Rails search/checkbox logic

I am trying to create some search function.

I do want users to be able to check checkboxes.

When the form submitted the 开发者_开发知识库ID of the companies should be send as params to a given URL.

In my controller i need to create some search action, I just dont know how to params are gonna be.

def search
@companyies = Company.find(find all the companies that match the params)'
end 

How should I create the checkbox loop? How should I create the search action?

Regarding the use of check boxes, this might be of some help to you.

Instead of rolling your own search system, you may have better luck using something like searchlogic that does most of this for you.
