Looking now I’ve learned something new again. I recently renamed some fields in one of the tables in my database. I also made the necessary changes to the model file (refactoring) for that table in order to avert any unexpected results in my application.
So I tested the application locally to ensure there were no glitches and then committed and pushed my changes to the live repository.
But to my utmost dismay – it broke! My application was no longer functioning in one part. Next thing that came to mind was to delete the files in the tmp/cache/models to be sure the table structure wasn’t cached.
Yet, no joy. Now I was thinking of going into the Cakephp core library to find out why this thing was still using an old cached copy of the database table.
Looking through the Model.php file I noticed the caching was still based on the files in the tmp directory which I had deleted.
Finally, I decided to take one more swipe at the tmp directory this time deleting the files in both the tmp/cache/models and tmp/cache/persistent directories.
Alas! All the errors were gone. Now I’ll always remember to delete the files here manually of write an addon to do just that after modifying my database structure.
