django.db.utils.OperationalError: (2005, "Unknown MySQL server host 'db' (-2)")
I'm working windows 10. I also have the kiwi_db that is constantly restarted in docker

Unknown MySQL server host 'db' (-2)"
The error message itself is clear enough. Your DB server doesn't seem to be up and running.
I'm working windows 10. I also have the kiwi_db that is constantly restarted in docker
Kiwi TCMS and MySQL/MariaDB are Linux based containers so maybe your Windows host is not capable of running Linux containers in the first place. Refer to Docker's documentation/support on that matter.
This may be of help but fair warning that it's been written by a 3rd party not affiliated with the Kiwi TCMS team:

How can I fix Flask in local appengine env giving 404/500 error

I followed the whole tutorial, copying the latest files from github, and am trying to run it in the local env.
dev_appserver.py --port=8080 --enable_console=yes app.yaml
When I try to browse to http://localhost:8080
In the console, I get

HTTP ERROR 500
I've found some posts with similar symptoms, but not exact. And none of the solutions suggested fix the issue.
Tried:
- Specifying the port 8080 in the dev_appserver.
- Ensuring ASP.NET framework was installed.
- Turning on IIS.
- Ensuring SDK is latest version.
This is also just straight from Google's tutorial.
Anybody have any insight/ideas?

I was getting very same error in MS windows, so switched to Ubuntu but still I am getting this. And getting this error after I updated my Google app engine SDK to 1.8.2, previous version was working fine.
Any guess why this is happening ?
Thanks in advance.

Well, I was using the proxy then and GAE/Python Snippet checks for update before running the server and was unable to locate the update server using proxy. Thats why I was getting that error.
I started using network without proxy and things started working normally :).

KeyProperty object has no attribute get

I placed a _post_put_hook into one of my NDB model types so that that whenever an entity of that type were put, it would invalidate a memcache key. This key is made up with the urlsafe version of the settings key. However, when this code runs, it says this:

AttributeError: 'KeyProperty' object has no attribute 'get'
Here is the relevant model class:
class Team(ndb.Expando):
name = ndb.StringProperty()
show_team = ndb.BooleanProperty()
settings = ndb.KeyProperty()
#classmethod
def _post_put_hook(self, future):
memcache.delete('allteams-' + self.settings.get().websafe)
Ideas?

in this case self.settings is not the actual key but the Models property because this is a classmethod and not an instance method. you need to work on the future object.
here the docs: https://developers.google.com/appengine/docs/python/ndb/futureclass
in this case:
#classmethod
def _post_put_hook(self, future):
entitykey = future.get_result()
entity = entitykey.get()
memcache.delete('allteams-' + entity.settings.get().websafe)
not sure what websafe does for you. maybe you mean entity.settings.urlsafe() ?
