file.info does not work in r shiny?

#1

Hi,

I want to capture the creation date of file I am uploading in r shiny.
It works on local machine but when I deploy on r shiny it does not work. It gives NA for all file.info details.
file.info works only for local machine ? is there any way I can capture the creation date?
following is the log of r shiny

How are you uploading the file ?
It is possible that it is not name as you expect... :thinking:

Yes I am uploading file to shiny and also changing the name of jpg file, I want to display the jpg file for each outlet so I am hard coding it
inFile <- input$myFile
if (is.null(inFile))
return()
inFile$name <- paste(input$time,input$attoutlet,Sys.Date(), ".jpg", sep="")
print(inFile$name)
file.copy(inFile$datapath, file.path(".", inFile$name), recursive = TRUE )

This is how I am using new file name for rendering
output$HubtowSolaris1 <- renderImage({
filename <- "Star Bazaar Hubtown Solaris.jpg"
list(src = filename,
width = 300,
height = 200,
alt = paste("Image number", input$n))
}, deleteFile = FALSE)

If I may, it is really difficult to help you without any reproducible example.

Can you try to build something up ?
