backref versus back_populates about v6_api HOT 3 CLOSED

Sorry to comment on an old, closed issue, but this shows up on the first page of google results when you search "backref vs back_populates".

there is a cyclic dependency between Document and DocumentVersion

SQLAlchemy's documentation shows using strings for the table references in relationships for this reason. You would always end up with circular imports if you had to import related classes. I personally consider backref detrimental to code quality, because it hides important information about what data the model contains.

I tried to change it, but there is a cyclic dependency between Document and DocumentVersion, so that I would have to add the relationship on Document after both classes have been defined. Which does not make it more explicit.

Not a big deal. Thanks for trying it out!
