使用默认值初始化react-hook-form

Question

根据FAQ section in react-hook-form official website，应使用defaultValues用预先填充的数据初始化表单。但是，我调用API来获取初始数据，并且由于异步调用而导致初始化失败。

是否有更好或正确的初始化方法？

class ItemDetailView(DetailView):
    model = Item
    template_name = "product.html"

    def get_context_data(self, **kwargs):
        context = super().get_context_data(**kwargs)
        related_items = Item.objects.filter(category=self.object.category).order_by('category')
        context['related_items'] = related_items
        print(related_items)
        return context
