remote form_tag in rails3 without a named route

Question

what is the proper incantation to make this actually post asynchronously?

form_tag :controller => :magic, :action => :search, :method => post, :remote => true do

method=post and remote=true just get squashed on the end of the url instead of actually making it an ajax post.

Answer 1

I believe you need to use form_remote_tag instead:

form_remote_tag(:url => { :controller => :magic, :action => :search }) do

The default http method is post.

If you do want to pass extra parameters on a form_tag you need to make them into a separate hash from the url parameters, like this:

form_tag { :controller => :magic, :action => :search }, { :method => post, :remote => true } do

Answer 2

The only way I found to do it is to wrap the url parameters in the url_for method.

form_tag url_for(:action => :create, :id => @artist.id), :remote => true do 

However, if you need to the pass the method parameter you might need to wrap that and the remote in parentheses.
