python - Django admin.py readonly_fields not working -


i need show on django administration date object created, date field should disabled of modification.

here model on models.py

from django.db import models django.utils import timezone  class mymodel(models.model):     name = models.charfield(max_length=200)     date_of_creation = models.datefield(default=timezone.now)

here admin.py

from django.contrib import admin .models import mymodel  class mymodeladmin(admin.modeladmin):     readonly_fields = ('date_of_creation',)  admin.site.register(mymodel)

the "save() override set date of creation" isn't case here.

i tried this snippet , django documentation already, can't find mistake.

please note i'm beginner in django, , first app.

thank in advance.

you need register admin class model. 

admin.site.register(mymodel, mymodeladmin)

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.
