Django queryset filtering












0














I have 2 main entities in my models.py:



class IPGroup(models.Model):
name = models.CharField(max_length=50, unique=True)
address = models.CharField(max_length=50, unique=True)

class Tag(models.Model):
name = models.CharField(max_length=100)
value = models.CharField(max_length=100)


These two tables are linked through a 3rd through table as follows:



class IPGroupToTag(models.Model):
ip_group = models.ForeignKey(IPGroup)
tag = models.ForeignKey(Tag)


My requirement is to find all the tags with the name "SecurityZone" when the only input I have is the name of the IPGroup. My attempt is as follows:



ip_group_id = IPGroup.objects.get(name="test_ip_group").id
zone = IPGroupToTag.objects.filter(ip_group_id=ip_group_id).values('tag__name')


which gives me the following Queryset:



<QuerySet [{'tag__name': 'Title'}, {'tag__name': 'Site'}, {'tag__name': 'SecurityZone'}, {'tag__name': 'DataCenter'}, {'tag__name': 'Pod'}]>


How do I then find the id of the tag with the name SecurityZone and then find its value
