在选择选项中显示图像

Question

我正在做一个项目，我被卡在订单页面上了

这里，我想在选项标签中显示产品图像列表，以便用户可以从所有图像中选择一个图像，或者可以上传图像，上传图像的功能正常工作，但选择不起作用。

• 我想向用户显示图像，以便用户可以选择其中一个。

models.py

class Product(models.Model):
prod_ID = models.AutoField("Product ID", primary_key=True)
prod_Name = models.CharField("Product Name", max_length=30, null=False)
prod_Desc = models.CharField("Product Description", max_length=2000, null=False)
prod_Price = models.IntegerField("Product Price/Piece", default=0.00)
prod_img = models.ImageField("Product Image", null=True)
class ImageTemplate(models.Model):
temp_id = models.AutoField("Template ID", primary_key=True, auto_created=True)
temp_img = models.ImageField("Template Image", null=False)
class ImageTemplateProductMapping(models.Model):
imageTemp_p_map_id = models.AutoField("Template Image & Product Map ID", primary_key=True, auto_created=True)
temp_id = models.ForeignKey(ImageTemplate, null=False, on_delete=models.CASCADE,
verbose_name="Image Template ID")
prod_id = models.ForeignKey(Product, null=False, on_delete=models.CASCADE, verbose_name="Product Id")

views.py

def order(request, id):
products = Product.objects.all()
ImageTemplateProductsList = []

try:
ImageTemplateProductsMap = ImageTemplateProductMapping.objects.filter(prod_id=id)
ImageTemplateProductsList = [data.temp_id.temp_img for data in
ImageTemplateProductsMap]
except AttributeError:
pass
context = {'products': products,
"ImageTemplateProductsList": ImageTemplateProductsList
}
return render(request, 'user/order.html', context)

我用jquery稍微修改了我的html模板，并改变了一点视图，现在它正在为我工作。

order.html

{% extends 'user/layout/userMaster.html' %}
{% block title %}Order{% endblock %}
{% block css %}
.t {
display: none;
}
img:hover {
opacity:0.8;
cursor: pointer;
}
img:active {
opacity:0.5;
cursor: pointer;
}
input[type=radio]:checked + label > img {
border: 20px solid rgb(228, 207, 94);
}
#dropdown{
height: 50px;
width: 50%;
font-size: 20px;
margin-left: 10px;
margin-top: 3px;
}
{% endblock %}
{% block header %}

我已经使用隐藏字段来检查用户是否试图上传图像或选择图像，并根据我正在采取的决定，我应该做什么:

views.py

def order(request, id):
products = Product.objects.all()
ImageTemplateProductsList = []
try:
ImageTemplateProductsMap = ImageTemplateProductMapping.objects.filter(prod_id=id)
ImageTemplateProductsList = [data.temp_id.temp_img for data in
ImageTemplateProductsMap]
except AttributeError:
pass
if request.method == 'POST':
try:
if request.POST['templateValue'] == 'Upload':
if 'image' in request.FILES:
Template_Value1 = request.FILES['image']
fs = FileSystemStorage()
fs.save(Template_Value1.name, Template_Value1)
TemplateValue = Template_Value1.name
elif request.POST['templateValue'] == 'Select':
TemplateValue = request.POST['image2']
else:
pass
except MultiValueDictKeyError:
pass
order_store = Order(product_img=TemplateValue)
order_store.save()
context = {'products': products,
"ImageTemplateProductsList": ImageTemplateProductsList
}
return render(request, 'user/order.html', context)
