year/month/day/hour/minute/second filters in django-rest-framework -

i've defined django-rest filter this:

created_date = django_filters.datetimefilter(     lookup_type=["year", "month", "day", "hour", "minute", "second", "lt", "lte", "gt", "gte"])

this url proper query: created_date < 2015-05-01:

the same thing works gt for: created_date > 2015-05-01:

this url proper query: created_date > 2015-05-01

however, when try query on year:

typeerror: int() argument must string or number, not 'datetime.datetime'

i tried

and same error. idea how year/month/day/hour/minute/second filters working?

datetimefilter filter converts input value datetime, created_date__year compared datetime , wrong. has compared int.

solution 1:

add filter same field:

created_date_part = django_filters.numberfilter(     name='created_date',     lookup_type=["year", "month", "day", "hour", "minute", "second"])

however need create name field.

solution 2:

write custom filter inherit charfilter , validation itself.
