Using Multer Upload Files From Two Fields of Separate Forms on Different Pages

Using Multer Upload Files From Two Fields of Separate Forms on Different Pages

In this example I have two fields - resume and image. Resume in one form and Image in other. Both are on separate pages.

First import dependencies
const path = require('path'); // for getting file extension
const multer = require('multer'); // for uploading files
const uuidv4 = require('uuidv4'); // for naming files with random characters

Define fileStorage and fileFilter
const fileStorage = multer.diskStorage({
destination: (req, file, cb) => { // setting destination of where the file to be stored
if (file.fieldname === "resume") { // if uploading resume
cb(null, 'resumes');
} else { // else uploading image
cb(null, 'images');
}
},
filename: (req, file, cb) => { // naming file
cb(null, file.fieldname+"-"+uuidv4()+path.extname(file.originalname));
}
});

const fileFilter = (req, file, cb) => {
if (file.fieldname === "resume") { // if uploading resume
if (
file.mimetype === 'application/pdf' ||
file.mimetype === 'application/msword' ||
file.mimetype === 'application/vnd.openxmlformats-officedocument.wordprocessingml.document'
) { // check file type to be pdf, doc, or docx
cb(null, true);
} else {
cb(null, false); // else fails
}
} else { // else uploading image
if (
file.mimetype === 'image/png' ||
file.mimetype === 'image/jpg' ||
file.mimetype === 'image/jpeg'
) { // check file type to be png, jpeg, or jpg
cb(null, true);
} else {
cb(null, false); // else fails
}
}
};
Middleware for multer
app.use(
multer(
{
storage: fileStorage,
limits:
{
fileSize:'2mb'
},
fileFilter: fileFilter
}
).fields(
[
{
name: 'resume',
maxCount: 1
},
{
name: 'image',
maxCount: 1
}
]
)
);
And then call your routes. You may need to add csrf protection or authentication along with this for security. But this should work fine.

Python - List - Append, Count, Extend, Index, Insert, Pop, Remove, Reverse, Sort

🐍 Advance List List is widely used and it's functionalities are heavily useful. Append Adds one element at the end of the list. Syntax list1.append(value) Input l1 = [1, 2, 3] l1.append(4) l1 Output [1, 2, 3, 4] append can be used to add any datatype in a list. It can even add list inside list. Caution: Append does not return anything. It just appends the list. Count .count(value) counts the number of occurrences of an element in the list. Syntax list1.count(value) Input l1 = [1, 2, 3, 4, 3] l1.count(3) Output 2 It returns 0 if the value is not found in the list. Extend .count(value) counts the number of occurrences of an element in the list. Syntax list1.extend(list) Input l1 = [1, 2, 3] l1.extend([4, 5]) Output [1, 2, 3, 4, 5] If we use append, entire list will be added to the first list like one element. Extend, i nstead of considering a list as one element, it joins the two lists one after other. Append works in the following way. Input l1 = [1, 2, 3] l1.append([4, 5]) Output...

Difference between .exec() and .execPopulate() in Mongoose?

Here I answer what is the difference between .exec() and .execPopulate() in Mongoose? .exec() is used with a query while .execPopulate() is used with a document Syntax for .exec() is as follows: Model.query() . populate ( 'field' ) . exec () // returns promise . then ( function ( document ) { console . log ( document ); }); Syntax for .execPopulate() is as follows: fetchedDocument . populate ( 'field' ) . execPopulate () // returns promise . then ( function ( document ) { console . log ( document ); }); When working with individual document use .execPopulate(), for model query use .exec(). Both returns a promise. One can do without .exec() or .execPopulate() but then has to pass a callback in populate.
