Queries returning scalar values

[mathias...@gmail.com]

I'm new to Ashikawa and ArangoDB. It seems that the Ashikawa Query class does not seem to be able to cope with scalar values getting returned from a query.

Example: 

list_user_names = db.query("for p in people return p.username")

names = q.to_a

This will fail with a NoMethodError in the Cursor class ("undefined method 'has_key?' for String).

Looking at the source of Cursor, it seems that 'detect_document_class_for' always expects a hash.

Is this by design and how do I work around this.

Thanks

Mathias

Hi Mathias,

Welcome :)

Thanks for your report! This is a bug.

If you return `p` entirely, it will work. Then you can ask for the `username` on the returned object.

This is however only a workaround, I will fix this as soon as possible. I created the issue here:

Best Wishes,

Lucas

Great, thanks - I'll work around this issue until the fix is available.

You're welcome :) Trying to get the new version ready sometime this week – maybe next week.

Best Wishes,
