Compilation Error on repo.ex

Phoenix Forum Questions / Help

Hello, I am new to Phoenix Framework and I have been attempting to push an app that I have working locally to a remote Linux box from my local Mac. Some additional background, I have been following this tutorial for my deployment steps: https://www.digitalocean.com/community/tutorials/how-to-automate-elixir-phoenix-deployment-with-distillery-and-edeliver-on-ubuntu-16-04

Files are getting shipped over when I ‘mix edeliver build release’, but I get an error that says:

Compilation error in file lib/phxgas/repo.ex ==
** (ArgumentError) missing :adapter configuration in config :phxGas, PhxGas.Repo
lib/ecto/repo/supervisor.ex:70: Ecto.Repo.Supervisor.compile_config/2
lib/phxgas/repo.ex:2: (module)
(stdlib) erl_eval.erl:670: :erl_eval.do_apply/6

Here’s what my repo.ex looks like:

defmodule PhxGas.Repo do
use Ecto.Repo, otp_app: :phxGas

@doc “”"
Dynamically loads the repository url from the
DATABASE_URL environment variable.
“”"
def init(_, opts) do
{:ok, Keyword.put(opts, :url, System.get_env(“DATABASE_URL”))}
end
end

Does anybody have any troubleshooting suggestions for me? I have read a few posts from @OvermindDL1 that suggest I may need to add an adapter to my repo.ex. I’m just uncertain as to how to go about trying that if that’s indeed what I need to do.

Thanks for your time!

Actually you need your adapter added to the configuration files. What are your configuration files contents (removing any potentially secure information of course)?

Thanks so much for your willingness to help. Here are the contents of my configs.

BUILD_HOST=“domain”

BUILD_AT="/home/user/app_build"

PRODUCTION_HOSTS=“domain”

pre_erlang_get_and_update_deps() {
local _prod_secret_path="/home/user/config/prod.secret.exs"
if [ “$TARGET_MIX_ENV” = “prod” ]; then
__sync_remote "
ln -sfn ‘$_prod_secret_path’ ‘$BUILD_AT/config/prod.secret.exs’

fi

I added the following to prod.exs and config.exs

config :phxGas, PhxGas.Repo,
adapter: Ecto.Adapters.Postgres,
username: “username”,
password: “password”,
database: “dbname”,
pool_size: 15

I am no longer getting the adapter error, but I see

Failed to detect generated release at
user@domain:/home/user/app_build

Please set RELEASE_DIR in the config file to fix that,
or check that the APP variable is set correctly.

Should I set RELEASE_DIR to the same value as DELIVER_TO ("/home/user/app_release")

Thanks again for walking me through these!

Hooray! Adding the release_dir got me through that last error.

RELEASE BUILD OF PHXGAS WAS SUCCESSFUL!

Thanks a million!

Hah, sorry for the delay, I just got back! ^.^;

Awesome though! :smiley:

Oh, another question actually if you have a second.:grimacing: Do you happen to know where I change the release store location? I guess this more of an edeliver question, but now I’m getting

Copying phxGas.tar.gz to release store
scp: /home/user/phxGas/releases/*/phxGas.tar.gz: No such file or directory

I was thinking my release would be writing to /home/user/app_release

8

Yeah this bit is entirely an edeliver thing (I juse use distillery straight), I don’t use it so I’d recommend making a new thread about it. ^.^;

Ok, gotcha. Sounds like I should go that route as well. Thanks again for all your help!
