This is my model shema:
const DemoSchema = new Schema({
rowOne: {
colOne: {
one: {
name: String,
qty: Number,
},
two: {
name: String,
qty: Number,
},
three: {
name: String,
qty: Number,
},
},
},
rowTwo: {
colOne: {
one: {
name: String,
qty: Number,
},
two: {
name: String,
qty: Number,
},
three: {
name: String,
qty: Number,
},
},
},
});
When I do this it saves data to my model:
const product = await new Regal({
rowOne: { colOne: { two: { name: productName, qty: productQty } } },
});
product.save();
My question is, how can I replace rowOne, colOne and two with user input?
I tried this:
const row = req.body.rows // this must be rowOne or rowTwo
const column = req.body.column // colOne or other (colOne to colNine)
const col = req.body.col // one, two or three
const productName = req.body.name
const productQty = req.body.qty
Attempt 1:
const product = await new Regal({ `${row}`: { `${column}`: { `${col}`: { name: productName, qty: productQty }}}});
'Error --> Property Assignment expected.'
Atempt 2:
const product = await new Regal(`{${row}: { ${column}: { ${col}: { name: ${productName}, qty: ${productQty} } } } }`);
'Error --> Parameter "obj" to Document() must be an object, got {rowOne: { colOne: { one: { name: Milk, količina: 250 } } } }'
You can use variables as keys of objects using square brackets.
let user = 'username';
let newObj = { [user]:'saloni' }
this will create an object like {username:saloni}
. This way you can replace rowOne, colOne, and two with user input by storing them in a variable and then use it.
