Ruby composition/design quandary -

-

i trying create convinience method called:

def signin_screen

end

which should have 2 components.

  1. all common methods devicescreen's signin_screen
  2. specific methods either android/ios (which determined @ runtime based in env variable)

signinscreen have methods 

 def emailfield   end    def passwordfield    end

but may have common methods , specific methods.

now androidscreen , iosscreen subclasses of devicescreen. design signinscreen, should class under each of these or module?

please don't add emphasis android/ios/screens etc. person student faculty/staff, need have common authentication class

better explanation pen , paper

i don't have experience in specific topic answer based on general ideas.

in opinion, signinscreen serves controller prepare content show, while both androidscreen , iosscreen should nothing more templates. content controller , show on specific device.

by design, signinscreen(or better name without screen since controller or controller action) better nothing devicescreen or sub classes, , better parent applicationcontroller

i'm new python, question might easy, anyway, patience: as trying call newton-raphson method calculate implied volatility in black-scholes formula call/put option pricing, first thing is, newton method in scipy.optimize seems calculate function's zeros, in black-scholes formula, want function's value option price, not zero. (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...
