Field Prefix

Customize the field prefix or remove the default prefix field_

Install this module and visit admin/config/field_prefix/setting

This module provides a setting form to edit the value of the field_prefix key in field_ui.settings.yml provided by the field_ui module, that's all.

So it's NOT RECOMMENDED to have this module installed -- who wants to have one more module installed if it's uninstallable.

You can use Drush or Drupal Console to do the same or uninstall this module after setting your desired field prefix. For example:

# Use Drupal Console
$ drupal config:override field_ui.settings --key='field_prefix' --value='YOUR_FIELD_PREFIX_OR_AN_EMPTY_STRING_TO_REMOVE_THE_DEFAELT_FIELD_PREFIX'
