how to use form_with

[fugee ohu]

Trying to build a rails 5.2 form using form_with I get this error: ActionView::Template::Error (wrong number of arguments (given 1, expected 0)):

<%= form_with @item, url: new_item_path, method: 'get' do |f| %>

     <div class="field">
        <%= f.select :item, :item_type_id, ItemType.all, :id, :name %>
     </div>

    <div class="actions">
        <%= f.submit "New item" %>
    </div>

<% end %>

Have you read the Rails API docs and Rails Guides for usage of form_with?

Which item in the code you shared is being given five arguments? Look there. (It's not the form_for.)
