Use of "#each" with multiple variables in Handlebars - handlebars.js

Question

How to "select" a value with "this" when there are multiple #each in Handelbars ?
{{#each marqueauction}}
{{#each modelauction}}
<div class="results__container--box">
{{this.marqueauction}}
{{this.modelauction}}
</div>
{{else}}
<div class="results__container--box">
<p>Aucun résultat d'enchères n'est disponible pour ce modèle.</p>
</div>
{{/each}}
{{/each}}
EDIT: I want to call my MongoDB database with mongoose and display results in a box container. For that, I loop through my results array.
My Mongoose model:
const DemocarauctionSchema = new Schema({
objectID: {
type: Number
},
cars_getroute: {
type: String
},
gm_url: {
type: String
},
"results": { type: [{
marque: {
type: String
},
model: {
type: String
},
model_year: {
type: String
},
price_str: {
type: String
},
prince_int: {
type: Number
},
price_currency: {
type: String
},
sold: {
type: Boolean
},
auction_house: {
type: String
},
auction_country: {
type: String
},
auction_date: {
type: String
},
auction_datetime: {
type: String
},
auction_url: {
type: String
},
image_urls: {
type: String
},
price_int_eu: {
type: Number
},
}]}
}
I loop through the array in Express/Node:
const [democarauctions] = result;
let marqueauction = [];
for (let i = 0; i < democarauctions.results.length; i++) {
marqueauction.push(democarauctions.results[i].marque)
}
let modelauction = [];
for (let i = 0; i < democarauctions.results.length; i++) {
modelauction.push(democarauctions.results[i].model)
}
...
And I call the results array in my "res.render":
res.render(demo, {
results: democarauctions.results,
marqueauction: marqueauction,
modelauction: modelauction,
modelyearauction: modelyearauction,
etc.})
Now I'd like to render on my HTML multiple box for each result, with marqueauction, modelauction, modelyearauction in each one. I use handlebars.

Answer 1

It is best to avoid this and instead use named block parameters :
{{#each marqueauction as |marque|}}
{{#each modelauction as |model|}}
<div class="results__container--box">
{{marque}}
{{model}}
</div>
{{else}}
<div class="results__container--box">
<p>Aucun résultat d'enchères n'est disponible pour ce modèle.</p>
</div>
{{/each}}
{{/each}}
I'm not sure why you are breaking apart the original collection into multiple collections and then trying to combine them again in the presentation. Just use the results directly.
EDIT: based on your updated question:
{{#each results as |auction|}}
<div class="results__container--box">
{{auction.marque}}
{{auction.model}}
</div>
{{else}}
<div class="results__container--box">
<p>Aucun résultat d'enchères n'est disponible pour ce modèle.</p>
</div>
{{/each}}
