How to test

(Include any information that may be helpful to the reviewer(s). This might include links to sample pages to test or any local environmental setup that is unusual such as environment variable (never credentials), API version to point to, etc)

Terminal#1:

1. create python 3.7.12 virtualenv for fec-eregs: run pyenv virtualenv 3.7.12 venv-eregs-3712
2. pyenv activate venv-eregs-3712
3. checkout branch
4. open requirements.txt and change line 37 from:
   -e git+https://github.com/fecgov/regulations-parser.git@master#egg=regparser
   to:
   -e git+https://github.com/fecgov/[email protected]#egg=regparser
5. open requirements-parsing.txt and change line 73 from:
   -e git+https://github.com/fecgov/regulations-parser.git@master#egg=regparser
   to:
   -e git+https://github.com/fecgov/[email protected]#egg=regparser
   (The above will point to my updated branch which I will merge into regulations parser if everyone approves this PR)
6. install the requirements.txt: run pip install -r requirements.txt (make sure you're using version 22.0.4 of pip or upgrade according to warning and re-run) (also it will ask you if you want to use the old version or switch and you should type s)
7. remove node_modules: run rm -rf node_modules
8. If you have already parsed on your local (have a src file) run rm -rf src
9. run npm i (you can make sure you're running the proper version with nvm install v.14.15.5)
10. run npm audit fix
11. run npm run build
12. run dropdb eregs-db if the eregs database already exist.
13. run createdb eregs-db (same name as defined in local_settings.py)
    create a new local_settings.py with the following configuration if one doesn't exist:

API_BASE = 'http://localhost:8000/api/'
DATABASES = {
  'default': {
    'ENGINE': 'django.db.backends.postgresql_psycopg2',
    'NAME': 'eregs-db',
    'HOST': '127.0.0.1',
    'PORT': '5432',
  }
}

14. run python manage.py migrate
15. run python manage.py compile_frontend (if you don't already have a compiled folder then mkdir compiled)
16. run python manage.py runserver (leave this running)

Terminal#2:

1. create python 3.7.12 virtualenv for parser: run pyenv virtualenv 3.7.12 venv-parser-3712
2. pyenv activate venv-parser-3712
3. install parser requirements: run pip install -r requirements-parsing.txt (same as above with pip version 22.0.4) NOTE: You will see a warning about networkx being y
4. run snyk test --file=requirements-parsing.txt --package-manager=pip (you should not see the networkx issue anymore, but you will see the django and numpy issues that will be addresssed in [Snyk:High] django SQL Injection (due by 05/13/2022) #681)
5. parser 2021 regs on to local db: run python load_regs/load_fec_regs.py local

This is my first time with e-regs, so please let me know if there's improvements I can make! Constructive criticism super welcome.
