Configurable Options

These can be set via ​http://127.0.0.1:8000/sahana/admin/setting/update/1

• Admin Name/Email/Tel
• Debug: improve performance by deselecting this option.
• Self-Registration: disable Self-Registration by deselecting this option.
• Audit Read: Enable Auditing of all Read operations (Display)
• Audit Write: Enable Auditing of all Write operations (Create/Update/Delete)

In time these will be configured by Web Setup.

Some Auth options are currently only configurable via editing {{models/00_db.py}}:

mail.settings.server
mail.sender
auth.settings.login_methods.append(ldap_auth())
auth.settings.registration_requires_verification
auth.settings.captcha
auth.messages.verify_email
auth.settings.registration_requires_approval
auth.settings.gmail_login

In time we could expose to a Web-based admin page, although it's low priority as these are mostly installation-time decisions.

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
table = 'pr_person'
db[table].pr_pe_label.readable = False
db[table].pr_pe_label.writable = False
db[table].local_name.readable = False
db[table].local_name.writable = False
db[table].opt_pr_gender.readable = False
db[table].opt_pr_gender.writable = False
db[table].opt_pr_age_group.readable = False
db[table].opt_pr_age_group.writable = False
db[table].email.readable = False
db[table].email.writable = False
db[table].mobile_phone.readable = False
db[table].mobile_phone.writable = False
db[table].date_of_birth.readable = False
db[table].date_of_birth.writable = False
db[table].opt_pr_nationality.readable = False
db[table].opt_pr_nationality.writable = False
db[table].opt_pr_country.readable = False
db[table].opt_pr_country.writable = False
db[table].opt_pr_religion.readable = False
db[table].opt_pr_religion.writable = False
db[table].opt_pr_marital_status.readable = False
db[table].opt_pr_marital_status.writable = False
db[table].occupation.readable = False
db[table].occupation.writable = False

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 'Read' access to all records.

To Edit records, users need to be added to the 'Editors' role.

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

Security policy is configured in models/zzz.py

favicon.ico & robots.txt

These can be provided via 2 different means:

• mod_rewrite
• web2py/routes.py: copy routes.example.py & edit

loadingAnimation.gif

This thickbox file needs a hardcoded full path (relative paths don't work), so if you rename your app to something other than 'sahana' then you should amend

• static/scripts/S3/thickbox.js
• static/scripts/S3/thickbox.min.js
• static/scripts/S3/thickbox.compressed.js

Themes

Ensure these files are writable by the webserver:

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

• copy new footer to views/
• point to this using Admin Panel

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

• Use ​YSlow Firefox plugin to analyse the site
• Ensure images are optimised: ​http://tools.dynamicdrive.com/imageoptimizer/index.php
• 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
• Use MySQL or PostgreSQL instead of SQLite
• Disable DB migrations in 00_db.py: migrate = False
• Bytecode compile the application
• 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
