Problem - getting a nil object in view?

Hello All,

I am new to ruby programming, Problem is -

In my controller -

I defined a private method like :private def _list(searchBy, moreResults = false)

# another code goes here................. @items_by_language = {}       @items.each do |item|         @items_by_language[item.language]= if @items_by_language[item.language] == nil         @items_by_language[item.language] << item       end

end

# This @items_by_language is a hash which I am accessing in my view named list.html.erb But I get following error NoMethodError in Home#list

Showing home/list.html.erb where line #6 raised:

You have a nil object when you didn't expect it! You might have expected an instance of Array. The error occurred while evaluating nil.each

Extracted source (around line #6):

list.html.erb code -----------------------

<%@items_by_language.each do |key,val|%> <%val.each do |items|%>

//////code performed on @items_by_language hash variable

<%end%> <%end%>

list.html.erb code -----------------------

<%@items_by_language.each do |key,val|%> <%val.each do |items|%>

//////code performed on @items_by_language hash variable

<%end%> <%end%> ------------------------------------------------------------------------ In controller "_list method" is private and I want it private . Thats why it is not allowed me to access @items_by_language.

method visibility has nothing to do with instance variables. If you are going to localhost:3000/some_controller/list then your _list method is probably not even being called.
