Python MongoModuleStore.create_course方法代码示例

# 需要导入模块: from xmodule.modulestore.mongo import MongoModuleStore [as 别名]
# 或者: from xmodule.modulestore.mongo.MongoModuleStore import create_course [as 别名]
class SplitWMongoCourseBoostrapper(unittest.TestCase):
    """
    Helper for tests which need to construct split mongo & old mongo based courses to get interesting internal structure.
    Override _create_course and after invoking the super() _create_course, have it call _create_item for
    each xblock you want in the course.
    This class ensures the db gets created, opened, and cleaned up in addition to creating the course

    Defines the following attrs on self:
    * userid: a random non-registered mock user id
    * split_mongo: a pointer to the split mongo instance
    * old_mongo: a pointer to the old_mongo instance
    * draft_mongo: a pointer to the old draft instance
    * split_course_key (CourseLocator): of the new course
    * old_course_key: the SlashSpecifiedCourseKey for the course
