Unique Case ID

[chavene]

Feature name: Unique case ID
Deadline: Not defined
General goal: To allow data collectors/respondents fill in data only once (without repetition) from respondents provided with unique IDs
Example use cases: An example of application that has unique ID features is CS-Pro

Is this possible?

@DJAA, maybe this post discussed previously should be helpful:

Get consecutive id number in form before submission (or in offline mode)

Hi @wodbow, if you are going to be collecting data from a single device, you can increment an ID using the last-saved feature as follows: survey type name label default integer id Client ID if(${last-saved#id} = ‘’, 1, ${last-saved#id} + 1) text name What is your name? Note that this will not increment the ID across multiple devices. This feature is also not yet available on the OCHA server until Enketo is upgrade next week:

But please note that this only works at the enumerators level.

Can i use last ID to compare it with the current ID so that I can create a constraint message if the last ID equal to the current ID I can get the message saying that the ID have been given suppose that I have a string IDs like (eg: 13-KG-33)

Briefly, I want to inform enumerator that he/she entered the same IDs for the last case to the current case

@DJAA, maybe you will first need to have an understanding of the last-saved function. Maybe you could go through this document for better understanding. It only brings back the value that was stored in the variable.

If you follow the post shared above it has a small expression added to the function that automatically increases the value (while trying to collect the record for the next form). Hence, you should not need any constraints to check if the information recorded in the previous form is the same for the current form.

Good,
I am also asking myself if kobo can use the function text to generate number starting by zero. for example in excel we generate this value 001 by using text(A2,“000”). can I generate this number from kobo?.

Thank you!

[DJAA]

I mean something like this text(${x},“000”) in calculation column

[DJAA]

Can you support me to create this number(0001,0052,1000, etc…) if it is possible just like what this function does in excel. text(${x},“000”) ??

Good morning ,

I would like to suggest unique case ID within the device not the server side to prevent an enumerator to enter a Form twice or more concerning the same subject.

I implemented such a feature using instance name while entering data with enketo. After data entry , the enumerator saves the Form in draft. If there was already the same instance name, it indicates and the Form can’t be save with that instance name.
This is done After data entry while it would be better to check the instance name AT the beginning of data entry

Thank you
