roda-action 
A plugin for Roda to resolve actions from roda-container
Installation
gem 'roda-action', '0.1.0'Usage
class MyApplication < Roda
plugin :json
plugin :action
end
class UsersController
attr_reader :repository
def initialize(repository = [])
@repository = repository
end
def index
repository
end
def show(user_id)
repository[user_id.to_i - 1]
end
end
MyApplication.register(:users_controller) do
UsersController.new([
{ name: 'Jack' },
{ name: 'Gill' }
])
end
MyApplication.route do |r|
r.on 'users' do
r.is do
r.get(&action(:users_controller, :index))
end
r.is :id do |id|
r.get(&action(:users_controller, :show).bind_arguments(id))
end
end
endIf you wish to have access to the usual Roda application instance methods in your registered controllers, it is recommended that you register the application and resolve it for use in your controllers:
NOTE: Be sure to use .instance as below, see: https://github.com/AMHOL/roda-container#thread-safety
class MyApplication < Roda
plugin :json
plugin :action
end
class UsersController
attr_reader :app, :repository
def initialize(app, repository = [])
@app, @repository = app, repository
end
def index
repository
end
def show(user_id)
repository[user_id.to_i - 1]
end
def create
id = repository.length.next
if (name = app.request.params['name'].to_s).length > 0
repository << { name: name }
app.response.redirect "/users/#{id}"
end
end
end
MyApplication.register(:users_repository, [
{ name: 'Jack' },
{ name: 'Gill' }
])
MyApplication.register(:users_controller) do
UsersController.new(
MyApplication.instance.resolve(:app),
MyApplication.resolve(:users_repository)
)
end
MyApplication.route do |r|
register(:app, self, call: false)
r.on 'users' do
r.is do
r.get(&action(:users_controller, :index))
r.post(&action(:users_controller, :create))
end
r.is :id do |id|
r.get(&action(:users_controller, :show).bind_arguments(id))
end
end
