Django __小写 [英] Django __in lowercase

问题描述

我正在使用 django-taggit，它处理将标签附加到任意内容类型.我导入了一个大标签列表，其中包含许多大写单词和小写单词.

I'm using django-taggit, which handles the attachment of tags to arbitrary content types. I imported a large tag list, which contains many uppercase words, as well as lowercase words.

现在，我试图获取包含一组标签的另一个类的对象，但我想不区分大小写比较.当我这样做时:

Now, I' trying to get objects of another class containing a set of tags, but I want to compare case insensitively. When I do this:

Media.objects.filter(tags__name__in=['tag1', 'tag2'])

对象包含例如没有找到标签Tag1"，只有那些带有tag1"或tag2"的标签.

objects containing e.g. the tag "Tag1" are not found, only those ones with "tag1" or "tag2".

django orm 中是否有可能执行以下操作:

Is there any possibility in the django orm to do something like:

Media.objects.filter(tags__name__iin=['tag1', 'tag2'])

这就像图标"?

推荐答案

没有简单的方法可以做到.我不是 100% 确定，您可以尝试这样的方法来解决您的问题.

There is no easy way to do it. I'm not 100% sure, You can try something like this for your problem.

from django.models import Q

q = Q()
for tag in tags.split():
    q |= Q(tags__name__iexact=tag)

Media.objects.filter(q)
