how to display a single prouct from database in mongodb and node.js
Question
we have created a e-commerce project in that while clicking on categories in UI it will renders to category page in that page it has show one product of each subcategory
i have written the code in which the entire products with the specific category name is displaying how i can remove the extra products as of now i required only one product of each sub category of the particular category
the routing code is
router.get("/shop/:category_name", function(req, res){
//querystring
var url = require('url');
var url_parts = url.parse(req.url, true);
var query = url_parts.query;
var viewModel = {
breadCrumb: [],
categories : [],
featuredProducts :[],
products : [],
};
viewModel.breadCrumb.push({
name : 'Home',
class : 'breadcrumb-ordinary'
});
viewModel.breadCrumb.push({
name : req.params.category_name,
class : 'breadcrumb-active'
});
async.parallel({
categories: function(cb){
Category.find({}, cb);
},
categories1:function(cb){
Category.find({category_name:req.params.category_name}, cb);
}
}, function(err, results) {
if (err) throw err;
viewModel.categories1=results.categories1;
viewModel.categories=results.categories;
res.render('shop/prod_grid',viewModel);
});
});
the view UI code is
<!doctype html>

In Your Router Code, Edit this section
categories1:function(cb){
Category.find({category_name:req.params.category_name}, cb);
}
Change the above to this
categories1:function(cb){
Category.findOne({category_name:req.params.category_name}, cb);
}
That should solve it for you.
