# Deploying Eos
## General
Install the web dependencies.
cd /path/to/Eos/eosweb/core
bower install
Install the Python dependencies. (If doing this in a virtualenv, add the virtualenv path to *.gitignore*.)
cd /path/to/Eos
pip install -r requirements.txt
Build the JavaScript code.
./build_js.sh
## Standalone
Create *local_settings.py*.
cd /path/to/Eos
cp local_settings{.example,}.py
Modify *local_settings.py* as required.
Launch the server.
cd /path/to/Eos
FLASK_APP=eosweb EOSWEB_SETTINGS=$PWD/local_settings.py python -m flask run
Access Eos at http://localhost:5000/.
## Heroku
Add a MongoDB (recommended) or PostgreSQL resource to your Heroku app.
Set up the Heroku app.
heroku git:remote -a your-app-12345
Create *local_settings.py*.
cd /path/to/Eos
cp local_settings{.example,}.py
Modify *local_settings.py* as required. Take special note of `BASE_URI` and the database information.
Set environment variables.
heroku config:set EOSWEB_SETTINGS=/app/local_settings.py
Push the changes to the Heroku app.
git add .
git commit -m 'For Heroku'
git push heroku master
Access Eos at https://your-app-12345.herokuapp.com/.
# Administering an election
There is not yet a GUI for administering an election – this must be done through the command line/Python interface.
## Creating an election
Firstly, access the Flask shell. Locally, run:
FLASK_APP=eosweb EOSWEB_SETTINGS=$PWD/local_settings.py python -m flask shell
If on Heroku, run:
heroku run FLASK_APP=eosweb python -m flask shell
Then create the election using the Python API. For example:
```python
from eos.core.objects import *
from eos.base.election import *
from eos.psr.crypto import *
from eos.psr.election import *
from eos.psr.workflow import *
election = PSRElection()
election.workflow = PSRWorkflow()
# Set election details
election.name = 'Test Election'
#election.kind = 'referendum' # Uncomment this line to change the kind of vote being held
from eos.redditauth.election import RedditUser
election.voters.append(UserVoter(user=EmailUser(name='Alice', email='alice@localhost')))
election.voters.append(UserVoter(user=EmailUser(name='Bob', email='bob@localhost')))
election.voters.append(UserVoter(user=EmailUser(name='Carol', email='carol@localhost')))
election.voters.append(UserVoter(user=RedditUser(username='RunasSudo')))
# At least two mixing trustees are required to preserve ballot secrecy
election.mixing_trustees.append(InternalMixingTrustee(name='Eos Voting'))
election.mixing_trustees.append(InternalMixingTrustee(name='Eos Voting'))
election.sk = EGPrivateKey.generate()
election.public_key = election.sk.public_key
election.questions.append(ApprovalQuestion(prompt='Pineapple on pizza?', choices=[Choice(name='Yes'), Choice(name='No')], min_choices=0, max_choices=1))
# Freeze election
election.workflow.get_task('eos.base.workflow.TaskConfigureElection').enter()
# Open voting
election.workflow.get_task('eos.base.workflow.TaskOpenVoting').enter()
election.save()
```
If you are using the email log in method (`EmailUser`), you can additionally email the log in details using, for example:
```python
for voter in election.voters:
if isinstance(voter, UserVoter):
if isinstance(voter.user, EmailUser):
voter.user.email_password(app.config['SMTP_HOST'], app.config['SMTP_PORT'], app.config['SMTP_USER'], app.config['SMTP_PASS'], app.config['SMTP_FROM'])
```
You should now be able to see the election in the web interface.
Exit the Flask shell by pressing Ctrl+D.
## Administrating an election
Provided that you are logged in using an administrator account (defined using the `ADMINS` option in *local_settings.py*), you will be able to further administer the election from the ‘Administrate this election’ tab in the web interface.
