ruby - Get erb view from inside layout -

-

i trying name of current view being loaded layout.erb. trying inject js file , css file layout head. building name files based on name of erb view:

<link rel="stylesheet" href="/devcss/<%= viewname%>.css"> <script src="/devjs/<%= viewname %>.js" type="text/javascript"></script>

how can layout template?

update:i not interested in knowing how inject script in specific place in layout, think content_for used for. need knok in example above how determine viewname variable

insert following application.html.erb after inside head tag

<%= "#{yield(:scripts)}".html_safe if content_for?(:scripts) %>

and in individual erb, insert similar following

<% content_for :scripts %>     <link rel="stylesheet" href="/devcss/<%= viewname%>.css">     <script src="/devjs/<%= viewname %>.js" type="text/javascript"></script> <% end %>

this allow insert page specific codes head , other tags not accessible individual erbs

(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...
