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 a Review:

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

In usuario.username.title I get the username, but in the template, I need to get that information from the view.

Answer 1

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 2

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 }}
