Django上下文/模板:呈现多个结果

Question

我有这样的代码，我希望它能够返回多个产品。现在它只返回最后一个。我认为这是因为变量被覆盖了，但我不知道其他方法来修复它

def result(request):
rawquery = request.GET.get('q') #gets the product name to search from a form
Product_set = Product.objects.filter(name__icontains=rawquery).distinct()
for product in Product_set:
name = product.name
id = product.id
store_name = product.store_name
Price_set = Scan.objects.filter(product=id)
for price in Price_set:
current_price = price.price
context = {
'name': name,
'store_name': store_name,
'price': current_price,
'query': rawquery
}
return render(request, 'result.html', context)

这是模板

%  {extends 'base.html' %}
{%  block content %}
<h1>Results for {{ query }} </h1> 
<p> {% if name %} {{name}} {% else %} None {% endif %} | {% if store_name %} {{store_name}} {% endif %} | {% if price %} {{price}} {% endif %} </p>

{% endblock content %}

Answer 1

您必须将产品附加到列表中：

def result(request):
rawquery = request.GET.get('q') #gets the product name to search from a form
Product_set = Product.objects.filter(name__icontains=rawquery).distinct()
products = []
for product in Product_set:
price = Scan.objects.filter(product=product.id).first()
products.append({
'name': product.name,
'store_name': product.store_name,
'price': price.price
})
return render(request, 'result.html', {'query': rawquery, 'products': products})

你现在可以在这里循环产品：

{% extends 'base.html' %}
{%  block content %}
<h1>Results for {{ query }} </h1> 
{% for product in products %}
<p> {{product.name}} | {{product.store_name}} | {{product.price}} </p>
{% endfor %}

{% endblock %}
