I''m trying to build an WebFTP application in Rails for some practice.
Here is a link located in a partial named _display_file that is called
by a partial named _list_files. A similar link is created for every
directory in the FTP
<%= link_to_remote filename ,
:url => {:action => ''chdir'' ,
:ftp_dir => filename},
:update => ''ftp_div'' %>
It should, to my understanding, make a call to the ''chdir''
action and
use the results to update the ftp_div.
The controller action ''chdir'' is shown below:
def chdir
@ftp = session[''ftp'']
@ftp.chdir( params[ :ftp_dir ] )
session[''ftp''] = @ftp
@list = @ftp.list("-a")
end
btw, I can store the ftp object inside a session because I''ve enabled
memory_cache instead of other session types. So that''s not the issue,
it works without the AJAX.
Finally the file chdir.rjs is shown below:
page.replace_html("ftp_div" , :partial => "list_files" ,
:object =>
@list)
So basically, the user should be able to click on the directory and the
directory listing should be updated without a page refresh. Instead I
get this error when click on one of the links:
RJS error:
TypeError $(element) has no properties
Afterwords I get a "notice" box containing what appears to be the
code
I would like to appear in the ftp_div division... It looks something
like this:
Element.update("ftp_div", "<!-- Start FTP List table -->
<table border=\"1\">
etc...
with the etc... being replaced by the content that should be showing in
the browser. Any suggestions would be appreciated.

Any suggestions would be appreciated.Joe, I had the same problem before, and turns out that when you''re using RJS templates you shouldn''t specify the :update on your link_to_remote, so on your case you just call <%= link_to_remote filename, :url => {:action => ''chdir'' , :ftp_dir => filename} %> Hope that helps. -- Thiago Jackiw acts_as_solr => http://acts-as-solr.rubyforge.org -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

Unfortunately the problem persists after removing the update tag.

One thing you might check is to ensure that the tag <div id=''ftp_div''> appears once, and *only* once, in the html page you''re producing. hth, Bill --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

I had <div class="ftp_div"> instead of id="ftp_div". I changed it and all is well.
