文档仅显示将文件附加到模型(http://edgeguides.rubyonrails.org/active_storage_overview.html#attaching-file-io-objects)的方法。
灯具如何?
在模型中使用has_one_attached :file
时,我尝试了键file
和file_attachments
,但是它不起作用。
我是否必须为ActiveStorage::Attachment
和/或ActiveStorage::Blob
明确创建灯具文件?
答案 0 :(得分:2)
在测试中,我发现必须使用fixture_file_upload
进行附加。这是RSpec中的2个示例,但是我相信fixture_file_upload
方法也应在minitest中起作用。关键是在顶部包含ActionDispatch::TestProcess
(除非您使用的是minitest,否则我认为不包含include即可使用)。
附件文件保存在:spec / fixturs / files / filename.gif
附件的型号规格
require 'rails_helper'
include ActionDispatch::TestProcess
RSpec.describe Whatever, type: :model do
it 'is valid/invalid depending on file presence' do
file = fixture_file_upload(Rails.root.join('spec/fixtures/files', 'parrot.gif'), 'image/gif')
expect(SomeClass.new(an_attribute: 'something', file: file)).to be_valid
expect(SomeClass.new(an_attribute: 'something').to be_invalid
end
end
请求规范
require 'rails_helper'
include ActionDispatch::TestProcess
RSpec.describe "whatever", type: :request do
file = fixture_file_upload(Rails.root.join('spec/fixtures/files', 'parrot.gif'), 'image/gif')
describe 'POST on whatever controller' do
it 'saves the record when a file is attached' do
expect{
post whatever_path, params: { params: { file: file } }
}.to change { WhateverModel.count }.by(1)
end
end
end
