Code or Examples Relating to DAViCal

Web Display of Calendars

I wrote this to pull calendars from DAViCal to our website. It is a re-write of some classes that pulled data from a Drupal database, so it currently doesn't display all possible text.

I'd love to see this rolled into DAViCal on the user collections page or as a way of displaying groups of collections in read-only mode.

To install, you'll need to update the following line in caldav_display.classes.php with your information, and then adjust the calendars you'd like to display in sample_display.php. Put sample_display.php and calendar.css in a web accessible folder and place the classes file in your path.

$calendar_db = pg_connect("host=hostname port=5432 dbname=rscds user=general password=password_for_general"

Place calendar_notifier on a server with cli php and call it with cron to send out nightly agenda emails. Something like:

0 4 * * * php /usr/local/sbin/calendar/calendar_notifier.php

You'll also need to install Pear's Date class and a relatively recent version of JQuery.

Install davical on a server where you can find an another version of Postgresql

Newly, i have been confronted to install davical on my server, but i had a old version of postgresql (8.0.23) already installed. Unfortunately for me, davical requires a PostgreSQL: 8.1 or greater.

To stay on davical installations rules, i have compiled and installed postgresql 8.4.2 on my system and i have start it on another TCP port ( 5433 ).

For to do this, you can modify file [my new db datastore 8.4.2]/postgresql.conf

 ...
 #------------------------------------------------------------------------------
 # CONNECTIONS AND AUTHENTICATION
 #------------------------------------------------------------------------------
 
 # - Connection Settings -
 
 listen_addresses = '*'          # what IP address(es) to listen on;
                                         # comma-separated list of addresses;
                                         # defaults to 'localhost', '*' = all
                                         # (change requires restart)
 #port = 5432                            # (change requires restart)
 port = 5433                             # (change requires restart)
 max_connections = 100                   # (change requires restart)
 # Note:  Increasing max_connections costs ~400 bytes of shared memory per
 # connection slot, plus lock space (see max_locks_per_transaction).
 ...

After do that, i have modify the create-database.sh file for it be able to found my new instance of postgresql.

I have added some variables :

 PGINSTALL=/opt/postgresql-8.4.2/bin   the path where my new postgresql is
 export PGPORT=5433                    this variable is read by all postgres commands for to know where postgresql server listen

After i modify all lines where i have found a command postgresql in following way :

ex :

 export DBVERSION="`psql -qAt -c "SELECT version();" template1 | cut -f2 -d' ' | cut -f1-2 -d'.'`"
 
 by
 
 export DBVERSION="`${PGINSTALL}/psql -qAt -c "SELECT version();" template1 | cut -f2 -d' ' | cut -f1-2 -d'.'`"

Below the new modified create-database.sh file. Sorry, i have not been able to upload this file on this wiki, perhaps the admin can change that ;-).

 I cannot find a usable database user to construct the DAViCal database with, but
 may have successfully created the davical_app and davical_dba users (I tried :-).
 
 You should edit your pg_hba.conf file to give permissions to the davical_app and
 davical_dba users to access the database and run this script again.  If you still
 continue to see this message then you will need to make sure you run the script
 as a user with full permissions to access the local PostgreSQL database.
 
 If your PostgreSQL database is non-standard then you will need to set the PGHOST,
 PGPORT and/or PGCLUSTER environment variables before running this script again.

I hope this howto can help someone who is in same case ;-)
