Hi, I use Builder, I want to bring out thumbnail, which is loaded in another field. But I get the error:

Call to a member function getPath() on null

Model

public $attachOne = [
        'img' => 'System\Models\File'
    ];

Partial

<img src="<?php echo $model->img->getPath(); ?>" />

Are you sure there's actually an image attached to this model record?

Yes, File upload shows the name of the file, and the url is valid

It's hard to answer without more details... where does the $model variable comes from in the partial? Show more of your code.

<?php namespace gohhan\Portfolio\Models;

use Model;

/**
 * Model
 */
class Book extends Model
{
    use \October\Rain\Database\Traits\Validation;

    /*
     * Disable timestamps by default.
     * Remove this line if timestamps are defined in the database table.
     */
    public $timestamps = false;

    /**
     * @var string The database table used by the model.
     */
    public $table = 'vebprovajder_portfolio_kuhni';

    /**
     * @var array Validation rules
     */
    public $rules = [
    ];
    public $attachOne = [
        'img' => 'System\Models\File'
    ];
}

And your controller/partials?

Field Partial it displays thumbnail

<img src="<?php echo $model->img->getPath(); ?>" />

Controllers

<?php namespace gohhan\Portfolio\Controllers;

use Backend\Classes\Controller;
use BackendMenu;

class Book extends Controller
{
    public $implement = [        'Backend\Behaviors\ListController',        'Backend\Behaviors\FormController',        'Backend\Behaviors\ReorderController'    ];

    public $listConfig = 'config_list.yaml';
    public $formConfig = 'config_form.yaml';
    public $reorderConfig = 'config_reorder.yaml';

    public function __construct()
    {
        parent::__construct();
        BackendMenu::setContext('gohhan.Portfolio', 'portfolio', 'book');
    }
}

It doesn't show where the $model variable used in your partial is assigned...

I stupidly copied $model variable from the documentation :)

Then how can I create a variable for a downloaded file and use in Partial?

What does your Models/book/fields.yaml look like?

And where exactly do you want to show this thumbnail? In a backend form or on a front-end CMS page?

fields:
    title:
        label: Name
        span: left
        type: text
    img:
        label: 'Image'
        mode: file
        useCaption: true
        thumbOptions:
            mode: crop
            extension: auto
        span: right
        type: fileupload
    description:
        label: Description
        size: ''
        span: auto
        type: richeditor
    thumbnail:
        span: right
        readOnly: 1
        path: ~/plugins/gohhan/portfolio/models/img/thumbnail_field.htm
        type: partial

~You're right, $model should contains the model instance in your partial... ~

$model contains the FIELD instance for a field... $formModel contains the actual model used by the form.

Try using $formModel instead of $model...

Like this:

<img src="<?= $formModel->img->getPath() ?>" />

It seems you were right, img is empty?

Call to a member function getPath() on null

Are you trying to see the thumbnail BEFORE saving the model or after??

After.

I think I've set myself a bad task and I'm taking your time.

You're right, if I open the first time the record then I will have a bug that img empty. So you need to check img for an empty value.

In my cases it is easier in fields.yaml to change mode: file on mode: image

Then I'll see thumbnail. It's a pity that you couldn't learn how to display a uploaded image where you need to :)

I found a problem! Looked at the database, in the plugin table, the img column is empty. The image is uploaded but not recorded in the database. Why don't I know.
