+ # Matches a url pattern to one or more routes.
+ #
+ # You should not use the `match` method in your router
+ # without specifying an HTTP method.
+ #
+ # If you want to expose your action to both GET and POST, use:
#
# # sets :controller, :action and :id in params
- # match ':controller/:action/:id'
+ # match ':controller/:action/:id', via: [:get, :post]
+ #
+ # Note that +:controller+, +:action+ and +:id+ are interpreted as url

+ #
+ # If you want to expose your action to GET, use `get` in the router:
+ #
+ # Instead of:
+ #
+ # match ":controller/:action/:id"
+ #
+ # Do:
+ #
+ # get ":controller/:action/:id"
#
# Two of these symbols are special, +:controller+ maps to the controller
# and +:action+ to the controller's action. A pattern can also map
# wildcard segments (globs) to params:
#
- # match 'songs/*category/:title', to: 'songs#show'
+ # get 'songs/*category/:title', to: 'songs#show'
#
# # 'songs/rock/classic/stairway-to-heaven' sets
# # params[:category] = 'rock/classic'
# # params[:title] = 'stairway-to-heaven'
#
+ # To match a wildcard parameter, it must have a name assigned to it.
+ # Without a variable name to attach the glob parameter to, the route
+ # can't be parsed.
+ #
# When a pattern points to an internal route, the route's +:action+ and
# +:controller+ should be set in options or hash shorthand. Examples:
#
- # match 'photos/:id' => 'photos#show'
- # match 'photos/:id', to: 'photos#show'
- # match 'photos/:id', controller: 'photos', action: 'show'
+ # match 'photos/:id' => 'photos#show', via: :get
+ # match 'photos/:id', to: 'photos#show', via: :get
+ # match 'photos/:id', controller: 'photos', action: 'show', via: :get
#
# A pattern can also point to a +Rack+ endpoint i.e. anything that
# responds to +call+:
#
- # match 'photos/:id', to: lambda {|hash| [200, {}, ["Coming soon"]] }
- # match 'photos/:id', to: PhotoRackApp
+ # match 'photos/:id', to: lambda {|hash| [200, {}, ["Coming soon"]] }, via: :get
