problems with ejs(data.forEach is not a function)!

Question

Hello so i am trying to run a javascript function inside of a ejs file and this is what my code looks like :

<div class='row'>

<% data.forEach( function( items ) {  %>

    <div class='col-md-4 col-sm-6'>
        <div class="thumbnail">
        <img src="<%= items.img %>" width="350" height="130"></img>    

         <div class="caption">
            <h4><%= items.partname %></h4>
        </div>
        </div>



    </div>

<% }); %>

</div>

when i try and run this inside my ejs file i get this error as a return " 36| 37|

38| <% data.forEach(function(items){ %> 39|
40| 41|

data.forEach is not a function at eval (eval at

does anyone know how to fix this?

this is the backend for my code above:

app.use(bodyParser.urlencoded({extended: true}));
  app.set("view engine","ejs");

var chairSchema=new mongoose.Schema({
    partname:String,
    img:String,
    price:Number
});

var data =mongoose.model("data",chairSchema);

data.create(
{
  partname:"short cylinder",
  img:"http://www.needforseatusa.com/assets/images/products/replacement%20parts/short_cylinder_thumbnail.jpg",
  price:14.90
},
{
  partname:"regular cylinder",
  img:"http://www.needforseatusa.com/assets/images/products/replacement%20parts/cylinder_thumbnail.jpg",
  price:14.90
},{
  partname:"back pillow",

  price:79.99
},function(err,chair){
  if (err){
    console.log(err);
  }
  else{
    console.log("newly created chair");
    console.log(data);
  }

}


);
app.get("/",function(req,res){
    res.render('landing');
});


app.get("/campground",function(req,res){
   data.find({},function(err,data){
      if(err){
        console.log(err);
      }

    });

   res.render("campground", {data:data}); 
});

Here's a sample example of using foreach with ejs, I want you to inspect that data you are sending back to ejs, if it's an Array. Otherwise make sure it is, because foreach is an Array method.

var data = {    
  title: 'Cleaning Supplies',
  supplies: ['mop', 'broom', 'duster']  
};

ejs

<ul>
<% data.supplies.forEach(function(value) { %>
   <li><%= value %></li>
<% }) %>
</ul>

// mop
// broom
// duster
