We have nested section and want to generate GUID for Section ID when user clicks “Add Item”. Is there way to generate this via scripts? I want to disable this field and let UI auto-generate as GUID.

[Sebastian]

Yes, you could generate this in a script, there is a “guid()” function. So just a loop

for (var item of ctx.data.array.iv) {
   if (!item.UniqueId) {
      item.UniqueId = guid();
   }
}

Where should I put this script out of below? I wanted to generate the moment user clicks “Add item” button.

[Sebastian]

This is not possible. It would be the update and create script which is triggered whenever the content is updated over the API (or UI)

[pankajv82]

let me try to use with create and update script.

@Sebastian I tried for normal field (root field in schema) and it works fine but it does’t work for nested object (my case). I wrote code like below in Update script. can you please check if I am missing anything?

for (var item of ctx.data.Sections.iv) {
if (!item.SectionId) {
item.SectionId = guid();
replace();
}
}

[Sebastian]

You should call “replace()” only once at the end.

[pankajv82]

I have tried that as well but it doesn’t work.

[Sebastian]

What do you mean with: “It does not work”

[pankajv82]

I added one section without SectionID and I saved it but even after saving, I can’t see any value populated in SectionId field.

Updated Code :

for (var item of ctx.data.Sections.iv) {
if (!item.SectionId) {
item.SectionId = guid();
}
}

replace();

[Sebastian]

I have forgotten the problem that the script only detects changes at the root level of contents. Therefore you just have to assign the field to itself:

for (var item of ctx.data.Sections.iv) {
   if (!item.SectionId) {
     item.SectionId = guid();
   }
}
ctx.data.Sections.iv = ctx.data.Sections.iv;

replace();

IMPORTANT: Please use code blocks next time.
