My Nested {{#each}} does not work. I am Scraping article titles to my page and I'm using MongoDB/Mongoose. For each article (that I named News) I want user to post comments and view previous comments. My routes, console.log, and the database itself shows that my api routes are working, but I can't get the comments to display. My handlebars has the articles rendering to screen, but when GETting the comments it returns a 304.
The Articles display as I intend, it only has a problem with the comments {{#each News}} is each article {{#each comment}} is nested inside each News.
{{#each News}}
<div class="panel-block is-active">
<ul>
<li>
<div class="level-left">
<h2 class="subtitle">
<a href="https://www.atptour.com{{this.url}}">
{{this.headline}}
</a>
</h2>
</div>
</li>
<li>
<img width="348" src="https://www.atptour.com{{this.thumbNail}}">
</li>
<li>
<p>{{category}}</p>
</li>
<li>
{{!-- on click remove class .is-hidden on #getComments --}}
<p id="showComments" data-id="{{this._id}}" >Comments</p>
</li>
<li>
{{#each comment}}
<article id="getComments" class="media is-hidden">
<div class="media-content">
<div class="content">
<p>
<small>{{this.time}}</small>
<br />
{{this.body}}
</p>
</div>
</div>
<div class="media-right">
<button class="delete"></button>
</div>
</article>
{{/each}}
{{!-- on click remove class .is-hidden on #postComments --}}
<a id="addComment" >Add Comment</a>
{{!-- TO POST A COMMENT --}}
<article id="postComment" class="media is-hidden">
<div class="media-content">
<div class="field">
<p class="control">
<textarea
class="textarea"
placeholder="Add a comment..."
></textarea>
</p>
</div>
<div class="level">
<div class="level-left">
<div class="level-item">
<a class="button is-info">Submit</a>
</div>
</div>
</div>
</div>
</article>
</li>
</ul>
</div>
{{/each}}
In the {{#each comment}} {{this.time}} and {{this.body}} is blank. But if I simply put {{this}} I get the _id if each comment. The context must be wrong but I don't know why. The comments are properly associated to the News because I can check the get route and it's all there correctly.
Here are the schemas if it helps
new articles
const NewsSchema = new Schema({
headline: {
type: String,
required: true,
},
thumbNail: {
type: String,
required: true,
},
category: {
type: String,
required: true,
},
url: {
type: String,
required: true,
},
// Comments will populate the News
comment: [
{
type: Schema.Types.ObjectId,
ref: "Comment",
},
],
});
const News = mongoose.model("News", NewsSchema);
comments
const CommentSchema = new Schema({
time: {
type: Date,
default: Date.now,
required: true,
},
body: {
type: String,
required: true,
},
});
const Comment = mongoose.model("Comment", CommentSchema);
It wasn't a handlebars problem at all! It was a route problem.
I was doing this:
app.get("/", function(req, res) {
db.News.find()
.then(News => {
res.render("index", { News });
})
.catch(err => {
console.log(err);
});
});
When I should have been doing this
app.get("/", function(req, res) {
db.News.find()
.populate("comment")
.then(News => {
res.render("index", { News });
})
.catch(err => {
console.log(err);
});
});
I forgot to populate in the res.render. (I was populating the api route, but not this 1!)
