I have this weird problems where I have a mysql DB with tables called
tutors
tutorsold
lessons

I renamed tutors table and called it tutorsold. The cakephp code when saving now picks up the table called tutorsold and not the table tutors which i imported from somewhere else. I have all the same structure for both tutors table.

This is a mysql problem and not a coding error.

I get a cant delete table error as has a FK field etc

No where in the code do i refer to this tutorsold table. In fact I cant delete anything from this table tutorsold.

So remove the foreign key then delete the table either in a GUI or...

alter table tutorsold drop foreign key fk_classes_tutors1

Open in new window

i see the referential constraint in information Scheme (phpmyadmin) as a referenced tablename of tutorsold when it should be just tutors.

How can I change this?

Drop the old one and create a new one on tutors
I don't remember the exact steps in PHPMyAdmin - Alter Structure or something.

You need to remove foreign key as detailed above.
Or remove it in PHPMyAdmin under Table Structure > Links To
