python - django 将查询集转换为列表数组

Question

如何将返回的 QuerySet 转换为字符串数组？

myWords = MyGroup.objects.get(name = "bla").allkeyword
# to
myWords = ["meltemi", "bla"]


class MyGroup(models.Model):
    name = models.CharField(max_length=32, unique=True)
    allkeyword = models.ManyToManyField('KeywordTag')
    def __unicode__(self):
        return '%s' % (self.name)

class KeywordTag(models.Model):
    name = models.CharField(max_length=32, unique=True)
    def __unicode__(self):
        return self.name

Answer 1

您可以使用 values_list() :

myWords = MyGroup.objects.get(name = "bla").allkeyword.values_list('name', flat=True)
