Transcript

  • 1. Drupal 8 in action, the route to the method @juanolalla #DrupalCampEs
  • 2. about.me/juanolalla Juan Olalla web developer focused on drupal at @ideup (@gowex) Motivation I’ve recently been contributing to Drupal 8 core and I want to share with you what I've learned
  • 3. Wellcome to Drupal 8 Routing
  • 4. Goodbye to hook_menu()
  • 5. Goodbye to hook_menu() for routing and for everything else... Routing Routes defined in routing.yml and controllers Menu links Defined in hook_default_menu_links() Local actions Plugins defined in local_actions.yml Local tasks Plugins defined in local_tasks.yml Contextual links Plugins defined in contextual_links.yml Breadcrumbs Implementing BreadcrumbBuilder plugins Links can be related regardless of the path, managed by machine names.
  • 6. Drupal 8 uses Symfony2 Routing component And also uses Symfony CMF RoutingBundle for dynamic routing
  • 7. What is a route?
  • 8. A route is an object defined by 1. Path 2. Default values 3. Requirements 4. Options 5. Host 6. Schemes 7. Methods
  • 9. ueSmoyCmoetRuigRue s yfnopnnotnot; $ot =nwRue rue e ot( 'acie{ot},/ pt /rhv/mnh' / ah ary'otolr = 'hwrhv',/ dfutvle ra(cnrle' > soAcie) / eal aus ary ra( 'ot'= '09{}[-]2' mnh > [-]4-09{}, 'udmi'= 'w|' sboan > wwm, ) / rqieet , / eurmns ary) / otos ra(, / pin 'sboan.xml.o' / hs {udmi}eapecm, / ot ary) / shms ra(, / cee ary)/ mtos ra( / ehd ) ;
  • 10. The Routing component gets routes from • PHP code: • a RouteCollection object • closures • class annotations • External files: • YAML • XML • PHP
  • 11. Drupal 8 uses YAML to define routes foacie o.rhv: pt:'acie{ot} ah /rhv/mnh' dfut: eals _otn: cnet 'DuaootolrFootolr:hwrhv' rplfoCnrleoCnrle:soAcie rqieet: eurmns mnh '09{}[-]2' ot: [-]4-09{} sboan 'w|' udmi: wwm hs:'sboan.xml.o' ot {udmi}eapecm
  • 12. Let’s start with a plain “hello world” using a /hello-world path
  • 13. Defining the route in YAML /modules/foo/foo.routing.yml fohlowrd o.el_ol: pt:'hlowrd ah /el-ol' dfut: eals _otolr cnrle: 'DuaootolrFootolr:elWrd rplfoCnrleoCnrle:hlool' rqieet: eurmns _ces 'RE acs: TU'
  • 14. Creating the controller /modules/foo/lib/Controller/FooController.php nmsaeDuaootolr aepc rplfoCnrle; ueSmoyCmoetHtFudtoepne s yfnopnntponainRsos; casFootolr{ ls oCnrle pbi fnto hlool( { ulc ucin elWrd) $epne=nwRsos(HloWrd'; rsos e epne'el ol!) $epne>edr-st'otn-ye,'etpan) rsos-haes>e(CnetTp' tx/li'; rtr $epne eun rsos; } }
  • 15. HloWrd el ol!
  • 16. Drupal 8 will use PSR-4 for module classes instead of PSR-0 /modules/foo/lib/Controller/FooController.php instead of /modules/foo/lib/Drupal/foo/Controller/FooController.php drupal.org issue: https://drupal.org/node/1971198
  • 17. Returning a JSON response nmsaeDuaootolr aepc rplfoCnrle; ueSmoyCmoetHtFudtosnepne s yfnopnntponainJoRsos casFootolr{ ls oCnrle pbi fnto hlool( { ulc ucin elWrd) rtr nwJoRsos( eun e snepne ary'reig = 'el Wrd' ra(getn' > Hlo ol!) ) ; } }
  • 18. {getn""el Wrd" "reig:Hlo ol!}
  • 19. Returning "hello world" inside Drupal content using a /hello-world path
  • 20. Defining the route in YAML fohlowrd o.el_ol: pt:'hlowrd ah /el-ol' dfut: eals _otn: cnet 'DuaootolrFootolr:elWrd rplfoCnrleoCnrle:hlool' _il:'reig tte Getn' rqieet: eurmns _emsin 'cescnet priso: acs otn'

  • 22. What about dynamic page titles? drupal_set_title() is being removed Use _title_callback in the route defaults dfut: eals _il_alak tteclbc: 'DuaootolrFootolr:eTte rplfoCnrleoCnrle:gtil' Or return it as part of the main render array $ul[#il' =.. bid'tte] .
  • 23. Returning a "hello world" greeting configuration form at /admin/config/people/greeting
  • 24. Defining the route in YAML foamngetn: o.di_reig pt:'amncni/epegetn' ah /di/ofgpol/reig dfut: eals _om 'DuaoomFoom fr: rplfoFroFr' rqieet: eurmns _emsin 'diitrgetn' priso: amnse reig

  • 35. Access Check _o_hl_o_as TU yusalntps: RE
  • 36. Drupal 8 doesn't implement Symfony2 Security component, and manages access from routing Symfony uses a separate Security component for controlling route access that is too complex to integrate in Drupal 8. Drupal 8 implements access checkers services, which will ignore, allow or deny the access based on a requirement on the route.
