I've tried everything I've found to modify a views_view_field, starting with the official docs. I've also tried multiple ways and parameters for the hooks HOOK_theme (with and without the parameters 'path', 'base hook') and HOOK_theme_registry_alter, but I'm still unable to make the twig in my module to override the original.
To make things simpler, I'm testing without any custom theme, without any folders under /templates, and the view I'm trying to modify is linked inside the admin pages. The twig suggestions clarify that the twig being displayed is the "stable" theme one.
The template in the theme takes precedence over the template in your module, so you will need to implement HOOK_theme_registry_alter to force Drupal to get the template from your module's folder.
/**
* Implements hook_theme_registry_alter().
*/
function mymodule_theme_registry_alter(&$theme_registry) {
// Replace the path to the registered template so that Drupal looks for
// it in your module's templates folder.
$theme_registry['views_view_field']['path'] = drupal_get_path('module', 'mymodule') . '/templates';
}
Make sure you clear your cache to force the theme registry to be updated.
