Hello, everybody,
I have a little problem I don't understand. Maybe you can help me.
I am writing a plugin that uses the "octoprint.filemanager.extension_tree" hook. The passed method uses _settings from octoprint.plugin.SettingsPlugin mixin. This worked fine until now, but when I add a init to my plugin class, the hook is called before _settings is available. Does anyone know why this happens and if I can work around this behaviour?
Maybe move your self._settings call into either on_startup or on_after_startup callbacks? If you could provide context of the code it might be more helpful.
Show us the code. How you call your init and then super-it is important. For example, here's a mistake I recently did...
class FileInfoScreen(Screen):
def __init__(self, **kwargs):
super(FileInfoScreen, self).__init__()
...
It's subtle but it needs to be this instead on the third line:
super(FileInfoScreen, self).__init__(**kwargs)
this is the code of my __ init__.py

Try instead:
def __init__(self, **kwargs):
super(Sla_plugin, self).__init__(**kwargs)
it works. Thanks. I'm gonna have to google something before I understand why it works, but it works.^^
Presumbably that "laundry list" of mixins is the **kwargs. (You made essentially the same mistake that I wrote about earlier.) Since you didn't init with at least the SettingsPlugin mixin then you wouldn't get access to settings.
