Customizing Thumbnails Issue

[tschmidiger]

When trying to customize the thumbnail URL generation method, $this->value is empty because $this refers to the current resource model and not the field class.

Image::make('Profile Photo')
    ->disk('public')
    ->thumbnail(function () {
        return $this->value
                    ? Storage::disk($this->disk)->url($this->value)
                    : null;
})

As a work-around I just replaced $this->value with $this->image which refers directly to the column name of the resource model.

That's right, the docs need to be updated.

You can access the value using $this->value only within the preview override function within the Field classes, but if you override it in the Resource this will not work and you must use the column name as you do.

In next release the value and disk properties will be pass to callback.

->thumbnail(function ($value, $disk) {
    return Storage::disk(value)->url($disk);
})

@davidhemphill The docs need updating. I also had to check the issues to get past this.

@jboka maybe open a issue on https://github.com/laravel/nova-docs/issues detailing what needs to be updated in the docs / your workaround
