Class Method Summary

::ActiveSupport::InheritableOptions - Inherited

::Hash - Inherited

.from_trusted_xml

Builds a ::Hash from XML just like Hash.from_xml, but also allows ::Symbol and YAML.

.from_xml

Returns a ::Hash containing a collection of pairs when the key is the node name and the value is its content.

#assert_valid_keys

Validates all keys in a hash match *valid_keys, raising ArgumentError on a mismatch.

#blank?

A hash is blank if it’s empty:

#compact_blank!

Removes all blank values from the ::Hash in place and returns self.

#deep_dup

Returns a deep copy of hash.

#deep_merge

Returns a new hash with self and other_hash merged recursively.

#deep_merge!

Same as #deep_merge, but modifies self.

#deep_stringify_keys

Returns a new hash with all keys converted to strings.

#deep_stringify_keys!

Destructively converts all keys to strings.

#deep_symbolize_keys

Returns a new hash with all keys converted to symbols, as long as they respond to to_sym.

#deep_symbolize_keys!

Destructively converts all keys to symbols, as long as they respond to to_sym.

#deep_transform_keys

Returns a new hash with all keys converted by the block operation.

#deep_transform_keys!

Destructively converts all keys by using the block operation.

#deep_transform_values

Returns a new hash with all values converted by the block operation.

#deep_transform_values!

Destructively converts all values by using the block operation.

#except

Returns a hash that includes everything except given keys.

#except!

Removes the given keys from hash and returns it.

#extract!

Removes and returns the key/value pairs matching the given keys.

#nested_under_indifferent_access
#reverse_merge

Merges the caller into other_hash.

#reverse_merge!

Destructive reverse_merge.

#reverse_update
#slice!

Replaces the hash with only the given keys.

#stringify_keys

Returns a new hash with all keys converted to strings.

#stringify_keys!

Destructively converts all keys to strings.

#symbolize_keys

Returns a new hash with all keys converted to symbols, as long as they respond to to_sym.

#to_options
#to_options!
#to_param

Alias for Hash#to_query.

#to_query

Returns a string representation of the receiver suitable for use as a URL query string:

#to_xml

Returns a string containing an XML representation of its receiver:

#with_defaults
#with_defaults!
#with_indifferent_access

Returns an ::ActiveSupport::HashWithIndifferentAccess out of its receiver:
