Hi
A photo-app I'm working on has tags on an image defined as a many to many
relationship:
class Image(models.Model):
filename = models.CharField(maxlength=255)
description = models.TextField()
tags = models.ManyToManyField(Tag)
Given several tags: TagA, TagB, ..., I'm trying to find images that
contain each of the tags.
I try this:
In [73]:Image.objects.filter(tags__id=1).filter(tags__id=2)
Out[73]:[]
However, I know images with both of those tags exist, eg:
In [73]:i = Image.objects.filter(tags__id=1)[0]
In [74]:i
Out[74]:<Image: 2004-09-23++14-10-03_++_dsc_5994.jpg>
In [75]:[tag.id for tag in i.tags.all()]
Out[75]:[1, 2, 3, 17, 170, 259, 362, 387, 414, 647, 681, 810]
How can I find the image(s) with a given set of tags?
Thanks
Neilen
