Cannot create subject

[cxrodgers]

I am on the dev branch, so v0.5. I'm having trouble creating a subject by clicking the "+" in the Terminal GUI under the green button.

If I complete the subject's "id" textbox, but none of the other optional fields, and click "OK" I get this:

[22-08-02T16:12:38] DEBUG    [gui.widgets.subject.New_Subject_Wizard] Clicked OK to create subject                                                                  subject.py:57

    return compile(source, filename, mode, flags,
  File "<unknown>", line 0

If I put text in all the optional fields in the bio, I get this

What the heck i'm also getting this, but am sure that this worked because there's a roundtrip test of getting and setting from the widget here: https://github.com/auto-pi-lot/autopilot/blob/04b5968ba02c8a1413a27eb6a138b6a186b130f1/tests/test_gui/test_widget_model.py#L41

In any case i'm going to make a more informative error message when validating (there already is one, but this happens before it: https://github.com/auto-pi-lot/autopilot/blob/04b5968ba02c8a1413a27eb6a138b6a186b130f1/autopilot/gui/widgets/model.py#L234-L243

We need a test for the test! :laughing:

OK got it:

https://github.com/auto-pi-lot/autopilot/commit/0a2f081369b794920e62c1afee9e8cbf2e681dd6

see the diff there for specifics, but in short:

• Models can be recursive (ie. have other models as fields), and those submodels can be optional
• When getting values from optional models, the test for whether they were enabled was backwards (oops) so it was trying to get values from models even when they were empty/inactive
• When fields are empty, the input widgets weren't correctly handling that - so ast.literal_eval chokes on an empty string
• Some of the fields expect particular input - eg. the tags field is supposed to receive a dict, but at the moment that's not clearly specified in the visual appearance of the widget (there are tooltips but you have to hover over the field name, which isnt' obvious. intend to fix that), but there wasn't a specific error message telling you that.
• The tests only tested a complete biography, not an incomplete one, so this wasn't covered - added a separate test just to make sure that happens, though more tests for the individual input widgets are needed, but i have to do this defense rn lol.

lmk if that doesn't work.

edit: i am pretty happy with the design of that model widget and the inputs, it was pretty easy and very clear how to make that fix. sigh if only I had known how to write decent code when I started autopilot lol. Oh well! fixing it up piece by piece.

Works great, thanks!
