Newbie : Help for using RequestContext

[Mickae...@gmail.com]

Hello to all Django users :-)

I'm new to Django and this is my first post.

I'd like to implement breadcrumbs on all my pages.

My strategy is to create a middleware and to use RequestContext to
add a dict to the context of each request then use the context in my html

My problem is that I don't understand how to link RequestContext to
my request. Hereafter my code :

my_middleware.py

from django.template import RequestContext


class SimpleBreadcrumbs(object):
    def __init__(self, get_response):
        self.get_response = get_response
        # One-time configuration and initialization.


    def __call__(self, request):
        # Code to be executed for each request before
        # the view (and later middleware) are called.

        request_context = RequestContext(request)
        request_context.push({"level0": "Adrian", "level1": "Thomas"})

        response = self.get_response(request)


        # Code to be executed for each request/response after
        # the view is called.

        return response

my_template.html

{% extends 'pricing/body.html' %}

{% block content %}

{{ level0 }}

{% endblock content %}

What I'm doing wrong ?

Thx for your help

Hi Micka,

And welcome to django.

Regarding how to add things in middleware - you can add the information to the session like this:

class SimpleBreadcrumbs(object):
    def __init__(self, get_response):
        self.get_response = get_response
        # One-time configuration and initialization.


    def __call__(self, request):
        # Code to be executed for each request before
        # the view (and later middleware) are called.

        request.session['breadcrumbs'] = {"level0": "Adrian", "level1": "Thomas"}

        response = self.get_response(request)


        # Code to be executed for each request/response after
        # the view is called.

        return response

Then in your templates you can do this:

{% extends 'pricing/body.html' %}

{% block content %}

{{ breadcrumbs.level0 }} / {{ breadcrumbs.level1 }}

{% endblock content %}

Regards,

Andréas

Oh, Thank you Andréas for your kind attention and your reactivity.

Nice, I didn't know about request.session... And thanks to you, now I Know :-)

Just for archive, I found a way with context_processors here (old django version, but I adapt to django 2) :

Very happy to join Django community :D
