python - Pass values into Django form before form is made -


in forms.py file, let's have this...

class exampleform(forms.modelform):   class model:     model = example     fields = ['date_field']     widgets = {       'date_field' : selectdatewidget(years=year_range(some_variable))     }     exclude = ()

if wanted put some_variable while form being created , instance (form = exampleform(request.post or none, instance=instance_variable)), how 1 set value some_variable in form?

you should in form's constructor:

class exampleform(forms.modelform):     ...     def __init__(self, *args, **kwargs):         some_variable = kwargs.pop('some_variable')         super(exampleform, self).__init__(*args, **kwargs)         self.fields['date_field'].widget = selectdatewidget(                                                  years=year_range(some_variable))

and create form this:

form = exampleform(request.post or none,                    instance=instance_variable,                    some_variable=2015)

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.
