javascript - Find out number of files being uploaded with Node before upload -


i'm using node.js , multer upload files. post angular , files sent in body (when @ post request through developer tools see files sent part of request payload).

now i'm introducing paywall app limiting upload of files 3 per month. need complex check see, depending on account, how many files can upload.

the multer api poor handling sort of scenario. need check how many files in request before goes through multer upload. thought must surely available in request, somehow it's not (it within multer).

before multer, req.body {} , req.files undefined. however, when inside multer e.g. 

var upload = multer({ //multer settings     storage: storage }).any();   upload(req, res, function(err, x) {      // req.files contains files can find number req.files.length     ...

so, how can check how many files in request, without having them going through multer - means uploaded, if user has reached limit, i'll have delete?

transpose - Maple isnt executing function but prints function term -

im using maple im in worksheetmode tried using maple input , 2d input , want transpose matrix a: := `<|>`(`<,>`(1, .5, -2), `<,>`(.5, 9/4+b, 5+3*b), `<,>`(-2, 5+3*b, 18+9*b+4*a)); b:= transpose(a); when exectute sheet dont translated values, there same input. matrix looks same input matrix plus function term. you can see picture in following link: why arent functions executed? meanwhile b:=a^+ doing right way , transposed matrix. other functions return function body instead needed values... if using 2d input mode (the default) space you've got between transpose , bracketed (b) interpreted multiplcation. rid of such space. also, either load package @ start of document like, with(linearalgebra): before calling transpose command package, or call it's full name like, linearalgebra:-transpose(b);
