View Source Routex.Extension.Assigns (Phoenix Routes Extension Framework v0.3.0-alpha.4)

Extracts Routex.Attrs from the route and makes them available in components and controllers with the @ assigns operator (optionally under a namespace).

Options

  • namespace: when set creates a named collection of Routex.Attrs
  • attrs: when set defines keys of Routex.Attrs to make available

Configuration 

# file /lib/example_web/routex_backend.ex
defmodule ExampleWeb.RoutexBackend do
  use Routex.Backend,
  extensions: [
+   Routex.Extension.Assigns,
Routex.Extension.AttrGetters
],
+ assigns: %{namespace: :rtx, attrs: [:branch_helper, :locale, :contact, :name]}

Pseudo result 

# in (h)eex template
@rtx.branch_helper   ⇒  "eu_nl"
@rtx.locale         ⇒  "nl"
@rtx.contact        ⇒  "verkoop@example.nl"
@rtx.name           ⇒  "The Netherlands"
