  10. What is the features module?

  11. What can you use features for? • Within your site (GUI) • Leveraging drush (command line)

  12. What are features’ limitations? • Imperfect exports • No site variables without third-party modules • No theme, block support • No control logic • If you can't do it in the GUI... "40+296 Hello?", CC BY 2.0 by Bark @ flickr

  13. Custom modules for granular control With hook_install(), you can programmatically… • Create users, roles, permissions • Create and hide blocks • Create content (nodes) • Import content types / CCK • Create vocabularies and terms (fields) • Set site variables (drushvget) • Import views

  14. Custom module “gotchas” • Custom modules used like this need a user associateddrush-u 1 -y en custom_module • Clear all caches after installing your custom moduledrushcc all • Changes and updates need to go in hook_update_N within your module

  15. Deployment strategies • Store everything in a versioning system • Always backup both your scripts and database first! • Tiered development strategy • Unique database credentials for each tier • When in doubt, rebuild on devfirst • Instead of repeating steps, do it in code • Document the process

  16. How can I do this? • Get drush • Get drush_make • Define your needs. • Build and document your module toolbox • Start small, then scale up
