I refactored tz_extra API. To get the list of time zones you have now two functions:
TzExtra.time_zone_identifiers/1TzExtra.civil_time_zone_identifiers/1
The latter will only return the time zones attached to a country. For example, it will not return the “Etc/GMT+6” time zone. Both functions take some options, and note that the previous option names have been changed.
I also added Ecto Changeset validators:
validate_civil_time_zone_identifier/3validate_time_zone_identifier/3validate_iso_country_code/3
Example:
import TzExtra.Changeset
def changeset(location, attrs) do
location
|> cast(attrs, @required_fields ++ @optional_fields)
|> validate_required(@required_fields)
|> validate_iso_country_code(:country_code)
|> validate_civil_time_zone_identifier(:time_zone)
end
