Rails inclusion validation failure

Question

I have a model that contains two integer columns representing start_time and end_time . These times are represented by the minute offset for that day.

class Example < ActiveRecord::Base
    validates :start_time, inclusion: 0..1440
    validates :end_time,   inclusion: 0..1440
end

I also have a factory

FactoryGirl.define do
    factory :examples do
        start_time { Kernel.rand(1441) }
        end_time   { Kernel.rand(1441) }
    end
end

When I build this object and check if it's valid with RSpec I get errors relating to the start_time and end_time not being in the list. Checking the values of the object shows that they are properly in range.

I have tried the following to get it to work.

inclusion: { in: 0..1440 }
inclusion: [0..1440].flatten

---EDIT

In RSpec

let(:example_klass) { FactoryGirl.build(:example) }
expect(example_klass).to be_valid ##=> FAILS

In rails console

t = FactoryGirl.build(:example)
t.valid?
=> true

Any help would be appreciated!

Answer 1

Use

FactoryGirl.define do
    sequence :start_time , (0..1441) do |n|
        n   
    end
    sequence :end_time   , (0..1441) do |n|
        n   
    end 
end

and in your Example Factory use

FactoryGirl.define do
    factory :examples do
        start_time 
        end_time
    end
end

Anything refer to the documentation: https://github.com/thoughtbot/factory_girl/wiki/Usage#sequences-and-associations .

Hope this helps
