Save profile image

[SimonLab]

Google and Github Oauth2 allow us to get basic information about the user.
We are currently only saving in our Postgres person database the email of the user:

auth-mvp/lib/auth_mvp/people/person.ex

Lines 8 to 14 in 3579966

	schema "people" do
	field :email, :string
	field :verified, :boolean, default: false
	has_many :sessions, AuthMvp.People.Session
	timestamps()
	end

We want now to be able to save the profile image of the user.
With Google the image url is already returned via ElixirAuthGoogle package under the picture value:

auth-mvp/lib/auth_mvp_web/controllers/google_auth_controller.ex

Line 9 in 3579966

{:ok, profile} = ElixirAuthGoogle.get_user_profile(token.access_token)

With Github the value to get will be saved under avatar_url

• Update the schema to add an avatar string field
• Add a new migration to create the avatar field in the database
• Update the person changeset to cast the avatar value:

def changeset(person, attrs) do
    person
    |> cast(attrs, [:email, :verified])
    |> validate_required([:email, :verified])
  end
