Import course in Admin Backend

I am closing this issue as not a bug. If you have issue you can reopen it.

to get orphans problems you will have to calculate them by traversing upward from problems to course. To have an ideathis view orphan_handler will return you the list of orphans for a course_key_string or you can do this directly:

I can understand that thanks for the explanation.
Just a small question how can I get orphan_problems_count. It that there with course object or it has to be calculated.
If that needs to be calculated please let me have a hint for the same so that I can resolve the issues I was facing from a quite long duration.

Thanks for the help again.

The thing is if there is a record in mongo like:

and you import a course which don't have this problem. So during referencing after importing a course this module will not have any parent so it will be in mongo but not be a part of course. This is the reason you are getting wrong number of problems (more then they need to be). So actual count of problems would be total_problems_count - orphan_problems_count.
To get a rough idea of how much orphans does your course have you can use a uri like this:

Please let me know if there is still any confusion.

Thanks for attention Zubair
Here is the actual scenario:-
Suppose there is a course in mongo db whose course problem is below:-

"_id" : {
"tag" : "i4x",
"org" : "org_name",
"course" : "course_id",
"category" : "problem",
"name" : "202680ce24244ebdb345167ff599b9f0",
"revision" : null
},

now what I do is replace the course with a new course but I remove this problem from the course that will be imported.
This is what will happen :-
All the records in Mongodb that are not in the course that is being imported will be replaced and the problem that was in course earlier but now it is not there that remains as it in Mongodb.
Now if I count number of problems in Mongodb using
"org" : "org_name",
"course" : "course_id",
"category" : "problem",
This will show me a wrong count. As the problem that was in mongoDB has not been replaced.

Do let me know if you need more explanation.
