Routes are specified on a per-component basis in the config/routes.rb file. Routes simply map from URL to params.
client "/todos", {view: 'todos'}
Routes take two arguments: a path and a params hash. When a new URL is loaded and the path is matched on a route, the params will be set to the params provided for that route. The specified params hash acts as a constraint. For example, an empty hash will match any url. Any params that are not matched will be placed in the query parameters.
When the params are changed, the URL will be set to the path for the route whose params hash matches.
Route paths can also contain bindings, which map into the params collection:
client "/todos/{{ index }}", view: 'todos'
In the case above, if any URL matches /todos/, (where is anything but a slash), it will be the active route. In this case, params._view would be set to 'todos', and params._index would be set to the incoming value in the path.
If params._view is 'todos' and params._index is present, the route will be matched.
Routes are matched from top to bottom in a routes file.
You can use * as you would in a ruby splat to match the rest of the url (not just a single section):
client "/blog/{{ *slug }}", component: 'main', controller: 'blog', action: 'show'
The above will match anything that starts with /blog/, the rest of the url will be placed in params._slug
For setting up HTTP endpoints via the HTTP Controllers you need to specify routes with the get, post, put, patch or delete keywords. Routes for HTTP endpoints require you to set the controller and action as params on the route.
get "/api/todos", controller: 'todos', action: 'index'
The above will call the index method on the TodosController. See HTTP Controllers for more details.
To create a RESTful resource you have to create the following routes
get "/api/todos", controller: 'todos', action: 'index'
post "/api/todos", controller: 'todos', action: 'create'
get "/api/todos/{{ id }}", controller: 'todos', action: 'show'
put "/api/todos/{{ id }}", controller: 'todos', action: 'update'
patch "/api/todos/{{ id }}", controller: 'todos', action: 'update'
delete "/api/todos/{{ id }}", controller: 'todos', action: 'destroy'
All additional params are passed down to the controller.
delete "/api/todos/{{ id }}", controller: 'todos', action: 'destroy', safe: true
The above will make id, controller, action and safe availabe to the controller via the params hash.
You can overwrite the actual HTTP method by providing setting "method" via the HTTP GET or POST parameters.
