Resources have no "name"s

[danfowler]

When generating Data Package, using:

# https://github.com/frictionlessdata/datapackage-py

from datapackage import pull_datapackage
from sqlalchemy import create_engine

engine = create_engine('mysql://root@localhost/enliten')

# Push
pull_datapackage(
    descriptor='enliten-datapackage/datapackage.json',
    name="enliten-datapackage",
    backend='sql',
    engine=engine)

None of the resources have names (now required). This results in the foreignKeys generated in one of the resources in the datapackage.json referring to null resources.

"schema": {
  "foreignKeys": [
    {
      "fields": "user_id",
      "reference": {
        "resource": null,
        "fields": "id"
      }
    },
    {
      "fields": "group_id",
      "reference": {
        "resource": null,
        "fields": "id"
      }
    }
  ]
