Ashes

A code generation tool for the Phoenix web framework.

defp deps do
  [{:ashes, ">= 0.0.3"}]
end

Controllers

Generates a controller with a given name, will also generate a view and create a folder for you to put related .eex templates in. Don't forget to add the controller in routes.ex

$ mix ashes.generate controller <controllername>

# web/router.ex
defmodule MyApp.Router do
  ...
  scope "/", MyApp do
    resources "/my", MyController
  end
end

Will give you the following functions by default:

• index
• edit
• new
• show
• create
• update
• delete

Options

• --skip-form - removes the edit and new functions from the controller (likely used for APIs)
• --skip-view - doesn't create a view module
• --skip-template- doesn't create a folder for templates

Channels

$ mix ashes.generate channel <channelname> [events]

# routes.ex
defmodule MyApp.Router do
  ...
  socket "/ws", MyApp do
    channel "my:*", MyChannel
  end
end

Will give you the following functions by default:

• join(_topic, message, socket)
• leave(_reason, socket)

If you provide events in the generate command, they will be added to the channel as

def handle_in("eventname", message, socket) do
  {:ok, socket}
end
