implementing Customizing ActiveModel Serializers in Rails 7 for Conditional Attributes
I've looked through the documentation and I'm still confused about I'm working with a scenario with ActiveModel Serializers in Rails 7 where I want to conditionally serialize attributes based on user roles. I'm implementing a serializer for a `User` model and I've set up a few roles (e.g., `admin`, `user`). The scenario arises when I try to dynamically include or exclude certain attributes depending on the user's role. Here's the serializer code I'm currently using: ```ruby class UserSerializer < ActiveModel::Serializer attributes :id, :name, :email def attributes(*args) hash = super if scope && scope.admin? hash[:admin_only] = object.admin_specific_info end hash end end ``` In my controller, I'm trying to pass the current user as the `scope`, like this: ```ruby class UsersController < ApplicationController def show user = User.find(params[:id]) render json: user, serializer: UserSerializer, scope: current_user end end ``` However, when I test this, I'm getting the following behavior: ``` NoMethodError: undefined method `admin_specific_info' for #<User:0x00007fdc4c8e5f38> ``` This behavior suggests that the `admin_specific_info` method might not be defined or accessible in the User model for non-admin users. I've verified that `admin_specific_info` exists in the User model, and it returns a value for admin users. However, I'm unsure how to conditionally access this method without raising an behavior for non-admin users. I've tried adding checks in the serializer like this: ```ruby if object.respond_to?(:admin_specific_info) && scope.admin? ``` But that doesn't seem to resolve the behavior. Any suggestions on how to properly implement this conditional serialization without running into method access issues? Also, are there any best practices for handling such cases in ActiveModel Serializers? Is there a better approach? What am I doing wrong?
