can't use a field of the database in django template

I have a database like this:

from django.db import models


class User(models.Model):
    firstName = models.CharField(max_length=30, blank=False, default=None)
    lastName = models.CharField(max_length=30, blank=False, default=None)
    email = models.EmailField(max_length=100, blank=False, default=None)
    password = models.CharField(max_length=100, blank=False, default=None)
    score = models.IntegerField(default=0)

in views.py I want to send a user that currently logged in and show its informations from DB at template.
my views.py:

user = User.objects.filter(email=request.POST['email'])
#some code ....
context = RequestContext(request, {
    'user': user[0]
})
return HttpResponse(template.render(context))

my template :

{% if user %}
    Wellcome {{ user.firstName }}
{% endif %}

but I don't see anything after welcome.also when I use this:

{% if user %}
    Wellcome {{ user }}
{% endif %}

I see welcome anonymousUser where I am wrong ?

You cannot use user as the context variable, as it conflicts with the user object that is injected into the context by the processor

django.contrib.auth.context_processors.auth

Now, to fix your issue, rename user to user_obj or something which makes more sense.

Based on the behavior you are describing you are likely not getting any objects returned from the call to filter:

user = User.objects.filter(email=request.POST['email'])

I would look at the value that is returned from request.POST['email'] and making sure that value is in your datbase as the starting point.

Also, you should be aware that the filter function returns a QuerySet and not a User object. If you want to retrieve a unique User object you can use the get function instead.
