Hi all, Is there a function/method that does the reverse of h() ? I need to decode some html-entities-encoded string back to the actual characters, e.g. "&" to "&", and so on. By the way, I couldn''t find the documentation for h() in the Rails API docs, is it not part of Rails? Where should I look for its docs? I thought maybe I could find the reverse function in the docs. Thanks in advance. Cheers, Ronny _______________________________________________ Rails mailing list Rails-1W37MKcQCpIf0INCOvqR/iCwEArCW2h5@public.gmane.org http://lists.rubyonrails.org/mailman/listinfo/rails
h() is just an alias for html_escape, but that doesn''t seem to be showing up in the docs. Unfortunately I can''t tell you how to reverse h()...but it seems like you might be using it wrong (or I''m using it wrong, so I''d like to be corrected!). I was under the impression that it''s just used for sanitizing output before it''s sent to the browser, so it would be done in a controller or view. It sounds to me like you''re calling h() when you insert something into the database, which is unnecessary and you''ll end up running into the problems you have. That may not be your particular situation, but it''s a comment I have that may help other people avoid misusing h() in this manner.

I want to do an inline text editing with AJAX (a la Flickr). Maybe I''m not doing it right, or just complicating things. So my asking this is just out of curiosity really.

Did anybody succeeded in using InPlaceEditing inside a partial collection?
It''s working perfectly in a regular template, but the id part becomes
blank when it''s inside a partial collection.
article_controller.rb:
class ArticleController < ApplicationController
in_place_edit_for :comment, :body
...
end
_comment.rhtml:
<li id="comment-<%= comment.id %>">
<%= in_place_editor_field :comment, :body %>
</li>
show.rhtml:
....
<ol id="comments">
<% unless @article.comments == nil %>
<%= render :partial => "comment", :collection =>
@article.comments %>
<% end %>
</ol>
....
Generated HTML:
....
<li id="comment-21">
<span class="in_place_editor_field"
id="comment_body__in_place_editor"
tag="span"></span><script
type="text/javascript">
//<![CDATA[
new Ajax.InPlaceEditor(''comment_body__in_place_editor'',
''/article/set_comment_body'')
//]]>
</script>
....
[comment_body__in_place_editor] should be [comment_body_21_in_place_editor].
Apparently, the id is not set properly.
More odd thing is that when a comment is added using AJAX, above code
is working again.
I also tried to include :id as follows:
<%= in_place_editor_field :comment, :body, { :id => comment.id } %>
But in this case, [comment_body__in_place_editor] only becomes [21],
but not [comment_body_21_in_place_editor]
Here are the docs for InPlaceEditing:
http://rails.rubyonrails.com/classes/ActionController/Macros/InPlaceEditing/ClassMethods.html
http://rails.rubyonrails.com/classes/ActionView/Helpers/JavaScriptMacrosHelper.html#M000367
What am I missing here?
