Hi
I am seeing some corruption of a hash that I create in a .rhtml and then
pass in :params back to an action. In the .rhtml I do :-
<% @pp = { "t" => {"todo_id" => todo.id,
"position" => todo.position}}
%>
<td><%= link_to_image "note", :action =>
"list_edit", :id => todo.id,
:params => @pp %></td>
<td><%= debug @pp %></td>
The debug YAML looks OK:-
t:
todo_id: 23
position: 2
However the hash is corrupted when the list_edit action is executed :-
render_text @params.inspect
{"action"=>"list_edit",
"id"=>"23", "controller"=>"todos",
"t"=>"todo_id23position2"}
I would expect:-
{"action"=>"list_edit",
"id"=>"23", "controller"=>"todos",
"t"=>{"todo_id"=>"23",
"position"=>"2"}}
(The @pp tmp var is so that I can debug. It doesn''t change the result)
Thanks for any help
Peter

It doesn''t change the result)Actually, I think I see your problem. To the best of my knowledge Ruby doesn''t support serialising hashes through URLs, at least not automatically. Try marshalling it in to a string and then unmarshalling it. I don''t know how to do that, but it''s all in the Ruby manual. -- Phillip Hutchings http://www.sitharus.com/ sitharus-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org / sitharus-QrR4M9swfipWk0Htik3J/w@public.gmane.org
