Colin, I added a layout file that had gone missing and now it validates. The html;
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en"> <head> <meta http-equiv="content-type" content="text/html;charset=UTF-8" /> <title>Orves: edit</title> <link href="/stylesheets/baby.css?1270578037" media="screen" rel="stylesheet" type="text/css" /> </head> <body> <p style="color: green"></p> <h1>Editing orf</h1> <form action="/orves/1705" class="edit_orf" id="edit_orf_1705" method="post"><div style="margin:0;padding:0"><input name="_method" type="hidden" value="put" /></div> Gura_0317 <input id="orf_current_annotation" name="orf[current_annotation]" size="50" type="text" value="hypothetical protein" /> <input id="orf_submit" name="commit" type="submit" value="Update" /> </form> </body> </html> And the validation report: HTML Validator 0 errors, 0 warnings The validated page has no errors, no warning found by the SGML Parser and HTML Tidy. But it still doesn't update the database. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
