  6. 6. About Jay• Mediacurrent Web Developer• Developed Drupal sites since version 4.6• Why Features? o Started using features in early 2010 o Developed features extensively on a large OpenPublish- based multi-site installation, working with Phase2 o Now use features on every site big and small• OpenChurch distribution maintainer o Features used extensively
  7. 7. The Problem• Drupal has many items in the database o Views o CCK Content types o Imagecache o Context o Panels o Settings o Permissions• Moving these between environments is cumbersome• Backing these up is a pain• No version control• Developers can accidentally override each others work
  8. 8. The Solution - Features!• Features Benefits: o Work more in the „problem space‟ o Encapsulation - Yes! o Backup - Yes! o Version Control - Yes! o Easier deployment o Code reuse! o A place for your form_alters and nodeapi() hooks o Drush integration• And much, much more! o Replace (or supplement) install profiles!  Features break an install into components o Create a distribution with drush .make  (music site, newspaper site, govt, blog, etc)
  9. 9. How to Create a Feature• Install and Enable the Following: o Features o Strongarm (important)  Saves additional settings with your content types that would otherwise not get save o Context  Recommended over admin/build/block o Diff (recommended, only on non-production environments)  Can view differences in code
