As part of CO-112, COmanage Registry v0.4 migrated from CakePHP 1.3 to 2.05. The full description of everything that changed in CakePHP 2 is available at http://book.cakephp.org/2.0/en/appendices/2-0-migration-guide.html. Reading only this COmanage wiki page is not a substitute for reviewing the migration guide in the CakePHP book.

* Denotes a change being made concurrent with the CakePHP 2 migration that is not required by CakePHP 2.

All Files

• Drop ?> closing tag in .php files*
• Switch to docbook style* (See Coding Style Guide)
• Throw exceptions for error handling (rarely – this should only be done when a proper error can't be rendered via setFlash() or a REST HTTP return code)
• Scope functions and variables (ie: public $requires_co)
• Joins no longer needs dbo full table name (see various examples, including UsersController:login)

Models

• Models need all fields defined in validate() for REST API*
• Models need public version set*

Views

• $html is no longer available, use $this->Html instead
• Use $cur_co to get coid for forms (do not directly examine params submitted by user)*
• When generating a select, the format for calling has changed (see any examples in various {{fields.inc}}s)
• select() needs manual display of error: $this->Form->isFieldError
• fieldsErrorToString is no longer used
• Paginator arguments 1 and 2 swapped

Controllers

• Use $this->request->is('get') to determine render form vs process data
• Drop $components from controllers (now in AppController)
• Change include App.standard_controller to use Uses instead
• $this->data becomes $this->request->data; don't write to either
• $this->params becomes $this->request->params
• Changed params for checkWriteDependencies and checkWriteFollowups*
