Question

我正在尝试保存一个字段“公司”，它是一个自动完成字段。我正在使用ajax jquery，但是在尝试保存表单时出现错误：“选择一个有效的选择。该选择不是可用的选择之一。” 。只有输入公司ID（即1、2）而不是名称“ Jack in the Box”，我才能保存它。知道为什么会这样吗？

更新：在我的views.py-> QuestionCreate Class-> Post方法中，“ form.is_valid（）”失败了。我认为我的错误出在Post方法的某处，而我没有正确传递公司名称？请帮助！

django，python，jquery自动完成-选择一个有效的选择。该选择不是可用的选择之一
