I have a weird issue that I cannot figure out:
I have a basic setup where on mount I retrieve items, and add them to the stream:
case Event.all_events() do
{:ok, events} ->
{:ok,
socket
|> stream_configure(:events, dom_id: &"event-#{&1.id}")
|> stream(:events, events)}
{:error, _} ->
{:ok, handle_forbidden_error(socket)}
end
I’m also subscribed to a PubSub, so when an event is updated, I insert/update it into stream:
def handle_info(%{topic: "event:updated:status", payload: %{data: data}}, socket) do
user = socket.assigns.current_user
case data.user_id == user.id or user.role == "admin" do
true ->
{:noreply,
socket
|> stream_insert(:events, data, at: 0)}
false ->
{:noreply, socket}
end
end
For some reason, when I insert the item, all items from the stream disappear, and only this one item is added. If the item already exists on the page, same thing: all items are removed, the item is updated (or a new one is inserted?).
Doesn’t matter if I use at: N or not.
