how to handle multiple request keys with the same value? - node.js

Question

For this project, I'm building out models and passing in values from the body of a POST request. I want to understand how I should be declaring the models.
Sample of JSON which I want to be posted to MongoDB.
{
"signageId": "5cd857c4965f863b7c88d24a",
"parameters": {
"imageURL": "url.com",
"page": {
"pageHeight": "100", //want to change to "height"
"pageWidth": "100" //want to change to "width"
},
"density": {
"height": "300",
"width": "300"
}
}
}
I want to name pageHeight and pageWidth just "height" and "width" within the JSON, like I have done for the density segment, but I'm having difficulties knowing how to declare the models and grab the values from the request.
Model I'm using:
const ObjectSchema = new Schema({
signageId: {
type: String,
require: true
}
parameters: {
imageURL: {
type: String,
require: true
}
},
page: {
pageHeight: {
type: String
},
pageWidth: {
type: String
}
},
density: {
height: {
type: String
},
width: {
type: String
}
}
}
});
Post router
router.post('/', (req, res) =>{
const object = new Objects({
signageId: req.body.signageId,
imageURL: req.body.imageURL,
page: req.body.page,
pageHeight: req.body.pageHeight,
pageWidth: req.body.pageWidth,
density: req.body.density,
height: req.body.height,
width: req.body.width
});
try {
object.save();
res.json({object});
}
catch (err) {
res.json({message: err});
}
});

Answer 1

Your new object should be something like this.
const newObject = new Objects({
signageId: req.body.signageId,
parameters: {
imageURL: req.body.imageURL,
page: {
height: req.body.pageHeight,
width: req.body.pageWidth,
},
density: {
height: req.body.height,
width: req.body.width,
}
}
});
Notes:
1. Give your mongoose schema another name, in order to avoid javascript conflicts.
2. You can use height and width properties for different objects.
page: {
height: {
type: String
},
width: {
type: String
}
},
density: {
height: {
type: String
},
width: {
type: String
}
}
3. the model properties should be required, not require
