Get user information in django templates

Question

What's the best way to get user information from a django template?

For example, if I just want to:

1. If the user is logged in, display "Welcome [username]"
2. Otherwise, display the login button.

I'm using django-registration/authentication

Answer 1

An alternate method for current Django versions:

{% if user.is_authenticated %}
    <p>Welcome, {{ user.get_username }}. Thanks for logging in.</p>
{% else %}
    <p>Welcome, new user. Please log in.</p>
{% endif %}

Note:

• Use request.user.get_username() in views & user.get_username in templates. Preferred over referring username attribute directly. Source
• This template context variable is available if a RequestContext is used.
• django.contrib.auth.context_processors.auth is enabled by default & contains the variable user
• You do NOT need to enable django.core.context_processors.request template context processor.

Answer 2

{% if request.user.is_authenticated %}Welcome '{{ request.user.username }}'
{% else %}<a href="{% url django.contrib.auth.login %}">Login</a>{% endif %}

and make sure you have the request template context processor installed in your settings.py:

TEMPLATE_CONTEXT_PROCESSORS = (
    ...
    'django.core.context_processors.request',
    ...
)

As per the question title, the following may come handy to someone. used the followings in my template:

Username: {{ user.username }}

User Full name: {{ user.get_full_name }}

User Group: {{ user.groups.all.0 }}

Email: {{ user.email }}

Session Started at: {{ user.last_login }}

Thanks :)

Answer 4

Firstly, First, if your fields changed their name, you must overwrite the functions (get_full_name(), get_short_name(), etc), in this way:

def get_full_name(self):
    return self.names + ' ' + self.lastnames

def get_short_name(self):
    return self.names

In the template, you can show it this way

{% if user.is_authenticated %}
<strong>{{ user.get_short_name }}</strong>
{% endif %}

these are the methods in authentication https://docs.djangoproject.com/es/2.1/topics/auth/customizing/
