Resource specific values in calendar

patta 2012-03-04 13:18:58 UTC #1

Dear Developers!

Although we’re running an eGroupware installation in our office for
several years, I’m quite new to eGroupware development. Thus, I’d be
very happy to receive any links to informations about egroupware
development or tutorials.

My question is whether there is a way to obtain additional fields when
booking a resource in the calendar, specific to the selected resource.

My resources are devices for scientific experiments, and if such a
device is bookes, additional information is required regarding the
experiment. (Maybe more common, one could imagine a room as the resource
and the number of chairs required as the additional information).

So far, we use custom fields in the calendar as a quick and dirty
solution, but there are various drawbacks.

Would such an development be a new application? Or is there any source
of explanation of how to change the existing code to add my
functionality?

Regards and thanks in advance,

Patrick

Custom fields are for that purpose. Most likely your solution will
involve them in some way, but how you go about it will depend on what
you perceive as the drawbacks, and what functionality you want to add.
If resources + calendar provide almost a solution, you probably don’t
want to create a new application. Where and how you change the code
depends on what you want to do.

Hello!

So far, we use custom fields in the calendar as a quick and dirty
solution, but there are various drawbacks.

Custom fields are for that purpose. Most likely your solution will
involve them in some way, but how you go about it will depend on what
you perceive as the drawbacks, and what functionality you want to add.

First of all, we have different resources that require different
information. If we use custom fields as implemented, all customn fields
are listed in the “Custom fields” tab, but - depending on the booked
resource - only a few of them are required. Furthermore, you can even
enter these custom information if you simply add an appointment to your
calendar and do not book any resource.

Second drawback is that these information are not listed in the resource
calendar, but I think that could be tweaked quite easily.

We have a set of roughly ten resources all of which require ten or more
fields of additional information. That makes a hundred custom fields and
it is not very user-friendly if you have to search in a hundred fields
which ones are required.

If resources + calendar provide almost a solution, you probably don’t
want to create a new application. Where and how you change the code
depends on what you want to do.

I agree that custom fields and calendar can do the job, but I need to
hook into the code a bit, I guess. Is there any documentation how to do
that, which hooks exists, for example? I’d like to avoid that an update
of eGroupware destroys all the customization…

Patrick

This may not work, but my first attempt would be to customize the
calendar edit etemplate (calendar.edit) with an additional tab that
contains a custom field widget for each resource’s custom fields.
Make sure to change the template or bump the version. You can limit
the fields shown in each custom field widget with the option (from
etemplate/inc/class.customfields_widget.inc.php):
,[field_name[,field_name]+]
Then in class.calendar_uiforms.inc.php, edit(), check to see if your
resource is a participant and turn on the appropriate cf widget
accordingly using the Grid row - disabled attribute and an entry in
the $content array.

I don’t know of any relevant hooks you could use, but for the most
part this seems to be an interface customization. If you export your
template changes to a XML file, and keep a diff of your code changes,
you should be OK.
