Question

I have a Position model for which I have a scope defined:

scope :default, where('is_default = ?', 1)

Idea being that I want to know which is the default position. I can do something like: @profile.positions.default and this returns an activerecord relation and the default position record. The issue is that now that I have the default record, I need to access other attributes of Positions such as title..

@profile.positions.default.title 

but the above returns an error: NoMethodError: undefined method `title’ for #

Any clues? Thanks.

Answer 1

A scope turns a collection of objects, not a single object, so you’re trying to call title on an array of ActiveRecord results.

You probably want something like this:

@profile.positions.default.first.title

Or if you always want just one record, you may switch from a scope to a class method:

def self.default
  where('is_default = ?', 1).first
end
