Raul,
I do have a scaffolded 'Album' and I also have a Controller called
Albums. The controller called Albums should of been called Admin but
as far as I can tell, there is no way to build scaffold around a table
without using that table name as the default for all your files. I do
not think this is possible in Rails 2.1 where as in the old rails you
could use - scaffold :album
Correct me if I'm wrong the only reason when I clicked on destroy and
it was'nt redirecting me to the action that I wanted it to is because
in my AlbumsController there is
def destroy
@album = Album.find(params[:id])
@album.destroy
respond_to do |format|
format.html { redirect_to(albums_url) } ******* I think this
may of been the reason why it was picking up another action, is this
right in thinking so?
format.xml { head :ok }
would this override what I have in my PublicController?***********
end
end
Just one more question Raul how did you know that I had a
scaffold :album?
Thanks
Keith
