rails nested model forms has_one association -

-

im using simple_form gem , need nested form im having trouble here code:

i have 2 models:

apiphones:

class apiphone < activerecord::base   attr_accessible :key, :phone   validates_presence_of :phone   belongs_to :store end

stores:

class store < activerecord::base   has_one :apiphone   accepts_nested_attributes_for :apiphone end

and in view:

<%= simple_form_for [@group,@store] |f| %>     <%= f.simple_fields_for :apiphone |ph| %>       <%= ph.input :phone %>     <% end %> <% end %>

but nothing showing, ideas?

using fields_for in conjunction accepts_nested_attributes assumes records initialized. means that, using models, @store.apiphone should not nil when form generated. way solve issue making sure apiphone initialized , associated @store (both new , edit actions).

def new   @store = store.new   @store.build_apiphone end

-
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...
