Django query - create record will not return ID -

-

i experiencing weird behavior , not sure why, able without issue in view.

here's issue: creating , saving new record database, after save not give me id new record null, though record being inserted db without error.

my code: 

    r = ksprojectrewards()     r.project_id = project_id     r.reward_description_short = desc_short     r.reward_description_long = desc_long     r.limit_max = limit     r.international_info = international     r.is_active = active     r.save()      r.id  # <!-- returns null

here model

class ksprojectrewards(models.model):     id = models.integerfield(primary_key=true)     project_id = models.integerfield()     reward_description_short = models.charfield(max_length=75l, blank=true)     reward_description_long = models.charfield(max_length=500l, blank=true)     num_backers = models.integerfield(null=true, blank=true)     limit_count = models.integerfield(null=true, blank=true)     limit_max = models.integerfield(null=true, blank=true)     limit_met = models.integerfield(null=true, blank=true)     delivery_date = models.datetimefield(null=true, blank=true)     international_info = models.charfield(max_length=200l, blank=true)     date_added = models.datetimefield()     date_updated = models.datetimefield(null=true, blank=true)     is_active = models.integerfield()     class meta:         db_table = 'ks_project_rewards'

you try remove following line model:

id = models.integerfield(primary_key=true)

django takes care auto incremented field.

(i'm new here programming, i'm not sure techniques.) should write function things like: def f(sigma, price): return bsformula(s0,k,r,t,q,sigma) - price then, while calling newton method, takes args=() 1 parameter in function, write this: value = newton(bsprice2, 0.5, args=price) but error message: file "bs.py", line 36, in bsimpvol value = newton(bsprice2, 0.5, args=float(price)) file "/usr/lib/python2.7/dist-packages/scipy/optimize/zeros.py", line 143, in newton q0 = func(*((p0,) + args)) typeerror: can concatenate tuple (not "float") tuple could tell me why that? how fix it? apprecia...
