The url: myurl/?page=1&reverse
Now I want to check in the template whether reverse is in there:
{% if request.GET.reverse %}
do somthing
{% endif %}
But what's in between of if and endif never happens!
What should I use instead of request.GET.reverse?
Why not put that logic inside your view? Like this:
# Function Based View (FBV)
def my_view(request):
reversed = request.GET.get('reverse', '')
return render(request, 'template.html', locals())
# Class Based View (CBV)
class MyView(ListView):
template_name = 'path/to/template.html'
queryset = MyModel.objects.filter(...)
context_object_name = 'my_obj'
def get_context_data(self, **kwargs):
context = super(MyView, self).get_context_data(**kwargs)
context['reversed'] = self.request.GET.get('reverse', '')
return context
Then do:
{% if reversed %}
do somthing
{% endif %}
On the other hand, if you still want to do this kind of logic in your template then you should create your own filter like this:
from django import template
register = template.Library()
def is_in_dict(d, key):
return key in d
and use it like this:
{% load my_filters %}
{% if request.GET|is_in_dict:"reverse" %}
do somthing
{% endif %}
reversed to context?
reversed in this case would be falsey, since it's an empty string, even if the key exists. It would be better to use something like this: reversed = 'reverse' in request.GET
