Doesn't work with most recent version of Phoenix? about arc

[stavro]

Can I see your mix.exs file, specifically where you added your
dependencies, as well as your attachment.ex file?

Hello, I'm trying to use your app and I set up everything like in the
README but it keeps giving this error:

== Compilation error on file web/uploaders/attachment.ex ==

I've got the 'use Arc.Definition' macro and have the mix.exs file setup
correctly as well as the config.exs (I think)

Configuration for the OTP application.

Type mix help compile.app for more information.

def application do
[mod: {MyApp, []},
applications: [:phoenix, :phoenix_html, :cowboy,
:phoenix_ecto, :mariaex, :comeonin,
:tzdata, :ex_aws, :httpoison]]
end

Specifies which paths to compile per environment.

defp elixirc_paths(:test), do: ["lib", "web", "test/support"]
defp elixirc_paths(_), do: ["lib", "web"]

Specifies your project dependencies.

Type mix help deps for examples and options.

defp deps do
[{:phoenix, "> 1.0.3"},
{:phoenix_ecto, "> 1.1"},
{:mariaex, ">= 0.0.0"},
{:phoenix_html, "> 2.1"},
{:phoenix_live_reload, "> 1.0", only: :dev},
{:cowboy, "> 1.0"},
{:comeonin, "> 1.2"},
{:timex, "> 1.0.0-rc3"},
{:arc, "> 0.2.2"},
{:arc_ecto, ">= 0.0.0"},
{:ex_aws, "> 0.4.10"},
{:httpoison, "> 0.7"}]
end

defmodule MyApp.Attachment do
use Arc.Definition

Include ecto support (requires package arc_ecto installed):

use Arc.Ecto.Definition

@versions [:original]
@acl :public_read

To add a thumbnail version:

@versions [:original, :thumb]

Whitelist file extensions:

def validate({file, _}) do

~w(.jpg .jpeg .gif .png) |> Enum.member?(Path.extname(file.file_name))

end

Define a thumbnail transformation:

def transform(:thumb, _) do

{:convert, "-strip -thumbnail 250x250^ -gravity center -extent 250x250 -format png"}

end

Override the persisted filenames:

def filename(version, _) do

version

end

Override the storage directory:

def storage_dir(version, {file, scope}) do
"uploads/tickets/attachments/#{scope.id}"
end

Provide a default URL if there hasn't been a file uploaded

def default_url(version, scope) do

"/images/avatars/default_#{version}.png"

end

end

[stavro]

It feels like something might be wrong with the compilation... Can you try to rm -r _build/ and then re-run iex -S mix, and confirm that the arc library went through compilation?

[stavro]

and you're still getting the error when running iex -S mix?

[sashaafm]

It works now. Thanks! Was this my problem or arc's?

[sashaafm]

Sorry for using the issues section for support, but I think I've done everything correctly but my files do not upload to S3. I receive a {:ok, "filename.png"} as expected by the examples but it does not upload to my S3 bucket

UPDATE:

It works now, the code was fine. There's some kind of problem with some regions, at least with the Frankfurt region. I created another bucket in the US Standard region and it worked right away it seems.

[stavro]

If you want to use the Frankfurt region, you must add the following to your config:

config :arc,
  virtual_host: true

config :ex_aws,
  s3: [
    scheme: "https://",
    host: "s3.eu-central-1.amazonaws.com",
    region: "eu-central-1"
  ]

[stavro]

Please let me know if you find any more issues. Good luck!
