[quote userid="91720" url="~/discussions/f/rules/35062/how-to-pass-array-in-expression-rule/135855"]Instead of [ ] , I need { } [/quote]

The [ ] here are because the structure of your code indicates that the "CAC" property will contain an array, since you use curly brackets and then a!map(). If it's just supposed to contain a single sub-dictionary then you don't need to double-indicate this - meaning you could just pass in an a!map() call, OR the curly brackets - when you use both, it assumes that the property contains an array of (one of) that map.

This is what I get when I comment out just one of those:

a!toJson(
{
name: "NAME",
Comment: "comments",
CAC: {
a!map(
TypeId: 1,
addcolleague: a!map(
email: "requestorEmail",
displayname:"requestorName",

deletedFlag: false,
identityProviderID: 2,
idFromProvider:"Value"

)

)
}
}
)

I'm getting output as

"{"name":"NAME",
Comment":"comments",

"CAC:
[

{"TypeId":1,
"addcolleague":{"email":"requestorEmail",
"displayname":"requestorName",
deletedFlag":false,
"identityProviderID":2,

"idFromProvider":"sagdoi"

}}

]

}"

Mike Schmitt :Instead of [ ] , I need { } ,can you please help ,rest everything is expected.

I'm passing this expressinrule output as an input to integration ,it says [ ] is invalid. can you please help

I don't recommend ever using nested CDTs, personally.

Mike Schmitt :

I have one table in DB and created a CDT created from the same . In the CDT I want to add a nested CDT , will it impact db of that table if I add nested cdt in the CDT?

(and of course that entire thing can just be wrapped in a!toJson once you know it's working...)

RE: how to pass array in expression rule

The info you're providing is all super unclear. Please show us:

1) a screenshot of your actual incoming data (making sure we can understand where a CDT is an array of values or not)
2) a screenshot of your actual currently-configured expression rule, which you're trying to run and it isn't working

Just double checking here but do you know how to use a!forEach()? From the context of the code in your original post expression rule screenshot, it looks like you might not. I don't see a single reference to "fv!item" though, so it's making me prety doubtful.

e.g.

a!map(
  name: "some string from DB",
  comment: "some comment",
  
  translatedInputs: a!forEach(
    ri!testInput,
    a!map(
      email: fv!item.inputEmail,
      dName: fv!item.name,
      eFlag: false(),
      isActive: fv!item.activeFlag
    )
  )
)

I want this body as input to an integration .In the existing process model we are passing body only with name and comment as an input to an integration via scriptask (input as expressionrule )

I need to get output of expressionrule as below

a!toJson
({
"name": " some string from db ",
"Comment": "some string from db",

CAC:{
{

      "TypeId": 1, /*Value is always 1*/

add: {
        "email": "some string from data ",
        "dName" : "some string from data",
"Provider" : "some string from data",

        "eFlag": false,
        "dFlag": false,
        "ID": 2

      }
    }
}
})

name ,comment,email,provider and dname values are present in one CDT . I'm trying build an array structure and get email and dname from main CDT where existing values are present.

1. Have already existing CDT I..e Main CDT ---name ,comment,email,dname and few other fields and now i have added CAC Cdt in this mail CDT as an array

2. Created One CDT for CAC with fields type ID and add CDT

3. In ADD CDT , added fields email,name,provider,eflag ,dflag

Can you please help because of incorrect looping server got crashes due to memoryheap

Is the code you shared your actual code? This will hardly work.

In line 3, why do you wrap ri!name in quotes?

In line 7, why do you wrap the field name in quotes?

In line 13, what is "fvfv!ite!item.requestorname"?

And I have the same question as Mike Schmitt has. What is the input, and what is the intended output?

I have updated the above comment with required details

Mike Schmitt :can you please look at this

RE: how to pass array in expression rule

Mike Schmitt — Thu, 23 May 2024 18:45:16 GMT

It's still pretty unclear what your actual inputs will be and what your desired output is. Could you perhaps simplify somewhat and re-try?

In your screenshot, "ri!add" is not configured as an array (list), despite that being specifically what Stefan advised.

Dictionaries are lists of field-value pairs. In that line with the foreach, I am missing a field name.

I would expect something like this:

fieldName: a!forEach(

You can add a rule input of that M_addcollegue type and make it a list.
