FactoryGirl Error "define_method': tried to create Proc object without a block (ArgumentError)"

Question

Here is my Lesson Factory i-e lesson.rb

FactoryGirl.define do
  factory :lesson do |lesson|
   lesson.sequence(:title) { |n| "title#{n}" }
   lesson.sequence(:description) { |n| "description#{n}" }
   lesson.sequence(:transcript) { |n| "transcript#{n}" }
   association :course, strategy: :build
  end
end

Here is my lesson_spec.rb file

require 'spec_helper'

describe Lesson do
  before { let(:lesson) { FactoryGirl.create(:lesson) } }
  subject (:lesson)
  it { should validate_presence_of :title    }
end

Any Help? Thanks in advance!!!

Answer 1

you don't need the before statement in the before block.

before { let(:lesson) { FactoryGirl.create(:lesson) } }

change to this

let(:lesson) { FactoryGirl.create(:lesson)

Answer 2

Simple you dont needed let in before, either you would use before or let i would prefer to use let, have look at this answerexplainin when to use let and when to use before.

require 'spec_helper'

describe Lesson do
  let(:lesson) { FactoryGirl.create(:lesson) }
  subject (lesson)
  it { should validate_presence_of :title    }
end

Answer 3

I did i this way and it works

require 'spec_helper'

describe Lesson do
  subject { FactoryGirl.create(:lesson) }
  it { should validate_presence_of :title    }
