[Bug] Unable to delete printer profiles via the trashcan icon.

[ayourk]

What were you doing?

Awhile back I added a printer I intended on purchasing. I never really did purchase this printer, so I wanted to delete that printer profile from OctoPrint. OctoPrint does not register (as far as I can tell) that the printer profile is deleted.

To recreate: Create a printer profile. Try to delete that profile. Deletion fails to register.

What did you expect to happen?

I expected the list of printer profiles to refresh without the printer profile I chose to delete.

What happened instead?

OctoPrint appeared to process something, then nothing in the list changed.

I have read the FAQ.

If it is the printer profile with the identifier "_default" you are trying to delete, that is not a bug but a misguided feature that I'll have to change.

Sadly your log does not appear to contain an actual deletion attempt (or I'm just blind right now) so I can't verify that right now - could you please elaborate?

Here is a picture of my Printer Profiles: http://i.imgur.com/aK4VxMp.png

I'm trying to delete the MakerGear M2 from the list. The interface appears to go through the motions of attempting to delete the printer profile, but the listing never disappears.

Sadly that screenshot doesn't help to determine if the profile in question has the _default identifier mentioned above. Could you please check what it says when you click on that MakerGear M2 profile's little pencil icon to edit it in the Identifier field?

If it says _default like in the above screenshot, it's as I thought and you are trying to delete what you defined as the default profile, and that currently can't be deleted. Has to be changed, was a stupid design decision when I introduced printer profiles.

[ayourk]

I can confirm it says "_default" in the Identifier field. How do I change that?

[ayourk]

I would have thought that the "STAR" symbol followed the default printer profile.

[foosel]

You currently can't change that. Identifiers are not modifiable. As I said, I made a wrong design decision here. The "star" does follow the default printer profile, the problem rather is that the profile with the identifier "_default" (both are NOT necessarily the same) is stored differently than the others and currently doesn't support deletion. It's also not something I can easily fix because that would cause problems in other places. So that might take a while to allow, sorry.

[ayourk]

I think I fixed it on my end by manually editing config.yaml while octoprint was shut down.

Problem appears to remain with deleting the "_default" printer.
