Unfortunatley有否 __ iin 字段查找。但是有一个 iregex 可能是有用的，像这样：

  result = Name.objects.filter（name__iregex = r' （name1 | name2 | name3）'）
 

甚至：

  a = ['name1'，'name2'，'name3'] 
 result = Name.objects.filter（name__iregex = r'（'+' |'.join（a）+'）'）
 

请注意，如果一个可以包含特别是正则表达式，您需要正确逃离他们。 / p>

新闻：在Djano 1.7中，可以创建自己的查找，所以你可以实际使用 filter（name__iin = ['name1'，'name2 '，'name3']）。请参阅 https://docs.djangoproject.com/en/1.7/ref/models / lookup / 。

I have a list of names that I want to match case insensitive, is there a way to do it without using a loop like below?

a = ['name1', 'name2', 'name3']
result = any([Name.objects.filter(name__iexact=name) for name in a])

Unfortunatley, there are no __iin field lookup. But there is a iregex that might be usefull, like so:

result = Name.objects.filter(name__iregex=r'(name1|name2|name3)')

or even:

a = ['name1', 'name2', 'name3']
result = Name.objects.filter(name__iregex=r'(' + '|'.join(a) + ')')

Note that if a can contain characters that are special in a regex, you need to escape them properly.

NEWS: In Djano 1.7 it is possible to create your own lookups, so you can actually use filter(name__iin=['name1', 'name2', 'name3']) after proper initialization. See https://docs.djangoproject.com/en/1.7/ref/models/lookups/ for details.
