python - appending foreign key reference in django json response -

-

during appending result (appending foreign key ) causes key error

models.py

class table1     id = models.integerfield( primary key=true)     ref = models.foreignkey('table2')  class table2     name = models.charfield()     id = models.integerfield(primarykey= true)     address = models.charfield()

views.py

def relation(request) """     stuff """     query = "query set makes object of table 1"      result['content'].append([query['ref__address'])

the error 

keyerror @ /url ref__address 

def relation(request, pk):     item = get_object_or_404(table1, pk=pk)     context= {'content': item}     return render(request, 'table1/relation.html', context)  urlpatterns = patterns('',     url(r'^table1/(?p<pk>\d+)/$', relation, name='relation'), )

your problem seems none of python valid.

(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...
