Custom page fields for pages.

Each Beacon.Content.Page have a default set of fields that fits most cases for building pages for your sites, but in some cases you need custom data to either help manage those page in Beacon Admin or to display such data.

For example, you can add a field to store each blog post illustration, or a field to include tags, and so on.

Each page field will be:

• stored in the page.extra map field
• displayed in Beacon LiveAdmin
• validated when the pages is saved or published

Example

defmodule MyApp.TagsField do
  use Phoenix.Component
  import Beacon.Web.CoreComponents
  import Ecto.Changeset

  @behaviour Beacon.Content.PageField

  @impl true
  def name, do: :tags

  @impl true
  def type, do: :string

  @impl true
  def render(assigns) do
    ~H"""
    <.input type="text" label="Tags" field={@field} />
    """
  end

  @impl true
  def changeset(data, attrs, _metadata) do
    data
    |> cast(attrs, [:tags])
    |> validate_required([:tags])
  end
end
