defmodule Thesis.Controller do
@moduledoc """
Provides a plug that preloads any Thesis content for a page.
Typically, you'll add this to your `web/web.ex` file, under the `controller`
function:
def controller do
quote do
use Phoenix.Controller
use Thesis.Controller
# ...
end
end
If you'd prefer to only use Thesis in certain controllers, remove it from
`web/web.ex` and add it to the specific controllers by doing this:
defmodule MyApp.MyController do
use Thesis.Controller
# ...
"""
defmacro __using__(_) do
quote do
plug Thesis.Controller.Plug
end
end
end
defmodule Thesis.Controller.Plug do
import Plug.Conn, only: [assign: 3]
import Thesis.Config
def init(_) do
end
def call(conn, _opts) do
current_page = store.page(conn.request_path)
page_contents = store.page_contents(current_page)
conn

end
