IDK, some weirdness in tornado? No idea, you might try StackOverflow or track down the original exception? This is the original traceback, you can help me? @coleifer

```
This is my code
```
from peewee import *
from datetime import datetime
from decouple import config

import uuid


DATABASE = PostgresqlDatabase(
    config('BOTHUB_POSTGRES_DB'),
    user=config('BOTHUB_POSTGRES_USER'),
    password=config('BOTHUB_POSTGRES_PASSWORD'),
    host=config('BOTHUB_POSTGRES'),
    port=config('BOTHUB_POSTGRES_PORT'), threadlocals=True)


class BaseModel(Model):
    class Meta:
        database = DATABASE

class Bot(BaseModel):
    uuid = UUIDField(primary_key=True, default=uuid.uuid4)
    bot = BlobField()
    created_at = DateTimeField(default=datetime.now)
    updated_at = DateTimeField()

    def save(self, *args, **kwargs):
        self.updated_at = datetime.now()
        return super(Bot, self).save(*args, **kwargs)

    class Meta:
        db_table = 'bots'


```

I don't know the reason for it, I saw a similar problem in issues (#334) and to "solved" it I did started my db with `threadlocals=True`, but it no solve my problem, you know to solve this?
