Revision: [2025] A little more work on plugin to set some default routing. Revision: [2024] Changed DboSource::field() so the name() is not called for some field variables. Revision: [2023] Changes made in [2022] should only check if the $conditions is not empty. Revision: [2022] Changed DboSource::conditions() so it will add the "ticks" needed around the Model.field names. The Model.field name conventions must be used for this to work. Revision: [2021] Adding fix for Ticket #405 Revision: [2020] Added fix for Ticket #403 Revision: [2019] Added patch from Ticket #404. Fixing formatting of files. Revision: [2018] Fixing formatting of files Revision: [2017] Fixed bad search and replace Revision: [2016] Fixing formatting of files Revision: [2015] Replaced all 3 space indents with 4 space indents Revision: [2014] Updating variables to use the naming proper conventions Revision: [2013] Added patch from Ticket #406 Revision: [2012] Adding fix for Ticket #407. Fix variables that where not formatted per the coding conventions Revision: [2011] Adding patch from Ticket #401 git-svn-id: https://svn.cakephp.org/repo/trunk/cake@2026 3807eeeb-6ff5-0310-8944-8be069107fe0
