flask-react-docker-app's Issues

miss dockerfile for client

hi author,
I can not find the dockerfile for client folder.

TypeError: 'str' object is not callable

How to reproduce

# Start 
$ docker-compose up

# Run database migration
$ docker-compose exec api python manage.py db upgrade

# Run database seed
$ docker-compose exec api python manage.py seed_db

Go to:

http://localhost:8080/login

inspect the page and try login

If you look at request those errors are shown:

TypeError
