Question

I have an app with three models:

Client

has_many :papers

Paper

has_many :pages
belongs_to :client

Page

belongs_to :paper

I can do this in code: @paper.client.name

But I am unable to do @paper.page.name NoMethodError is produced

What I am doing wrong? These are all nested models, where Client is at high level.

Answer 1

Your Paper object has many pages, so there’s no page method. If you want to get the names of all the pages belonging to a Paper object, you’ll need to iterate over the pages association:

for page in @paper.pages
    puts page.name
end
