Hello, everyone:
     I tried the html option (multipart) to upload an image to
server , but the form_for always errors. If I remove the html option,
it works. I have no idea the reason, looks like it is only a syntax
error, but couldn''t figure it out.
    Thanks a lot in advance!

============<% form_for([@task, @comment]), :html => {:multipart =>
true} do |f|
%>

Comment body
    <%= f.text_area :desc %>

<label
for="comment_image">Image
    <%= file_column_field ''comment'',
''image'' %>

    <%= f.submit button_name %>

<% end %>
