Hi, I seem to remember seeing the equivalent of saving only if all attributes are different. I can''t seem to find that now in the API or the agile book.

When I create a new record, it is added to the spares table however the list action does not show all the columns in the table. It only shows those columns that are not foreign keys. I am using the default action generated by scaffold for list. Why is that so? Do i need to re-write my

I looked everywhere but couldn''t find it. I don''t want a submit_tag or image_submit_tag but a normal link that submits my form. Normally I would do this with a javascript like function sendForm () { document.forms[0].submit(); } but this doesn''t work with form_remote_tag link_to_function( ''Send'' , "sendform();") So the question is:

Hello Railists, I have a piece of Ruby on Rails code that has a complex SQL query (well, not that complex, but as far as I know beyond the ORM capabilities) and for my taste it has too many strings and harcoded values.

This is driving me crazy because all the login engines/generators respond to an authentication error with a redirect_to. The work around is to change them to all do a render :layout => false, :status => 500
