belongs_to has_many newbie question

I've searched alot tonight for this answer, it must be out there, so
thanks for any help.

I have a simple setup like so:

LIST
  has_many :list_items
  has_many :business, :through => :list_items

LIST_ITEM
  belongs_to :list
  belongs_to :business

BUSINESS
belongs_to :list_items ...?

So I have busineses on my website. Now I've made some lists, that
have list items (which are businesses).

1. Is belongs_to list_items ok for my model above?
2. If i'm in the business controller viewing a business, how can i
see what lists that business is listed in? So in my view in business,
i want to show 'this business is listed in list X, list Y, etc.'.

Thanks for any help!

Hi --

I've searched alot tonight for this answer, it must be out there, so
thanks for any help.

I have a simple setup like so:

LIST
has_many :list_items
has_many :business, :through => :list_items

Plural: has_many :businesses, etc.

LIST_ITEM
belongs_to :list
belongs_to :business

BUSINESS
belongs_to :list_items ...?

That should be has_many :list_items. I think you'll also want
has_many :lists, :through => :list_items

So I have busineses on my website. Now I've made some lists, that
have list items (which are businesses).

1. Is belongs_to list_items ok for my model above?

No -- see above.

2. If i'm in the business controller viewing a business, how can i
see what lists that business is listed in? So in my view in business,
i want to show 'this business is listed in list X, list Y, etc.'.

If you have a business object in the variable @business, and if you do
has_many :lists as above, then you can do:

   @business.lists

and that will give you a collection (array) of all the lists.

I kind of think that maybe you want businesses to have lists and to
have list_items through lists, rather than the other way around, but
I'm not sure. Anyway, you can follow the patterns here. The goal is to
make it easy to get the information from the objects you've got.
