i need to pull out some specific values from a nested hash, but nils
are driving me crazy. in the following example, if address_details,
country, administrative_area, locality OR postal_code are nil i get
“The error occurred while evaluating nil.[]”
zip = placemark[‘address_details’][‘country’][‘administrative_area’]
[‘locality’][‘postal_code’][‘postal_code_number’]
i tried
unless placemark[‘address_details’][‘country’][‘administrative_area’]
[‘locality’][‘postal_code’][‘postal_code_number’].nil?
but if anything above postal_code_number is nil i still get the error.
i could check each level but that is really ugly.
is there a easy way to check if postal_code_number exists?
