I have such a top nav-bar in the base.html

<div class='section-topbar'>

  <div class="row">

    <nav class="col-md-12">

      <ul class="nav nav-tabs nav-justified">

        {% for sec in sections %} {% if sec == current_section %}

        <li class="active">

          <a href="/article/list/{{ current_section.id }}">{{ current_section.name }}</a>

        </li>

        {% else %}

        <li>

          <a href="/article/list/{{ sec.id }}">{{ sec.name }}</a>

        </li>

        {% endif %} {% endfor %}

        <br class="cbt">

      </ul>

    </nav>

  </div> <!--first row-->

</div>

It is designed to present on every single page, and retrieve two contextual parameter sections and current_section from the view,

context = {"page":page,

           "current_section": section,

           "sections": sections,}

return render(request, "article/article_list.html", context)

So I have to pass the extra parameters to templates from every views,

Is it possible to pass them in one go and enable them globally?

Write your own context_processor which will inject the given variables in every view's context and they will be available in every template.

# myproject/myapp/context_processors.py



def sections_processor(request):

    # do something ...

    # then return your variables

    return {'sections': sections, 'current_section': section}

You'll need to register this context processor in your settings file so that Django will run it:

# myproject/myproject/settings.py



TEMPLATES = [{

    'OPTIONS': {

        'context_processors': [

            ...

            'myappp.context_processors.sections_processor',

        ]

    }

}]

Yes it is, you can use context_processors, so every template yours will have by default this variable loaded... but keep in mind all your pages must be able to run the code inside your context_processor

https://docs.djangoproject.com/pt-br/2.0/_modules/django/template/context_processors/

EDIT: Here some code so you can try this out

settings.py

TEMPLATES = [{

    'BACKEND': 'django.template.backends.django.DjangoTemplates',        

    'DIRS': ,

    'APP_DIRS': True,

    'OPTIONS': {

        'context_processors': [                

            ...

            'youapp.context_processors.yourcontextname_context_processor',

        ],

    },

}]

context_processors.py # Create it inside your app

def yourcontextname_context_processor(request):

    ... # Your logic        

    data = {

        'something': "something",

        'another_thing': "another_thing",

        'array_of_thing': ["thing", "thing", "thing", ],

    }



    return data

in your html

{{ something }}

{{ another_thing }}

{% for thing in array_of_thing %}

    {{ thing }}

{% endfor %}
