SOLVED, both methods below work perfectly fine, it was just a typo.
I need to programmatically update a field's config in hook_update. I need to do this on multiple projects, so I can't use the normal way with field UI and config sync. I've found documentation how to update the field storage and DB schema (1, 2), but no documentation how to update a field config only, so I assumed I can go along with common ConfigFactory.
/**
* Add my new paragraph to the list of allowed bundles in the host field config
*/
function MYMODULE_update_9001(&$sandbox) {
$config = \Drupal::configFactory()->getEditable('field.field.node.BUNDLE.FIELD_NAME');
$existingAllowedParagraphs = $config->get('settings.handler_settings.target_bundles');
if (!in_array('NEW_PARAGRAPH_BUNDLE', $existingAllowedParagraphs )) {
$dependencies = $config->get('dependencies.config');
$dependencies[] = 'paragraphs.paragraphs_type.NEW_PARAGRAPH_BUNDLE';
$config->set('dependencies.config', $dependencies);
$config->set('settings.handler_settings.target_bundles.NEW_PARAGRAPH_BUNDLE', 'NEW_PARAGRAPH_BUNDLE');
$config->set('settings.handler_settings.target_bundles_drag_drop.NEW_PARAGRAPH_BUNDLE', ['enabled' => true, 'weight' => 1234]);
$config->save(TRUE);
}
}
This worked only in active config (drush cex creates the expected, updated and correct YAML config), but weirdly not anywhere else. E.g. in Field UI or in the node edit form, everything works like the old, pre-hook config, it does not use the active config. I've tried doing multiple config imports and cache clears, but the field is not using the values from the ConfigFactory. I'm absolutely sure that my new config is correct and active, but somehow the field is now out of sync with its own config.
Update: I've also tried an alternative approach using FieldConfig, but the problem is exaclty the same: Proper active config, but no effect in field UI or node edit form.
/**
* Add tour to allowed slides in DGM TV
*/
function wt_dgm_update_9011(&$sandbox) {
/** @var $config Drupal\field\FieldConfigInterface */
$config = Drupal\field\Entity\FieldConfig::loadByName('node', 'dgmtv', 'field_slides');
$handlerSettings = $config->getSetting('handler_settings');
$allowedParagraphs = $handlerSettings['target_bundles'];
if (!in_array('dgmtour', $allowedParagraphs)) {
$dependencies = $config->get('dependencies');
$dependencies['config'][] = 'paragraphs.paragraphs_type.dgmtour';
$config->set('dependencies', $dependencies);
$handlerSettings['target_bundles']['dgmtour'] = 'dgmtour';
$handlerSettings['target_bundles_drag_drop']['dgmtour'] = ['enabled' => true, 'weight' => 1234];
$settings = $config->get('settings');
$settings['handler_settings'] = $handlerSettings;
$config->set('settings', $settings);
$config->save();
}
}
What else do I need to do so that the field uses the new config?
