How do i replace a file in uploads but keep the path.

[chrisAlwinYS]

Hi all,

Im trying to either replace a file and keep the same URL path or use a "slug" field to set the path of the specific document. It would be best I think to allow a "slug" field. However, I understand that it's not a simple just map the path. So replacing the file is probably the best option, but it keeps adding "-n" to the file name so I have to upload twice to get the name.

I have tried many hooks, i they keep coming up short.

What I'm after is, to upload the file pdf-important.pdf, the URL is created and linked to. When version two is created the file uploaded is pdf-important-v2.pdf is sent but the original URL is kept so any previous links are not lost.

Thanks, in advance

If anyone comes across this and needs help, I have solved my issue using the beforeOperation and afterChange hooks. This is using a title field to generate the "slug" but it stays consistent. There's a possibility to make this a plugin to add to other documents should we need to...

    beforeOperation: [
      async ({ args, operation, req }) => {
        if (operation === 'create' || operation === 'update') {
          if (req?.file && args?.data?.title) {
            const files = req?.file
            if (files && files && files.name) {
              const fileExtension = files.name.split('.').pop() // Extract file extension
              const fileTitle = args?.data?.title.replace(/[^a-z0-9.]/gi, '').toLowerCase()
              const newFileName = `${fileTitle}.${fileExtension}`
              files.name = newFileName // Assign the new name
            }
          }
        }
        return args
      },
    ],
    afterChange: [
      async ({ context, req, doc }) => {
        const { payload } = req
        // if the result file.name does not match the updated one then run this update
        if (req.file && doc?.filename && doc.filename !== req.file.name) {
          // return if flag was previously set
          if (context.triggerAfterChange === false) {
            return
          }
          await payload.update({
            collection: 'documents',
            id: doc.id,
            data: { ...doc.data },
            file: {
              data: req.file?.data,
              mimetype: req.file?.mimetype,
              name: req.file?.name,
              size: req.file?.size,
            } as File,
            context: {
              // set a flag to prevent from running again
              triggerAfterChange: false,
            }
          })
        }
        return {...doc, filename: req.file?.name}
      },
    ],
  },
