Hi all,
I have a template that is sometimes given a local like so:
render :partial => ''shared/new_addresses'', :locals =>
{:addresses =>
addresses}
In the partial I do this to make sure everything is cool:
if defined? addresses && !addresses.nil? &&
addresses[:z_address]
@address = addresses[:z_address]
end
Now, here''s where things get weird. After the app has been running a
while in production I start getting exceptions being thrown due to
addresses being nil on the assignment line above. Even though I make
sure it isn''t in the if statement!
If I do this:
if defined? addresses && !addresses.nil? &&
addresses[:z_address]
if !addresses.nil?
@address = addresses[:z_address]
end
end
I don''t get the errors.
Any one have a clue as to what is happening here?
Cheers,
--Ed

You should use instead local_assigns.has_key? addresses You could also work aroud that by doing addresses ||= nil That way if it was undefined initially, it will be nil after that, so you can check it with addresses.nil? directly regards, javier ramirez -- -------- Estamos de estreno... si necesitas llevar el control de tus gastos visita http://www.gastosgem.com !!Es gratis!! --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

Thanks Javier! Using local_assigns.has_key? does the trick.
