How to upload a file in a Rails Rspec request spec

问题

I want to test uploading a file in a Rails Rspec request test. I'm using Paperclip for asset storage.

I've tried:

path = 'path/to/fixture_file'
params = { file: Rack::Test::UploadedFile.new(path, 'application/pdf', true) }
post v1_product_documents_path, params: params

In the controller, I get a string

"#Rack::Test::UploadedFile:0x0055b544479128>"

instead of the actual file.

The same code works in controller tests

回答1:

try to use fixture_file_upload: fixture_file_upload

or if you wanted to use this in a factory

 Rack::Test::UploadedFile.new(File.open(File.join(Rails.root, '/spec/fixtures/images/bob-weir.jpg')))

回答2:

Under describe block, include these modules

include Rack::Test::Methods
include ActionDispatch::TestProcess

Now try running the specs

path = 'path/to/fixture_file'
params = { "file" => Rack::Test::UploadedFile.new(path, 'application/pdf', true) }
post v1_product_documents_path, params: params

Also, I guess you forgot to add , between v1_product_documents_path and params: params, please add that and let me know.

Hope that helps!

In rails_helper.rb do

include ActionDispatch::TestProcess
include Rack::Test::Methods

Then you have few options. 1. You can use fixture_file_upload helper

  let(:file) { fixture_file_upload('files/image.jpg') }
  it 'it should work' do
    post some_path, params: { uploads: { file: file } }
  end

You can use Uploaded file but you have to give full path

  let(:file) { Rack::Test::UploadedFile.new(Rails.root.join('spec',
  'fixtures', 'blank.jpg'), 'image/jpg') }
  let(:params) { { attachment: file, variant_ids: ['', product.master.id] } }
  let(:action) { post :create, product_id: product.slug, image: params }

回答4:

Might be useful for other users: I got this problem because I mistakenly used a get instead of a post request in my specs.

回答5:

For rails 6 no need to do includes, just fixture_file_upload. If you are using spec/fixtures/files folder for fixtures you can use file_fixture helper

let(:csv_file) { fixture_file_upload(file_fixture('file_example.csv')) }

subject(:http_request) { post upload_file_path, params: { file: csv_file } }
