Hey All,

I’m just starting out w/rails & have a toy app w/just 2 types of  
things right now: People and Organizations. Person :belongs\_to  
organization and Organization :has\_many people.

I’ve got scaffold-generated index views for both, which work well  
(thanks in part to the kind help I’ve already gotten here). The index  
page for organization shows the # of people that currently belong to  
each one, and I even got fancy and made that number a hyperlink to the  
people/index, w/view code like so:

 \<%= link\_to organization.people.count, "People", :action =\> :index %\>

Now I want to get even fancier, and have people/index show me _just_  
people belonging to the organization whose link was clicked. So I  
figured I’d need to pass the people controller the proper organization  
id, and have it do a proper Person.find() call.

I got the impression from the AWDWR book that I could just tack on an  
extra hash value on my link\_to call to pass the parameter, so I edited  
the above to say:

 \<%= link\_to organization.people.count, "People", :action =\> :index, :org\_id =\> organization.id %\>

And then put this in PeopleController.index:

```
if params[:org_id] then
  # raise("params[:org_id] IS defined!")
  @people = Person.find_by_organization(params[:org_id])
else
  @people = Person.find(:all)
end

```

But it seems that my parameter is _not_ getting passed. If I dump a  
params.inspect to the index page I see:

{“action”=\>“index”, “controller”=\>“people”}

Soooo… can anybody tell me the right way to move a parameter from  
one page to another?

Thanks!

-Roy

Your problem here is that if you pass 2 parameters to link\_to like  
that, it’s going to assume that the first is some text and that the  
second is the url (or part of it)

Sure enough–that fixes it. Thanks!
