Active Model Serializers has_many association

#programming #rails

I always forget all the different ways of serializing associations things, so putting down notes:

has_many

class AuthorSerializer < ActiveModel::Serializer
has_many :posts
emd

This will embed a array of post records into the author record.

{
"authors": {
"posts": []
}
}

has_many, embed :ids

class AuthorSerializer < ActiveModel::Serializer
has_many :posts, embed: :ids
emd

This will embed post_ids and sideload the posts:

{
"posts": [],
"authors": {
"post_ids": []
}
}

attribute

class AuthorSerializer < ActiveModel::Serializer
attributes :post_ids
emd

This will only embed the post_ids.

{
"authors": {
"post_ids": []
}
}
