Active Admin No Method error in foreign key relationship - ruby-on-rails

Question

I am making a notes app using Active Admin for the first time and I am running into an error that confuses me because the relationship exists my migrations are present as far as I can see in the schema. I have 2 models currently Note that belongs_to Content and Content has_many :notes . I am trying to customize my show for Contents so it will display differently as seen below but I keep getting a no method error for notes this relationship is present and should work as it is a foreign key between both tables?
class Note < ApplicationRecord
belongs_to :content
end
class Content < ApplicationRecord
has_many :notes
end
ActiveAdmin.register Content do
permit_params :name, note_ids: []
show title: 'Test' do
h3 'You have ' + pluralize(content.notes.count, 'note') + ' referencing ' + `#{content.name}`
end
ActiveRecord::Schema.define(version: 2021_05_06_140826) do
# These are extensions that must be enabled in order to support this database

Are you sure that content is ActiveRecord object? It looks like it is instance of ActiveSupport SafeBuffer.
