Saving Multiple Page Survey Answers as a JSON Object

At a high level I'm only referring to code you've already pasted previously in this post not within code boxes.

As per your issue: I looked through the code briefly and as of yet I don't have any specific suggestions other than my normal advice, which is, start with a simple-but-working version, and add complexity one step at a time making sure each addition still works.

If you'd be willing to edit your original post to include the same code you posted originally, but moved into a code box and with restored indentation, I'll try to take a closer look. (Restoring indentation should be as easy as opening a blank Expression Rule editor and pasting the code there, then re-copying the result). As an aside: when posting Appian Expression/SAIL code I often select the "JAVA" language option in the Code Box settings as it adds context highlighting that seems generally compatible with Appian code (though I do wish they'd add an Appian-specific option...)

I have more than 2000 lines of code so could you please let me know which part would you like me to copy here?

To clarify, if you copy/paste indented code straight from Appian into a code box, indentation will be preserved as well.

Hi Mike! Thank you for your response! I am adding here the same code i added above to save the value for each response.

a!forEach(
items: local!questions,
expression: {
/*the start of the questions types*/
if(
fv!item.responsetype = "text",
a!textField(
value: fv!item.answertext,
saveInto: {
fv!item.answertext,
}
),
)})

Tangentially, this is a **lot** of code to paste into a post in plaintext. You should probably use a Code Box, which makes things like this 100x readable through length limiting, monospaced font, and preservation of indentation/etc.

I already read successfully the json object using those functions as the code below:

local!roots: a!fromJson(
a!jsonPath(
rule!PCEMS_querySurveyJSON(),
"['sections'][*][?(@.sectionparent=='root')]"
)
)

and i am looping on the objects successfully and everything renders fine. the issue here i need to save the user responses for the survey questions in one local variable. i am able to save just each page responses through this code:

a!forEach(
items: local!questions,
expression: {
/*the start of the questions types*/
if(
fv!item.responsetype = "text",
a!textField(
value: fv!item.answertext,
saveInto: {
fv!item.answertext,
}
),
)})

but when i move to another section, this local!questions will be refreshed with the new questions of that subsection page. so i need to have a local variable which has all of the answers and if the user update the value it should be updated in there also.

You can use the sql type TEXT as your column and store the JSON in there. I know you say you're looping through the JSON. I'm not sure what you mean but the simplest way to handle JSON in Appian is to use a map/dictionary for everything and then to use the a!toJSON() and a!fromJSON() functions

Hi Danny,

Thank you for your response! The survey has a hierarchy structure like in the Json above like (children and parents relationship). but any way i already built it by nested loop on the json. but the challenge here how i am going to map all of the answers for all of the subsections of the survey in one place. till now i can map each page answers with a local variable but when i move to another subsection, the local variable will have a new value of the new page questions. I am trying to collect all of the answers in one local variable to save it in a database table as a json object. any thoughts to achieve that?

When you say 'multiple pages' are you referring to a wizard on the same Interface or multiple user inputs tasks? If everything is on the same interface, then you can abstract your dictionary a little more by having a map
a!map(

pageOne: local!jsonOne,

pageTwo: local!jsonTwo

)
