having problems since recreating my database

Question

I have a controller on my Api folder named CrudsController and I have this function. what I don't understand is this is properly working before I had issues with my database that I had to recreate. Now I'm getting this error message:

Missing Method in CrudsController Error: The action api_add is not defined in controller CrudsController

I tried editing it to public function api_add. but after that this is the error I'm getting. I just want it to work the way it did before
