Ich habe gerade auf ActiveStorage on Rails 5.1.4 umgestellt und bin neu in TDD. Ich habe Schwierigkeiten, herauszufinden, wie man ein Modell testen kann, das has_one_attached :avatar
require 'Rails_helper'
RSpec.describe User, :type => :model do
let (:valid_user) { FactoryBot.build(:user) }
describe "Upload avatar" do
context "with a valid image" do
it "saves the image" do
valid_user.save!
saved_file = valid_user.avatar.attach(io: File.open("/home/ubuntu/workspace/spec/fixtures/files/avatar.jpg"), filename: "face.jpg", content_type: "image/jpg")
expect(saved_file).to be_an_instance_of(ActiveStorage::Attachment::One)
end
end
end
end
Ich erhalte jedoch die folgende Fehlermeldung:
Failures:
1) User Upload avatar with a valid image saves the image
Failure/Error:
saved_file = valid_user.avatar.attach(io: File.open("/home/ubuntu/workspace/spec/fixtures/files/avatar.jpg"), filename: "face.jpg",
content_type: "image/jpg")
NoMethodError:
undefined method `upload' for nil:NilClass
Did you mean? load

Irgendwelche Hinweise?
Ich löste mich mit
FactoryBot.define do
factory :culture do
name 'Soy'
after(:build) do |culture|
culture.image.attach(io: File.open(Rails.root.join('spec', 'factories', 'images', 'soy.jpeg')), filename: 'soy.jpeg', content_type: 'image/jpeg')
end
end
end
Nach dem
describe '#image' do
subject { create(:culture).image }
it { is_expected.to be_an_instance_of(ActiveStorage::Attached::One) }
end
Problem gelöst. Nachdem ich den Fehler auf die ActiveStorage :: Blob :: upload-Methode zurückverfolgt hatte, sagte er: Uploads the io to the service on the key for this blob.
Ich erkannte, dass ich den active_storage.service nicht für die Testumgebung festgelegt hatte. Einfach gesagt, einfach hinzufügen:
config.active_storage.service = :test
In die Datei config/umwelts/test.rb
In config/environ/test.rb
config.active_storage.service = :test
In Ihrer Spezifikation
it {expect(valid_user.avatar).to be_attached}
