Laravel Voyager overwrite BREAD controller
提问by Pedro
I've started to use Voyager and I've problems with a controller.
我已经开始使用 Voyager，但我在使用控制器时遇到了问题。
I've create a new table in database called Progress, voyager by default create a BREAD form to browse read delete and add items .
我在数据库中创建了一个名为 Progress 的新表，默认情况下 voyager 创建一个 BREAD 表单来浏览读取删除和添加项目。
I like to put a default value into a field when the user go to add a new item. The default value that I like to put is authentication user_id
我喜欢在用户添加新项目时将默认值放入字段中。我喜欢放置的默认值是 authentication user_id
How can I do that?
我怎样才能做到这一点？
Thanks.
谢谢。

You can do that completely outside of Voyager.
您可以完全在 Voyager 之外执行此操作。
First exclude the authentication_user_idfrom the Add form (in Voyager's database interface). If the field doesn't take a null value you can set some temporary default, or modify your migrations - whichever is most convenient.
首先authentication_user_id从添加表单（在 Voyager 的数据库界面中）中排除。如果该字段不采用空值，您可以设置一些临时默认值，或修改您的迁移 - 以最方便的方式为准。
Next create a model observerand then utilise the created()function. For example:
接下来创建一个模型观察者，然后利用该created()功能。例如：
<?php
namespace App\Observers;
use App\Models\Project;
class ProgressObserver
{
/**
* Listen to the Progress created event.
*
* @param Progress $progress
* @return void
*/
public function created(Progress $progress)
{
$progress->authentication_user_id = WHATEVER_YOU_DO_HERE;
$progress->save();
}
}

You can do that by creating a model for your bread, as shown in image
您可以通过为面包创建模型来做到这一点，如图所示
after you have done creating a model for your bread you can create a function named save
为面包创建模型后，您可以创建一个名为的函数 save
<?php
namespace App\Models;
use Illuminate\Database\Eloquent\Model;
use TCG\Voyager\Traits\Translatable;
use Illuminate\Support\Facades\DB;
use Carbon\Carbon;
use Auth;
class MyViewModel extends Model
{
//
protected $table = "my_view";
public function save(array $options = [])
{
$this->user_id = \Auth::user()->id;
parent::save();
}
}
now whenever you save any record in administration of voyager, you will see current login user id is getting saved in your database table.
现在，每当您在 voyager 管理中保存任何记录时，您都会看到当前登录用户 ID 被保存在您的数据库表中。

I think you can create a migration to write a default value for that field
我认为您可以创建迁移来为该字段写入默认值

You have to add following code into the modal like this,
您必须像这样将以下代码添加到模态中，
//assign created_by loggedin user
public function __construct(array $attributes = [])
{
$this->creating([$this, 'onCreating']);
parent::__construct($attributes);
}
public function onCreating($row)
{
// Placeholder for catching any exceptions
if (!\Auth::user()->id) {
return false;
}
$row->setAttribute('created_by', \Auth::user()->id);
$row->setAttribute('assign_to', \Auth::user()->id);
}
i have adding this because of my project need this. you can also add your field in onCreating() function.
我添加了这个是因为我的项目需要这个。您还可以在 onCreating() 函数中添加您的字段。
