I'm downloading pdf files using headFULL chromium & puppeteer. I call a javascript function in the browser context and the download starts. The file name comes as is from the server. Issue: Many files I download in a directory are of same names coming from the server and Chrome instead of autosuffixing an index (1) to the file, overwrites the existing one.
Since the file is downloaded by calling a JS function and I have inspected the function as well, I don't have access to a the pdf url. It is triggered using the function call and thus I have no control over the file names.
I have a list of the file names but that in no way helps in changing the filename on the fly, if it it's duplicate name already exists on the machine.
Config: Ubuntu 18.04, Puppeteer 1.18.1
I know either it's a config issue with Nautilus file manager or with Chrome. Is it possible to configure any of these two?
I cannot foresee an option within nodejs where I can rename the file before it's downloaded. A workaround is to download each file in a temp folder, then move it to the required folder while doing a check if it already exists and rename if so. But it adds a lot of time complexity. It would be great to have chrome or nautilus do the task.
Function which triggers the download:
await page.evaluate( (doc_index,arg1,arg2) => openDocument(String(doc_index), String(arg1), String(arg2) ,'ABC','','','XYZ') , doc_index,arg1,arg2 )
Expected behaviour: When the above function is called and pdf starts downloading in the set folder, if a pdf of the same name exists, the new pdf should be renamed to something like pdf_name.pdf(1) or the like.

I uploaded files to LiveResponse library using https://github.com/MicrosoftDocs/microsoft-365-docs/blob/public/microsoft-365/security/defender-endpoint/live-response-library-methods.md API.
I overwrite specific file in mistake (and I have no local backup of this file), How can I recover the content of the file from the LiveResponse library before the overwrite?
When I get the list of the library files using GET /api/libraryfiles I got:
{"#odata.context":"https://api.securitycenter.microsoft.com/api/$metadata#LibraryFiles","value":[{"fileName":"script.ps1","sha256":"8b0....f1c63abad95d6bda","description":"1","creationTime":"2022-08-08T15:45:05.170374Z","lastUpdatedTime":"2022-08-08T15:45:05.170374Z","createdBy":"MyUser","hasParameters":false,"parametersDescription":null}

I am making an image classifier. I have successfully created the folders and I manually placed the .txt files which has links to images from google inside each folder.
I am now trying to download the images from each .txt file either into a folder inside each folder category, or into each category folder that also has the .txt file, however i keep getting errors. please help.
I manually placed the .txt files in each of the folders as they was in the parent folder name as PLANTS but this has not made a difference.
I expected to get all the images downloaded in their respective folders from the .txt files with google image links but it is not working, whether the .txt is inside the main PLANTS FOLDER or inside each category folder which is inside the PLANTS folder
instead i get the below errors
FileNotFoundError
please see attached screen shot

Long filenames or paths with spaces are supported by NTFS in Windows NT. However, these filenames or directory names require quotation marks around them when they are specified in a command prompt operation. Failure to use the quotation marks results in the error message.
for i in range(len(folders)):
path = "content/gdrive/My Drive/Colab Notebooks/Flowers/PLANTS"
#for creating directory we need path class object so below this:
dest_for_creating_directory = path/folders[i]
#for searchi directory which have spaces we need doubleQuotations that
#why user below one in download image function instead of dest.
dest_for_searching_directory = path+"/"+folders[i]
Note: its better practice to write folder/file name without space more info
When i want to add an attachement(csv) to a file using the addon nuxeo csv import. I got this issue:
Line 2 ERROR The file NuxeoCSV-USERDOC.pdf does not exist
This is the csv file :
name,"type","dc:title","dc:description","file:content","dc:nature","dc:source"
nuxeo-csv-userdoc,"File","Nuxeo CSV User documentation","This is the user guide for Nuxeo CSV","NuxeoCSV-USERDOC.pdf","procedure","http://doc.nuxeo.com"
Nuxeo-csv-sample-3,"File","Nuxeo CSV Sample","This a second file imported with Nuxeo CSV","Nuxeo-csv-sample-3.odt","article","http://doc.nuxeo.com"
It's demanded to make some changes in the file conf but I don't get the last line. How I'm supposed to add the path and how can I add nuxeo.csv.blobs.folder, just by pasting it?
Configuration :
The Nuxeo CSV addon enables users to create file documents and upload their
main attachment at the same time. This requires to configure where the
server will take the attachments. This is done adding the parameter
nuxeo.csv.blobs.folder in the server nuxeo.conf and giving it a value that
is a local path to a folder that can be accessed by the server.
Thanks in advance.
I have been using Carrierwave for file uploads for some time. I did not try to rename the files as they got uploaded. Now I want to give each file a random name and a file extension that's consistent with the content type. I read the wiki and other sites, and it was recommended that in the uploader, I could:
def filename
"#{secure_token}.#{file.extension}" if original_filename.present?
end
private
def secure_token
#implement the secure token
end
It worked fine on files uploaded after these additions to the uploader. But I got many files that were uploaded before this change. I was wondering if someone could tell me how to migrate the old files.
I tried adding a method to the uploader:
def rename_file!
model.update_attribute mounted_as, "#{secure_token}.#{file.extension}"
recreate_versions!
end
then in the rails console, I tried calling this on an model with attachment. However, I found that the mounted_as column of the model never got updated, though on the file system, various versions of the file were created with the new name. When I inspected the mounted_as field of the model, it did not get updated. The log actually said the column was updated with the old value.
How can I get the mounted_as column on the model updated?
In addition, it seemed like the old files with the old names were still on the file system. Is there a way to remove them? I tried adding a line:
file.move_to File.join("#{File.dirname file.path}, "#{secure_token}.#{file.extension}")
in the rename_file! method. It renamed the files, but did not update the mounted_as column on the model. So accessing its URL resulted in a 404.
I know this is a little old now, but perhaps useful for others.
After updating your Uploader with the filename method, like you have, you could run this from the Rails console;
Post.all.each do |p|
p.avatar.recreate_versions!
p.save!
end
In the current version of CarrierWave, this will both rename the file and update the model record.
Post of course is the model name and avatar the column on which you are mounting the uploader, so change those as required.
I have a serious issue.
I am using excel object for opening the excel file
it works fine i my PC.
when i make application as a website and running the page and uploading it gives the error "'C:\Documents and Settings\Administrator\Desktop\Work\SABRE MSO Mapping Request Template.xlsx' could not be found. Check the spelling of the file name, and verify that the file location is correct. If you are trying to open the file from your list of most recently used files, make sure that the file has not been renamed, moved, or deleted. ".
I think it taking server path...but i want to open client excel file before saving the file to the server.
Plz help.
have you tried server.mappath() method ?? Do you have proper permissions setup to access the folder??
Are you passing complete file path to the excel for opening the file? Please try this:
if (fileUpload.HasFile)
{
string fileName = "PATH_RELATIVE_TO_YOUR_SITE" + "FILE_NAME";
fileUpload.PostedFile.SaveAs(fileName);
//NOW open excel using fileName;
}
also you need write permissions to the path (folder) you are writing file to.
