Revision: [2629] Fixed recursive associations when set to 0, did not add the hasOne or belongsTo in the query. Changed scaffold to use recursive setting of 0 in all methods that call Model::findAll() Fixed Invalid argument supplied for foreach() notice in show.thtml Removed 500 record limit in Controller::generateFieldNames() Revision: [2628] Merging changes from model_php5.php Revision: [2627] Fixing messed up characters in dbo_odbc, adding docstrings, and giving connect() a return value Revision: [2625] Bringing all DB drivers up to date Revision: [2624] Changed fixed for Ticket #609 so and empty array is set instead of null. This is more consistent with the other arrays that are returned if an association is found Revision: [2623] Adding fix for Ticket #712 git-svn-id: https://svn.cakephp.org/repo/trunk/cake/1.x.x.x@2630 3807eeeb-6ff5-0310-8944-8be069107fe0
