Hi! Is there a (simple) way to use alternative field names in validation messages? For example, if I have a validator like this one: validates_presence_of :email how can I make it print a message like "E-Mail Address can''t be blank" instead of "Email can''t be blank"?

Hi, how can I get the current URL withing a controller? There seems to be no appropriate method in ActionController::Base. I''m creating a site, which requires a login for some pages.

Hi all: I can''t make redirect_to to unlock the current iframe using {:TARGET => "_top"}. It always stays in the current frame. I checked the redirect_to code, it seems the method does not use "target". here is the source code of redirect_to from ActionController::Base def redirect_to(options = {}, *parameters_for_method_reference) #:doc: 753: case options

Hi guys, I was wondering if you are able to have a link_to_remote, having an image_tag and the link_to_remote has a mouseover event that updates a div. Does the image_tag need the mouseover event? I currently have: <%= link_to_remote(image_tag(@p_image.public_filename(:thumb)), :update => "big_pic", :onmouseover => {:action => :color_change, :id => @p_image.id})%>

How can I pass something to set_table_name so that I can switch tables on the fly for accessing archive data?
