tortoise.exceptions.ConfigurationError: Unknown connection "default" for app "diff_models" about aerich

[codefather-labs]

My model metaclass example:

class Meta:
   table = 'TelegramApplication'
   default_connection = Database.telegram.name

[codefather-labs]

class Database(Enum):
    telegram = "postgres://{}:{}@{}:{}/{}".format(
        os.environ.get("DB_USER"),
        os.environ.get("DB_PASS"),
        os.environ.get("DB_HOST"),
        os.environ.get("DB_PORT"),
        os.environ.get("DB_NAME")
    )

OK, I fixed in 881f70f, you can install from github and give it a try.

[long2ice]

Just run pip install -e git+https://github.com/long2ice/aerich.git@dev#egg=aerich

[codefather-labs]

still got tortoise.exceptions.ConfigurationError: Unknown connection "default" for app "diff_models"

[codefather-labs]

it can connect to connection which not named 'default'? cuz i don't have 'default' connection

[long2ice]

You must specify --app=telegram

[codefather-labs]

finally dev branch works for me

[codefather-labs]

RUN mkdir vendor && cd vendor && git clone -b dev https://github.com/long2ice/aerich.git && \
    cd aerich && python3.8 setup.py install
RUN rm -rf vendor

RUN aerich --version

[long2ice]

OK, nice to hear that.
