Apply skip logic to items in a select list

Users
1

We are currently using a select list to help schedule future visits, where
the list items include "tomorrow", "in one week", etc. Ideally, we would
like to reduce the number of available items based on the EDD...to force
the next prenatal visit to be scheduled before the EDD. While I'm pretty
sure that Vellum/CC 1.3 does not (yet) support applying skip logic to
individual items, I seem to remember talk about this being possible in the
future.

So, my question is: is it possible to dynamically reduce (or increase)
the items in a select list using "custom" xform xml?

Thanks, Ray

Ray,

This is fairly straightforward with itemsets and
predicate expressions CommCare 2.0 (although we don't yet support them in
Vellum, you'd need to write a custom xform), but it's not particularly easy
in CommCare 1.3.

You can see an example (although more complex than what you need) itemsets
in commcare 1.3 at

https://bitbucket.org/commcare/commcare-apps/src/2aa2ad268ded/commcare-fp/fp_form.xml

Search for itemset to see the xml constructs. The basic idea is to use a
repeated structure for the itemset, but to reference the nodes with a
single (somewhat awkward) bind. In 2.0 you would accomplish this in a
similar way, but using predicate expressions to define the relevancy
conditions one at a time.

Clayton,

Now that we are starting to look at 2.0, I would like to customize our
select item lists. Could you point me to a CC 2.0 example of how to
accomplish this?

Our specific use case: when presenting the CHW with options for the the
next scheduled postpartum visit date, eliminate items that are more than 40
days after the actual delivery date (e.g. drop the 'in 3 weeks" option if
the delivery occurred 2 weeks ago)

Thanks, Ray

Ray,

This is accomplished in a very similar manner to the 1.3 form I sent, but
in a much more straightforward way.

I whipped up a quick guide at

Hi Clayton -- I haven't been able to get this example working. I'm trying
to have enumerators pick a Province and then a District. I'd like to hide
certain district options based on the choice of Province. Here's the form
I'm using:
https://github.com/Aquaya/SDSMAS/blob/master/sdsmas-water-quality-xform.xml

When I upload this to a test phone and pick a Province, I still see all of
the District options. I'm on CommCare 2.0. Any ideas?

Matt,

I'll look over this form and let you know, but I also should tell you that
there's a much simpler way to structure the form you've set up here. you
could instead try

.... ...

...

<select1 ref="/data/selectedprovince">
  <label ref="jr:itext('province-label')" />
  <itemset nodeset="/data/provinces/province">
    <label ref="jr:itext(@id)" />
    <value ref="@id" />
  </itemset>
</select1>

<select1 ref="/data/selecteddistrict">
  <label ref="jr:itext('district-label')" />
  <itemset

nodeset="/data/provinces/province[@id=/data/selectedprovince]/district">



This design allows you to get around any issues you're having with the
current setup, and is a lot cleaner (you don't need a bind for every
district). Future districts/provinces can be added purely to the instance
model and to the itext.

Thanks a lot Clayton, I've been testing this structure today and it's far
better. Appreciate the help!
