[Merge] lp:~jtv/maas/node-nodegroup-not-null into lp:maas
Jeroen T. Vermeulen has proposed merging lp:~jtv/maas/node-nodegroup-not-null into lp:maas.
Requested reviews:
Launchpad code reviewers (launchpad-reviewers)
For more details, see:
https://code.launchpad.net/~jtv/maas/node-nodegroup-not-null/+merge/117395
Changes in diff order:
* Looks like I'm hitting this five-year-old Django bug — https://code.djangoproject.com/ticket/11920 and checking node.nodegroup_id instead of node.nodegroup works around it. Raphaël confirms that he does it this way too.
* Migration file is a manually adapted copy of the previous one. When you make a column NOT NULL, South effectively gives you the options “abort” and “specify a default value now.” The option I want is “resolve this in code,” which is conspicuously missing. A shame because I already fixed it in the code. Specifying a hard-coded id for the master nodegroup is a bit icky.
* Fields are required by default, so the model definition just became a little bit prettier.
* A test that was ready to become obsolete at this stage (for a type of failure that can no longer happen) has become obsolete and started breaking, so I deleted it.
