How to handle multiple JSON responses in Rails 7 with custom serializers correctly?
I'm wondering if anyone has experience with I've been researching this but I've been banging my head against this for hours. I'm optimizing some code but I'm relatively new to this, so bear with me. I've been banging my head against this for hours. I'm currently working on a Rails 7 API project where I'm using ActiveModel Serializers to customize the JSON responses for my models. I have two models, `User` and `Post`, where a user can have many posts. I want to serialize the user along with their posts in a specific format, but I'm running into issues when trying to nest the posts within the user JSON response. Here’s the code for my serializers: ```ruby # app/serializers/user_serializer.rb class UserSerializer < ActiveModel::Serializer attributes :id, :name, :email has_many :posts, serializer: PostSerializer end # app/serializers/post_serializer.rb class PostSerializer < ActiveModel::Serializer attributes :id, :title, :content end ``` When I attempt to render a user like this: ```ruby # app/controllers/users_controller.rb def show user = User.find(params[:id]) render json: user, serializer: UserSerializer end ``` I get the following unexpected output: ```json { "id": 1, "name": "John Doe", "email": "john@example.com" } ``` I expected to see the posts nested within the user response, something like: ```json { "id": 1, "name": "John Doe", "email": "john@example.com", "posts": [ { "id": 1, "title": "First Post", "content": "This is my first post." } ] } ``` I’ve tried several things, including checking if the `posts` association is correctly set up in the `User` model: ```ruby # app/models/user.rb class User < ApplicationRecord has_many :posts end ``` I also ensured that `ActiveModelSerializers` is included in the Gemfile. After confirming that, I ran `bundle install` to make sure all dependencies are up to date. Additionally, I tried explicitly loading the associated posts in the controller like this: ```ruby user = User.includes(:posts).find(params[:id]) ``` However, the output remains the same. I suspect there might be an issue with how the serialization is being triggered or perhaps some configuration that I’ve overlooked. Any insights or suggestions on how to properly include the nested posts in the JSON response would be greatly appreciated! For context: I'm using Ruby on Linux. How would you solve this? I'd really appreciate any guidance on this. Cheers for any assistance! The project is a microservice built with Ruby. Any help would be greatly appreciated! I'm developing on CentOS with Ruby. Any ideas what could be causing this?
