Docker-compose can't find .env file - django

Question

I have 3 containers with postgresql, nginx and django. The last two have their own Dockerfile, I run whole system with docker-compose. I have multiple problems:
I can't run my custom nginx container, named nginx with build: ./nginx/. only image: nginx. Yes, I try docker-compose build as was suggested in thread.
Strange behavior with volumes, I mentioned theese one: - ./web:/code and nothing work, i commented it, but now Django said me:
/usr/local/lib/python3.5/site-packages/environ/environ.py:609: UserWarning: /code/translation_microservice/.env doesn't exist - if you're not configuring your environment separately, create one.
"environment separately, create one." % env_file)

My docker-compose file:
version: '3'
services:
site:
build: ./web
env_file: ./web/.env
# wanna do this
#volumes:
# - ./web:/code
command: python manage.py runserver 0.0.0.0:8000
proxy:

image: nginx
ports:

And finally my both Dockerfiles. Django Dockerfile:

ENV PYTHONUNBUFFERED 1
RUN mkdir /code

ADD ./requirements.txt /code/
RUN pip install --no-cache-dir -r requirements.txt
ADD . /code/
EXPOSE 8000

Nginx Dockerfile:
FROM nginx:latest
COPY ./nginx.conf /etc/nginx/nginx.conf
