I’ve just made my first form using select boxes that update each other
via observe_field. It works really well for the creation of record and
it’s making the form a whole lot nicer to use.
The problem is editing records, the first select box is not part of the
model but is used to populate the second select, which is a required
attribute of the model. When the edit form is displayed, the second box
is blank (as the first needs to be selected) and so you have to manually
change it before you edit anything else and submit the form.
I’m hoping there’s some clever trick I haven’t even thought of that
could make this work. Ideally, when the form is displayed, id like it to
get set the first select box based on the contents of the second, and
then set the second to the models attribute.
I’m not sure if I’m explaining this very well so please don’t hestitate
to shout for more info. I’d be very grateful to know how to get around
