Question

我有一个带有应用程序的django 1.6.2项目，该应用程序是一个带有产品和postgresql数据库的商店。一切都配置好了，虽然没有发现要显示的图像。

使用

> <a href="/{{ p.mainphoto }}"><img HEIGHT=175 WIDTH=175 src="{{
> p.mainphoto.name }}"></a>

结果来源显示：

<a href="/webapps/static/images/14333.jpg"><img HEIGHT=175 WIDTH=175 src="/webapps/static/images/14333.jpg"></a>

显然无法显示图像。

这是我的模型的样子

class ProductImage(models.Model):
    property = models.ForeignKey('Product', related_name='images')
    image = models.ImageField(upload_to='/static/images', blank=True)
    def filename(self):
        return os.path.basename(self.image.name)


class Product(models.Model):   
    name = models.CharField(max_length=300) 
    designers = models.ManyToManyField(Designer, blank=True, verbose_name = 'designer/artist')
    width = models.DecimalField(blank=True, max_digits = 8, decimal_places=1, null=True)
    height = models.DecimalField(blank=True, max_digits = 8, decimal_places=1, null=True)
    depth = models.DecimalField(blank=True, max_digits = 8, decimal_places=1, null=True)
    diameter = models.DecimalField(blank=True, max_digits = 8, decimal_places=1, null=True) 
    description = models.TextField()    
    colors = models.ManyToManyField(Color, blank=True)
    materials = models.ManyToManyField(Material, blank=True)
    mainphoto = models.ImageField(upload_to='/static/images', blank=True)
    morephotos = models.ManyToManyField(ProductImage, blank=True)
    manufacturer = models.CharField(max_length=300, blank=True)    
    price_in_dollars = models.DecimalField(max_digits=6, decimal_places=2)
    type = models.ManyToManyField(FurnitureType, verbose_name = 'furniture/art type')
    def __unicode__ (self):
        return self.name
    def filename(self):
        return os.path.basename(self.mainphoto.name)

这是什么视图：

from django.shortcuts import render
from django.shortcuts import render_to_response
from django.http import HttpResponse
from django.template.loader import get_template
from django.template import RequestContext
from django.views.generic.list import ListView
from django.utils import timezone
from store.models import Product

def home(request):
        return render_to_response('homepage.html')

def designhomepage(request):
        return render_to_response('designserviceshome.html')

def eventspage(request):
        return render_to_response('events.html')

def aboutpage(request):
        return render_to_response('about.html')

def returnpage(request):
        return render_to_response('returnpolicy.html')

def privacypage(request):
        return render_to_response('privacypolicy.html')

def hello(request):
        name = ""
        html = "<html><body>Hi %s. </body></html>" % name
        return HttpResponse(html)

def hellonew(request):
        name = ""
        t = get_template('hello.html')
        html = t.render(Context({'name': name}))
        return HttpResponse(html)

def inventory(request):
        products = Product.objects.all()

        productinfo = {
        "product_detail": products
        }
        return render_to_response('inventory.html', productinfo, context_instance=RequestContext(request))

和网址文件：

from django.conf.urls import patterns, include, url
from django.contrib import admin
from store.models import Product
admin.autodiscover()

urlpatterns = patterns('', 
# Examples:

    ... urls
    )

urlpatterns += staticfiles_urlpatterns()
urlpatterns += static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT)

我只想从下面的代码中获取“14333.jpg”并在它之前添加网站网址，然后让python自动添加带有for循环的图像名称让我们知道你获取该东西的想法在引号

<a href="/webapps/static/images/1333.jpg"><img HEIGHT=175 WIDTH=175 src=""></a>

我通过以下方式解决了这个问题：

class ProductImages(models.Model):
product = models.ForeignKey('Product3', related_name='images')
image = models.ImageField(upload_to='/webapps/static', blank=True)

def __unicode__(self):
    return os.path.basename(self.image.name)

def filename(self):
    return os.path.basename(self.image.name)


class Product3(models.Model):
category = models.CharField(max_length=300)
slug = models.SlugField(max_length=150, blank=True) 
name = models.CharField(max_length=300)
designers = models.CharField(max_length=300, blank=True)
manufacturer = models.CharField(max_length=300, blank=True)
description = models.TextField()
quantity = models.DecimalField(max_digits=6, decimal_places=2, blank=True)
price_in_dollars = models.DecimalField(max_digits=6, decimal_places=2)
width = models.DecimalField(max_digits=6, decimal_places=2, blank=True)
depth = models.DecimalField(max_digits=6, decimal_places=2, blank=True)
diameter = models.DecimalField(max_digits=6, decimal_places=2, blank=True)
height = models.DecimalField(max_digits=6, decimal_places=2, blank=True)
photo = models.ImageField(upload_to='/webapps/static', blank=True)
materials = models.CharField(max_length=300, blank=True)
style = models.CharField(max_length=300, blank=True)
timeperiods = models.CharField(max_length=300, blank=True)
country = models.CharField(max_length=300, blank=True)  
additionalphotos = models.ManyToManyField(ProductImages, blank=True)



def __unicode__(self):
    return self.name

def filenamemain(self):
    return os.path.basename(self.photo.name)

这个模型看起来像这个重要的部分是def文件名（自我）部分

接下来是在模板中添加正确的调用，如下所示:(注意{{p.filename}}）

{%block body_content %}

    <div class="">

            <div id="manyphotos">
            {% for p in itemdetail %}
            <a href="http://www.yoursite.com/static/{{p.filename}}"><img HEIGHT=175 WIDTH=175 src="http://www.yoursite.com/static/{{p.filename}}" border="0"></a>
            {% endfor %}

            </div>


    </div>

{％endblock％}

使用正确的主键正确浏览整个数据库并显示所有可用图像。

此视图如下所示：

def itemdetailpage(request, id):
    property = Product3.objects.get(pk=id)
    property1 = property.images.all()
    itemin = {"itemdetail": property1 }
    return render_to_response('details.html', itemin, context_instance=RequestContext(request))
