sorting - Sort alphabetically in rails -

-

how sort array in rails(alphabetical order). tried 

sort_by(&:field_name)

but gives me array capital letter order , lower case order.i tried 

array.sort! { |x,y| x.field_name.downcase <=> y.field_name.downcase }

is there way solve this?

you should first downcase every string , sort like:

array = ["john", "alice", "joseph", "anna", "zilhan"] array.sort_by!{ |e| e.downcase } => ["alice", "anna", "john", "joseph", "zilhan"]

(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...
