Inactive optional plugin won't run

[derrickb]

This could be related to a similar issue I filed on pyblish-lite: pyblish/pyblish-lite#90

I have an optional Validator, the first in the list, that I want to be off by default as it could take a long time to complete for larger scenes.

I have these properties on the plugin:

optional = True
active = False

If I attempt to run it either by itself or with the other plugins disabled, it doesn't get applied:

However if I change "active" to "True", then it does work:

Thanks for the detailed report @derrickb.

This looks to be some problem with the defaulting of the visual toggle in the GUI. active is the value the toggle is manipulating, and optional is what enables the user to manipulate it. By the looks of it, the toggle isn't getting the initial value of active as it is being loaded into the GUI.

Having a look at this as soon as possible.

Which version are you on?

>>> import pyblish_qml
>>> print(pyblish_qml.__version__)
0.7.1

0.7.1

This has now been fixed in 0.8.1

For completeness and future self, the issue was that the Pyblish Iterator is using the active flag as a means of determining whether or not to process a plug-in, but QML did not update this variable. Since QML runs remotely, it proved tricky to try and modify this member and so instead I implemented a slimmed down version of the iterator specifically for QML.

For now, it's an ok solution, but it does defeat the initial purpose of a common iterator. Namely that if behaviour changes I'll now need to update both base and qml separately.

This should also re-enable the use of instance.data["publish"] = False for defaulting the toggled status of instances.
