Programming Phoenix LiveView: promo form requires "to_form" changes (p133)
The schemaless form defined in file “lib/pento_web/live/promo_live.html.heex” on page 133 of the book requires some transformation. The :let={f} syntax no longer works.
In my understanding the changeset needs to be transformed using “to_form()” function, and the the syntax for the input fields has to be adapted too.
in “lib/pento_web/live/promo_live.ex”:
def assign_changeset(%{assigns: %{recipient: recipient}} = socket) do
socket
|> assign(:form, to_form(Promo.change_recipient(recipient)))
end
And in “lib/pento_web/live/promo_live.html.heex”:
<.input field={@form[:first_name]} type="text" label="First Name" />
<.input field={@form[:email]} type="email"
label="Email" phx-debounce="blur" />
I’m not 100% there yet, but now the form shows.
