[Django]-Docker Compose and Django generator syntax error

First of all

Your Django version is not compatible with Python 3.7

So make these changes

In your Dockerfile

FROM python:3.6 

Restart docker using sudo service docker restart

then sudo docker-compose up --build

or
sudo docker-compose run web python manage.py migrate and sudo docker-compose up --build

It seems that you are trying to run sample from byob-profiles-rest-api.

• This example is pretty old and you have to down grade your versions:

Change your Django version to 1.11 to avoid error

ModuleNotFoundError: No module named ‘django.core.urlresolvers’

Change your Python version to 3.6

SyntaxError: Generator expression must be parenthesized

• You files should now look like this

Dockerfile

FROM python:3.6

ENV PYTHONBUFFERED 1
RUN mkdir /code
WORKDIR /code
COPY . /code/
RUN pip install -r requirements.txt

requirements.txt

appdirs==1.4.3
Django==1.11
djangorestframework==3.6.2
packaging==16.8
pyparsing==2.2.0
pytz==2017.2
six==1.10.0

• Delete the old image of byob-profiles-rest-api
• Recreate the image by running

docker-compose run web python src/profiles_project/manage.py migrate

You should see that there’s no more errors.
