问题描述

我正在使用 django-taggit ,它处理标签附加到任意内容类型。
我导入了一个大的标签列表,其中包含许多大写字母以及小写字母。



现在,我试图获取另一个类的对象一组标签,但是我想比较不区分大小写。当我这样做:

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

包含eg的对象没有找到标签Tag1,只有那些tag1或tag2的标签。



django orm中是否有可能执行以下操作: / p>

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



没有简单的方法可以做到。我不是100%肯定的,你可以尝试这样的问题。

 从django.models导入Q 

q = Q()
标签中的标签.split():
q | = Q(tags__name__iexact = tag)

Media.objects.filter(q )


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.

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'])

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

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

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

that acts like "icontains"?

解决方案

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)
