In a Django template, is it possible to send the whole variable document to a template tag?

Question

If I render a template using this document:

{ "a": 1, "b": 2 }

In Django templates, I can render html using the value of "a" like this:

{{ a }}

But is it possible to send the whole document to a template tag? ie, all this?

{ "a": 1, "b": 2 }

So that my tag can access arbitrary elements?

Answer 1

Just pass your dict as string or you can use json to this for you.

Example 1

def index(request):
    my_dict = '{"a":1, "b":2}'
    return render(request, "index.html", {'data':my_dict})

Example 2

import json

def index(request):
    my_dict = json.dumps({"a":1, "b":2})
    return render(request, "index.html", {'data':my_dict})

and inside your template just do like this

{{data}} <!--- this will output actual dictionary eg. { "a": 1, "b": 2 } --->

Answer 2

In django framework we send data from view.py to template using context dictionary. The general format for this is:

1. using function based views.

   def index(request):

   return render(request, 'index.html',{'injectme':'this is context',
   'inject_me':'this is next context'})
   

now in template you can access this as:

{{injectme}}    
{{inject_me}}

2. using class based views

   class abc(TemplateView):

   def get_context_data(self,**kwargs):
       context=super().get_context_data(**kwargs)
       context['inject_me']='basic injection'
       context['injectme']='second injection'
       return context
   

now in the template:

{{inject_me}}
{{injectme}}

hope your confusion cleared out.
