## Install OSEM
You can run rails apps in different modes (development, production). For more information
about rails and what it can do, see the [rails guides.](http://guides.rubyonrails.org/getting_started.html)
### Run OSEM in development
We are using [Vagrant](https://www.vagrantup.com/) to create our development environments.
1. Install [Vagrant](https://www.vagrantup.com/downloads.html) and [VirtualBox](https://www.virtualbox.org/wiki/Downloads). Both tools support Linux, MacOS and Windows.
2. Install [vagrant-exec](https://github.com/p0deje/vagrant-exec):
```
vagrant plugin install vagrant-exec
vagrant plugin install vagrant-reload
```
3. Clone this code repository:
```
git clone https://github.com/openSUSE/osem.git
```
4. Execute Vagrant:
```
vagrant up
```
5. Start your OSEM rails app:
```
vagrant exec rails server -b 0.0.0.0
```
6. Check out your OSEM rails app:
You can access the app [localhost:3000](http://localhost:3000). Whatever you change in your cloned repository will have effect in the development environment. Sign up, the first user will be automatically assigned the admin role.
7. Changed something? Test your changes!:
```
vagrant exec rake test
```
8. Explore the development environment:
```
vagrant ssh
```
9. Or issue any standard `rails`/`rake`/`bundler` command by prepending `vagrant exec`
```
vagrant exec rake db:migrate
```
**Note**: We use [letter_opener](https://github.com/ryanb/letter_opener) in development environment.
However, letter_opener uses launchy to present the emails in your browser which doesn't work in combination with Vagrant.
Therefore we use [letter_open_web](https://github.com/fgrehm/letter_opener_web).
You can check out your mails by visiting [localhost:3000/letter_opener](http://localhost:3000/letter_opener) if you use Vagrant.
### Run OSEM in production
We recommend to run OSEM in production with [mod_passenger](https://www.phusionpassenger.com/download/#open_source)
# Install Open Source Event Manager
OSEM is a *Ruby on Rails* application. We recommend to run OSEM in production with [mod_passenger](https://www.phusionpassenger.com/download/#open_source)
and the [apache web-server](https://www.apache.org/). There are tons of guides on how to deploy rails apps on various
base operating systems. Check Google ;-)
#### ImageMagick
We use imagemagic for image manipulation of sponsor logo. You can get it from [direct install](http://software.opensuse.org/package/ImageMagick) page of the package or else check out [Download page](http://www.imagemagick.org/script/binary-releases.php) of ImageMagick.
For more information about rails and what it can do, see the [rails guides.](http://guides.rubyonrails.org/getting_started.html)
If you are upgrading your osem instance and would like to resize the exisiting logos, you would need to `reprocess!` the images. You can do it by running the following rake task:
```
## Dependency for ImageMagick
We use [ImageMagick](http://imagemagick.org/) for image manipulation so it needs to be available in your installation.
If you would like to resize exisiting logos in your OSEM installation you can do so by running the following rake task:
```shell
$ rake logo:reprocess
```
#### Use openID
In order to use the OpenID feature you need to register your application with the providers
(Google and Facebook) and enter their API keys in config/secrets.yml file, changing the existing sample values.
You can register as a developer with Google from https://code.google.com/apis/console#:access
You can register as a developer with Facebook from https://developers.facebook.com/,
by selecting from the top menu the option 'Apps' -> 'Create a New App'
Unless you add the key and secret for each provider, you will not be able to see the image that
redirects to the login page of the provider.
If you add a provider that does not require developers to register their application, you still need
to create two (2) variables, in config/secrets.yml
with the format of providername_key and providername_secret and add some sample text as their values.
Example:
myprovider_key = 'sample data'
myprovider_secret = 'sample data'
That is required so that the check in app/views/devise/shared/_openid.html.haml will pass and
the image-link to login using the provider will be shown.
## Using openID
In order to use [openID](http://openid.net/) logins for your OSEM installation you need to register your application with the providers ([Google](https://code.google.com/apis/console#:access), GitHub or [Facebook](https://developers.facebook.com/)) and enter their API keys in `config/secrets.yml` file, changing the existing sample values.
#### Email Notifications
Check your service provider smtp settings and set the following variables in `config.yml` file:
```
mail_address: 'smtp.host.com'
mail_port: 587
mail_username: 'username@host.com'
mail_password: 'password'
mail_authentication: 'plain'
```
## Reocuring Jobs
Open a separate terminal and go into the directory where the rails app is present, and type the following to start the delayed_jobs worker for sending email notifications.
```
rake jobs:work
```
### Using iChain in test mode
[devise_ichain_authenticatable](https://github.com/openSUSE/devise_ichain_authenticatable) comes with
test mode, which can be useful in development phase in which an iChain proxy is not usually configured or even available. You can enable ichain authentication by setting `CONFIG['authentication']['ichain']['enabled']` equal to `true` in `config.yml` file. You would also need to set following options in `devise.rb`:
```Ruby
# Activate the test mode
config.ichain_test_mode = true
# 'testuser' user will be permanently signed in.
config.ichain_force_test_username = "testuser"
# set email of 'testuser'
config.ichain_force_test_attributes = {:email => "testuser@example.com"}
bundle exec rake jobs:work
```
