Вопрос:
я пытаюсь извлечь запись заказов из модели заказов и передать в качестве контекста в шаблон, но в шаблоне возникает проблема, когда я использую цикл внутри цикла, например
{% 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 %}
я извлекаю продукты, связанные с конкретным объектом заказа, и передаю в качестве контекста с этим конкретным объектом заказа
, таким как

1. Привет! Можете ли вы поделиться своим мнением?
Ответ №1:
на самом деле, что я пытался сделать, так это получить продукты, заказанные клиентом, связанные с определенным объектом Ordermodel, и их количество в модели OrderProduct. Я передавал объект заказа во внутренний цикл, чтобы показать продукты, связанные с этим объектом, как
{% 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 %}
Итак, как решается проблема была в том, чтобы принести порядок набора запроса элемента в шаблон через контекст и внутри шаблона используется цикл для итерации через объект QuerySet и вам того объекта, а затем создает шаблон фильтра внутри папку templatetags для получения продуктов, относящихся к определенному объекту, давая тем объектом в качестве аргумента в cutstom фильтр
например
{%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">
<a href="#"><img src="{{p.img.url}}" alt="Image" height="50px" width="50px"></a>
</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 %}
так что спасибо всем, кто проявил внимание…
