[DDE GUIDE ISSUE] Quick Edit functionality broken

[flaneuse]

1. Trying to edit any property in a registered dataset using the Quick Edit button on https://discovery.biothings.io/dashboard/ raises an error:

VM154:1 POST https://discovery.biothings.io/api/dataset 400 (missing name)

2. Longer term, it'd be good to have an interface to ADD information as well, rather than just edit properties that have already been filled out. With the Quick Edit button, I don't have access to fields which exist in the schema but aren't populated yet.
