I don't know if this is possible, but I think it would highly useful if it were.
Basically, I want to filter a DateField as though it were a string (see the StackOverflow post <http://stackoverflow.com/questions/36191609/how-can-i-filter-django-datefield-using-a-string> to understand why) If there was an option on a Q filter like this: Q(field__icontains="data", *T**ypeCheck=False*) ^^^^^^^^^^^^^^^^^^ (instructing Django to bypass type checking for this field) it would then be possible to do *datatype conversion on the database level*, allowing code like this to work from django.db.models import Lookupfrom django.db.models.fields import DateField @DateField.register_lookupclass DateTextFilter(Lookup): lookup_name = 'dttxt' def as_postgresql(self, compiler, connection): lhs, lhs_params = self.process_lhs(compiler, connection) rhs = self.rhs.strftime("%b %d, %Y") # this would be replaced by a partial date. e.g., 'Mar 05' return "to_char(%s,'Mon DD, YYYY') ~* '%s'", ([lhs,rhs]) Currently, this causes a ValidationError ValidationError: [u"'Mar 09' value has an invalid date format. It must be in YYYY-MM-DD format."] -- You received this message because you are subscribed to the Google Groups "Django developers (Contributions to Django itself)" group.
