How to return data with all ForeignKey?

Im new to DRF. There are two models like:

class Article(models.Model):
    title = models.CharField(max_length=100, unique=True)

class ArticleTag(models.Model):
    article = models.ForeignKey(
        Article, on_delete=models.CASCADE, related_name='tags')
    tag = models.CharField(max_length=100)

I want the backend to return data like:
[{ title : 'Article1', tags : [ 'tag1', 'tag2' ]},{ title : 'Article2', tags : [ 'tag2', 'tag3' ]} ... ]

Is this possible? I have no idea how to combine data from different models.

See the docs page at Serializer relations - Django REST framework
There are examples on that page showing what you’re trying to do.

I get it, thank you!
