If you use the Features module to manage your Drupal configuration, it can be time consuming to update features through the UI, especially if you are working on a remote server and need to keep downloading and uploading files.
If you re-create a feature through the UI, you’ll be prompted to download a new archive of the feature in its entirety onto your local computer. You could either commit this into a local repository and then pull it remotely, or use a tool such as SCP to upload the archive onto the server and commit it from there. You can simplify this process by using Drush.
To search for a component, use the
drush features-components command. This
will display a list of all components on the site. As we’re only interested in
components that haven’t been exported yet, add the
--not-exported option to
filter the results.
To filter further, you can also use the
grep command to filter the results.
drush features-components --not-exported field_base | grep foo,
would only return non-exported field bases containing the word “foo”.
The result is a source and a component, separated by a colon. For example,
Exporting the Feature
Once you have a list of the components that you need to add, you can export the
feature. This is done using the
drush features-export command, along with the
feature name and the component names.
$ drush features-export -y myfeature field_base:field_foo field_instance:user-field_foo
In this example, the base for field_boo and it’s instance on the user object is being added to the “myfeature” feature.
If you are updating an existing feature, you’ll get a message informing you that
the module already exists and asking if you want to continue. This is fine, and
is automatically accepted by including
-y within the command. If a feature
with the specified name doesn’t exist, it will be created.
If you’re creating a new feature, you can define where the feature will be
created using the
Once complete, you will see a confirmation message.
Created module: my feature in sites/default/modules/custom/features/myfeature
Once finished, the feature is updated in it’s original location, so there’s no download of the feature and then needing to re-upload it. You can add and commit your changes into Git or continue with your standard workflow straight away.
