Answer 1

actually what i was trying to do is to fetch products ordered by a customer related to a particular Ordermodel object and their repective quantity from OrderProductmodel i was giving the order object to inner loop to show products related to that object as
{% for o in objects %}
{% for p in o %}
<tr>
<td>{{forloop.counter}}</td>
<td>{{p.img.url}}</td>
<td>{{o.date}}</td>
<td>{{p.price}}</td>
{% if o.order_status == 'completed' %}
<td><small style="background-color:green;"><span class="badge badge-success">{{o.order_status}}</span></small></td>
{% else %}
<td><small style="background-color:rgb(231, 211, 26);"><span class="badge badge-warning">{{o.order_status}}</span></small></td>
{% endif %}
</tr>
{% endfor %}
{% endfor %}
so how is solved the problem was to fetch order query set object to template via context and inside template used a loop to iterate over queryset and get order object and then created a custom template filter inside templatetags folder to fetch the products related to a particular object by giving order object as argument to the cutstom filter
such as
{%for o in objects %}
<h4>Order{{forloop.counter}}</h4>
<div class="table-responsive">
<table class="table table-bordered">
<thead class="thead-dark">
<tr>
<th>Sno</th>
<th>image</th>
<th>Name</th>
<th>price</th>
<th>Quantity</th>
<th>product total</th>
<th>DateTime</th>
<th>Order Status</th>
</tr>
</thead>
<tbody>
{% for p in o|get_object_related_products:request.session.customer %}
<tr>
<td>{{forloop.counter}}</td>
<td>
<div class="img">
<img src="{{p.img.url}}" alt="Image" height="50px" width="50px">
</div>
</td>
<td>{{p.name}}</td>
<td>{{p.price}}</td>
<td>{{o|get_product_quantity:p}}</td>
<td>{{o|get_order_total:p}}</td>
<td>{{o.date}}</td>
{% if o.order_status == 'completed' %}
<td><small style="background-color:green;"><span class="badge badge-success">{{o.order_status}}</span></small></td>
{% else %}
<td><small style="background-color:rgb(231, 211, 26);"><span class="badge badge-warning">{{o.order_status}}</span></small></td>
{% endif %}
</tr>
{% endfor %}
so thanks to anyone who made consideratiions...
