CRM开发学员课程系统——我的课程提交作业

 
#student/urls.py
#提交作业
url(r'my_homework/(d+)$',views.my_homework,name='my_homework'),

提交作业的文件是使用myDropzone,程序要新建一个文件放作业，文件目录为这样的格式：base_dir/class_id/course_record_id/studyrecord_id，使用chunks()把作业文件写入创建的文件：

#student/views.py
def my_homework(request,studyscore_id):
    """我的作业"""
    studyscore_obj = models.StudyRecord.objects.get(id=studyscore_id)
    if request.method == "POST":
        #print("request.FILES:",request.FILES)
        if request.is_ajax():
            homework_path = "{base_dir}/{class_id}/{course_recored_id}/{studycords_id}".
                format(base_dir=settings.HOMEWORK_DATA,class_id=studyscore_obj.student.enrolled_class_id,
                       course_recored_id=studyscore_obj.course_record_id,studycords_id=studyscore_obj.id)
            if not os.path.isdir(homework_path):
                os.makedirs(homework_path,exist_ok=True)
            for k,file_obj in request.FILES.items():
                with open("%s/%s"%(homework_path,file_obj.name),"wb") as f:
                    for chunk in file_obj.chunks():
                        f.write(chunk)
            return HttpResponse(json.dumps({"status":0,"msg":"file upload success"}))
    return render(request,"student/my_homework.html",{"studyscore_obj":studyscore_obj})
