regex - Named groups in Django based off model field? -


i trying replicate url regex equivalent to:

url(r'^members/(?p<username>\w+)/$', 'profiles.views.single'),

while understand taking users exist within database from: 

from django.contrib.auth.models import user

i wondering if can change little more unique. i've been reading documentation from: https://docs.djangoproject.com/en/1.8/intro/tutorial04/ still lost.

my question regarding whether or not can use data model named group in regex expression.

example:

from django.db import models django.contrib.auth.models import user  class address(models.model):     user = models.foreignkey(user)     unique_code = models.integerfield(max_length = 5)     active = models.booleanfield(default = true)

is somehow possible use 'unique_code' field possible url in regex map like:

 url(r'^members/(?p<unique_code>\w+)/$', 'profiles.views.single'),

i trying this, didn't work:

def single(request, unique_id):     try:         uid = get_object_or_404(address, unique_id=unique_id)         final = uid     except:         raise http404      return render_to_response('single_user.html', locals(), context_instance=requestcontext(request))

try replace unique_id in function unique_code

def single(request, unique_code): try:     uid = get_object_or_404(address, unique_code=unique_code)     final = uid except:     raise http404  return render_to_response('single_user.html', locals(), context_instance=requestcontext(request))

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
