况/
[
“名称”=>“发票行”，
'类型'=>'关系'，
“标记”=>“发票行”，
“ajax”=>正确，
[//以单数形式指定实体
'entity'=>'invoiceLine'，//单数形式的实体
]
],

由于该关系与许多（我猜）有关，因此该文件应为：

[
    'type' => "relationship",
    'name' => 'invoiceLines', 
    'ajax' => true,
    'inline_create' => true, 
]
