Migrations and migration api came as surprise to me, really powerful stuff. It can be used as a tool for one of import of whatever content you might have or for continuous import of some data from any endpoint. With core import module, for proper framework I would suggest adding migrate tools and migrate plus modules.
First get current language
$language = \Drupal::languageManager()->getCurrentLanguage(\Drupal\Core\Language\LanguageInterface::TYPE_CONTENT)->getId();then load term with providing term id
If you created some migration config and then you renamed it later, there is a good chance it is still present in config and it can also break your migration UI for that migration group. To clear that out, check your config with drush cedit find id of config and run this in devel/php or drush php
Whole migration mapping is done in yaml files. So there are few things you need to know when doing custom migration configs.
You want to check some environment variables values for your current setup. Log into mysql and type something like
To force users or administrators to have predefined list of what to put into some field you will need to use one of this 2 solutions, text list or taxonomy term reference field.
Maybe you came to that annoying message when you want to save something in PHP Storm but it refuses to and gives you options "cancel" or "revert changes", usually happens around some config files, like settings.php. Why is this so? Probably because you didn't put write permissions to folder where phpstorm is trying to write its temp files.
When you set or override some variables in settings.php with $settings var and want to get it in your code, call it like this.
use Drupal\Core\Site\Settings;
$mySetting = Settings::get('some_setting', NULL);
I see many people use https://www.drupal.org/project/eck module when they want to create new entites in drupal 8. But there is a problem with that. By default ECK module in UI doesn't create base fields, you can create bundles and then add fields to them.
