Not allow the same question answer twice for the same case

Users
1

Hello all,

I am having difficulty figuring out how to code a form to not allow a user
to enter the same answer for a question. For example, in a repeating group
question, not allow a user to enter in testing information for "Month 1" of
patient treatment twice. Along the same lines, is there a way to prompt or
suggest to the user what month of the patient's treatment it is based on
their previous entry?

Thanks very much
Hannah

Hi Hannah,

To prevent a user from entering the same answer you can specify in the
validation condition that the answer cannot equal the answer from the
previous month. The condition would look something like this; . !=
/data/month_1_answer

To prompt or suggest to the user what month it is you can simply use a
label that displays a hidden value of the month incremented by the previous
visit.

Hope this is helpful!

Hi Ameera,

Thank you so much for your response. The validation condition you suggested
is not working, I think because of the way my question is formatted. I have
the question as part of a repeating group. The question ID is "Month_X" and
label is "Month of patient's treatment:" with an integer answer format.
Since the user can enter 1-25 or higher as the month of treatment, I don't
know that your recommendation would work in that scenario.

Again, I really appreciate your help.

Take care,
Hannah

Hi Hannah,

The overall strategy that you want to employ here is to create a list of
the months that have already been used and check to see if a new day that
is being entered is in that list. Here's one way that I imagine it working:

  1. Create a hidden value that contains a list of numbers that have been
    used. A possible format would be a comma-delimited string of the days
    (,2,4,12,5,...)
  2. Check the string for each number that is being entered. You can use the
    contains() function to see if a number is in the list with a comma on
    either end of it, something like contains(/data/day_of_month_list/, ",num,")
  3. If it passes this check each time through the repeat group, use the
    concat() function to add the new number to the end of the list.
    concat(/data/day_of_month_list/, "num,")

Hi there,

Thank you for your responses. I am having a hard time articulating my
question, I think. Is there a phone number I could call?

I'll also again to explain the function I am looking for in a different
way, so please bear with me one more time. Essentially, I would like to
know how to make answers to a repeating group non-repeatable, including
question in date and integer formats. Perhaps there is a different type of
question that is better fitted for what I want than the repeating group
format?

With your previous suggestion, I do not know how it would work for the
questions I am thinking of because I cannot anticipate what month the user
is inputting data for. For example, for that Bacteriology form I mentioned
previously, I want the user to be able to enter any number between 1 and
25. Say they start with Month 4 of the patient's treatment, so they enter
"4" the first time they input test result data into the form. The next
month, when they add a new group for new test results, I would like them to
no longer be able to enter "4" (to avoid any accidents or data entry
errors), and the month after that no longer be allowed to enter "4" or "5."
I do not think the functions you described would be applicable to this
situation, since the months will vary for each patient.

Does this make more sense?

Thank you again.

Take care,
Hannah

Hi Hannah,
Would it be a reasonable restriction that if someone enters data for month
7, they can no longer enter data for month 6?

Hannah,

I believe Nate's suggestion will work for your case. Let me explain in more
detail:

You'll have your question /data/date_question where your user enters the
month number.

You'll also have some hidden value
https://confluence.dimagi.com/display/commcarepublic/Hidden+Value+Calculations+Tutorial,
say /data/entered_dates that accumulates the dates that have been entered
so far. At first this value will be "" - nothing.

Your date question will have the validation condition not
https://confluence.dimagi.com/display/commcarepublic/CommCare+Functions#CommCareFunctions-not
(contains
https://confluence.dimagi.com/display/commcarepublic/CommCare+Functions#CommCareFunctions-contains(/data/entered_dates,
concat
https://confluence.dimagi.com/display/commcarepublic/CommCare+Functions#CommCareFunctions-concat('-',
/data/date_question, '-')) - this will test whether the answer to
/data/date_question has already been entered. [note the '-'s - I will
explain later]

We'll use case management
https://confluence.dimagi.com/display/commcarepublic/CommCare+Fundamentals+-+Case+Management
to persist the entered_dates between sessions. So, we'll need some
intermediary hidden value called, EG, /data/new_entered_dates.

/data/new_entered_dates will have the calculate condition
'=concat(/data/entered_dates, '-' /data/date_question, '-') [note the '-'s]

Now we'll save /data/new_entered_dates to some case property (for
simplicity, entered_dates)

We'll also load that case property on subsequent form entriers into the
hidden value /data/date_question

So, if we enter '4' the first time, the case property will be saved with
the value '-4-' and if the user tries to enter this again, the validaiton
condition will fail.

This case property will continue to accumulate for subsequent month values.

The reason we use the '-' is because otherwise if we enter date '14' then
later on we will not be able to enter '4' because this is contained within
'14'. The '-' allow us to specify the exact value.

If you only want to enforce that the date number must increase then this is
even easier. We simply save the last entered month value to the case in
some property EG last_date and then enforce that /data/date_question >
/data/last_date, saving /data/date_question to property last_date on
subsequent form entries.

Hope this all makes sense!

Best,
Will
