Allow Custom Attribute Name for created_at

[mmaa]

By default, Phoenix uses inserted_at for the column name in timestamps(). This allows the customization of the created_at attribute name to align with Phoenix defaults.

You should be able to define a test for this purpose. use the token extension in a resource inside that test. Then you can assert on which attributes it has using Ash.Resource.Info.attributes(TokenResource).

test "uses created_at" do
  defmodule Token do
    use Ash.Resource, extensions: [....]
  end

  assert Ash.Resource.Info.attribute(Token, :inserted_at)
end

Thanks, @zachdaniel. I've added a test which confirms that this change is actually not working as expected. Looks like I'm still missing something.

Using create_timestamp :inserted_at does give me the attribute :inserted_at, but I still end up with a :created_at:

> Ash.Resource.Info.attribute_names(Example.TokenWithCustomCreateTimestamp)
MapSet.new([:inserted_at, :extra_data, :purpose, :created_at, :jti, :expires_at, :subject, :updated_at])

Hm...that's pretty strange. Is the timestamps() constructor being used somewhere?

The only references to timestamps are in the install task and test.

Interesting. I'd have to investigate further but the only other place it could be coming from is the token extensions transformer. Could thing else be adding that created at?
