Openedx - 在创建课程时添加 Mongo 定义字段

Question

我正在使用 Ironwood 版本并尝试添加字段“程序”。调用函数 create_course，我发现以下错误。

File "/edx/app/edxapp/edx-platform/common/lib/xmodule/xmodule/modulestore/split_mongo/split.py", line 2007, in create_course
    search_targets, root_category, root_block_id, **kwargs
  File "/edx/app/edxapp/edx-platform/common/lib/xmodule/xmodule/modulestore/split_mongo/split.py", line 2022, in _create_courselike
    partitioned_fields = self.partition_fields_by_scope(root_category, fields)
  File "/edx/app/edxapp/edx-platform/common/lib/xmodule/xmodule/modulestore/__init__.py", line 1313, in partition_fields_by_scope
    field = getattr(cls, field_name)
AttributeError: type object 'CourseDescriptorWithMixins' has no attribute 'program'

谁能指导我缺少什么？

我遇到了同样的错误，当我将字段 'program' 添加到 common/lib/xmodule/xmodule/course_module.py 时，问题得到了解决。

class CourseFields(object):
...
    program = String(
        display_name=_("Program"),
        help=_("Specify the program of course."),
        default=None,
        scope=Scope.settings
    )
...
