Install OpenREM 0.7 beta version¶
This is a beta version for developer testing. It is not suitable for general use, and the instructions below are likely to be incorrect.
pip install openrem==0.7.0b10
Will need ``sudo`` or equivalent if installing on linux without using a virtualenv
Locate install location¶
- Ubuntu linux:
- Other linux:
- Linux virtualenv:
- Windows virtualenv:
There are two files that need renaming:
Windows notepad will not recognise the Unix style line endings. Please use an editor such as Notepad++ or Notepad2 if you can, else use WordPad – on the View tab you may wish to set the Word wrap to ‘No wrap’
In local_settings.py, always use forward slashes and not backslashes, even for paths on Windows systems.
SQLite is great for getting things running quickly and testing if the setup works, but is not recommended for production use.
We recommend using PostgreSQL as it is the best supported database for Django, and the only one for which the median value will be calculated and displayed in OpenREM charts. Alternatively, other databases such as MySQL/MariaDB, Oracle, and some others with lower levels of support can be used.
There are some further guides to setting up PostgreSQL – see Database guides below
If you are using SQLite:
'ENGINE': 'django.db.backends.sqlite3', 'NAME': '/ENTER/PATH/WHERE/DB/FILE/CAN/GO',
- Linux example:
- Windows example:
If you are using PostgreSQL:
'ENGINE': 'django.db.backends.postgresql_psycopg2', 'NAME': 'openremdb', 'USER': 'openremuser', 'PASSWORD': 'openrem_pw',
Location for imports and exports¶
Csv and xlsx study information exports and patient size csv imports are
written to disk at a location defined by
The path set for
MEDIA_ROOT is up to you, but the user that runs the
webserver must have read/write access to the location specified because
it is the webserver than reads and writes the files. In a debian linux,
this is likely to be www-data for a production install. Remember to use
forward slashes for the config file, even for Windows.
MEDIA_ROOT = "/var/openrem/media/"
MEDIA_ROOT = "C:/Users/myusername/Documents/OpenREM/media/"
Generate a new secret key and replace the one in the
local_settings.py file. You can use
http://www.miniwebtool.com/django-secret-key-generator/ for this.
ALLOWED_HOSTS needs to be defined, as the
DEBUG mode is now
False. This needs to contain the server name or IP address that
will be used in the URL in the web browser. For example:
ALLOWED_HOSTS = [ '192.168.56.102', '.doseserver.', 'localhost', ]
A dot before a hostname allows for subdomains (eg www.doseserver), a dot
after a hostname allows for FQDNs (eg doseserver.ad.trust.nhs.uk).
Alternatively, a single
'*' allows any host, but removes the security
the feature gives you.
Create the database¶
In a shell/command window, move into the openrem folder:
- Ubuntu linux:
- Other linux:
Create the database:
python manage.py makemigrations remapp python manage.py migrate python manage.py showmigrations
The last command will list each Django app migrations. Each should have a cross inside a pair of square brackets something like below:
admin [X] 0001_initial auth [X] 0001_initial [X] 0002_alter_permission_name_max_length [X] 0003_alter_user_email_max_length [X] 0004_alter_user_username_opts [X] 0005_alter_user_last_login_null [X] 0006_require_contenttypes_0002 contenttypes [X] 0001_initial [X] 0002_remove_content_type_name remapp [X] 0001_initial sessions [X] 0001_initial sites [X] 0001_initial
Finally, create a Django super user:
python manage.py createsuperuser
Answer each question as it is asked – this user is needed to set up the other users and the permissions.
Add the median database function: PostgreSQL databases only¶
Rename the file
and then run
python manage.py makemigrations --empty remapp python manage.py migrate
The first command will create a skeleton
0001_initial.py migration file. The
second command runs the migration files, and will display the text
Applying remapp.0002_fresh__openrem_install_add_median_function... OK, indicating
that the median function has been added.
Start all the services!¶
You are now ready to start the services to allow you to use OpenREM - go to Start all the services to see how!
Here are instructions for installing PostgreSQL on linux and on Windows, and guides to backup up PostgreSQL and MySQL:
Unlike the database, the production webserver can be left till later and can be changed again at any time.
For performance it is recommended that a production webserver is used instead of the inbuilt ‘runserver’. Popular choices would be either Apache or you can do as the cool kids do and use Gunicorn with nginx.
The django website has instructions and links to get you set up with Apache.
An advanced guide using Apache, including auto-restarting the server when the code changes, has been contributed here: Installing Apache on Windows Server 2012 with auto-restart
