在django中创建我自己的上下文处理器

在django中创建我自己的上下文处理器

本文介绍了在django中创建我自己的上下文处理器的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!

问题描述

我已经到了一个点,我需要传递某些变量到我的所有观点(主要是自定义认证类型变量)。



我被告知写自己的上下文处理器是最好的方法,但是我有一些问题。



我的设置文件看起来像这样

  TEMPLATE_CONTEXT_PROCESSORS =(
django.contrib.auth.context_processors.auth,
django.core.context_processors.debug,
django.core.context_processors.i18n,
django.core.context_processors.media,
django.contrib.messages.context_processors.messages,
sandbox.context_processors.say_hello ,

如你所见,我有一个名为'context_processors'的模块,



看起来像

  def say_hello(request):
return {
'say_hello':你好,
}

我是否可以假设我现在可以在我的意见中执行以下操作?

  {{say_hello}} 

现在,这在我的模板中无效。



我的看法看起来像

  from django.shortcuts import render_to_response 

def test(request):
return render_to_response(test.html)
pre>

解决方案

您编写的上下文处理器应该可以工作。您是否认为问题是您的看法。



您是否肯定您的视图是使用 RequestContext 呈现?



例如:

  def test_view(request):
return render_to_response('template.html')

上面的视图不会使用 TEMPLATE_CONTEXT_PROCESSORS 。确保您提供 RequestContext ,如下所示:

  def test_view请求):
返回render_to_response('template.html',context_instance = RequestContext(请求))


I have come to a point where I need to pass certain variables to all of my views (mostly custom authentication type variables).

I was told writing my own context processor was the best way to do this, but I am having some issues.

My settings file looks like this

TEMPLATE_CONTEXT_PROCESSORS = (
    "django.contrib.auth.context_processors.auth",
    "django.core.context_processors.debug",
    "django.core.context_processors.i18n",
    "django.core.context_processors.media",
    "django.contrib.messages.context_processors.messages",
    "sandbox.context_processors.say_hello",
)

As you can see, I have a module called 'context_processors' and a function within that called 'say_hello'.

Which looks like

def say_hello(request):
        return {
            'say_hello':"Hello",
        }

Am I right to assume I can now do the following within my views?

{{ say_hello }}

Right now, this renders to nothing in my template.

My view looks like

from django.shortcuts import render_to_response

def test(request):
        return render_to_response("test.html")
解决方案

The context processor you have written should work. The problem is in your view.

Are you positive that your view is being rendered with RequestContext?

For example:

def test_view(request):
    return render_to_response('template.html')

The view above will not use the context processors listed in TEMPLATE_CONTEXT_PROCESSORS. Make sure you are supplying a RequestContext like so:

def test_view(request):
    return render_to_response('template.html', context_instance=RequestContext(request))
