I want to make every line in a doc in-place-editable.  
rails 2.2.2

routes.rb  
map.resources :docs do |poem|  
poem.resources :lines  
end

view-server-side  
new Ajax.InPlaceEditor(‘line\<%=line\_number +1%\>’, ‘\<%= doc\_line\_path  
(:doc\_id =\> @doc.id,:id =\> line\_number) %\>’);

view-client-side  
new Ajax.InPlaceEditor(‘line5’, ‘/docs/4/lines/4’);

log  
ActionController::MethodNotAllowed (Only get, put, and delete requests  
are allowed.)

if i change the doc\_line\_path to doc\_lines\_path  
view-client-side  
new Ajax.InPlaceEditor(‘line5’, ‘/docs/4/lines?id=4’)

log  
Processing LinesController#create (for 127.0.0.1 at 2009-01-24  
13:10:52) [POST]

what i want is LinesController#update.  
why the url ‘/docs/4/lines/4’ can not be mapped to the “update”  
action of LinesControlelr?  
Is it a defact of rails2.2.2?  
waiting for you help.
