# flat_hash returns a flattened hash, a hash with a single level of
|
|
# depth in which each key is composed from the keys of the original
|
|
# hash (whose value is not a hash) by typing in the key of the route
|
|
# from the first level of the original hash
|
|
#
|
|
# Examples:
|
|
#
|
|
# hash = {
|
|
# 'key1' => 'value1',
|
|
# 'key2' => { 'key3' => 'value2',
|
|
# 'key4' => { 'key5' => 'value3' } }
|
|
# }
|
|
#
|
|
# I18nContent.flat_hash(hash) = {
|
|
# 'key1' => 'value1',
|
|
# 'key2.key3' => 'value2',
|
|
# 'key2.key4.key5' => 'value3'
|
|
# }
|
|
#
|
|
# I18nContent.flat_hash(hash, 'string') = {
|
|
# 'string.key1' => 'value1',
|
|
# 'string.key2.key3' => 'value2',
|
|
# 'string.key2.key4.key5' => 'value3'
|
|
# }
