send data while redirect to view in django

Is it possible to send data while to redirecting to another view?

For example:-

def social_user():
//do something here
 return redirect('name of the view',{'variable':'value'})

or any other alternative to exchange data between a function and view function.

First Solution::

If you have access to the request variable in social_user, you can simply make use of sessions. Sessions are the best way to transfer data between 2 views.

def social_user(request):
    request.session['variable'] = 'value'
    return redirect('name of the view')

Then inside your view, you can access this variable using request.session.get('variable')

Second Solution::

In case you can't set session variables, send them as query parameters.

def social_user():
    //do something here
     return redirect("your_view/?variable=value")

There are two ways to send data to the resulting destination, but first you should understand how redirects work.

When the server redirects, it just sets the Location header telling the browser which page to fetch next.

Location: /foo.html

Since the body is completely ignored even if present, you must somehow pass data via the HTTP headers.

1) Query Parameters

The easiest way is to use query (GET) parameters which you can then read from the destination page:

Location: /foo.html?username=bob

The downside is that the user can easily see and modify this value.

2) Cookies

The session, which is determined by cookies, is another place to store temporary data. But this has several downsides:

  • It is not tied to any request, so you all consequent request will have access to the data until you delete it.

  • It doesn't work if the user has disabled cookies. On the other hand query parameters always work.

If you choose the first option, you may need to write some of your own code since Django doesn't seem to offer a convenient method to do this (someone correct me if I'm wrong). Here's a sample function that wraps the functionality:

def redirect_with_query(path, query=None, *args, **kwargs):
    if query is None:
        query = {}

    url = resolve_url(path, *args, **kwargs)

    if len(query):
        q_dict = QueryDict(mutable=True)
        q_dict.update(query)
        url += '?' + q_dict.urlencode()

    return HttpResponseRedirect(url)

Use render() and pass the variable via context:

def social_user(request)
    // do something here
    return render(request, template_name='template.html', context={'variable': 'value'})

  1. Build a "mock django request" manually and call the view directly
  2. Use query parameters
