Keep modal dialog open during form validation

[NetonD]

A solution I don’t like is to use instead of this:

Considering that you are dealing manually with the opening/close behavior of the modal, this can be the only solution to communicates your liveview handle_* with your front-end without re-rendering your template.

Client side the modal popups very fast while the server is still preparing (and transmitting) the form data. So the user is looking at an empty form

Maybe this can be useful, even for other possible problems like load bigger amount of data:

LiveView: how to create a loading state during form submission?

You need to decouple a little bit… first set loading status, then run the query. def handle_event("search", %{"q" => q}, socket) do send(self, {:run_search, q}) {:noreply, assign(socket, :set_loading, true)} end def handle_info({:run_search, q}, socket) do # do the actual work socket |> assign(:set_loading, false) |> assign(:result, ...) {:noreply, socket} end
