I am new to Phoenix_Live. I am going through Phoenix_Live project and need to handle live action in my code. Is handle_params the best place to handle the action? For example, I have :new action and have to change one of the assigns:
def handle_params(_, _url, socket) when socket.assigns.live_action == :new do
socket = assign(socket, selected_server: nil)
{:noreply, socket}
end
Where Next?

Assuming you want to access them on navigation via a patch link (
<.link patch={~p"/foo/new"}>new</.link>) or apush_patchthen yes,handle_params/3is the place to do this as it is called whenever there is a patch event. From your example it looks like that is what you want. Otherwise,@live_actionis available anywhere your assigns are. For example you could conditionally render a piece of your template in yourrender/1callback based on the@live_action.Just for completeness since you say you’re new, you can also write your code like this:
…which some people prefer, although I personally write it like you do so completely up to you
