Is there a way to use upload multiple for a 1-n relationship? Please help me

[tatvn]

Hi, i want to upload multiple file for a 1-n relationship.
In Article Model

public function filePath()
    {
        return $this->hasMany(ArticleFile::class, 'article_id');
    }

In ArticleFile Model

public function setFilePathAttribute($value)
    {
        $attribute_name = 'file_path';
        $disk = 'upload';
        $destination_path = '/storage/app/uploads/articles/' . Carbon::now()->format('Ym');
        $this->uploadMultipleFilesToDisk($value, $attribute_name, $disk, $destination_path);
    }

In ArticleController

CRUD::addField([
            'name' => 'file_path',
            'type'  => 'upload_multiple',
            'label' => '本文ファイル',
            'disk' => 'upload',
            'upload' => true,
])

Hey @tatvn

You can't use the upload_multiple field for a 1-n relationship. It stores the values as a JSON array in the database column.

If the relationship is important:

You can use https://backpackforlaravel.com/docs/6.x/crud-uploaders#uploaders-for-spatie-medialibrary

👆This associates all sorts of files with Eloquent models

OR

You can use relationship subfields(title, upload), try these steps and let me know if they help!

• Field setup: https://backpackforlaravel.com/docs/6.x/crud-fields#relationship-pro
• Save additional data to the pivot table: https://backpackforlaravel.com/docs/6.x/crud-fields#save-additional-data-to-pivot-table
• Handling uploads in relationship fields: https://backpackforlaravel.com/docs/6.x/crud-uploaders#handling-uploads-in-relationship-fields

OR

You can create a custom field using existing upload_multiple. You have to modify it & create your saving logic:
php artisan backpack:field new_field_name --from= upload_multiple

OR

Create a few accessor & mutator combos which turn JSON and save the values to a related table.
