ruby on rails drawing failed but how come -

in below code, trying draw bunch of chart. database has model person have attribute of "name,weight,height,color,age" objective draw chart each row, weight x-axis, height y-axis. , color color each chart, eg person 1 have color yellow, chart should yellow (this tricky implmented)

anyway, using lazy_high_chart implement this, no luck, failed no error.

but consistent, here comes code: people_controller.rb

class peoplecontroller < applicationcontroller     #get /people/index     #get /people     def index         @people = person.all     end      #get /people/show/id     def show         @person = person.find(params[:id])     end      #get /people/new     def new         @person = person.new     end      #post /people/update     def create         @person = person.new(person_params)         @person.save         redirect_to :action => :index     end      #get /people/edit/:id     def edit         @person = person.find(params[:id])     end      #post /people/update/:id     def update         @person = person.find(params[:id])         @person.update(person_params)         redirect_to :action => :show, :id => @person     end      #get /people/destroy/:id     def destroy         @person = person.find(params[:id])         @person.destroy         redirect_to :action => :index     end      def display         @people = person.all         names = []         weights = []         heights = []         colors = []         ages = []         @people.each |x|             names = x.name             weights = x.weight             heights = x.height             colors = x.color         ages = x.age         end          @chart = lazyhighcharts::highchart.new('graph') |x|             x.title(:text => "display data")             x.xaxis(:categories => weights, :title => names, :margin => 10)             x.yaxis(:categories => heights)             x.series(:type => 'column', :name => 'showing data', :data => weights, :color => colors)         end     end      private     def person_params         params.require(:person).permit(:name, :weight, :height, :color, :age)     end end 

routes.rb

rails.application.routes.draw   root 'people#index'   match ':controller(/:action(/:id(.:format)))', :via => :all end 

index.html.erb:

<h1> people list</h1> <table>     <thead>         <tr>             <th>name</th>             <th> weight</th>             <th> height</th>             <th> color</th>             <th> age</th>             <th colspan="4"></th>         </tr>     </thead>     <tbody>         <% @people.each |e| %>         <tr>             <td><%= e.name %></td>             <td><%= e.weight %></td>             <td><%= e.height %></td>             <td><%= e.color %></td>             <td><%= e.age %></td>             <td><%= link_to 'show', :controller => "people", :action => "show", :id => e %></td>             <td><%= link_to 'edit', :controller => "people", :action => "edit", :id => e %></td>             <td><%= link_to 'delete', :controller => "people", :action => "destroy", :id => e %></td>         </tr>         <% end %>      </tbody>  </table>  <br> <%= link_to 'new input', :controller => 'people', :action => 'new' %> <%= link_to 'display', :controller => "people", :action => "display" %> 

display.html.erb:

<h1> display result</h1> <%= high_chart("display_res", @chart) %> 

i believe routes correct, should deal display action within controller code block. have read through lazy_high_chart example, seems simple , not related case. ideas? many thanks

yeah works out no data shown how come?? log updated, seems data extracted did not show up

you have infinite redirect. /people/display redirects /people/display.

remove line:

redirect_to :action => :display

you overwriting arrays in @people.each loop. instead of = should using << add values each array:

    names = []     weights = []     heights = []     colors = []     ages = []     @people.each |x|         names << x.name         weights << x.weight         heights << x.height         colors << x.color         ages << x.age     end
