Adding new function to model module: Undefined function: Expected MyModule to define such a function or for it to be imported, but none are available

I noticed that validate_email takes changeset as a param, and yet this is never passed in. I guess this must be some auto-pass-in feature?

I tried the same thing with confirm_emails_match, and it now compiles, but MANY new warnings have cropped up caused by this. Baby steps.

defp confirm_emails_match(changeset, _attrs) do
    changeset
    IO.puts("TEST")
    # if attrs.email1 !== email2 do
    #   "todo"
    # end
  end

EDIT: I also see there is a validation_cofirmation which does this same thing. Still don’t understand why where the undefined error was coming from though.

Additional Info: I have another question similar to this. This was caused by passing in the incorrect params while inside of the pipes. I guess that’s similar to what is happening here?
