python - Django 多对多字段

Question

在我的模型中我有:

class Poll(models.Model):
    topic = models.CharField(max_length=200)
    tags = models.ManyToManyField(Tag)

我正在尝试创建 Poll 对象并像这样存储标签:

Tags = []
for splitTag in splitTags:
    tag = Tag(name = splitTag.lower())
    tag.save()
    Tags.append(tag)

如何设置 Tags 数组并将其分配给 tags？

我试过:

    poll = Poll(topic=topic, tags = Tags)
    poll.save()

Answer 1

嗯，应该更像这样:

models.py

class Tag(models.Model):
    name = models.CharField(max_length=200)

class Poll(models.Model):
    topic = models.CharField(max_length=200)
    tags = models.ManyToManyField(Tag)

in views.py:

poll = Poll(topic="My topic")
poll.save()
for splitTag in splitTags:
    tag = Tag(name = splitTag.lower())
    tag.save()
    poll.tags.add(tag)
poll.save()
