How to pass an array IN via GET?

Howdy.

I'm not sure what the right way to do this is. I basically need to pass an array in via GET to my controller action.

For a little background, here's what's going on from the user's perspective:

User clicks some checkboxes in my YUI DataTable, thereby marking some rows. User then clicks something that causes me to gather up a list of the selected items, then set those as a new request for another DataTable.

My controller gets these request params, builds a conditions list, and fetches records from my model.

For example, my URL would be something like this: /my_controller/my_action?group=users&limits=dog,cat,bird

Then in my_action(), I want to use params[:limits] in conjunction with my_model.find(:all, :conditions => { [animal in (?)], params[:limits] } )

(My syntax may be off in my example, but hopefully my goal is clear.)

Thanks!

Sure, it’s easy. Just append your parameter with empty brackets ():

<%= check_box_tag ‘limit’, ‘dog’ %> <%= check_box_tag ‘limit’, ‘cat’ %>

Your URL will end up looking like:

/my_controller/my_action?group=users&limits=dog&limits=cat&limits=bird

And params[:limit] will be an array.
