Form Fields

TimeZoneField

class djem.forms.TimeZoneField(**kwargs)

A TypedChoiceField with defaults applied for coerce and choices.

• Default widget: Select.

• Empty value: '' (the empty string), by default.

• Normalizes to: a TimeZoneHelper instance.

• Validates that the given value exists in the list of choices and can be coerced.

• Error message keys: required, invalid_choice.

coerce

Defaults to a function that accepts a timezone name string (‘Australia/Sydney’, ‘US/Eastern’, etc) and returns a TimeZoneHelper instance for that timezone.

choices

Defaults to a list of 2-tuples containing the timezones provided by pytz.common_timezones. Both items of each 2-tuple simply contain the timezone name. This is equavalient to:

choices = [(tz, tz) for tz in pytz.common_timezones]

Note

Use of TimeZoneField requires pytz to be installed. If pytz is not available, the default choices list will be empty and no TimeZoneHelper objects will be able to be instantiated.

Note

Use of TimeZoneField only makes sense if USE_TZ is True.
