shrinerb / shrine-memory Goto Github PK

I'm not sure if I should be able to do this with the gem anyway. I am using Shrine memory for my test environment. I am trying to write a feature spec to check a process in which a user uploads a CSV, matches up the files headers and it processes it. I've setup shrine memory in the initialiser as below:

if Rails.env.test?
  require 'shrine/storage/memory'
  Shrine.storages = {
    cache: Shrine::Storage::Memory.new,
    store: Shrine::Storage::Memory.new,
  }
else

I am then adding a csv file in my factory which I want to use later in my controller. I run the FactoryGirl factory in my spec and it all seems to work fine. When inspecting it I get back a url of it in memory. However when I visit the page where I am matching up the headers of the csv file it fails. It says it is unable to find the file in memory. As I need to open the file to find out what the headers are.

Should/would the file created in the factory actually be accessible, if it is meant to be what am I doing wrong? If not is their a way I can force the model to point to a file I store somewhere else?

I'm using the shrine-imgix plugin in combination with S3 like so:

imgix = Shrine::Storage::Imgix.new(
  storage:          Shrine::Storage::S3.new(**s3_options),
  include_prefix:   true, # set to false if you have prefix configured in Imgix source
  api_key:          "xzy123",                 #
  host:             "my-subdomain.imgix.net", # Imgix::Client options
  secure_url_token: "abc123", # optional      #
)

Shrine.storages[:store] = imgix

I'm also using direct uploads with the presign_endpoint plugin.

As part of the upload process I show the user a preview of the image they are uploading, before they submit the form. I generate the URL of this image using the following code:

path = []
path << Shrine.storages[:cache].storage.prefix
path << File.basename(params[:key])
path = path.join("/")
imgix = Shrine.storages[:cache].client
url = imgix.path(path).to_url(w: 125, h: 125, dpr: 2, fit: "crop")

For my tests I want to use shrine-memory, but the above URL generation code relies on the Shrine.storages[:cache].storage method which isn't available in shrine-memory.

Is there a workaround for this using this gem? I don't need an actual working URL obviously, but ideally shrine-memory would be able to mimic's shrine-imgix interface.
