NetSuite SuiteScript to modify file in the file cabinet - netsuite

Question

We have files within the NetSuite file cabient which need to be updated (the url field has changed). I found the noted article on this site but there is no code example to perform the requested. It indicates to use the nlapiLoadFile and nlapiSubmitFile calls; would anyone be able to assist with a code example?

Can Netsuite Suitescript modify a file in the file cabinet?

Answer 1

Ya, it seems a bit odd. The only way I found is:
Load The File
Create a file handle with:
Set the file name to one that you intended.
Set the content to intended one
Set the folder and submit.
I have attached a code snippet
var file = nlapiLoadFile(file_id);
var content = file.getValue();
content = '...put your content...';
file = nlapiCreateFile(file.getName(), 'FILE TYPE', content);
file.setFolder(required_folder_id);
nlapiSubmitFile(file);
Hope this helps.

There is no special API function to edit an existing file, you could take the details of the existing file and create a new file with the same details but changing the data field only and deleting the old file.
var start = function(request, response)
{
var fileId = "107524";//get the existing file id
var file = nlapiLoadFile(fileId);
var data = file.getValue();
var name = file.getName();
var folderId = file.getFolder();
var fileType = file.getType();
nlapiDeleteFile(fileId);//delete the older file
data += ",this is the appended data";//change the data
var newFile = nlapiCreateFile(name, fileType, data);//create a new file with the same details
newFile.setFolder(folderId);
nlapiSubmitFile(newFile);//submit it
}

Do you mean file instead of field? If you use nlapiLoadFile(/path/file), you can then use getURL() to provide a link to that file.

NetSuite does not have a edit file kind of an API. You will have to load the original file, modify the contents as per your needs and then submit that data by creating a new file with same file name and inside the same folder. This simply overrides the existing file.
Here's the code sample:
var original = nlapiLoadFile(FILE_ID_OR_FILE_PATH_IN_FILE_CABINET);
var originalContent = original.getValue(); //Return the value (base64 encoded for binary types) of the file
var updated = nlapiCreateFile(original.getName(), FILE_TYPE, UPDATED_FILE_CONTENTS);
updated.setFolder(original.getFolder());
nlapiSubmitFile(updated);

I experienced a similar error when trying to modify a file using SuiteScript in Netsuite at the server-side. I was using the way explained in the documentation, where they say copying a new file through file.copy() with conflictResolution: file.ConflictResolution.OVERWRITE. However, that way didn't work for me as it neither created the file nor overwrote it. Finally, I use the following form to get it working:
...
let fileNew = file.create({
name: 'same_name_of_the_original_file',
fileType: file.Type.PLAINTEXT, // change it depending the file type you will create
contents: credentials.body,
});
fileNew.folder = folder_id;
let fileId = fileNew.save();
...
So, the key is to change the folder and saving it after the file is created. After that, saving the file would overwrite the original.
