Exception: Ohm::Model::IndexNotFound

Inherits:
Error show all
Defined in:
lib/ohm.rb

Overview

Raised when you try and do an Set#find operation and use a key which you did not define as an index. 

  class Post < Ohm::Model
    attribute :title
  end

  post = Post.create(:title => "Ohm")

  ex = nil
  begin
    Post.find(:title => "Ohm")
  rescue Exception => e
    ex = e
  end

  ex.kind_of?(Ohm::Model::IndexNotFound)
  # => true

To correct this problem, simply define a :title index in your class. 

  class Post < Ohm::Model
    attribute :title
    index :title
  end
