Installation

Add ex_django to your mix.exs dependencies other dependencies are optional depending on what features you want to use.

defp deps do
[ {:exdjango, "~> 0.4.0"} ]
end

Django sessions

Add secret_key to config.exs and add either Cookie or Redis to endpoint.ex Plug config

# config.exs
config :exdjango, :config,
  secret_key: "django-secret-key"

# endpoint.ex
plug Plug.Session,
  store: ExDjango.Session.Cookie,
  key: "sessionid"

or

# config.exs
config :exdjango, :config,
  secret_key: "django-secret-key"
  redis_pool: MyApp.RedixPool

# endpoint.ex
plug Plug.Session,
  store: ExDjango.Session.Redis,
  key: "sessionid"

To use Redis session you need a redis connection pool see https://github.com/whatyouhide/redix for more information.

Set user / get user_id ("_auth_user_id" from django session)
