Hello to all,
I''m confronted to a quite simple problem (I hope so):
In a rhtml file I''m using the following code to make a select from a
act_as_tree Model:
<%= select_tag("input_region",
options_for_select(Region.find(:all,
:order => "name").collect {|c| [ " " *
c.ancestors.size + c.name,
c.id ]})) %>
But the generated output is:
<select id="input_region" name="input_region">
<option value="4">&nbsp;Asia </option>
<option value="7">&nbsp;Australia</option>
<option value="2">&nbsp;Europe</option>
<option
value="3">&nbsp;&nbsp;France</option>
<option value="5">&nbsp;North America</option>
<option value="6">&nbsp;South America</option>
<option value="1">World</option></select>
As you can see the is converted to escape html special
chars( => &nsbp;). How can I prevent rails to convert html
chars ?
Thx in advance for your answers.
++ Jerome

I think the string is passing through the h funtion. I don''t know how to prevent it. I could rewrite de options_for_select but I''m pretty sure there''s an alternative.

Apparently, the html_escape code in Rails/Erb/Most projects I have ever seen, assumes (rightly or wrongly) that your input will NOT have ANY markup''s already converted inside it. The trick is to make the html_escape somewhat more tolerant. The code I would suggest would be something like this; irb(main):014:0> s="this is test" => "this is test" irb(main):015:0> s.gsub(/(&+(?!amp;))/,"&") => "this is &nbsp; test" irb(main):016:0> s.gsub(/(&+(?!amp;)(?!lt;)(?!gt;)(?!quot;)(?!nbsp;))/,"&") => "this is test" Of course, you probably want to fling that into an ''override'' for your application (eg; application.rb) something along the lines of; def html_escape(s) s.to_s.gsub(/(&+(?!amp;)(?!lt;)(?!gt;)(?!quot;)(?!nbsp;))/,"&").gsub(/\"/, """).gsub(/>/, ">").gsub(/</, "<") end I assume that if you fling it in there, everything will be good with the world. You may have to deal with re-declaring the alias and the module_functions again, no idea. Take with a pinch of salt (or vinegar if your that perverse). Hopefully you get the idea. You could always update the erb.rb file that I believe is the main ''culprit'', and you could submit a patch to the Erb maintainer. You get the idea, share the wealth etc etc :) Sorry for the rambling incoherent-ness of this message, I have only had my second cup of coffee so far :) Regards Stef --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
