Total size of a document array

 local!docSizeList: if(
      rule!APN_isEmpty(
        local!items
      ),
      {},
           apply(
            document(
              _,
              "size"
            ),
           local!items.document
          )
          
    ),

 

I changed the code as above . used the document function . but i am getting some type cast error below 

 

com.appiancorp.suiteapi.common.exceptions.AppianException: The passed parameter(s) are of the wrong type. Received the type Text. (APNX-1-4158-003)

Wrap your document variable in fn!toDocument()

I tried toDocument(local!items.document). but it is still showing error

com.appiancorp.suiteapi.common.exceptions.InvalidDocumentException: Document Does Not Exist or has been Deleted

One problem i noticed is i am trying to pass the document ids which is just added . i think the document id will only get generated once the document is saved

Yes Ramanan, document Id's will be generated only after they get saved in document repository. May b u req to provide more details how you are trying to get the document details? Is it while uploading the document or is it from the documents stored in the repository? This will assist other practictioners in providing a solution to u.

Hi Ashok, It is while uploading documents .. i totally agree with you .. i need to calculate the size of the "item" array within the upload page . is there any way i can achieve this ?

Hey Ramanan, if ur env is 17.2 and above version, then a!fileUpload() function allows you to access the metadata directly. Please refer to the link below:
docs.appian.com/.../File_Upload_Component.html
If ur env is below 17.2 then u might req to tweek a bit. Let us know which Appian version is ur environment in

It is possible to use the fileUploadField to gather certain properties of just-uploaded files, though I would note that this is officially unsupported functionality and therefore might change between Appian versions with no warning or explanation.  I also need to note that you're apparently using the 17.1 version of a!fileUploadField, which accesses only an abbreviated text version of the file size, i.e. "2kb" or "2MB".  In later versions it's possible to get the file size in bytes from each uploaded file.

If you want to proceed with the unsupported functionality, I have found some success using the following expression rule which I developed (for versions >=17.3)

/* GLBL_getTempUploadedFileProperties */
/* by: mike schmitt */
if(
 rule!APN_isBlank(ri!document),
 
 {
   fullName: null(),
   name: null(),
   ext: null(),
   size: tointeger(null())
 },

 with(
   
   local!value: a!fileUploadField(value: ri!document, fileNames: fv!file),

   local!fileDetails: tostring(local!value.contents.value.filename),
   
   local!fileName: extract(local!fileDetails, "[name=", ", extension" )[1],
   local!fileExt: extract(local!fileDetails, "extension=", ", size")[1],
   local!fileSize: tointeger(extract(local!fileDetails, "size=", "]")[1]),
   {
     fullName: local!fileName & if(rule!APN_isBlank(local!fileExt), "", "." & local!fileExt),
     name: local!fileName,
     ext: local!fileExt,
     size: local!fileSize
   }
 )
)

This rule returns a dictionary consisting of fullName (name & extension), name, extension, and size (bytes).  I highly suggest that if you use functionality like this, you at least keep it compartmentalized in as few places as possible (like one expression rule) so that if/when future updates change the way things work, the rule can be adjusted as needed or deprecated if Appian ever sees fit to allow us to do this via supported functionality (such as allowing us to access the fv! properties in the saveInto parameter of the a!fileUploadField, hint hint).

Please let me know if you have any questions.

Thanks Mike . I will try this out
