What is the error?

[jadewang425]

I'm not sure what I did but I can't see any options from the dropdown list anymore...

[jadewang425]

I got it back! here's the message

[asands94]

Can you also share the view.py thats responsible for adding an exercise. Did you add the exercise_id in the form.is_valid() section?

[jadewang425]

I'm not sure if using the form is the best way to go, but when I tried with the associate function similar to associating toy to a cat, it doesn't let me iterate the exercises for the dropdown list

[asands94]

If you print exercise_id are you getting a number back?

[jadewang425]

No, I'm not getting the number back and it doesn't print in the terminal as well.

[asands94]

Ok, then you may want to try adding in a bunch of exercises then associating them like we did with cats and toys using the assoc_toys method
