这个科莫宁.布里普checkpw方法在我重置密码后返回false-Elixir

defp put_pass_digest(changeset) do   
    case changeset do
      %Ecto.Changeset{valid?: true, changes: %{password: raw_passwd}} = cs ->
        put_change(cs, :password_digest, hashpwsalt(raw_passwd))
      changeset ->
        changeset
    end
  end

这是更改密码的方法:

def change_password(conn, %{"user" => %{"code" => code, "password" => password, "repeated_password" => repeated_password}}) do
    token = Repo.one(fetch_valid_token_q(code, "password_reset"))
    changeset = User.change_password_changeset(token.user, %{password: password, repeated_password: repeated_password})
    if changeset.valid? do
      Repo.update(changeset)
      render(conn, "password_changed.html")
    else
      changeset = User.changeset(%User{}, %{})
      conn
      |> put_flash(:info, "Wrong, try again!")
      |> render("reset_password.html", code: code, changeset: changeset)
    end
  end

变更集定义为:

def change_password_changeset(%User{} = schema, params) do
    schema
    |> changeset(params)
    |> validate_required([:password, :repeated_password])
    |> validate_password()
    |> passwords_match?()
    |> put_pass_digest
  end

下面是登录时调用的方法。

def login_user(args, _resolution) do
    with {:ok, user}         <- fetch_user_and_verify_password(args.session_input),
         {:ok, jwt, _claims} <- Guardian.encode_and_sign(user, :access)
    do
      {:ok, %{user: user, token: jwt}}
    else
      {:error, :incorrect_login_credentials} ->
        Errors.auth_required
    end
  end

def fetch_user_and_verify_password(params) do
    user = Repo.get_by(User, email: String.downcase(params.email))

    if check_password(params.password, user) do
      {:ok, user}
    else
      {:error, :incorrect_login_credentials}
    end
  end
defp check_password(password, user), do: checkpw(password, user.password_digest)

我查过数据库了。更新后的密码摘要正确保存在数据库中。不知道是什么问题。
