Configuration Guidelines
How to configure a new instance.
Changing the Template
To change the instance's Sahana template:
# Initially <OLD TEMPLATE> = default # You can also edit the config file directly: /home/prod/eden/models/000_config.py sed-i '|template = "<OLD TEMPLATE>"|template = "<NEW TEMPLATE>"|' /home/prod/eden/models/000_config.py compile # This will delete all current data and pre-populate from the new template clean
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 https://github.com/USERNAME/eden.git pull
(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.

Easier to maintain as scripts (see attached)
Database Setup
Production system should use MySQL or PostgreSQL:
- Edit
models/000_config.py
Security
Before the 1st login, edit models/000_config.py
:
deployment_settings.auth.hmac_key = "akeytochange"
Roles
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/zzz_1st_roles.py
but then subsequently managed via the database.
Configurable Options
Basic Options
These can be set via http://127.0.0.1:8000/sahana/admin/setting/1/update
- Admin Name/Email/Tel
In time these will be configured by Web Setup.
Some options are currently only configurable via editing models/000_config.py
:
deployment_settings.auth.registration_requires_verification = False deployment_settings.auth.registration_requires_approval = False deployment_settings.base.public_url = "http://127.0.0.1:8000" deployment_settings.base.migrate = True deployment_settings.mail.server = "127.0.0.1:25" deployment_settings.mail.sender = "sahana@your.org" deployment_settings.mail.approver = "useradmin@your.org" 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.
Modules and Menu
Disable unnecessary modules, which is currently either done in models/000_config.py
or in the template's config.py
file. Active modules are stored in settings.modules, which is an instance of OrderedDict. The key of each item in this OrderedDict is the name of the module (a string), and each value is an instance of Storage. To disable a module, either comment out the relevant lines of config.py
in the template, where the list is populated, or else use the pop method in models/000_config.py
to remove the relevant item from settings.modules.
Can also reorganise the Applications menu completely to better display those relevant to the instance:
Table Fields
If you wish to hide some fields which you don't want to confuse your system, then you can do something like this models/zzz_local.py
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 table.email.readable = False table.email.writable = 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
Registration Message Options
The welcome message and other messages relating to registration and logging in are in current.auth.messages
which can be configured in a customise_auth_user_resource()
function in your template's config.py
file.
To see the messages that can be changed, look for the messages.*
lines in the AuthS3.__init__
function in modules/s3/s3aaa.py
.
These also show examples of using format elements like %(system_name)s
to insert the system name, url, user name, and link to the user's profile. Use the same format elements in your messages to have those inserted.
Example:
def customise_auth_user_resource(r, resource): messages = current.auth.messages messages.welcome_email_subject = "Welcome to %(system_name)s!" messages.welcome_email = \ """Welcome to %(system_name)s, %(first_name) %(last_name)! * You can start using %(system_name)s at: %(url)s * To edit your profile go to: %(url)s%(profile)s Thank you for registering!""" settings.customise_auth_user_resource = customise_auth_user_resource
These messages do not need T( )
around them. If a translation is required they need adding to the languages/xx.py file.
As-usual, for a site with multiple languages, it is suggested to include the original message in English to serve as the key in the translation files, and to include the format elements (for system name, etc.) in the message, so that the translator can rearrange them as needed.
Mapping Options
http://localhost:8000/sahana/gis/config/update/1
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 *.sahanafoundation.org, we can use this Google Key:
- ABQIAAAAgB-1pyZu7pKAZrMGv3nksRR1-chREdZE62d-MGawPNPOGidOJBQQCwHsElsSGbD5VMpNj7DBMNxjTg
Import Admin Boundaries:
- The locations hierarchy should be populated with L0->L3 data, which are often available in the form of shapefiles
Ticket Viewer
Add the following to routes.py
of your web2py installation for pretty error pages & the ability to view Tickets.
- copy from
routes.example.py
, if one doesn't yet exist.
#!/usr/bin/python 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/routes.py
: copyroutes.example.py
& edit
Themes
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:
- select using Admin Panel:
Logo:
- copy new logo to
static/img
- point to this using Admin Panel
Footer:
- 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:
- The CDN may have faster/closer servers to the client
- Increases the number of files being downloaded simultaneously, since pulled from different hostnames: http://www.websiteoptimization.com/speed/tweak/parallel/
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/000_config.py
:deployment_settings.base.migrate = False deployment_settings.base.prepopulate = False
- Use a CDN for public sites
models/000_config.py
: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/00_db.py
- Bytecode compile the application:
cd /home/web2py python web2py.py -S eden -M -R applications/eden/static/scripts/tools/compile.py
- Use MySQL or PostgreSQL instead of SQLite
- Create Indexes on commonly-accessed tables
- Use YSlow Firefox plugin to analyse the site
- Ensure images are optimised: http://tools.dynamicdrive.com/imageoptimizer/index.php
- DeveloperGuidelinesOptimisation#JavaScript
- Compress JavaScript: http://compressorrater.thruhere.net
- Use Slimmer on HTML/CSS?
- GZip static files in Apache: http://developer.yahoo.com/performance/rules.html#gzip
- Set Expires on static files in Apache
- Enable caching
- return response.render('customview.html', data=data): http://groups.google.com/group/web2py/msg/39210d40d8a729c0
- http://groups.google.co.uk/group/web2py/browse_thread/thread/218bb58c96883578
- Clustering with Pound: http://www.web2pyslices.com/main/slices/take_slice/33 (Discussion)
- Add Squid in front of Apache for caching?
- HAProxy, etc: http://www.slideshare.net/zeeg/djangocon-2010-scaling-disqus
Static Home Page
In order to improve performance & scalability, you may wish to set a page (usually the homepage) as static. To do this:
- Visit the page in a browser & Save to /static/index.html
- Edit the page to remove anything unnecessary (e.g. Ext)
- Adjust paths to ../ instead of /eden/ if you wish the app to remain portable
- include the Language selector dropdown, if-used
- Configure the Web server to redirect to this static page for unregistered users:
- Remember to maintain this page if you make changes to the main page!
