关于条件搜索 + 多选 + 多对多的写法 比如tags那种
filament
Select::make('tags')
// ->relationship('tags', 'name' )
//->options(Tags::all()->pluck('name', 'id'))
->relationship('tags', 'name', function (Builder $query) {
return $query->where('user_id', 1);
})
->preload()
->searchable()
->label('标签')
->required()
->multiple(),
tags方法
<?php
namespace App\Models;
use Illuminate\Database\Eloquent\Factories\HasFactory;
use Illuminate\Database\Eloquent\Model;
use Illuminate\Database\Eloquent\Relations\HasMany;
use App\Models\PromotionTask;
use App\Models\Tags;
use App\Models\User;
use Illuminate\Database\Eloquent\Relations\BelongsTo;
use Illuminate\Database\Eloquent\Relations\BelongsToMany;
class CopyWriting extends Model
{
/**
* The attributes that should be cast.
*
* @var array
*/
protected $casts = [
'tags' => 'array',
];
use HasFactory;
public function tags(): BelongsToMany
{
return $this->belongsToMany(Tags::class, 'copy_writing_tags', 'copy_writing_id', 'tags_id') ;
}
}
多对多那部分的方法
<?php
namespace App\Models;
use Illuminate\Database\Eloquent\Factories\HasFactory;
use Illuminate\Database\Eloquent\Model;
use Illuminate\Database\Eloquent\Relations\HasMany;
use Illuminate\Database\Eloquent\Relations\BelongsToMany;
use App\Models\CopyWriting;
class Tags extends Model
{
use HasFactory;
public function copywriting(): BelongsToMany
{
return $this->belongsToMany(CopyWriting::class, 'copy_writing_tags', 'copy_writing_id', 'tags_id');
}
}
