Method: Hash#each_with_parent

Defined in:
lib/asana_exception_notifier/initializers/hash.rb

#each_with_parent(parent = nil, &block) ⇒ void

This method returns an undefined value.

This method is used for iterating over a Hash , but besides yielding the key and the value, this will also yield the parent key of the current Hash object if the Hash is associated to a key

Examples:

Printing a Hash that contains other hashes inside, and fetching the parent keys

hash = {
         key: :my_value,
         key2: {
           innner_key: :inner_value
         }
       }
 hash.each_with_parent { |parent, key, value| puts [parent, key, value].inspect }
 will print:
     [nil, :key, :my_value]
     [:key2, :innner_key, :inner_value]

Parameters:

  • parent (String, nil) (defaults to: nil) —

    The parent key of the current level of the Hash ( first level of any Hash has no parent, but if the hash has a value which is also a Hash, the parent of that value will be the key associated to the value )

  • &block (Proc) —

    The block which will be used to yield the parent string, the current key and the value, while the Hash is being iterated over
