I am creating automated tests for my rails app using rspec and factoryBot. In my case I am creating a company with a requirement of having a logo. Creating a company in the test is not a problem but if I try and modify the company outside of the test file I am getting an error message of 

ActiveRecord::RecordInvalid:
   Validation failed: Logo can't be blank

I have tried alternative upload methods but with no luck. Below is the factory for the company and the process I am using to create a company. This is not the exact code in my implementation as I am unable to share that but I have replicated it as much as I could.

If I manually test the code it works fine. It is only when running the code with rspec the error occurs.

factories.rb

FactoryBot.define do
  factory :company do
    name { 'Name' }
    b_day { Date.today }
    age { 1 }
    logo { Rack::Test::UploadedFile.new(File.open(File.join(Rails.root, '/spec/support/logo.png')), 'image/png') }
  end
end

companies_rake_spec.rb

describe "Company b_day today" do
  it "Add 1 to company age" do
    company1 = create(:company)
    Rake::Task['companies:update_age'].invoke

    company1_refresh = Company.where(id: company1.id).first
    expect(company1_refresh.age).to eq(company1.age + 1)
  end
end

company.rake

namespace :companies do
  desc "TODO"
    task update_age: :environment do
       Company.find_each do | company |
          if (company.b_day.day == Date.today.day) && (company.b_day.month == Date.today.month)
            company.age += 1
            puts company.inspect
            company.save!
          end
       end
    end
  end
end

console

#<Company id: 34, name: "Name", b_day: 2018-11-13, age: 2, logo: "1cbeef36f13a8a88db0c37fa30da6ffd.png">

  • Where exactly does that error occur? Please provide the command you ran and the error message including the stacktrace. – spickermann Nov 13 '18 at 17:55
  • The command I ran was `rspec`. This called on a rake file which is included above. The point that error occurred was `company.save!`. I have added the stacktrace above – JackFurby Nov 14 '18 at 09:33

How to properly do model testing with ActiveStorage in rails?

Using the info from there and adapting to your specifics, try the following factory:

FactoryBot.define do factory :company do name { 'Name' } b_day { Date.today } age { 1 } after(:build) do |company| company.logo.attach(io: File.open(Rails.root.join('spec', 'support', 'logo.jpeg')), filename: 'logo.jpeg', content_type: 'image/jpeg') end end end

EDIT:

You may also need to add this to your config/environments/test.rb file:

config.active_storage.service = :test

  • Thank you for replying. Unfortunately, I think this will not work in my situation (I tried it and it just caused the same error when creating the company). One requirement in the model is for a logo to be present. If there is no fix I have tried to remove this requirement which words but ideally fixing the issue is preferred. – JackFurby Nov 13 '18 at 17:17
