<form
          id="select-outcome"
          phx-change="update-outcome"
          phx-value-entry_id={entry.id}
          class="flex justify-between items-center pl-6"
        >
          <.input
            type="select"
            name="outcome_selector"
            value={nil}
            disabled={assigns.read_only}
            options={@treatment_options}
          />
        </form>

  def handle_event(
        "update-outcome",
        %{"entry_id" => entry_id, "outcome_selector" => treatment_id},
        socket
      ) do
    treatment = Cvs.Event.Treatment.get_by_id!(treatment_id, actor: socket.assigns.current_user)
    entry = Cvs.MatchingTable.Entry.get_by_id!(entry_id, actor: socket.assigns.current_user)

    Cvs.MatchingTable.Entry.assign_to_matching_table!(
      entry,
      %{
        treatment_id: treatment.id
      },
      actor: socket.assigns.current_user
    )

    {:noreply, socket}
  end

I get this form and handle_event which work fine but I just cant get my test to work and I dont understand what Im doing wrong.

      html =
        edit_live
        |> form("#select-outcome", %{outcome_selector: t1.id})
        |> render_change()

Gives me that it expects def handle_event("update-outcome", %{"entry_id" => entry_id, "outcome_selector" => treatment_id}, socket)and cant match it which makes sense.

But with


      html =
        edit_live
        |> form("#select-outcome", %{entry_id: first_entry.id, outcome_selector: t1.id})
        |> render_change()

It gives ** (ArgumentError) could not find non-disabled input, select or textarea with name "entry_id" within which also makes sense but now I dont know how to actually get it working?

In order to understand what you are trying to do it would help if you actually provide the whole test code.

Perhaps you are confusing atom keys with string keys?

%{outcome_selector: t1.id}

vs.

%{"outcome_selector" => t1.id}

Since the value is coming from the client, you will probably want string keys (avoids atom exhaustion attacks).
