Question

Checking if all documents in a list have the same extension without using forEach()

Hi,

Currently have a rule containing the following where the rule input is a list of documents and constant has text "DOCX"

return true if all document extensions in a list have the extension "DOCX" otherwise return false.

and(
a!forEach(
items: ri!receivedDocumentsList,
expression: document(
fv!item,
"extension"
) = cons!DOCUMENT_EXTENSION_DOCX
)
)

Which works fine but is there a more elegant way to do this?

Hello pauls0008,

Where are you calling this expression rule? What are you looking for exactly? Have you tried creating a separate rule with the validation that you are using and use apply() instead?

Hi,

The rule is to be called from a process model in an xor node. Depending on the boolean value returned to the process model different processing then takes place.

In this first iteration of the rule development a constant is being used but this would be replaced in time by another rule input to allow any extension to be checked.

I had thought of apply() but saw this....

But why handle this in Process model? Have you tried to filter it in the UI and have different saves for the types other that DOCX? Not sure what is the alternate process that you have if the file is not of docx.

a!localVariables(
  local!fileExtensions: {"docx", "DOCX", "PDF"},
  all(exact(_, "DOCX"), upper(local!fileExtensions))
)

I come from a time before a!forEach(), and trust me when I say, it is the "elegant" way.
