4 0. The Prblem First slutin: dump the database t a text file and apply versin cntrl t it. Issues: Cnfiguratin and cntent are mixed: Cnfiguratin: CCK, Views, Blcks... Cntent: ndes If we deply t prductin, we get the new Views / Blcks, but we verwrite the cntent. Drupal versin cntrl and deplyment techniques 30 September 2010 Slide 4 f 19

5 1. Features Intrductin Features is Drupal a mdule that: Allws t exprt cnfiguratin items frm the Drupal DB int cde. Allws t imprt cde int cnfiguratin in the DB. Has a prly chsen name... Drupal versin cntrl and deplyment techniques 30 September 2010 Slide 5 f 19

6 1. Features Intrductin Many things can be exprted / imprted: views, CCK cntent types, CCK fields, menus, blcks... Things are exprted int features. A feature is a flder with cde files, similar t a mdule. A feature can cntain different types f cnfiguratin items (e.g. 2 cntent types with their fields, and 3 views).

7 1. Features Exprtables Exprtables are things that can be mved 100% t cde: Views Imagecache presets. Ctls: Panels and OpenLayers Rules Blcks (with help f Cntext mdule) Variables (with help f Strngarm mdule). Drupal versin cntrl and deplyment techniques 30 September 2010 Slide 7 f 19

8 1. Features Faux-exprtables Faux-exprtables: cannt be mved but can be synchrnized: CCK (better with Features+Strngarm mdules): Cntent types Fields Field grups Rles & Permissins Menus Vcabularies (but nt its terms) Ndes, terms and users: experimental state. Faux-exprtables can be verriden in the DB, and the Features mdule keeps track f it. Drupal versin cntrl and deplyment techniques 30 September 2010 Slide 8 f 19

9 1. Features Benefits Helps rganizing a cmplex prject. Exprted features can be versin cntrlled. features can be shared with ther peple. features can be deplyed. features can be hsted in a feature server features help upgrade frm Drupal 6 t Drupal 7. features can be reused between prjects. If a site admin verrides a feature and smething breaks, yu knw why. Drupal versin cntrl and deplyment techniques 30 September 2010 Slide 9 f 19

10 1. Features Integratin with drush drush: cmmand line tl fr Drupal: drush dl: dwnlad cre. drush dl cck views: dwnlad cntributed prjects. drush en cntent views: enable mdules. drush cc (all): clear cache. Integratin with Features mdule: drush fl : list all the features in a site. drush fu : update the cde f the features frm the changes made the the DB. drush fr : revert the DB back t the cde state. Drupal versin cntrl and deplyment techniques 30 September 2010 Slide 10 f 19

11 1. Features Hw t use Install and enable Features, Strngarm and CTls mdules (CTls is a dependency f Strngarm). In admin/build/features, create a feature by selecting what cmpnents t include in it Add the cntent type befre adding CCK fields. We btain a.tar.gz file. Unzip it int sites/all/mdules f anther site. In admin/build/features f the ther site, enable the feature and the cmpnents are created. Drupal versin cntrl and deplyment techniques 30 September 2010 Slide 11 f 19

12 1. Features DEMO 2 sites: develpment and prductin Sites have CCK, Views, Features, Strngarm installed. A CCK cntent type with fields and a cuple Views already created. We exprt them int a feature. We imprt the feature in anther site. Drupal versin cntrl and deplyment techniques 30 September 2010 Slide 12 f 19

13 1. Features Cnclusin Apply versin cntrl t features t keep track f changes in yur Cntent Types, Views... drush helps: use drush fu t autmatically update a feature's cde befre cmmitting. Use features t deply changes frm develpment t prductin withut squashing the cntent. git is recmmended as VC system, but nt cmpulsry (used by CDS, Indic and thers).

14 2. Other tls & techniques Cntrller feature / mdule Sme changes cannt be exprted t features, e.g. enabling / disabling mdules. Technique: we write an empty mdule / feature and we implement the hks: hk_install hk_uninstall hk_update_n Used by ther devs when they update frm the versin cntrl rep. N is incremental: hk_update_6001, hk_update_ Drupal versin cntrl and deplyment techniques 30 September 2010 Slide 14 f 19

15 2. Other tls & techniques Installatin prfiles Cde that gets executed when Drupal gets installed with install.php. Declares which mdules are active. Custm cde: initial cnfiguratin, interactin with the admin. Used t build distributins. Drupal versin cntrl and deplyment techniques 30 September 2010 Slide 15 f 19

16 2. Other tls & techniques Makefiles and drush make Drupal makefile: flat text file that declares what a Drupal site is made f (i.e. a manifest): mdules, themes, features, patches..make files get executed by drush make Useful fr: Knwing what is exactly n a site. Building / rebuilding a site. Applying versin cntrl t the.make file instead f the whle drupal flder. Drupal versin cntrl and deplyment techniques 30 September 2010 Slide 16 f 19
