Phoenix Router offre un routing espressivo per associare richieste HTTP ad azioni di controller e LiveView tramite pipeline.
Ispezione delle route (Inspecting Routes)
# Stampare tutte le route definite
mix phx.routes
Routing delle risorse (Resource Routing)
# Genera tutte le 7 azioni RESTful standard
resources "/users", UserController
# Limitare le azioni generate
resources "/posts", PostController, only: [:index, :show]
resources "/comments", CommentController, except: [:delete]
Mappatura delle route RESTful generate
| HTTP Verb | Path | Action | Helper Function |
|---|---|---|---|
GET |
/users |
:index |
Routes.user_path(conn, :index) |
GET |
/users/new |
:new |
Routes.user_path(conn, :new) |
POST |
/users |
:create |
Routes.user_path(conn, :create) |
GET |
/users/:id |
:show |
Routes.user_path(conn, :show, id) |
GET |
/users/:id/edit |
:edit |
Routes.user_path(conn, :edit, id) |
PUT / PATCH |
/users/:id |
:update |
Routes.user_path(conn, :update, id) |
DELETE |
/users/:id |
:delete |
Routes.user_path(conn, :delete, id) |
Risorse nidificate (Nested Resources)
resources "/users", UserController do
resources "/posts", PostController
end
Genera helper nidificati:
# Routes.user_post_path(conn, :index, user_id)
# Routes.user_post_path(conn, :show, user_id, post_id)
Scope e pipeline (Scopes & Pipelines)

end
pipeline :api do

end
scope "/api", MyAppWeb.Api, as: :api do
