Der Phoenix Router bietet ausdrucksstarkes Routing zum Abgleichen von HTTP-Requests mit Controller-Aktionen und LiveViews ueber Pipelines.
Routen pruefen (Inspecting Routes)
# Alle definierten Routen und Pfad-Helfer auflisten
mix phx.routes
Ressourcen-Routing (Resource Routing)
# Generiert alle 7 standardmaessigen RESTful-Aktionen
resources "/users", UserController
# Generierte Aktionen einschraenken
resources "/posts", PostController, only: [:index, :show]
resources "/comments", CommentController, except: [:delete]
Generiertes RESTful-Routing-Mapping
| 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) |
Verschachtelte Ressourcen (Nested Resources)
resources "/users", UserController do
resources "/posts", PostController
end
Generiert verschachtelte Helfer:
# Routes.user_post_path(conn, :index, user_id)
# Routes.user_post_path(conn, :show, user_id, post_id)
