Author: phpnut Date: 2:11:57 PM, Saturday, November 05, 2005 Message: Fixing Controller::generateFieldNames() to work with changes to Model [1334] Author: phpnut Date: 1:18:02 PM, Saturday, November 05, 2005 Message: More work on changes made in the model to allow association names to be used as an alias. These changes are being made to update scaffold to work with changes in [1330]. Added var $alias that holds an array with the key value pair of the table name and the association name. [1330] Author: phpnut Date: 10:25:16 PM, Friday, November 04, 2005 Message: Adding fix for Ticket #127. The query returns properly now but, this breaks scaffold which I will be fixing soon. Also the save methods for the model have not been tested but I am sure these need to be corrected also. git-svn-id: https://svn.cakephp.org/repo/trunk/cake@1336 3807eeeb-6ff5-0310-8944-8be069107fe0
