Inheritance in Rails - I need some help
I''ve got a model, "category" and another model "subcategory." Each
subcategory belongs_to a category, and a category has_many
subcategories.
What I need to do is set it up so that I can search Category and
Subcategory with one .find call. So:
Category.find(:all, <etc)
will find categories and subcategories.

and subcategories (which themselves belong_to a category). What I''m

AJAX - how to have multiple select form sets implemented?
hi, there :)
Consider a blogging application whereby a user is trying to add a new
blog.
He/she has to select a category. Upon selecting a category from a drop
down box, a new sub categories drop down box will be created (hence an
AJAX call). Got this implemented and it''s ok.
Now, let''s assume that a given blog can have multiple categories (and
subcategories).

Dropdown list to populate drag and drop sortable list
I''m listing bands playing shows. I want to be able to add and sort the
lineup for each show in a single form. Users select a band playing
from a dropdown list, which (using Ajax) adds the band to an unordered
list which they can then re-arrange.
Are these any tutorials online that cover this? Or can anyone shed any
light on it?

I have something that somewhat works, but I think there is probably a

includes something as simple as making a dropdown that jumps to the link
when selected without needing a "submit" button. I see a bunch of AJAX
effects and draggable-element stuff, but all i need is a simple
dropdown... should I code it myself?
