What do you think is the best way to handle errors on actions (not forms), like the delete Button. I see two ways:

  • Use Changeset and show the errors on the flash message (when using fullstack)
  • Returning an error on the corresponding method and showing it in the flash message
def delete(model) do
   if .... do
     ...
     :ok
   else
     {:error, :whatever}
   end
end

case delete(model) do
  ok ->
    ...
  {:error, :whatever} ->
    put_flash(socket, :error, "Whatever")
  error -> 
    raise "Case not handled"
end

Thanks :slight_smile:
