Configuration Guidelines

How to configure a new instance.

Switch to an alternate GitHub repo

If you wish to update your site from an alternate github repo this can be done using:

cd ~web2py/applications/eden
git remote set-url origin

(replace 'username' & 'eden' as-required)

'pull' assumes that the appropriate management script is installed, otherwise can use the individual commands contained therein: git pull, etc

File Permissions

Note: As of January 2012, BZR/Launchpad info for eden is deprecated. Please visit the GitHub page. Thanks.

For Linux installations only.

chown web2py ~web2py/applications/admin/cron
chown web2py ~web2py/applications/admin/cron/crontab
chown web2py ~web2py/applications/admin/cache/
chown web2py ~web2py/applications/admin/databases/
chown web2py ~web2py/applications/admin/errors/
chown web2py ~web2py/applications/admin/sessions/
chown web2py ~web2py/applications/admin/uploads/
cd web2py/applications
bzr branch lp:sahana-eden eden
chown web2py eden/cron
chown web2py eden/cache/
chown web2py eden/databases/
chown web2py eden/errors/
chown web2py eden/sessions/
chown web2py eden/static/img/markers
chown web2py eden/static/scripts/tools
chown web2py eden/static/styles/S3/sahana.css
chown web2py eden/static/styles/S3/sahana.min.css
chown web2py eden/uploads/
mkdir eden/uploads/gis_cache
mkdir eden/uploads/images
mkdir eden/uploads/tracks
chown web2py eden/uploads/gis_cache
chown web2py eden/uploads/images
chown web2py eden/uploads/tracks

Useful Aliases

For Linux installations only.

vim ~/.bashrc
alias w2p='cd ~web2py;sudo -H -u web2py python -S eden -M'
alias compile='cd ~web2py;python -S eden -R applications/eden/static/scripts/tools/'
alias pull="cd ~web2py/applications/eden;sed -i 's/deployment_settings.base.migrate = False/deployment_settings.base.migrate = True/g' models/;bzr pull;rm -rf compiled;cd ~web2py;sudo -H -u web2py python -S eden -M -R applications/eden/static/scripts/tools/;/etc/init.d/apache2 force-reload"
alias migrateoff="sed -i 's/deployment_settings.base.migrate = True/deployment_settings.base.migrate = False/g' ~web2py/applications/eden/models/"

Easier to maintain as scripts (see attached)

Database Setup

Production system should use MySQL:

  • Edit models/


Before the 1st login, edit models/

deployment_settings.auth.hmac_key = "akeytochange"


By default the 1st user to register will gain the Administrator role.

All other users have just the 'Authenticated' level of access, which by default allows full Read/Update/Delete access to all records.

If allowing public self-registration, then you probably want to enable 'Editor' secturiy policy (Administration menu | Settings) which means that the general public can add records (& modify their own) but cannot modify other records.

To add roles to users, go to the Administration menu & within User Management choose 'Membership'.

Security policy is initially defined in models/ but then subsequently managed via the database.

Configurable Options

These can be set via

In time these will be configured by Web Setup.

Some options are currently only configurable via editing models/

deployment_settings.auth.registration_requires_verification = False
deployment_settings.auth.registration_requires_approval = False
deployment_settings.base.public_url = ""
deployment_settings.base.migrate = True
deployment_settings.mail.server = ""
deployment_settings.mail.sender = ""
deployment_settings.mail.approver = ""
deployment_settings.L10n.utc_offset = "UTC +0000"

We would like to expose these to a Web Setup, although it's low priority as these are mostly installation-time decisions.

Disable unnecessary modules, which is currently done in models/

Can also reorganise the Applications menu completely to better display those relevant to the instance:

  • edit file models/
  • section: s3.menu_modules

If you wish to hide some fields which you don't want to confuse your system, then you can do something like this models/ instead of amending the main model (this means that future merges from trunk won't clobber your changes):

# Hide unnecessary fields
tablename = 'pr_person'
table = db[table]
table.pr_pe_label.readable = False
table.pr_pe_label.writable = False
table.local_name.readable = False
table.local_name.writable = False
table.opt_pr_gender.readable = False
table.opt_pr_gender.writable = False
table.opt_pr_age_group.readable = False
table.opt_pr_age_group.writable = False = False = False
table.mobile_phone.readable = False
table.mobile_phone.writable = False
table.date_of_birth.readable = False
table.date_of_birth.writable = False
table.opt_pr_nationality.readable = False
table.opt_pr_nationality.writable = False
table.opt_pr_country.readable = False
table.opt_pr_country.writable = False
table.opt_pr_religion.readable = False
table.opt_pr_religion.writable = False
table.opt_pr_marital_status.readable = False
table.opt_pr_marital_status.writable = False
table.occupation.readable = False
table.occupation.writable = False

Mapping Options


Default Map Portal:

  • Lat
  • Lon
  • Zoom

Bounds of relevant area:

  • Min Lon
  • Max Lat
  • Min Lon
  • Max Lat

Selecting Base Layers:

Test out whether OpenStreetMap, Google, Yahoo or Bing have the best road maps & Satellite imagery

API Keys for Google, Yahoo & MultiMap layers:

For *, we can use this Google Key:


Import Admin Boundaries:

Ticket Viewer

Add the following to of your web2py installation for pretty error pages & the ability to view Tickets.

  • copy from, if one doesn't yet exist.
default_application = 'eden'
default_controller = 'default'
default_function = 'index'
routes_onerror = [
        ('eden/400', '!'),
        ('eden/401', '!'),
        ('eden/*', '/eden/errors/index'),
        ('*/*', '/eden/errors/index'),

favicon.ico & robots.txt

These can be provided via 2 different means:

  • mod_rewrite
    DocumentRoot /home/web2py/applications
    RewriteEngine On
    RewriteRule .*favicon.*\.ico$ /eden/static/favicon.ico [L]
    RewriteRule .*robots\.txt$ /eden/static/robots.txt [L]
    RewriteRule ^/$ /eden/ [R]
  • web2py/ copy & edit


Ensure these files are writable by the webserver:

chown www-data /path/to/web2py/applications/eden/static/scripts/tools
chown www-data /path/to/web2py/applications/eden/static/styles/S3/sahana.css
chown www-data /path/to/web2py/applications/eden/static/styles/S3/sahana.min.css

Colour scheme:


  • copy new logo to static/img
  • point to this using Admin Panel


  • amend views/footer.html


Internet Hosting

Can switch to having users download files from CDNs instead of your server.
This can improve performance in 2 ways:

jQuery from Google by uncommenting the line in views/sahana_scripts_min.html

ext-all.js & ext-all.css from Cachefly by uncommenting the lines in views/gis/gis_scripts_min.html & views/gis/ol_js_loaders.html

Performance Optimisation

  • Disable DB migrations in models/
    deployment_settings.base.migrate = False
    deployment_settings.base.prepopulate = False
  • Use a CDN for public sites models/
    deployment_settings.base.cdn = True
  • Remove comments & unused code from views/layout.html & views/s3_include_min.html
  • Set modules to load from a hardcoded app name instead of substituting request.application in models/
  • Bytecode compile the application:
    cd /home/web2py
    python -S eden -M -R applications/eden/static/scripts/tools/
  • Use MySQL or PostgreSQL instead of SQLite
    • Create Indexes on commonly-accessed tables

Static Home Page

In order to improve performance & scalability, you may wish to set a page (usually the homepage) as static. To do this:

  1. Visit the page in a browser & Save to /static/index.html
  2. Edit the page to remove anything unnecessary (e.g. Ext)
  3. Adjust paths to ../ instead of /eden/ if you wish the app to remain portable
    • include the Language selector dropdown, if-used
  4. Configure the Web server to redirect to this static page for unregistered users:
  5. Remember to maintain this page if you make changes to the main page!
