node cannot read property of undefined
Question
I'm making api for foodtruck for practice I added
geometry: {
type: { default: 'Point' },
coordinates: [ Number ]
}
geometry in the foodtruck model and I added
api.post('/add', (req, res) => {
let newFoodTruck = new FoodTruck()
newFoodTruck.name = req.body.name
newFoodTruck.foodtype = req.body.foodtype
newFoodTruck.avgcost = req.body.avgcost
newFoodTruck.geometry.coordinates = req.body.geometry.coordinates
newFoodTruck.save(err => {
if (err) {
res.send(err)
}
res.json({ message: req.body.name+' FoodTruck saved successfully' })
})
})
geometry in the post to get the coordinates data from users when they request but, when I tried to add the data like (POST) http://localhost:3005/v1/foodtruck/add
{
"name": "Hot dog",
"foodtype": "Meet",
"evgcost": 5.99,
"geometry": {
"coordinates": [35, 34]
}
}
it returns

I'm still confusing why it returns coordinates of undefined

It was because of the type
geometry: {
type: { type: String, default: 'Point' },
coordinates: [ Number ]
},
I missed type: String in geometry but, I don't know why needed type for geometry because I only needed coordinates Number
