views.py:
def index(request):
return render_to_response('index.html', {})
def photos(request, artist):
if not artist:
return render_to_response('photos.html', {'error' : 'no artist supplied'})
photos = get_photos_for_artist(artist)
if not photos:
logging.error('Issue while getting photos for artist')
return render_to_response('photos.html', {'error': 'no matching artist found'})
return render_to_response('photos.html', {'photos': photos})
index.html的:
<html>
<head>
<title>find artist photos </title>
</head>
<body>
{% block error %} {% endblock %}
<form action="/photos" method="POST">
{% csrf_token %}
<label for="artist">Artist : </label>
<input type="text" name="artist">
<input type="submit" value="Search">
</form>
{% block content %}{% endblock %}
</body>
</html>
photos.html:
{% extends 'index.html' %}
{% block error %}
{% if error %}
<p> {{ error}} </p>
{% endif %}
{% endblock %}
{% block content %}
{% if photos %}
{% for photo in photos %}
{{ photo }}
{% endfor %}
{% endif %}
{% endblock%}
url.py:
urlpatterns = patterns('',
(r'', index),
(r'^time/$', current_datetime),
(r'^photos/(\w+)$', photos)
)
我甚至尝试添加{% csrf_token %},但没有运气
谢谢
更新
我在日志中看到了这些
UserWarning: A {% csrf_token %} was used in a template, but the context did not provide the value. This is usually caused by not using RequestContext.
warnings.warn("A {% csrf_token %} was used in a template, but the context did not provide the value. This is usually caused by not using RequestContext.")
将context_instance = RequestContext(request)**添加到render_to_response()**之后

添加context_instance=RequestContext(request)到您将在其中使用表单的每个视图:
return render_to_response('index.html', {}, context_instance=RequestContext(request) )
return render_to_response('photos.html', {'photos': photos}, context_instance=RequestContext(request) )
假设您使用的是相当新版本的Django(1.3/1.4/dev),您应该按照以下步骤操作:
settings.py,将中间件添加django.middleware.csrf.CsrfViewMiddleware到
MIDDLEWARE_CLASSES列表中.{% crsf_token %}表单中的内容.django.core.context_processors.csrf通过以下方式使用上下文处理器:
RequestContext来自django.templatefrom django.core.context_processorsfrom django.template import RequestContext
from django.shortcuts import render_to_response
def my_view(request):
return render_to_response('my_template.html', {}, context_instance=RequestContext(request))
要么
from django.core.context_processors import csrf
from django.shortcuts import render_to_response
def my_view(request):
c = {csrf(request)}
return render_to_response('my_template.html', c)
