1. 只需在common/lib/xmodule/xmodule/course_module.py添加app
例如code
note_topics = Dict( display_name=_("Note Topic Mapping"), help=_("Enter note categories in the following format: \"CategoryName\": {\"id\": \"i4x-InstitutionName-CourseNumber-course-CourseRun-Note\"}. For example, one discussion category may be \"Lydian Mode\": {\"id\": \"i4x-UniversityX-MUS101-course-2014_T1-Note\"}."), scope=Scope.settings )
