python - Django Admin, Call function on save -


i have app in django site handles blog post. when blog post published want schedule newsletter on third party application informs subscribers of new post.

so want add custom function called when blog post saved can write api call newsletter service.

how this? tried looking through documentations , can find admin actions doesn't seem i'm looking for.

there number of approaches use.

override model save method simple, called every time model saved.

https://docs.djangoproject.com/en/1.8/ref/models/instances/#saving-objects

if specific admin site, in modeladmin use model_save() method. (i approach personally, won't interfere model).

https://docs.djangoproject.com/en/1.8/ref/contrib/admin/#django.contrib.admin.modeladmin.save_model

you use post save signal, save methods seem preferred (depending on doing) django: when customize save vs using post-save signal

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.
