django 上传图片 有时候出现叉叉的情况

 

这个是项目settings里边的设置

 

 

STATIC_URL = '/static/'STATICFILES_DIRS = (os.path.join(BASE_DIR, 'static').replace('\\', '/'),)  MEDIA_ROOT = os.path.join(BASE_DIR,'polls').replace('\\','/')MEDIA_URL='/polls/'

然后是model里边的代码，主要定义了ImageField

 

from django.db import models

class Yangyang(models.Model):        record_date = models.DateTimeField("time")    record_img = models.ImageField(upload_to='img',null=True,blank=True)    recorder= models.CharField(max_length=200)        def __unicode__(self):        return self.recorder

 

 

然后是view，主要是detail的。

from django.shortcuts import render,render_to_responsefrom django.http import HttpResponsefrom .models import Yangyang# Create your views here.def index(request):    latest_question_list = Yangyang.objects.all()    context = {'latest_question_list': latest_question_list}    return render(request, 'polls/index.html', context)def detail(request, question_id):    try:        question = Yangyang.objects.get(pk=question_id)    except Yangyang.DoesNotExist:        raise Http404("Question does not exist")    return render_to_response( 'polls/detail.html', {'question': question})

好吧，detail的代码是相当简单的

 

<img src="{{question.record_img.url}}">

polls 的url配置

 

<p>from django.conf.urls import url,patternsfrom django.conf import settingsfrom django.conf.urls.static import static</p><p>from . import views</p><p>urlpatterns = [    # ex: /polls/    url(r'^$', views.index, name='index'),    # ex: /polls/5/    url(r'^(?P<question_id>[0-9]+)/$', views.detail, name='detail'),        # ex: /polls/5/results/    #url(r'^(?P<question_id>[0-9]+)/results/$', views.results, name='results'),    # ex: /polls/5/vote/    #url(r'^(?P<question_id>[0-9]+)/vote/$', views.vote, name='vote'),</p><p>]</p><p>urlpatterns += static(settings.MEDIA_URL,document_root=settings.MEDIA_ROOT)</p>  

开始以为这样就行了，但是每次方位都是图片无法现实的图标，路径看上去也没问题

 

后来发现最后一句的位置不对。

 

要放到网站下边的urls

from django.conf.urls import include, urlfrom django.contrib import adminfrom django.conf import settingsfrom django.conf.urls.static import staticurlpatterns = [    url(r'^polls/', include('polls.urls', namespace="polls")),    url(r'^admin/', include(admin.site.urls)),]urlpatterns += static(settings.MEDIA_URL,document_root=settings.MEDIA_ROOT)

 

最后直接访问：

http://127.0.0.1:8000/polls/4/ 就可以了
