django-orm 不区分大小写的顺序 [英] django-orm case-insensitive order by

问题描述

我知道，我可以从 DJango ORM 运行不区分大小写的搜索.喜欢，

I know, I can run a case insensitive search from DJango ORM. Like,

User.objects.filter(first_name__contains="jake")
User.objects.filter(first_name__contains="sulley")
User.objects.filter(first_name__icontains="Jake")
User.objects.filter(first_name__icontains="Sulley")

而且，我可以将它们获取为

And also, I can fetch them as

user_list = User.objects.all().order_by("first_name")
# sequence: (Jake, Sulley, jake, sulley)
user_list = User.objects.all().order_by("-first_name") # for reverse
# sequence: (sulley, jake, Sulley, Jake)

是否有不区分大小写的提取的直接方法?就像我想要一个序列一样

Is there a direct way for a case-insensitive fetch?? As in I want a sequence as

# desired sequence: jake, Jake, sulley, Sulley

如果没有，那么建议一个最好的方法来做到这一点.提前致谢.

If not, then suggest a best way to do it. Thanks in advance.

我找到了使用 .extra 的解决方案

I found solution using .extra

class MyModelName(models.Model):
   is_mine = models.BooleanField(default=False)
   name = models.CharField(max_length=100)


MyModelName.objects.filter( is_mine=1 ).extra(
    select={'lower_name':'lower(name)'}).order_by('lower_name')
