Nothing obviously wrong so I'll guess something obscure...
have you
added an inflection rule telling Rails that 'news' is
uncountable (like
fish, it uses the same for singular and plural)? Check the
end of
/config/environment.rb. You'd uncomment in the inflection
rules at the
end with the result looking like:
Inflector.inflections do |inflect|
inflect.uncountable %w(fish sheep news)
end
Just wondering if Rails is getting confused over the
has_many/belongs_to relationship between :news and :user.
Also, you might want to check your News.find_recent method.
As written
it appears that it will always return the first ten news
items created
and return them in reverse order. Instead you probably want
the db to
return the last ten stories created:
class News < ActiveRecord::Base
...
def self.find_recent
News.find(:all, :order => 'created_at DESC', :limit
=> 10)
end
end
Good luck,
