您好Djangonauts,
我想在“订单历史记录”页面(ListView)中添加一些“订单详细信息”(DetailView),请参见下面的图像示例(我已经在photoshop中制作了图像)。我能够获得灰色部分(要显示的订单列表),但无法获得要在此页面中显示的项目详细信息。如果单击View Order Detail
,它将转到详细信息页面,在此可以显示所有这些信息。但我也需要ListPage中的一个小摘要,也请参见下面的示例
下面是我的 view.py
class OrderHistory(LoginRequiredMixin, ListView):
model = Order
template_name = 'order/order_list.html'
def get_context_data(self, **kwargs):
context = super(OrderHistory, self).get_context_data()
context['order_details'] = Order.objects.filter(emailAddress=self.request.user.email)
context['order_items'] = OrderItem.objects.filter(order=self.kwargs.get("order"))
return context
我什至尝试过
# context['order_items'] = OrderItem.objects.filter(order__id=self.kwargs.get("order.id"))
下面是我的 models.py
from django.db import models
class Order(models.Model):
token = models.CharField(max_length=250, blank=True)
total = models.DecimalField(max_digits=6, decimal_places=2, verbose_name='USD Order Total')
emailAddress = models.EmailField(max_length=100, blank=True, verbose_name='Email Address')
created = models.DateTimeField(auto_now_add=True)
billingName = models.CharField(max_length=350, blank=True)
billingAddress1 = models.CharField(max_length=350, blank=True)
billingCity = models.CharField(max_length=100, blank=True)
billingZipcode = models.CharField(max_length=10, blank=True)
billingCountry = models.CharField(max_length=50, blank=True)
class OrderItem(models.Model):
product = models.ForeignKey(Product, on_delete=models.CASCADE)
quantity = models.IntegerField()
price = models.DecimalField(max_digits=5, decimal_places=2, verbose_name='USD Price')
order = models.ForeignKey(Order, on_delete=models.CASCADE)
def sub_total(self):
return self.quantity * self.price
我还在下面附上我的产品型号。以防万一,如果您需要查看
class Product(models.Model):
name = models.CharField(max_length=250)
slug = models.SlugField(max_length=250)
description = models.TextField(blank=True)
price = models.DecimalField(max_digits=10, decimal_places=2)
image = models.ImageField(upload_to='product', blank=True)
stock = models.IntegerField(default=True)
下面是我的模板。此问题不需要它。我相信我在views.py中做错了。但是我以防万一。
{% extends 'base.html' %}
{% load staticfiles %}
{% block body %}
<div>
<div class="text-center">
<br/>
<h1 class="text-center my_title">Tasting Order Purchase History</h1>
<br/>
{% if order_details %}
{% for order in order_details %}
<div class="row order_detail_div" >
<div class="col-md-2">
<b>Order Number: 156{{ order.id }}</b><br/>
<small><em>Order Date: {{ order.created|date:"M d Y" }}</em></small>
</div>
<div class="col-md-1"></div>
<div class="col-md-3 text-left">
<b>Status: Paid</b><br/>
<b>Total items in Order: ()</b>
</div>
<div class="col-md-1"></div>
<div class="col-md-3 order_total_text">
<b>Order Total: ${{ order.total }}</b>
</div>
<div class="col-md-2 view_order_details">
<b><a href="{% url 'order:order_detail' order.id %}">View Order Details</a></b>
</div>
</div>
<!--------------------------This is the code for OrderItem that's not working------->
{% for item in order_items %}
<div class="row order_item_detail_div">
<div class="col-md-2">
a <!--This a does not show either -->
<img src="{{ item.product.image }}" >
</div>
</div>
{% endfor %}
<!--------------------------Code ends here ----------------------------------->
{% endfor %}
{% else %}
<p>
You do not have any orders yet.<br/><br/>
<a href="{% url 'home' %}" class="btn btn-secondary">Add more recipes</a>
</p>
{% endif %}
</div>
</div>
<br/>
<br/>
{% endblock %}
任何有关如何进行这项工作的建议
答案 0 :(得分:1)
在您的模板中,您尝试显示不存在的图像,因为您的产品字段是CharField,因此没有与之关联的图像字段。您的OrderItem模型上的产品是否应该是产品模型的外键?
请注意,您需要在模板中的图像上调用url()方法,即{{product.image.url}}。请参阅FileField上的文档: https://docs.djangoproject.com/en/2.0/ref/models/fields/#filefield
在您的模板中,尝试将item.price或数量显示为文本字段,以证明您的查询集有效。
