========================
OpenSlides Development
========================
This instruction helps you to setup a development environment for OpenSlides.
Installation and start of the development version
=================================================
1. Installation on GNU/Linux or Mac OS X
----------------------------------------
a. Check requirements
'''''''''''''''''''''
Make sure that you have installed `Python (>= 3.6) <https://www.python.org/>`_,
`Node.js (>=10.x) <https://nodejs.org/>`_ and `Git <http://git-scm.com/>`_ on
your system. You also need build-essential packages and header files and a
static library for Python.
For Debian based systems (Ubuntu, etc) run::
$ sudo apt-get install git nodejs npm build-essential python3-dev
b. Get OpenSlides source code
'''''''''''''''''''''''''''''
Clone current master version from `OpenSlides GitHub repository
<https://github.com/OpenSlides/OpenSlides/>`_::
$ git clone https://github.com/OpenSlides/OpenSlides.git
$ cd OpenSlides
c. Setup a virtual Python environment (optional)
''''''''''''''''''''''''''''''''''''''''''''''''
See step 1. b. in the installation section in the `README.rst
<https://github.com/OpenSlides/OpenSlides/blob/master/README.rst>`_.
d. Finish the server
''''''''''''''''''''
Install all required Python packages::
$ pip install --requirement requirements.txt
Create a settings file, run migrations and start the server::
$ python manage.py createsettings
$ python manage.py migrate
$ python manage.py runserver
To get help on the command line options run::
$ python manage.py --help
Later you might want to restart the server with one of the following commands.
To start OpenSlides with this command and to avoid opening new browser windows
run::
$ python manage.py start --no-browser
When debugging something email related change the email backend to console::
$ python manage.py start --debug-email
e. Debugging the server
'''''''''''''''''''''''
If you wish to have even further debugging, enable `django-extensions
<https://django-extensions.readthedocs.io/>`_ in the ``settings.py`` by adding
``django_extensions`` to the list of ``INSTALLED_PLLUGINS``. Make sure, you
install the following packages::
$ pip install Werkzeug pyparsing pydot django-extensions
You can start the enhanced debugging-server via::
$ python manage.py runserver_plus
f. Setup and start the client
'''''''''''''''''''''''''''''
Go in the client's directory in a second command-line interface::
$ cd client/
Install all dependencies and start the development server::
$ npm install
$ npm start
Now the client is available under ``localhost:4200``.
If you want to provide the client statically, you can build it via::
$ npm run build
The build client files are availible from the root directory in
``openslides/static`` and can be provided via NGINX.
2. Installation on Windows
--------------------------
Follow the instructions above (Installation on GNU/Linux or Mac OS X) but care
of the following variations.
To get Python download and run the latest `Python 3.7 32-bit (x86) executable
installer <https://www.python.org/downloads/windows/>`_. Note that the 32-bit
installer is required even on a 64-bit Windows system. If you use the 64-bit
installer, step d. of the instruction might fail unless you installed some
packages manually.
In some cases you have to install `MS Visual C++ 2015 build tools
<https://www.microsoft.com/en-us/download/details.aspx?id=48159>`_ before you
install the required python packages for OpenSlides (unfortunately Twisted
needs it).
To setup and activate the virtual environment in step c. use::
> .virtualenv\Scripts\activate.bat
All other commands are the same as for GNU/Linux and Mac OS X.
3. Running the test cases
-------------------------
a. Running server tests
'''''''''''''''''''''''
To run some server tests see `.travis.yml
<https://github.com/OpenSlides/OpenSlides/blob/master/.travis.yml>`_.
You can generate an class-structure image when having `django_extensions`
enabled (see above)::
$ python manage.py graph_models -a -g -o my_project_visualized.png
b. Client tests and commands
''''''''''''''''''''''''''''
Change to the client's directory to run every client related command. Run
client tests::
$ npm test
Fix the code format and lint it with::
$ npm run prettify-write
$ npm run lint
To extract translations run::
$ npm run extract
When updating, adding or changing used packages from npm, please update the
README.md using following command::
$ npm run licenses
OpenSlides in big mode
======================
To install OpenSlides for big assemblies (in 'big mode') you have to setup some
additional components and configurations. In the 'big mode' you should use a webserver
like NGINX to serve the static and media files as proxy server in front of your OpenSlides
interface server. You should also use a database like PostgreSQL. Use Redis as channels backend,
cache backend and session engine. Finally you should use gunicorn with uvicorn as interface server.
1. Install and configure PostgreSQL and Redis
---------------------------------------------
Install `PostgreSQL <https://www.postgresql.org/>`_ and `Redis
<https://redis.io/>`_. For Ubuntu 18.04 e. g. run::
$ sudo apt-get install postgresql libpq-dev redis-server
Be sure that database and redis server is running. For Ubuntu 18.04 e. g. this
was done automatically if you used the package manager.
Then add database user and database. For Ubuntu 18.04 e. g. run::
$ sudo -u postgres createuser --pwprompt --createdb openslides
$ sudo -u postgres createdb --owner=openslides openslides
2. Change OpenSlides settings
-----------------------------
Create OpenSlides settings file if it does not exist::
$ python manage.py createsettings
Change OpenSlides settings file (usually called settings.py): Setup
`DATABASES` entry as mentioned in the settings file. Set `use_redis` to
`True`.
Populate your new database::
$ python manage.py migrate
3. Run OpenSlides
-----------------
To start Daphne run::
$ export DJANGO_SETTINGS_MODULE=settings
$ export PYTHONPATH=personal_data/var/
$ daphne -b 0.0.0.0 -p 8000 openslides.asgi:application
The last line may be interchangeable with gunicorn and uvicorn as protocol
server::
$ gunicorn -w 4 -b 0.0.0.0:8000 -k uvicorn.workers.UvicornWorker openslides.asgi:application
4. Use NGINX (optional)
-----------------------
When using NGINX as a proxy for delivering static files the performance of the
setup will increase.
This is an example ``nginx.conf`` configuration for Daphne listing on port
8000::
worker_processes 1;
events {
worker_connections 1024;
}
http {
server {
listen 80;
server_name localhost;
root $YOUR_OS_ROOT_FOLDER/openslides/static;
index index.html index.htm;
include /etc/nginx/mime.types;
client_max_body_size 100M;
gzip on;
gzip_min_length 1000;
gzip_proxied expired no-cache no-store private auth;
gzip_types text/plain text/css application/json application/javascript application/x-javascript text/xml application/xml application/xml+rss text/javascript;
location / {
try_files $uri $uri/ /index.html;
}
location /apps {
proxy_pass http://localhost:8000;
}
location /media {
proxy_pass http://localhost:8000;
}
location /rest {
proxy_pass http://localhost:8000;
}
location /ws {
proxy_pass http://localhost:8000;
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "Upgrade";
}
}
}

OpenSlides
============
What is OpenSlides?
===================
OpenSlides is a free, web based presentation and assembly system for
managing and projecting agenda, motions and elections of an assembly. See
https://openslides.com for more information.
Installation
============
The OpenSlides server runs everywhere where Python is running (for example on
GNU/Linux, Mac or Windows). For the OpenSlides client a current web browser is required.
1. Installation on GNU/Linux or Mac OS X
----------------------------------------
a. Check requirements
'''''''''''''''''''''
Make sure that you have installed `Python (>= 3.6) <https://www.python.org/>`_
on your system.
Additional you need build-essential packages, header files and a static
library for Python and also the pyvenv-3 binary package for python3.
E.g. run on Debian/Ubuntu::
$ sudo apt-get install build-essential python3-dev python3-venv
b. Setup a virtual Python environment (optional)
''''''''''''''''''''''''''''''''''''''''''''''''
You can setup a virtual Python environment using the virtual environment
(venv) package for Python to install OpenSlides as non-root user.
Create your OpenSlides directory and change to it::
$ mkdir OpenSlides
$ cd OpenSlides
Setup and activate the virtual environment::
$ python3 -m venv .virtualenv
$ source .virtualenv/bin/activate
$ pip install --upgrade setuptools pip
c. Install OpenSlides
'''''''''''''''''''''
To install OpenSlides just run::
$ pip install openslides
This installs the latest stable version. To install a specific (beta)
version use ``openslides==x.y``.
You can also use the package from the `OpenSlides website
<https://openslides.com/>`_. Download latest OpenSlides release as
compressed tar archive and run::
$ pip install openslides-x.y.tar.gz
This will install all required Python packages (see
``requirements/production.txt``).
d. Start OpenSlides
'''''''''''''''''''
To start OpenSlides simply run::
$ openslides
If you run this command the first time, a new database and the admin account
(Username: ``admin``, Password: ``admin``) will be created. Please change the
password after first login!
OpenSlides will start a webserver. It will also try to open the webinterface in
your default webbrowser. The server will try to listen on the local ip address
on port 8000. That means that the server will be available to everyone on your
local network (at least for commonly used network configurations).
If you use a virtual environment (see step b.), do not forget to activate
the environment before restart after you closed the terminal::
$ source .virtualenv/bin/activate
To get help on the command line options run::
$ openslides --help
You can store settings, database and other personal files in a local
subdirectory and use these files e. g. if you want to run multiple
instances of OpenSlides::
$ openslides start --local-installation
2. Installation on Windows
--------------------------
Follow the instructions above (1. Installation on GNU/Linux or Mac OS X) but care
of the following variations.
To get Python download and run the latest `Python 3.7 32-bit (x86) executable
installer <https://www.python.org/downloads/windows/>`_. Note that the 32-bit
installer is required even on a 64-bit Windows system. If you use the 64-bit
installer, step 1c of the instruction might fail unless you installed some
packages manually.
In some cases you have to install `MS Visual C++ 2015 build tools
<https://www.microsoft.com/en-us/download/details.aspx?id=48159>`_ before you
install the required python packages for OpenSlides (unfortunately Twisted
needs it).
To setup and activate the virtual environment in step 1b use::
> .virtualenv\Scripts\activate.bat
All other commands are the same as for GNU/Linux and Mac OS X.
3. Installation with Docker
---------------------------
The installation instruction for (1) and (2) described a way to use OpenSlides in a
'small mode' with max 10 concurrent clients. To install OpenSlides for big assemblies
('big mode') you have to setup some additional components and configurations.
The easiest way to run the OpenSlides 'big mode' environment (with PostgreSQL, Redis
and NGINX) with Docker Compose: use our docker compose suite. Follow the instruction in
the `openslides-doccker-compose Repository <https://github.com/OpenSlides/openslides-docker-compose>`_.
To install and configure all components of our 'big mode' manually you can read the
`big-mode-instruction <https://github.com/OpenSlides/OpenSlides/blob/master/DEVELOPMENT.rst#openslides-in-big-mode>`_
Configuration
=============
Please consider reading the `OpenSlides configuration
<https://github.com/OpenSlides/OpenSlides/blob/master/SETTINGS.rst>`_ page to
find out about all configurations, especially when using OpenSlides for big
assemblies.
Development
===========
To setup a development environment for OpenSlides follow the instruction of
`DEVELOPMENT.rst
<https://github.com/OpenSlides/OpenSlides/blob/master/DEVELOPMENT.rst>`_.
Used software
=============
OpenSlides uses the following projects or parts of them:
* Several Python packages (see ``requirements/production.txt`` and ``requirements/big_mode.txt``).
* Several JavaScript packages (see ``client/package.json``)
License and authors
===================
OpenSlides is Free/Libre Open Source Software (FLOSS), and distributed
under the MIT License, see ``LICENSE`` file. The authors of OpenSlides are
mentioned in the ``AUTHORS`` file.

@ -1,125 +0,0 @@
==========================
OpenSlides configuration
==========================
First, locate your `settings.py`. Since this is a regular python file,
experienced users can also write more advanced configurations with e.g. swithing
between two sets of configs. This also means, that the syntax need to be correct
for OpenSlides to start.
All presented settings must be written `<SETTINGS_NAME> = <value>` to follow the
correct syntax.
The `settings.py` is just an extension for Django settings. Please visit the
`Django settings documentation
<https://docs.djangoproject.com/en/2.2/ref/settings/>`_ to get an overview about
all existing settings.
SECURITY
========
For `DEBUG` and `SECRET_KEY` see the sections in the django settings
documenataion.
`RESET_PASSWORD_VERBOSE_ERRORS`: Default: `True`. Set to `False` to disable.
Controls the verbosity on errors during a reset password. If enabled, an error
will be shown, if there does not exist a user with a given email address. So one
can check, if a email is registered. If this is not wanted, disable verbose
messages. An success message will always be shown.
`AUTH_PASSWORD_VALIDATORS`: Add custom password validators, e.g. a min-length
validator. See `django auth docs
<https://docs.djangoproject.com/en/2.2/topics/auth/passwords/#module-django.contrib.auth.password_validation>`_
for mor information.
Directories
===========
`OPENSLIDES_USER_DATA_DIR`: The path, where all user data is saved, like static
files, mediafiles and the default database. This path can be different to the
location of the `settings.py`.
`STATICFILES_DIRS` and `STATIC_ROOT`: Managing static files. Because the clint
is not delivered by the server anymore, these settings are obsolete.
`MEDIA_ROOT`: The location of mediafiles. The default is a `media` folder inside
`OPENSLIDES_USER_DATA_DIR`, but can be altered to another path.
Email
=====
Please refer to the Django settings documentation. A changed email backend is
useful for debugging to print all email the the console::
EMAIL_BACKEND = 'django.core.mail.backends.console.EmailBackend'
Logging
=======
To setup basic logging see `logging
<https://docs.djangoproject.com/en/2.2/topics/logging/>`_.
We recommend to enable all OpenSlides related logging with level `INFO` per
default::
LOGGING = {
'formatters':
'lessnoise': {
'format': '[{levelname}] {name} {message}',
'style': '{',
'datefmt': '[%Y-%m-%d %H:%M:%S %z]',
},
},
'handlers': {
'console': {
'class': 'logging.StreamHandler',
'formatter': 'lessnoise',
},
},
'loggers': {
'openslides': {
'handlers': ['console'],
'level': os.getenv('OPENSLIDES_LOG_LEVEL', 'INFO'),
},
},
}
With the environment variable `OPENSLIDES_LOG_LEVEL` the level can be adjusted
without changing the `settings.py`.
Big mode and caching
====================
When running multiple workers redis is required as a message broker between the
workers. Set `use_redis = True` to enable redis and visit `OpenSLides in big
mode
<https://github.com/OpenSlides/OpenSlides/blob/master/DEVELOPMENT.rst#openslides-in-big-mode>`_.
When seting `use_redis = True`, three settings are important:
- Caching: `REDIS_ADDRESS` is used to provide caching with redis across all
workers.
- Channels: The "message queue" for the workers. Adjust the `hosts`-part to the
redis address.
- Sessions: All sessions are managed in redis to ensure them across all workers.
Please adjust the `SESSION_REDIS` fields to point to the redis instance.
Advanced
========
`PING_INTERVAL` and `PING_TIMEOUT` are settings for the clients how frequently
to ping the server (interval) and how big is the timeout. If a ping took longer
than the timeout, the clients does a forced reconnect.
`COMPRESSION`: Enable or disables the compression when sending data. This does
not affect the client.
`PRIORITIZED_GROUP_IDS`: A list of group ids. If one client is logged in and the
operator is in one of these groups, the client disconnected and reconnects again.
All requests urls (including websockets) are now prefixed with `/prioritize`, so
these requests from "prioritized clients" can be routed to different servers.

# OpenSlides 3 Client
Prototype application for OpenSlides 3.0 (Client).
Currently under constant heavy maintenance.
## Development Info
As an Angular project, Angular CLI is highly recommended to create components and services.
See https://angular.io/guide/quickstart for details.
### Contribution Info
Please respect the code-style defined in `.editorconf` and `.pretierrc`.
Code alignment should be automatically corrected by the pre-commit hooks.
Adjust your editor to the `.editorconfig` to avoid surprises.
See https://editorconfig.org/ for details.
### Pre-Commit Hooks
Before commiting, new code will automatically be aligned to the definitions set in the
`.prettierrc`.
Furthermore, new code has to pass linting.
Our pre-commit hooks are:
`pretty-quick --staged` and `lint`
See `package.json` for details.
### Documentation Info
The documentation can be generated by running `npm run compodoc`.
A new web server will be started on http://localhost:8080
Once running, the documentation will be updated automatically.
You can run it on another port, with adding your local port after the
command. If no port specified, it will try to use 8080.
Please document new code using JSDoc tags.
See https://compodoc.app/guides/jsdoc-tags.html for details.
### Development server
Run `npm start` for a development server. Navigate to `http://localhost:4200/`.
The app will automatically reload if you change any of the source files.
A running OpenSlides (2.2 or higher) instance is expected on port 8000.
Start OpenSlides as usual using
`python manage.py start --no-browser --host 0.0.0.0`
### Translation
We are using ngx-translate for translation purposes.
Use `npm run extract` to extract strings and update elements an with translation functions.
Language files can be found in `/src/assets/i18n`.
