我通过django教程非常好,并且感觉非常好。
然后我开始尝试使用these suggestions for integrating matplotlib。第一步是包含一个静态图像,这就是我想要做的。细节:
我的文件层次结构如下:
djOakData:
djOakData:
__init__.py
settings.py
urls.py
wsgi.py
manage.py
showCrime:
__init__.py
admin.py
models.py
templates:
showCrime:
index.html
tests.py
tstImage.JPG
urls.py
views.py
sqlite.db
templates:
base_site.html
djOakData/urls.py
有:
from django.conf.urls import patterns, include, url
from django.contrib import admin
admin.autodiscover()
from showCrime import views
urlpatterns = patterns('',
url(r'^$', views.index, name='index'),
url(r'^showCrime/', include('showCrime.urls')),
url(r'^admin/', include(admin.site.urls)),
)
djOakData/showCrime/urls.py
有:
from django.conf.urls import patterns, url
import views
urlpatterns = patterns('',
url(r'^$', views.index, name='index'),
url(r'^tstImage.JPG$', views.index, name='showImage'),
)
djOakData/showCrime/views.py
有:
from django.http import HttpResponse
from django.template import Context, loader
def index(request):
template = loader.get_template('showCrime/index.html')
context = context = Context({})
return HttpResponse(template.render(context))
def showImage(request):
imagePath = "/Users/rik/Code/eclipse/djOakData/showCrime/tstImage.JPG"
from PIL import Image
Image.init()
i = Image.open(imagePath)
response = HttpResponse(mimetype='image/jpg')
i.save(response,'JPG')
return response
然后我的index.html
就在其中:
<h1>ShowCrime Index</h1>
<img src="/showCrime/tstImage.JPG" width="500px">
(也试过离开/showCrime
;仍然没有离开。)
我尝试了很多其他变种。他们中的许多人抛出404错误,但这个版本没有。相反,我只是在日志中得到了我期望的那种消息,要么试图通过index.html引用图像,要么试图直接指向它:
[11/May/2013 13:50:44] "GET /showCrime/tstImage.JPG HTTP/1.1" 200 391
[11/May/2013 13:50:44] "GET /showCrime/ HTTP/1.1" 200 391
对我正在做什么新事物的任何猜测?谢谢你的帮助。
答案 0 :(得分:0)
您的tstImage网址指向索引视图,而不是showImage网址。
