In your single view that processes every state I would define the
queryset you're interested in:
state_infos = {
# 'Explicit is better than implicit.'
'AK': Jurisdiction.objects.get('Alaska'),
'AL': Jurisdiction.objects.get('Alabama'),
}
Then in the view:
try:
state_data = state_infos[twodigit]
except KeyError:
# something not defined in your dict was entered.
from django.contrib import messages
messages.error(request, "That state hasn't been accepted into the "
"union yet. Try again.")
return HttpResponseRedirect(my_index)
To answer your question more directly, I think what is happening is
you're confusing your variables with your strings.
for k, v in statedict:
if k:
print('v')
This will return 'v' for everything because v is a string. What you
probably meant to do is print the value of each element.
for k, v in statedict:
if k:
print(v)
Hope that helps
