====== Django Views ======

Devolver el resultado de una función como vista:
<code python>
# En urls:
urlpatterns = [
    path('videos/', views.VideoListView.as_view(), name='videos'),
]

# En views:
from django.http import HttpResponse
def index(request):
    return HttpResponse('Hey yo!')
</code>


===== How to... =====
==== Get data from url ====

=== En generic views ===
If you don't want to pass a pk or slug in your url, you'll need to override the ''get_object'' method and get your object another way.
<code>
path('profile/<username>', views.UserDetailView.as_view(), name='profile')
</code>

<code>
class UserDetailView(generic.DetailView):
    model = apps.get_model('openawards', 'User')
    username = ''

    def dispatch(self, request, *args, **kwargs):
        super().dispatch(request, *args, **kwargs)
        self.username = kwargs.get('username', '')

    def get_object(self):
        return get_object_or_404(get_user_model(), username=self.username)
</code>

:?: Me pregunto si hay otra forma mejor de sacar el parámetro de la url en vez de sobreescribiendo el dispatch. Si!! Siempre puedes acceder a los kwargs de la request:
<code>
return get_object_or_404(get_user_model(), username=self.kwargs.get('username', ''))
</code>

Si los datos viniesen por query string:
<code>
username = self.request.GET.get('username', '')
</code>

Coger la url con la que fue llamada la view:
<code>
request.build_absolute_uri()
</code>

=== Set login_required decorator ===
En el urls.py:
<code>
login_required(ViewSpaceIndex.as_view(..))
</code>
Usando LoginRequiredMixin:
<code>
from django.contrib.auth.mixins import LoginRequiredMixin
class MyView(LoginRequiredMixin, View):
    login_url = '/login/'
    redirect_field_name = 'redirect_to'
</code>
Con el method_decorator:
<code>
from django.utils.decorators import method_decorator
@method_decorator(login_required, name='dispatch')
class ViewSpaceIndex(TemplateView):
    template_name = 'secret.html'
</code>

=== Other decorators for user control ===
<code>
from django.contrib.auth.decorators import user_passes_test

@user_passes_test(lambda u: u.is_superuser)
def my_view(request):
    ...
</code>

<code>
from django.contrib.admin.views.decorators import staff_member_required

@staff_member_required
def my_view(request):
    ...
</code>
