Hi Max, I am very new to this, but I think you''d need to
add :original_article_id to the params being submitted by the second
form. The params don''t stick around. I know the following works,
although I believe it is a beginner''s hack. To set up your add_link
form, run the following action. This creates a new Link object, sets
the correct original article id, and supplies this object to your
form.
def add_link
@link = Link.new
@link.original_article_id = params[:original_article_id]
end
in the second form, use a hidden field to hold this
<%= hidden_field ''link'',
''original_article_id'' %>
when the form gets submitted, this will be added to the params hash.
When you run the create_link action, it will get set correctly.
def create_link
@link = Link.new(params[:link])
if @link.save ...
