I am developing a rails app, more or less a car database.
The interresting part of the model is this :
Country (has_many) <-> (belongs_to) Car maker (has_many) <->
(belongs_to) model etc. But some categories are off this dependency
relationship, as for instance, Vintage, motors,…
The problem I am facing is making a new.rhtml file. More precisely, this
kind of apps needs whether:
- not to show the model until the country and the car maker have been
- (optional) the upper categories are automatically set when a sub
category is selected. For example : US - Ford appear when Mustang is
selected in the form.
I’ve got a couple of books on rails I work on, but non goes on this
I imagine that Ajax will be part of the answer and yet nothing like this
has resulted so far on gg.
Any help most welcome!
