Cannot persist a float number

Cannot persist a float number

Closed this issue a year ago · 3 comments

Describe the bug
I'm getting (ArgumentError) cannot load 0.9 as type #Ash.Type.Float.EctoType<[]> when trying to persist a float number to an SQLite database.

To Reproduce
Using the following definitions:

defmodule AshFloatDomain do
  use Ash.Domain

  resources do
    resource AshFloatError
  end

end

defmodule AshFloatError do
  use Ash.Resource,
    domain: AshFloatDomain,
    data_layer: AshSqlite.DataLayer

  actions do
    defaults [:read]

    create :create do
      accept [:temperature]
    end
  end

  attributes do
    uuid_primary_key :id
    attribute :temperature, :float, allow_nil?: true
  end

  sqlite do
    table "ash_float_error"
    repo Elani.Repo
  end
end

after generating and running the migrations, this code produces the error:

iex(25)> AshFloatError |> Ash.Changeset.for_create(:create, %{temperature: 0.9}) |> Ash.create!()
** (Ash.Error.Unknown) 
Bread Crumbs:
  > Error returned from: AshFloatError.create

Unknown Error

Expected behavior
I expect that I'm able to persist a float number.
