Errors NotRegistered flask-mongoengine Tutorial

Question

I started this Turial, Here

And get this error

**mongoengine.errors.NotRegistered:** `Comment` has not been registered in the document registry. Importing the document class automatically registers it, has it been imported?

any idea. Thank you So much.

Just place the Comment Model above the Post Model, since the Comment Model is being referenced in the Post Model

First register all your models some where like __init__.py file in your models package.

Then you can use get_document('Comment') function (which is imported from mongoengine.base.common) instead of importing your models in each other scripts to avoid circular imports and exceptions like mongoengine.errors.NotRegistered

could you provide an example using multiple files? – Sibelius Seraphini Mar 03 '16 at 16:25
I'm also facing the same issue, @Hamid please provide an example with circular import. – Rohit Khatri Nov 24 '16 at 13:07
