Description

ORM doesn't support 'in' lookups for DateField/DateTimeField fields.

Example from test:

class Article(models.Model):
    headline = models.CharField(max_length=100)
    pub_date = models.DateTimeField()
    class Meta:
        ordering = ('-pub_date', 'headline')

    def __unicode__(self):
        return self.headline

Article.objects.filter(pub_date__in=[datetime(2005, 7, 26), datetime(2005, 7, 28)])

And it produces wrong SQL:

('SELECT `lookup_article`.`id`, `lookup_article`.`headline`, `lookup_article`.`pub_date` FROM `lookup_article` WHERE `lookup_article`.`pub_date`
 IN (%s, %s, %s, %s, %s, %s, %s, %s, %s, %s, %s, %s, %s, %s, %s, %s, %s, %s, %s, %s, %s, %s, %s, 
%s, %s, %s, %s, %s, %s, %s, %s, %s, %s, %s, %s, %s, %s, %s, %s, %s, %s, %s, %s, %s, %s, %s, %s, %s, %s, %s, %s, %s,
 %s, %s, %s, %s, %s, %s, %s, %s, %s, %s, %s, %s, %s, %s, %s, %s, %s, %s, %s, %s, %s, %s, %s, %s)
ORDER BY `lookup_article`.`pub_date` DESC, `lookup_article`.`headline` ASC',
 (u'[', u'd', u'a', u't', u'e',u't', u'i', u'm', u'e', u'.', u'd', u'a', u't', u'e', u't', u'i', u'm', u'e',
 u'(', u'2', u'0', u'0', u'5', u',', u' ', u'7', u',', u' ', u'2', u'6', u',', u' ', u'0', u',', u' ', u'0', u')', u',', u' ', 
u'd', u'a', u't', u'e', u't', u'i', u'm', u'e', u'.', u'd', u'a', u't', u'e', u't', u'i', u'm', u'e', u'(', u'2', 
u'0', u'0', u'5', u',', u' ', u'7', u',', u' ', u'2', u'8', u',', u' ', u'0', u',', u' ', u'0', u')', u']'))

#7448 already covers this, I believe.

My solution is better and has test case.

And I pointed to your patch and noted it had a testcase over in #7448. There is only one problem here, we don't need multiple tickets for it. If you want to argue for your specific way of fixing the problem, please do so over in #7448.

Ok. Thanks.

and similar complex objects.

Based on patches from cgrady and alexkosholev. Refs #7707.
