How get current user in a template tag?

Question

How can i get the current user in a django template tags? (request object is not accessible) Or how can i access to request object?

You can create it as context processor than creating template tags and call it always in a template. In context processor you can get the user without calling the function in a template always. — catherine, Feb 11 '13 at 15:11
Really complicated for a one liner template tag.. Is really django so unhandly? — tapioco123, Feb 11 '13 at 15:14
What do you want to show then? If it's not useful then your question is incomplete. If you really want help be nice, be more specific and give sample. — catherine, Feb 11 '13 at 15:22
The question is pretty clear, he wants to access the current user in a template tag — msc, Feb 11 '13 at 15:36
@msc I give him sample on how to access current user but he replied it's not really he really want. Then what he really want? I understand what his question above. — catherine, Feb 11 '13 at 15:52
He wants to either access the current user object in a template tag, or the request object in a template tag. Not in a context processor, or as a variable in the template. — msc, Feb 11 '13 at 16:00

If you want to access the current user in a template tag, you must pass it as a parameter in the templates, like so:

{% my_template_tag user %}

Then make sure your template tag accepts this extra parameter. Check out the documentation on this topic. You should also check out simple tags.

The user is always attached to the request, in your templates you can do the following:

{% if user.is_authenticated %}
{% endif %}

You don't have to specify "request" to access its content

UPDATE:

Be aware: is_authenticated() always return True for logged user (User objects), but returns False for AnonymousUser (guest users). Read here: https://docs.djangoproject.com/en/1.7/ref/contrib/auth/

`user.is_authenticated` always returns true so it's basically useless. – markwalker_ Jan 28 '15 at 10:26
no! It always return true for User (logged ones), but returns false for AnonymousUser, so is not useless! Read here carefully: https://docs.djangoproject.com/en/1.7/ref/contrib/auth/ – daveoncode Jan 29 '15 at 08:25

This question was already answered here:

{% if user.is_authenticated %}
    <p> Welcome '{{ user.username }}'</p>
{% 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',
...
)

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.

Suppose you have a profile page of every registered user, and you only want to show the edit link to the owner of the profile page (i.e., if the current user is accessing his/her profile page, the user can see the edit button, but the user can't see the edit button on other user's profile page. In your html file:

<h2>Profile of {{ object.username }}</h2>
{% if object.username == user.username %}
    <a href="{% url 'profile_update' object.pk %}">Edit</a>
{% endif %}

Then your urls.py file should contain:

from django.urls import path
from .views import ProfileUpdateView
urlpatterns = [
    ...
    path('<int:pk>/profile/update', ProfileUpdateView.as_view(), name = 'profile_update'),
    ...
]

considering you have appropriate ProfileUpdateView and appropriate model
