Bootstrap Accordion with for-loop in ejs templating engine

Here is how to create Bootstrap Accordion with for-loop in ejs templating engine.
<div class="accordion" id="accordionExample">
<% products.forEach(function(product, index) { %>
<div class="card">
<div class="card-header" id="headingOne">
<h2 class="mb-0">
<button class="btn btn-link" type="button" data-toggle="collapse" data-target="#collapse<%=index%>" aria-expanded="true" aria-controls="collapseOne">
<%=product.title%>
</button>
</h2>
</div>
<div id="collapse<%=index%>" class="collapse show" aria-labelledby="headingOne" data-parent="#accordionExample">
<div class="card-body">
<%=product.productBaseInfoV1.productDescription%>
</div>
</div>
</div>
<% }) %>
</div>
Point to notice is the
id="collepase<%=index5>"
and
data-target="#collapse<%=index%>"
This enables to open each accordion separately. Without it, all tabs will open together on clicking.

Difference between .exec() and .execPopulate() in Mongoose?

Here I answer what is the difference between .exec() and .execPopulate() in Mongoose? .exec() is used with a query while .execPopulate() is used with a document Syntax for .exec() is as follows: Model.query() . populate ( 'field' ) . exec () // returns promise . then ( function ( document ) { console . log ( document ); }); Syntax for .execPopulate() is as follows: fetchedDocument . populate ( 'field' ) . execPopulate () // returns promise . then ( function ( document ) { console . log ( document ); }); When working with individual document use .execPopulate(), for model query use .exec(). Both returns a promise. One can do without .exec() or .execPopulate() but then has to pass a callback in populate.

Resolve: Uncaught TypeError: firebase.database is not a function

If you are getting the error: Uncaught TypeError: firebase.database is not a function Resolve it by including firebase-database.js in your html page as follows: <!-- The core Firebase JS SDK is always required and must be listed first --> <script defer src = "https://www.gstatic.com/firebasejs/6.2.4/firebase-app.js" ></script> <script defer src = "https://www.gstatic.com/firebasejs/3.1.0/firebase-database.js" ></script> That is it. Let me know if this was helpful.
