I was playing around with cake php v.12. I run the cake php blog tutorial and everything went just fine. Then I tried to create another table and add a new page. And I encountered the following message: Error: Database table test for model Test was not found. After checking and rechecking that I followed the naming convention for all the files and classes I discovered that there are some files caching the database model in app\tmp\cache\models. I just delete them and everything works just fine. Just remember when you do some database changes in your schema to clean the cache.
