ruby - Calling a method in the view controller Rails -

to generalize problem, using api returns iterable object. within id each object. controller looks this:

class searchcontroller < applicationcontroller     def index         @search = api.find(params[:query])     end end 

my view this:

    <% @search.each |thing| %>         <h2><%= thing.attr2 if thing.attr1 %></h2>         <%= api.list(thing.attr2) %>     <% end %> 

i have tried adding method

class searchcontroller < applicationcontroller     def index         @search = api.find(params[:query])              def getlist(attr2)                 api.list(thing.attr2)             end        end end 

and adding index , self before definition (ex: self.getlist(attr2)) , calling in variations in view:

<%= getlist(thing.attr2) %> 

i wondering going wrong here. have additionally tried add in helper_method line read in few docs not recognize it. also, correct way go style-wise? having hard time finding references makes me think isn't standard practice.

the method trying make helper method, , therefore, needs go in helper method controller.
