Using Custom Class Model Files in a Child Theme

This theme is quite different from other themes I’ve used in regard to its template system. In addition, I am using the Modern model and much of the documentation on your website seems to apply to the Classic model.

I used the czr_post_list_loop_item_template filter (from loop.php) to change the post lists item template for a custom post type (online_exhibit). I called my custom template online_exhibit_list.php and based it on post_list_plain.php. However, my custom template did not render the same style-wise as the original and I realized it was because post_list_plain.php has a corresponding class model file (class-model-post_list_plain.php) while my new template does not.

So I made my own class model file (class-model-online_exhibit_list.php) by copying class-model-post_list_plain.php and renaming its class. I placed this in the proper location within my child theme directory and that allowed my new custom template to render properly style-wise.

However, I am wondering if this is a proper way to go about doing this. With other themes, I would likely just make a file called archive-online_exhibit.php based on the theme’s archive.php file. But this theme works differently and I’m trying to stay with the same structure and use the filters provided for my customization.
