Unable to Import Featured Images During theme:seed (Importer Rejects featured_image_urls)

[SamBrishes]

I’m trying to seed RainLab.Blog posts using php artisan theme:seed command, and I’d like to include demo images as well.

Thus, in my data.yaml, I first import the media files, then the RainLab.Blog posts:

-
    name: Demo Media Files
    class: Media\Models\MediaLibraryItemImport
    file: seeds/data/media-files.json
    attributes:
        file_format: json
-
    name: Demo RainLab.Blog Posts
    class: RainLab\Blog\Models\PostImport
    file: seeds/data/rainlab-blog.json
    attributes:
        file_format: json
        auto_create_categories: true

My media-files.json is as simple as

[
    {
        "type": "folder",
        "path": "newshub/demo",
        "source": "seeds/media"
    }
]

The problem is that the images cannot be imported. The exported Blog Posts contain a featured_image_urls attribute (which is empty, though), but the importer rejects it because this attribute does not exist on the Post model.

Error: SQLSTATE[HY000]: General error: 1 table rainlab_blog_posts has no column named featured_image_urls

My intended approach was to stay using the featured_image_urls, but - at least for the seeder - with internal storage paths that already exist from the media importer. Example Post:

[

    {
        "title": "Title",
        "categories": ["Articles", "Featured"],
        "created_at": "2022-08-13T14:53:24.000000Z",
        "updated_at": "2022-08-13T14:53:24.000000Z",
        "published_at": "2022-08-13 14:53:14",
        "content": "Post Content.",
        "content_html": "<p>Post HTML Content</p>",
        "excerpt": "",
        "slug": "title",
        "author_email": "sam@rat.md",
        "featured_image_urls": [
            "newshub/demo/hero-image-01.jpg"
        ],
        "published": 1
    },
]

Then in your PostImport.php on line 67, create File objects like this:

foreach (array_except($data, $except) as $attribute => $value) {
    if (in_array($attribute, $post->getDates()) && empty($value)) {
        continue;
    }
    if ($attribute == 'featured_image_urls') {
        $value = is_array($value) ? $value : [$value];
        $files = [];
        foreach ($value AS $image) {
            $filePath = storage_path('app/media/' . $image);
            if (empty($image) || !file_exists($filePath) || !is_file($filePath)) {
                continue;
            }

            $files[] = (new \System\Models\File)->fromFile(
                $filePath,
                basename($image)
            );
        }
        if (!empty($files)) {
            $post->featured_images = $files;
        }
    } else {
        $post->{$attribute} = isset($value) ? $value : null;
    }
}

Or is there a more native or recommended way to import images along with the Blog posts?

Thanks.
