Hi folks, 

I am very new to django and facing some problems. 

1. I need a global variable, which I can use throughout the application. Like let's say base_url. 

• I tried defining one variable in settings and using it places like this 
• from django.conf import settings
• url = settings.BASE_URL+'login'
• This gives me an error : non-keyword arg after keyword arg
• Also this process seems to be painful, every time I have to import settings in each of my views.

2. I need a custome context variable to be passed everytime. 

• I tried this: in the same directory where my settings is, I created a context_processors.py
• context_processors.py:
  
• def baseurl(request):
• return {"base_url" : "/some/url/"}
• In my settings.py file I am adding this line :

• TEMPLATE_CONTEXT_PROCESSORS += ('context_processors.baseurl',)

• This gives me an error : NameError: name 'TEMPLATE_CONTEXT_PROCESSORS' is not defined

Please help me on these issues.

Hi Sudipta,

You can do this in one of 2 ways:

1. Add it to your settings file, like you have done. I would however write : url = "%s/login" % settings.BASE_URL instead.

2. Add a context processor. You should in your settings.py add:

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.core.context_processors.static",

    "django.core.context_processors.tz",

    "django.contrib.messages.context_processors.messages",

    "django.core.context_processors.request",

    "context_processors.baseurl",

)

That includes the normally added context processors (at least those that we have in our project at the moment).

Regards,

Andréas
