Configuration for using Ecto with Weber

[AxisOfEval]

The Ecto Readme explicitly mentions putting the Repo into the supervise tree like so...

def init([]) do
  tree = [ worker(Repo, []) ]
  supervise(tree, strategy: :one_for_all)
end

They also recommend that start_link/0 function should not be called manually.

However, I found no convenient place to get this done in Weber. Am I missing something?

Hello @AxisOfEval,

Weber has no supervisors, so you can create your own and put it to the your_project_name/lib directory, something like:

defmodule SimpleWeber.Sup do
  use Supervisor.Behaviour

  def start_link do
    :supervisor.start_link({ :local, __MODULE__ }, __MODULE__, [])
  end

  def init([]) do
    tree = [  worker(Repo, []) ]
    supervise(tree, strategy: :one_for_all)
  end
end

And put SimpleWeber.Sup.start_link after https://github.com/0xAX/weber/blob/master/templates/default/lib/app.ex#L11

[AxisOfEval]

Thanks a ton for this @0xAX :). I am going to try this today and revert...

Tried doing things like as you said, but ./start.sh bails out with the following message whenever I put in the Supervisor or the Repo's start_link in the last line of the start method in app.ex

Substituting the Supervisor's start_link/0 call with that of the Repo's gets the same result. However, if I type in Repo.start_link in the iex console it seems to work. Ditto for the supervisor, albeit with some missed messages. What am I doing wrong?

Also, is there a way getting a trace (or other details) of what mix ends up doing, and why exactly it bails?

[AxisOfEval]

I played around somewhat. Anywhere before Weber.run_weber seems to do the trick. If the line goes after that, then things compile fine but ./start.sh fails to launch.

What's error after strart.sh?

[0xAX]

Ah sorry, missed your previous message. Which elixir version are you using? Did you enable logging?

[AxisOfEval]

I am using stuff pulled from the master branch. And yes, logging is enabled in lib/config.ex file. But nothing appears in the log files as start.sh bails out with the errors before lager/exlager can start...

If I start the supervisor before Weber.run_weber, things work OK. But I don't know if this is right.

I know this is an old thread, so @AxisOfEval, is there anything we still need to address here?

[AxisOfEval]

I am not sure I remember exactly what's going on here to the minutiae, but I should be able to check code and revert over the weekend. Hope that's OK!

[rcdilorenzo]

Any update @AxisOfEval? I'm planning to close this issue if not.
