Sorting Products

Sorting Products

Learn to sort the products based on an attribute.

We'll cover the following...

We can sort our products based on their price in the admin and category routes. We need to add the sorting buttons and sort the products in the controllers of these routes.

Adding sorting buttons

Let’s add ascending and descending sort buttons. We’ll also add a button to clear the sorting in our admin.hbs and category/index.hbs templates.

Adding buttons in the admin.hbs template

Open the app/templates/admin.hbs template and add the sort and clear buttons:

Node.js
{{!-- app/templates/admin.hbs --}}
{{page-title "Admin"}}
<br>
  {{!-- Create product div--}}
<div class="row">
	
  <div class="col-4 add_edit">
        <LinkTo class='btn btn-success' @route="admin.add" >Add Product</LinkTo>
        {{!-- <LinkTo class='btn btn-success' @route="admin.edit" @model="123">Edit</LinkTo> --}}
		<hr>
		{{outlet}}  
  </div>
	<div class="col-8 products">
    {{!-- search div --}}
    <div class="row">
			<div class="col-md-8">
				<form class="form-inline">
					<div class="form-group" style="display: inline-block;">
						{{input type="text" class="form-control" value=filter  id="search" placeholder="Search Products..."}}
          </div>
          <div style="display: inline-block;">
				    <button type="submit" {{action 'search'}} class="btn btn-primary">Search</button>
          </div>
				</form>
			</div>
            {{!-- sorting div --}}
        <div class="col-md-4 sorting-div">
            <button  class="btn btn-primary" type="button" {{action 'sortasc'}}>Sort Asc.</button>
            <button class="btn btn-primary" type="button" {{action 'sortdsc'}}>Sort Dsc.</button>
            <button class="btn btn-danger" type="button" {{action 'clear'}}>Clear</button>
        </div>
            
            
	</div>
    {{!-- search div end --}}
    {{!-- product div --}}
    <div class="row">
      {{#if this.appliedfilter }}
        
        {{#each filteredProducts as |item|}}
          <div class="col-lg-4 col-md-6 col-sm-6 col-12">
          <br>
          <AdminProduct @source={{item.imglink}} @title={{item.product_title}} @desc={{item.desc}} @price={{item.price}} @route="admin.edit" @model={{item.id}}/>
          </div> 
        {{/each}}
        
        
      {{else}}
          {{#each @model as |item|}}
            <div class="col-lg-4 col-md-6 col-sm-6 col-12">
              <br>
              <AdminProduct @source={{item.imglink}} @title={{item.product_title}} @desc={{item.desc}} @price={{item.price}} @route="admin.edit" @model={{item.id}}/>
            </div> 
          {{/each}}
      {{/if}}
    </div>
    {{!-- product div end --}}
  </div>
</div>
