ruby on rails 3 - Redmine: extend controller action in plugin -

-

need in plugin development. i've created hook in user/edit form view, added ballance_amount form , have "ballance_amount"=>"1".

how can extend default update action in user controller?

in base.class_eval do i've added alias_method_chain :update, :ballance in instancemethods:

def update_with_ballance     ballance.amount = params[:user][:ballance_amount].to_f #i have ballance association end

and this:

nameerror (undefined local variable or method `params' #<user:0x007f972e9379d0>): app/controllers/users_controller.rb:144:in `update'

how can fetch params?

you should able make use of mass-assignment code in redmine itself. line 135 in userscontroller should handle provide simple entry point extension, if balance_amount considered safe_attribute. achieve that, add patch following user model:

module redminebalanceplugin::userpatch   def self.included(base)     base.class_eval       safe_attributes 'balance_amount'        include instancemethods     end   end    module instancemethods     # method indirectly called when creating or updating user     def balance_amount=(amount)       balance.amount = amount     end      # useful in view patch, maybe not     def balance_amount       balance.amount     end   end end  user.send(:include, redminebalanceplugin::userpatch)

if example not help, helpful, if provide more code fragments - e.g. complete patch userscontroller, make easier reproduce , analyse issue.

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...
