Hi!
I want to create a user and also profile schema at the same time.

For example

defmodule MyApp.Accounts.User do
  use Ecto.Schema
  import Ecto.Changeset

  schema "users" do
    field :username, :string
    field :password, Comeonin.Ecto.Password
    field :email, :string

    has_one :profile, MyApp.Accounts.Profile
    timestamps()
  end
end

defmodule MyApp.Accounts.Profile do
  use Ecto.Schema
  import Ecto.Changeset

  schema "profiles" do
    field :phone_number, :string
    field :address, :string
    field :intro, :string

    belongs_to :user, MyApp.Accounts.User
    timestamps()
  end
end

then I got an input from user like this

attrs = %{username: "username",
          password: "secret", 
          email: "email@example.com", 
          phone_number: "2223334444", 
          address: "some address", 
          intro: "Hello world!"}

then in my accounts.ex file

def create_user(attrs) do                                                                                                                                     
     user_changeset = User.changeset(%User{}, attrs)                                                                                                                   
     profile_changeset = Profile.changeset(%Profile{}, attrs)
                                                                  
     user_changeset                                                                                                                                                    
     |> Ecto.Changeset.put_assoc(:profile, profile_changeset)                                                                                               
     |> Repo.insert()                                                                                                                                                   
end    

I think it works…
But is there any better (elixir) way?
