Drupal - Features workflow issue with deleting a field
The correct way to remove Features-created content is via hook_update_N (which should be implemented in the file
The main idea with Features is to manage configuration with code. Using
hook_update_N is consistent with that, since the field deletion is in code (which can be managed with version control) — whereas the equivalent command
drush field-delete field is not being called from managed code; it's a separate command-line step you need to perform (and to remember to perform).
This is a double edged sword, it's like this to prevent data deletion which is always a good thing. There's nothing really to solve, this is expected behaviour.
It's the same workflow we use and have been doing for over a year and it works really well. I'd say it's correct but that's a very subjective answer.
Create a new file called "your_feature_name.install"
Inside the file declare hook_update_N, there you can use field_delete_field() and specify the name of field that you want to delete as parameter.
Run update.php and the fields will be deleted.
