I am not able to understand that what file path its talking about, it's sound stupid but i even changed the name and id of file section. X--

CodePudding user response:

Instead of:

const newUpload = new Uploaddb({
  name: req.body.homename,
  email: req.body.homeemail,
  file: req.body.file,
});

Try it:

const newUpload = new Uploaddb({
  name: req.body.homename,
  email: req.body.homeemail,
  file: req.file.path,
});

CodePudding user response:

well I still did not understand what was triggering the error but i found the solution instead of file:req.file.file or file:req.file.path it should be file:req.file.filename because what i need to transfer to my db is the file name (string) not file (.pdf)

const newUpload = new Uploaddb({
  name: req.body.homename,
  email: req.body.homeemail,
  file: req.file.path,
});
