Dataweave - Replace value of a field in an object


I have a Java Object as input payload:

{
"name"="Michael",
"surname"="Alpha",
"mail"="demo@gmail.com",
"gender"="Male"
}

I want change the gender value keeping the rest of the message:

%dw 2.0
output application/java
---
gender: if(payload.gender == "Male") "" else payload.gender

But it return only the gender field. How can I solve that?


Solution

  • The dataweave script needs to match your output structure and you are only outputting a single gender field.

    One quick way yo just modify the current payload is using payload ++.

    If your payload is a map/object it will just replace the key if it exists or adds it if not. Example:

    %dw 2.0
    output application/java
    ---
    payload ++ {gender: (if (payload.gender == "male") ""  else payload.gender)}
