defmodule AshAdmin.Router do
@moduledoc """
Provides LiveView routing for AshAdmin.
"""
@doc """
Can be used to create a `:browser` pipeline easily if you don't have one.
By default it is called `:browser`, but you can rename it by supplying an argument,
for example:
```elixir
defmodule MyAppWeb.Router do
use Phoenix.Router
import AshAdmin.Router
admin_browser_pipeline :something
scope "/" do
pipe_through [:something]
ash_admin "/admin"
end
end
```
"""
defmacro admin_browser_pipeline(name \\ :browser) do
quote do
import Phoenix.LiveView.Router
pipeline unquote(name) do
plug(:accepts, ["html"])
plug(:fetch_session)
plug(:fetch_live_flash)
plug(:put_root_layout, {ThingyWeb.LayoutView, :root})
plug(:protect_from_forgery)
plug(:put_secure_browser_headers)
end
end
end
@doc """
Defines an AshAdmin route.
It expects the `path` the admin dashboard will be mounted at
and a set of options.
## Examples
defmodule MyAppWeb.Router do
use Phoenix.Router
scope "/" do
import AshAdmin.Router
# Make sure you are piping through the browser pipeline
# If you don't have one, see `admin_browser_pipeline/1`
pipe_through [:browser]
ash_admin "/admin"
end
end
