</html>我正在做一个项目学习，我想要一个带有课程的下拉列表，并把它的id传递给考试table.course id是一个外键，我想把这个课程id传递给table.By中的课程列，这段代码是错误的，不能分配“1”："Exam.course“必须是一个”Exam.course“实例。

首先，create()方法不需要调用save()方法，您可以在Exam模型中直接分配课程id，因此视图应该是：
def Examadd(request):
mycourses = Courses.objects.all()
context = {'mycourses': mycourses}
if request.method == 'POST':
newexam = request.POST.get('examname')
course = request.POST.get('courses')
examtime = request.POST.get('time')
new = Exam.objects.create(exam_name=newexam,course__id=course,exam_time=examtime)
messages.success(request, "Course created successfully")
return redirect('Courselist')
return render(request,'addexam.html',context)页面原文内容由Stack Overflow提供。腾讯云小微IT领域专用引擎提供翻译支持
