How to include user's image in Post instance
I have a view that returns me every post, what I'm trying to do is include the user's avatar image with the post.
Serializer
class PostSerializer(serializers.ModelSerializer):
class Meta:
model = Post
fields = '__all__'
View
@api_view(['GET'])
def getPost(request):
post = Post.objects.all().order_by('-date_posted')
serializer = PostSerializer(post, many=True)
return Response(serializer.data)
User Model
class User(AbstractBaseUser):
email = models.EmailField(verbose_name="email", max_length=60, unique=True)
username = models.CharField(max_length=30, unique=True)
avatar = models.ImageField(default='default.jpg')
Post Model
class Post(models.Model):
author = models.ForeignKey(User, on_delete=CASCADE)
trade = models.CharField(max_length=100)
trade_description = models.TextField(null=True)
How can I make it so that when the view returns me the post, it also includes the associated user's avatar image as well? The User's avatar field just holds a link to an amazon s3 bucket that hosts the image
There is two ways
1. Nested serializer
It gives you nested response
Declare a serializer for user, then include it in your post serializer:
class UserSerializer(serializers.ModelSerializer):
class Meta:
model = User
fields = ('avatar', ...)
class PostSerializer(serializers.ModelSerializer):
author = UserSerializer()
class Meta:
model = Post
fields = '__all__'
2. Use source
It gives you flat response
class PostSerializer(serializers.ModelSerializer):
author_avatar = serializers.ImageField(source='author.avatar')
class Meta:
model = Post
fields = ('author_avatar', ...)
