I basically want to know whether there is such function on ruby on rails
that allows me to duplicate a record but have the primary keys changed.
For example, duplicate 20 records of Micheal Jackson’s address and
details but the primary keys will be 1 to 20, I need this function for
my database, is there something like this with a click of a button or a
link, also a flash message that could tell me that i am on record number
6 or 18 or 19 etc, thanks.
if your model is Article then
your original article is in @article_to_copy
@copy = Article.create(@article_to_copy.attributes)
works with new, too

so my model is Artist, so in the artist new controller i should add:
@artist_to_copy = Artist.create(@artist_to_copy.attributes)
@artist = Artist.new(artist_to_copy.attributes)
what do i put in the view I have not got alot of knowledge of HTML as i
am still learning your answer would be welcomed thanks…

no,
@artist_to_copy = Artist.find( your find conditions, eg id )
so you have the artist you want to copy
then either
@artist = Artist.create(@artist_to_copy.attributes)
OR
@artist = Artist.new(@artist_to_copy.attributes)
@artist.save

in the view you simply put a link to your action, show your artists or
whatever
the link should hand over all necessary information to find the artist,
your response should render the new state. sorry, but i can’t go into
much more details here (i don’t know, what you want to show your users)
maybe this will help you to get the basics:
I have done all of this and it come back with an error:
ActiveRecord::RecordNotFound in ArtistsController#new

very funny,
@artist_to_copy = Artist.find( your find conditions, eg id )
must get an id, of course. like:
@artist_to_copy = Artist.find(1)
or
@artist_to_copy = Artist.find(params[:id])
if id was sent as param with the url
please read some tutorial that gives you at least an overview of basic
RoR functionality
