The liveview does not re-render after a phx-submit triggered "save" event. However,
it works as expected during a "dec" event.
Could it have to do with the functions being called from TodoLists.Catalog?
I have used IO.inspect to verify that socket.assigns changes before and after assign().
defmodule TodoLists.TodoListLive do
use TodoLists, :live_view
alias TodoLists.Catalog
on_mount {TodoLists.UserAuth, :current_user}
def mount(_params, _session, socket) do
user = socket.assigns[:current_user]
todo_lists = Catalog.list_lists(user)
{:ok,
socket
|> assign(:lists, todo_lists)
|> assign(:val, 0)
}
end
def handle_event("dec", _, socket) do
{:noreply, assign(socket, val: socket.assigns.val - 1)}
end
def handle_event("save", %{"todo_list" => list_params}, socket) do
user = socket.assigns[:current_user]
case Catalog.create_list(user, list_params) do
{:ok, todo_list} ->
socket
|> IO.inspect(label: "BEFORE")
{:noreply,
assign(socket, :lists, [todo_list | socket.assigns.lists])
|> IO.inspect(label: "AFTER")}
{:error, %Ecto.Changeset{} = changeset} ->
{:noreply,
socket
|> assign(:changeset, changeset)}
end
{:noreply, socket}
end
def render(assigns) do
