Created schema not recognised

[Lazarus404]

Hi,

So, I use the install task to create a schema, but when I try to access the database, I get

** (exit) {:aborted, {:no_exists, [UserStore.User, #PID<0.395.0>]}}
     stacktrace:
       mnesia.erl:310: :mnesia.abort/1
       lib/amnesia/table.ex:484: Amnesia.Table.read!/2
       (app) lib/app/connection_store.ex:6: App.UserStore.User.read!/1
       (app) lib/app/connection_store.ex:73: App.ConnectionStore.lookup/1
       test/app_test.exs:6

My Schema is created with:

deftable User, 
    [:pid,:username,:bytes,:datetime], 
    type: :set, 
    index: [:username] do
    @type t :: %User{pid: pid, 
                           username: String.t, 
                           bytes: non_neg_integer, 
                           datetime: {{non_neg_integer, non_neg_integer, non_neg_integer}, {non_neg_integer, non_neg_integer, non_neg_integer}}}

On install, the necessary folders do get created.

Did you create the database after creating the schema? What's your creation code?

[Lazarus404]

use Amnesia

defdatabase UserStore do
  @ver "0"

  deftable User, 
    [:pid,:username,:bytes,:datetime], 
    type: :set, 
    index: [:username] do
    @type t :: %User{pid: pid, 
                           username: String.t, 
                           bytes: non_neg_integer, 
                           datetime: {{non_neg_integer, non_neg_integer, non_neg_integer}, {non_neg_integer, non_neg_integer, non_neg_integer}}}
  end
end

defmodule Mix.Tasks.Install do
  use Mix.Task
  use UserStore

  def run(_) do
    Amnesia.Schema.create
    Amnesia.start
    XSignal.UserStore.create(disk: [node])
    XSignal.UserStore.wait
    Amnesia.stop
  end
end

I then run tun "mix install" followed by "iex -S mix" to get my app running

Hi Meh,

Do you have a working example project that I can look over to see what the cause might be? Examples (other than in the readme.md" are few and far between.

Thanks

Sadly no, all examples I have are private stuff I can't share.

Anyway, if what you have there is the code, please use create! instead of create, or check the return value because the database is probably raising errors on creation.
