Helpers for selectable data_table/1 usage in LiveViews.

Use with Corex.DataTable: set selectable, selected, on_select, on_select_all, and row_id on the component (see the Selectable pattern in data_table/1 docs). In the LiveView, call assign_for_selection/3 in mount/3, then handle_select/3 and handle_select_all/3 from the matching handle_event/3 callbacks.

Example

def mount(_params, _session, socket) do
  socket =
    socket
    |> assign(:users, fetch_users())
    |> Corex.DataTable.Selection.assign_for_selection(:users, table_id: "users-table", row_id: &"user-#{&1.id}")

  {:ok, socket}
end

def handle_event("select", params, socket) do
  {:noreply, Corex.DataTable.Selection.handle_select(socket, params, :users)}
end

def handle_event("select_all", params, socket) do
  {:noreply, Corex.DataTable.Selection.handle_select_all(socket, params, :users)}
end

def render(assigns) do
  ~H"""
  <.data_table
    id="users-table"
    rows={@users}
    row_id={&"user-#{&1.id}"}
    selectable={true}
    selected={@selected}
    on_select="select"
    on_select_all="select_all"
  >
    <:col :let={user} label="ID">{user.id}</:col>
    <:col :let={user} label="Name">{user.name}</:col>
  </.data_table>
