I'm new to django so i could be asking a dumb question, but how am i supposed to forward URL A's named parameter to URL B?
For example:
URL A = https://stackoverflow.com/questions?parameter=1
URL B = https://stackoverflow.com/ask
What i actually want is:
URL B = https://stackoverflow.com/ask?parameter=1
I need to do this because i need to pass those parameters to the view that is being called at the second url, could someone help me?
EDIT1 The views that are at play are this two:
class HostServiceListView(BaseFilterView, ListView):
template_name = 'services/service_list.html'
model = HostService
paginate_by = 15
context_object_name = 'services'
filterset_class = HostServiceFilterSet
def exportHostServices(request):
hsqs = HostService.objects.filter(hostname__icontains=request.GET.get("hostname_input", ''),\
ip__icontains=request.GET.get("ip_input", ''),\
port__icontains=request.GET.get("port_input", ''),\
servicename__icontains=request.GET.get("servicename_input", ''))
df = read_frame(hsqs)
# my "Excel" file, which is an in-memory output file (buffer)
# for the new workbook
excel_file = IO()
# pylint shows a false positive error here,
# so the alert is suppressed with the comment after the code
xlwriter = pd.ExcelWriter(excel_file, engine='xlsxwriter') # pylint: disable=abstract-class-instantiated
df.to_excel(xlwriter, 'Host Services')
xlwriter.save()
xlwriter.close()
# rewind the buffer
excel_file.seek(0)
# set the mime type so that the browser knows what to do with the file
response = HttpResponse(excel_file.read(),\
content_type='application/vnd.openxmlformats-officedocument.spreadsheetml.sheet')
# set the file name in the Content-Disposition header
response['Content-Disposition'] = 'attachment; filename=Anagrafica-Servizi.xlsx'
return response
The urls.py is configured this way:
urlpatterns = [
path('services/', HostServiceListView.as_view(), name='services'),
path('services/exportHostServices/', exportHostServices, name='exportHostServices'),
path('', IndexFilterView, name="index")
]
Finally, the button i've got in html that needs to call exportHostServices with the query-string so i can get the parameters:
services/service_list.html
{% extends 'services/base.html' %}
{% load paginatedfilter %}
{% block title %}Host Services{% endblock title %}

Figured out atlast what was wrong with the code. The problem was that the form where i passed the querystring was defaulted at GET:
<form action="{% url 'exportHostServices' %}?{{ request.GET.urlencode }}">
The fix was to simply convert it to a POST form so the querystring could be passed to the view:
<form action="{% url 'exportHostServices' %}?{{ request.GET.urlencode }}" method="post">
