ActionView :: Template :: Error：未定義的方法`拆分'爲零：NilClass

Question

我得到上述錯誤。我找不到解決方案。請告訴我。

這是我的feed_view_mobile.erb代碼;

if params[:controller]=='categories' 
    meta :title => " #{feed_hash[:filter_keyword]+' | ' if feed_hash[:filter_keyword].present?} " + (feed_hash[:seo_title]||feed_hash[:title]) + (((' - Page ' + params[:page]) if params[:page].present?) ||''), 
    :description => " #{feed_hash[:filter_keyword]+' | ' if feed_hash[:filter_keyword].present?} " + (feed_hash[:description] || '') + (((' - Page ' + params[:page]) if params[:page].present?) ||''), 
    :keywords => (feed_hash[:filter_keyword].split.select{ |x| x.length>2}).concat(feed_hash[:keywords] || feed_hash[:title].split.select{ |x| x.length >2 }) 
    #salwar special case for testing. 
    @secondary_message = "<a class='btn btn-primary btn-attn' href='"+new_user_registration_path.to_s+"'>Signup </a>" + " and get your free personal stylist." if !current_user.present? && params[:term]!="salwars-churidars" 
    @secondary_message = "" 
end

feed [：filter_keyword]或filter [：title]似乎都是零。

檢查你是如何設置這些值，或處理他們可能無法使用方法嘗試的情況。
