The following is simply for testing and educational purposes:
def new
if request.get?
@album = Album.new(:artist_id => params[:artist])
else
@album = Album.new(params[:album])
if @album.save
flash[:notice] = "Album successfully added. Add a Song"
redirect_to :controller => ''song_admin'', :action
=> ''new'',
:album => @album
else
flash[:notice] = "Failed to add Album"
flash[:error_field] = :album
end
end
end
Once the album is saved, it redirects to allow the user to add a song to
the album. On the album form, I have a field: "no_songs" as an
integer.
I want the redirect to happen as many times as specified in the
"no_songs" column.
I''m not sure what syntax to use here.

Do you mean that you only want to redirect if the number of songs in the album is less than no_songs? If so then just test album.songs.size against params[:no_songs]. -- Posted via http://www.ruby-forum.com/. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

For example: I add an album and set ''no_songs'' to 7. Upon update, it redirects me to add a song to the album using parameters. I only want this redirect to occur 7 times as I''ve told the system that there are only 7 songs in the album. -- Posted via http://www.ruby-forum.com/. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

If it is then that''s all the attempts used up, if not then increment it and re-render the page, setting the field from the variable. This is kind of a horrible way of doing things, why not just put space for seven (or whatever) songs on the form in the first place?

I''m picking it up easy enough, I guess.This doesn''t really teach you about associations though, it just teaches you how to do a really horrible application design :) A more useful way to use the associations is to look at the extra methods given to you by the associations, which allow you to add seven songs to an album at once for example. -- Posted via http://www.ruby-forum.com/. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

I know what you mean about using more appropriate methods to do this, I was just querying that particular method.
