Hey guys,
Lets say I have the following nested resources:
map.resource artists do |artists|
map.resource songs
end
To create a new song, the url would be:
/artists/:artist_id/songs/:song_id
However, lets say that an artist doesn''t exist yet. I only want to
create an artist if a new song by the artist is successfully saved. I
am retrieving the artist using something like:
@artist = find_or_intialize_by_country_id(@country)
Since the artist doesn''t exist yet, there will be no
''id'' attribute
yet. However, I have to pass in an id to the url which creates the
song, ie:
new_song_path(@artist)
This will obviously fail since @artist.id is nil. I can use
find_or_create_by instead, but then if the user cancels creating a
song, I will be left with an extra row in the artist table that I
don''t need.
Any ideas?
