How can I get the username of the logged-in user in Django?

Question

How can I get information about the logged-in user in a Django application?

For example:

I need to know the username of the logged-in user to say who posted

Answer 1

request.user.get_username() or request.user.username, former is preferred.

Django docs say:

Since the User model can be swapped out, you should use this method instead of referencing the username attribute directly.

P.S. For templates, use {{ user.get_username }}

Answer 2

You can use the request object to find the logged in user

def my_view(request):
    username = None
    if request.user.is_authenticated():
        username = request.user.username

According to https://docs.djangoproject.com/en/2.0/releases/1.10/

In version Django 2.0 the syntax has changed to

request.user.is_authenticated

Answer 3

For classed based views use self.request.user.id

Answer 4

request.user.get_username() will return a string of the users email.

request.user.username will return a method.

Answer 5

'request.user' has the logged in user.
'request.user.username' will return username of logged in user.

Answer 6

if you are using the old way of writting views, in the way of Function-Based-Views...

in your view, you are creating a new variable called usuario to save the request.user probably...

but if you returning to the Template a context_instance, passing the value of the Context of the request, you will get the logged user, just by accessing the request.

// In your views file
from django.shortcuts import render_to_response
from django.template import RequestContext
def your_view(request):
    data = {
        'formulario': Formulario()
        # ...
    }
    return render_to_response('your_template.html',
        data, context_instance=RequestContext(request))


// In your template
<form id='formulario' method='POST' action=''>
    <h2>Publica tu tuit, {{ request.user.username.title }} </h2>
    {% csrf_token %}
    {{ formulario.as_p }}
    <p><input type='submit' value='Confirmar' /></p>
</form>
