Rails update method not working: ActionView::MissingTemplate (Missing template items/update...) -

-

the following update method in items_controller:

def update     @item = item.find(params[:id])     if @item.update_attributes(item_params)       flash[:success] = "item updated"       redirect_to edit_item_path(@item)     else       render edit_item_path(@item)     end   end

the @item seems loaded in logs, after completed 500 internal server error in 73ms occurs:

item load (6.7ms)  select  "items".* "items" "items"."id" = ? order "items"."created_at" desc limit 1  [["id", 30]] completed 500 internal server error in 54ms  actionview::missingtemplate (missing template items/update, application/update {:locale=>[:en], :formats=>[:html], :variants=>[], :handlers=>[:erb, :builder, :raw, :ruby, :coffee, :jbuilder]}. searched in:  * "/library/ruby/gems/2.0.0/gems/web-console-2.0.0.beta3/lib/action_dispatch/templates"  * " # app route # "  * "/library/ruby/gems/2.0.0/gems/web-console-2.0.0.beta3/app/views"  ):  actionview (4.2.0) lib/action_view/path_set.rb:46:in `find'  actionview (4.2.0) lib/action_view/lookup_context.rb:121:in `find'  actionview (4.2.0) lib/action_view/renderer/abstract_renderer.rb:18:in    `find_template'  etc.

it seems @item.update_attributes(item_params) might not doing anything. clue how fix ?

this should following:

def update     @item = item.find(params[:id])     if @item.update_attributes(item_params)       flash[:success] = "item updated"       redirect_to edit_item_path(@item)     else       render :edit  # line should changed     end   end

i need hash algorithm produces 64-bit hash code ( long ) fewer collisions string.gethashcode() , fast (no expensive calls cryptographic functions). here's implementation of fnv still shows 3% of collisions after testing 2 million random strings. need number way lower. void main() { const string chars = "abcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyz!#@$%^&*()_+}{\":?><,./;'[]0123456789\\"; const int n = 2000000; var random = new random(); var hashes = new hashset<long>(); int collisions = 0; for(int = 0; < n; i++) { var len = random.next(chars.length); var str = new char[len]; (int j = 0; j < len; j++) { str[j] = chars[random.next(chars.length)]; } var s = new string(str); if(!hashes.add(get64bithash( s ))) collisions++; } console.writeline("collision percentage after " + n + " random strings: " + ((doubl
