Question about find with key

[dustinsmith1024]

Is there a better way to find something by a name/id? This below works, but seems like the named parameter way should work too.

def find(email) do
    # Works fine, but I want to use the key
    # Diplomat.Query.new("select * from `User` where email_address = @email", %{email: email} )

    "select * from User where __key__ = KEY(User, \"#{email}\")"
    |> Diplomat.Query.new
    |> Diplomat.Query.execute
    |> hd
  end

When I use the names params:

 def find2(email) do
    Diplomat.Query.new("select * from User where __key__ = KEY(User, @email)", %{email: email})
    |> Diplomat.Query.execute
  end

I get:

iex(1)> u = User.find2("dds1024@gmail.com")
{:error,
 %Diplomat.Proto.Status{
   code: 3,
   details: [],
   message: "Encountered \"@email\" at line 1, column 46.\nWas expecting one of:\n    <INTEGER> ...\n    <SINGLE_QUOTE_STRING> ...\n    <DOUBLE_QUOTE_STRING> ...\n    "
 }}
iex(2)>

Semi-new to Google Data Store so I could be missing something simple.

Thanks!
