mi aspettavo tASSOC in un file Rails

Question

Sono sicuro di aver fatto qualcosa di stupido qui, ma non riesco a vederlo.

Ho chiamato il metodo breadcrumb nella vista applicazione.

app/aiutanti/breadcrumbs_helper.rb dice:

module BreadcrumbsHelper 

    def breadcrumb 
    @crumb_list = [] 
    drominay_crumb_builder 
    project_crumb_builder 
    content_tag(:div, :id => "breadcrumbs", @crumb_list.map { |list_item| crumb_builder(list_item) }) 
    end 

    def crumb_builder(list_item) 
    if list_item == @crumb_list.last 
     content_tag(:span, list_item['body'], :class => list_item['crumb']) 
    else 
     body = ["list_item['body']", " → "].join 
     link_to(body, list_item['url'], :class => list_item['crumb']) 
    end 
    end 

    def drominay_crumb_builder 
    list_item = Hash.new 
    list_item['body'] = "Drominay" 
    list_item['url'] = "root" 
    @crumb_list << list_item 
    end 

    def project_crumb_builder 
    end 

end 

Perché oh perché sto ottenendo questo errore "aspetta tASSOC"? (E che cos'è un TASS comunque?)

Answer 1

tOCCO significa l'operatore =>

Answer 2

Era perché avevo gli argomenti per content_tag nell'ordine sbagliato.

Sono ancora interessato a sapere cosa sia un TASSOC, tuttavia.
