What do you mean, "it forgets to add any information about the first
one"? I don't understand what you are trying to say there.

You are aware that links should be GET requests and not POST requests,
right? GETs should be safe.

http://www.w3.org/2001/tag/doc/whenToUseGet.html

Also you should think about "Progressive Enhancement" and what happens
when people do not have have Javascript available. Using :method
requires Javascript to create a form on the fly in memory. It is just
a normal GET otherwise.

But as to your problem, I am not sure. It works for me. I just
jigged up a test case of your example and I was able to use that same
syntax just fine.

I suggest enclosing the link_to with parenthesis. That can sometimes
enable the error to be more visible with a different ruby message.

<%= link_to("create", foos_path(@foo, :bar_id => @bar.id), :method => :post) %>

Not sure but a shot in the dark. Make sure the parameter is a string
with to_s.

<%= link_to("create", foos_path(@foo, :bar_id => @bar.id.to_s), :method => :post) %>

Are you including default Javascript libraries? IIRC that is needed.
Not sure though.

<%= javascript_include_tag :defaults %>

Good luck!
