function commerce_price_form_views_ui_config_item_form_alter in Commerce Core 8.2

Implements hook_form_FORM_ID_alter().

Removes the "Calculated price" formatter from views field options, if it is not applicable. Since the formatter is product variation specific, this prevents it from accidentally being used on other entity types.

@todo Remove when https://www.drupal.org/node/2991660 gets fixed.

File

modules/price/commerce_price.module, line 55

Defines the Currency entity and the Price field.
