Is there another way to get the request.user by not passing it from the views? I think passing request.user from all functions in views to the template is quite wrong. Is there any method or way that the template will get the user or any object in the database? By default (I am talking about Django version 1.3) you do not need change TEMPLATE_CONTEXT_PROCESSORS. Because default value already contains *django.contrib.auth.context_processors.auth*. So to your question: By default, you should be able to use user , messages and perms variables in your template. For example: User: {{user.username}}

I'm trying to show user group permissions in Django and show them in a "Drupal" style like a matrix. It works, but it takes too long to make the query and paint it in the template. Is there some way to improve my code? view img up(accomplished),down(views and template.html) views : def GroupPermissionsView(request): title = "Groups Permissions" groups = Group.objects.all() permissions = Permission.objects.all() context = Context({ 'title': title, 'groups': groups, 'permissions': permissions, }) return render( request, 'forms_permissions.html', context ) template: <table class="table table

I have the following type of template in Django: <form .... > <label class="control-label" for="id_quantity">Quantiy</label> {{ form.quantity }} <label class="control-label" for="id_title">Quantiy</label> {{ form.title}} </form> The view contains a ModelForm object in its context from which the "form" variable in the template is derived. Often, you can pass a form that is bound to data like request.POST. How do I load a form that is bound to the data of a specific instance of a model? Is there any special syntax? There are two options here: MyModelForm(instance=myInstanceModel) MyModelForm

I'm trying to do a query from another query, but Django said: 'Caught DatabaseError while rendering: subquery returns more than 1 row.' I'm using PostGis. my model class Place(models.Model): coordinate = models.PointField() class TranslatedPlace(models.Model): place = models.ForeignKey(Place) my view near_coordinates = Place.objects.filter(coordinate__distance_lte=(place_obj.coordinate, D(km=100))) near_places = TranslatedPlace.objects.filter(place=near_coordinates) I believe you'll want to use in to filter the second queryset near_coordinates = Place.objects.filter(coordinate__distance_lte=
