Installation instructions

Basic guide

Non-operating system specific path names are represented using the linux convention of a / separator. If you are installing in a Windows environment you will need to use the Windows \ separator.

Installation prerequisites

Install python 2.7

Install setuptools and pip


Before continuing, consider virtualenv

Install OpenREM

  • pip install openrem (Needs internet connection)

Configure OpenREM

Locate install location

  • Linux: /usr/lib/python2.7/dist-packages/openrem/ or /usr/lib/python2.7/site-packages/openrem/
  • Windows: C:\Python27\Lib\site-packages\openrem\

There are two files that need renaming: (changed for 0.4.0)

  • openrem/ to openrem/
  • openrem/ to openrem/

In the file, set the database details.

For testing you can use the SQLite3 database:

'ENGINE': 'django.db.backends.sqlite3',
  • Linux example: 'NAME': '/var/openrem/openrem.db',
  • Windows example: 'NAME': 'C:\Documents\User\OpenREM\openrem.db',

For production use, see Database options below

Generate a new secret key and replace the one in the file. You can use for this.

Create the database

  • Linux: python /usr/lib/python2.7/dist-packages/openrem/ syncdb
  • Windows: python C:\Python27\Lib\site-packages\openrem\ syncdb

Answer each question as it is asked, do setup a superuser. This username and password wil be used to log into the admin interface to create the usernames for using the web interface. See the Start using it! section below.

Help! I get a value too long for type character varying(50) error!
This error with part of the Django auth_permissions system that we are not using, and can safely be ignored. This is being tracked as Issue 62

For production installs, convert to South (What is south?)

  • Linux: python /usr/lib/python2.7/dist-packages/openrem/ convert_to_south remapp
  • Windows: python C:\Python27\Lib\site-packages\openrem\ convert_to_south remapp

Start test web server

  • Linux: python /usr/lib/python2.7/dist-packages/openrem/ runserver
  • Windows: python C:\Python27\Lib\site-packages\openrem\ runserver

If you are using a headless server and need to be able to see the web interface from another machine, use python /usr/lib/python2.7/dist-packages/openrem/ runserver x.x.x.x:8000 (or Windows equivalent) replacing the x with the IP address of the server and 8000 with the port you wish to use.

Open the web addesss given, appending /openrem (http://localhost:8000/openrem)

Start using it!

Add some data! (See the Importing data to OpenREM for adding the scripts to the path if this doesn’t work)

  • rdsrfile.dcm

Add some users (New in version 0.4.0)

  • Go to the admin interface (eg http://localhost:8000/admin) and log in with the user created when you created the database (syncdb)

  • Create some users and add them to the appropriate groups (if there are no groups, go to the OpenREM homepage and they should be created).

    • viewgroup can browse the data only
    • exportgroup can do as view group plus export data to a spreadsheet, and will be able to import height and weight data in due course (See Issue #21)
    • admingroup can delete studies in addition to anything the export group can do

Further instructions

Database options

SQLite is great for getting things running quickly and testing if the setup works, but is really not recommended for production use on any scale. Therefore it is recommended to use a different database such as PostgreSQL or MySQL.

Here are instructions for installing PostgreSQL on linux and on Windows:

Database migrations

South is a django application to manage database migrations. Using South means that future changes to the database model can be calculated and executed automatically with simple commands when OpenREM is upgraded.

Production webservers

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.

Virtualenv and virtualenvwrapper

If the server is to be used for more than one python application, or you wish to be able to test different versions of OpenREM or do any development, it is highly recommended that you use virtualenv or maybe virtualenvwrapper

Virtualenv sets up an isolated python environment and is relatively easy to use.

If you do use virtualenv, all the paths referred to in the documentation will be changed to:

  • Linux: lib/python2.7/site-packages/openrem/
  • Windows: Lib\site-packages\openrem
