I have 3 collections in mongodb generated by strapi.io, I want customize query populate data by mongoose in my project. But i cannot populate data like strapi result.
Category collection:

I can populate "posts" on Category model with
Cat.find().populate({path: 'posts',model: 'Post'})
But I can not populate "categories" and "pic" on Post model.
How can I populate "categories" and "pic" like this result of strapi:

you have to create another collection inside the post. as like you have an independent collection then you can populate. for example :
Post: {body: ,title: ,Image : { image: {name : , etc }}}
this can be a collection inside collection. the above code is not correct you have to mention your own fields.

I am not sure how to phrase this question properly but basically I have an "Order" Schema and each order model contains an array of product objects created using "Product" Schema
When I create an order, my req.body is this
body: {
orderItems: [ [Object] ],
shippingAddress: {
fullName: '123',
address: '1231',
city: '123',
postalCode: '123',
country: '123'
},
shippingPrice: 0,
paymentMethod: 'Stripe',
itemsPrice: 338,
totalPrice: 338
},
If I log req.body.orderItems, I can see each product object printed
{
_id: new ObjectId("62d51a3895cad3ca283302f3"),

}
But I am unable to obtain the 'shop' field. req.body.orderItems.shop returns undefined
Data:
_id: ObjectId(''),
restaurantId: ObjectId(''),
orderId: ObjectId(''),
reviews: [
{
type: "food",
tags: ["good food", "nice food"]
},

type: "pricing",
tags: ["best price", "good price"]

Group by restaurant id
Get total reviews by type: Ex: food: 3, pricing: 2, ambience: 1
Group by type and tags and get counts:
Ex: food-superb: 1, food-loudt:2, pricing-superb: 2, ambience-superb: 1
Expected result:
{
_id: restaurantId,
types: {

I'm using Strapi with Mongodb and y was trying with the following code:
const requiredData = {

cover: { url: 1 }
}
const populateData = [
{
path: 'category',
select: ['title', 'slug']
}
]
let editorsPick = await strapi.query('posts')
.model.find({ editorsPick: true}, requiredData)
.limit(3)
.populate(populateData)
But I only have this:
{
_id: 60d9295db34f1c0144c9b8d4,
title: 'Este es el titulo',
slug: 'este-es-el-titulo',
date: '2021-06-27',
category: {
_id: 60d92921b34f1c0144c9b8d2,
title: 'Categoria 1',
slug: 'categoria-1',
id: '60d92921b34f1c0144c9b8d2'
},
id: '60d9295db34f1c0144c9b8d4'
}
(Without cover image), and then try with:
let editorsPick = await strapi.query('posts')
.model.aggregate([
{"$match": { editorsPick: true}},
{"$project": requiredData}
])
But I got an empty array []
Please I need a little help, and sorry for my english
I have seen this asked several times, but I haven't found a solution that has worked. I am trying to query a MongoDB using Mongoose .findById and am not getting the expected results. find({id: "..."}) is also not returning anything.
Using find without any parameters displays all of the expected results including id key-value pairs, but I cannot use the id value in the query.
Using mongoose: 5.4.9
const mongoose = require('mongoose');
mongoose.connect('mongodb://localhost/mongo-exercises', { useNewUrlParser: true });
const courseSchema = new mongoose.Schema({
name: String,
author: String,
tags: [String],
date: { type: Date, default: Date.now },
isPublished: Boolean,
price: Number
});
const Course = mongoose.model('Course', courseSchema);
async function getCourses() {
return await Course
.find()
}
async function run() {
const result = await getCourses();
console.log(result);
}
run();
//Return

That code verifies I'm connected to the correct database and retrieving real ids. When I modify the getCourses function as shown below, I get null or an empty array depending on whether I use findById or find({id: "..."}).
async function getCourses() {
return await Course
.findById('5a68fdf95db93f6477053ddd')
}
//null
async function getCourses() {
return await Course
.find({ id: '5a68fdf95db93f6477053ddd' })
}
// []
async function getCourses() {
return await Course
.find({ _id: '5a68fdf95db93f6477053ddd' })
}
// []
Any help would be greatly appreciated. Thank you!
EDIT: Showing full find() response.
Upon our discussion as your importing the data from JSON file, So its inserting the _id as string, While finding the document by _id, moognoose automatically converting string to Object.
// Original JSON
{
"_id": "5a68fde3f09ad7646ddec17e",
"tags": [
"aspnet",
"backend"
],
"date": "2018-01-24T21:42:59.605Z",
"name": "ASP.NET MVC Course",
"author": "Mosh",
"isPublished": true,
"price": 15,
"__v": 0
}
Solution 1 :
To insert the _id as in the JSON, change your _id field with $oid as below,
{
"_id": { "$oid": "5a68fde3f09ad7646ddec17e" },
"tags": [
"aspnet",
"backend"
],
"date": "2018-01-24T21:42:59.605Z",
"name": "ASP.NET MVC Course",
"author": "Mosh",
"isPublished": true,
"price": 15,
"__v": 0
}
Solution 2 :
Remove _id from your JSON, MongoDB will generate a _id automatically
{
"tags": [
"aspnet",
"backend"
],
"date": "2018-01-24T21:42:59.605Z",
"name": "ASP.NET MVC Course",
"author": "Mosh",
"isPublished": true,
"price": 15,
"__v": 0
}
Hi I am wondering which is the best solution to work with related resources in ember-data.
In order to build a REST backend.
1) embedded resources
user: {
id: "foo",
albums: [
album: {
id: "foo",
name: "bar",
description: "foobar",
},
album: {
id: "foobar"
name: "foobarfoo",
description: "fumanchu",
},
],
}
2) embedded id of the resources
user: {
id: "foo",
albums: [
album: {
id: "foo",
},
album: {
id: "foobar"
},
],
}
3) linked resources
user: {
id: "blabla",
links: {
"self": { "href": "/users/blabla" },
"albums": { "href": "/albums/blabla" }
},
}
Do you think is possible to use hipermedia as in HATEOAS?
Thanks in advance
Did you have a look at ActiveModelSerializers gem?
It is the easier way to get the job done when working with Rails on the server side.
For relations, it may embed or use references to sub-resources. References (which I would recommend) are serialized this way:
{
users: [{
id: 42,
firstName: "John",
albums: [ 1, 2, 3 ]
}]
}
{
albums: [{
id: 1,
name: "Foo"
}, {
id: 2,
name: "Bar"
}, {
id: 3,
name: "Buzz"
}]
}
Here, albums may also be included as sideloaded data in the first hash:
{
users: [{
id: 42,
firstName: "John",
albums: [ 1, 2, 3 ]
}],
albums: [{
id: 1,
name: "Foo"
...
}]
}
