"ValueError: too many values to unpack" with SQLAlchemy 1.2.2

[command-tab]

When using SQLAlchemy 1.2.2 with Flask-WTF 0.14.2, using a QuerySelectField, Flask-WTF raises "ValueError: too many values to unpack" in wtforms/ext/sqlalchemy/fields.py line 189, in get_pk_from_identity. It appears that SQLAlchemy 1.2 and later returns a third member from that call, and the library only expects two. Here's separate project's PR about the issue, and whose fix may be worth considering:
wtforms/wtforms-sqlalchemy#10

I've put together a small Flask app demonstrating the bug here:

That's part of WTForms, not Flask-WTF.

@lepture what do you want to do here? WTForms isn't being updated, but I don't really want to pull this into Flask-WTF.

@davidism Oh, silly me! I should have seen that it was an issue directly in WTForms.

What do you mean when you said WTForms isn’t being updated? Is the project no longer maintained?

Thanks!

[davidism]

It's still stable and usable, but I don't have access to make new releases, only to merge stuff.

[command-tab]

Hmm. Should I open a similar issue or PR over in WTForms for someone to review and merge, then a project owner to release?

[davidism]

You can, I can review and merge it at some point when I have time.
