*Thanks coolguy I changed my urls.py to this and that resolved the error:*
from django.urls import include, path
from . import views
from .views import search
app_name= "searchLit"
urlpatterns=[
path('customsearch/', views.search, name='search'),
path('exportlit/', views.searchLit_export, name='SearchLit_export'),
path('noccustomsearch/', views.nocSearch, name='nocSearch'),
path('exportnoc/', views.noc_export, name='noc_export'),
path('exportSearch/<str:params>/', views.exportSearch,
name='exportSearch'),
]
*I now am getting:*
Reverse for 'exportSearch' with arguments '("{'circuitid': '', 'bandwidth':
'Select Bandwidth', 'region': 'Central', 'carrier': 'Select Carrier',
'status': 'Select Status', 'segmentname': 'Select Segment', 'mrcnew': '',
'diversity': 'Select Option', 'kmz': 'Select YES/NO', 'multipleSearch':
''}",)' not found. 1 pattern(s) tried:
['searchlit\\/exportSearch\\/(?P<params>[^/]+)\\/$']
*When I try to use this code in my template to pass a dictionary(containing
my search parameters) to the export function to export only filtered table
data:*
*template:*
<a href="{% url 'searchLit:exportSearch' paramString %}"><input
type="button" value="Self Destruct" /></a>
*views.py:*
def exportSearch(request, params):
params = ast.literal_eval(params)
search_vector = SearchVector('circuitid', 'carrier', 'pathname',
'segmentname', 'segmentid', 'alocationaddress', 'alocationcity', 'alocst',
'zlocationaddress', 'zlocationcity', 'zlocst', 'handoffalocaddress',
'handoffalocst',
'handoffaloccity', 'handoffzlocaddress',
'handoffzloccity', 'handoffzlocst', 'latestjiraticket',
'installciopsticket', 'retermciopsticket', 'discociopsticket', 'notes',
'diversitynotes')
allcircuits=filterCircuits(params, search_vector)
return render_to_csv_response(allcircuits)
*I assume that I need to use a different path converter but I am unsure.
Any tips am I thinking about this the right way or is there a better way to
do what I am trying to do?*
