错误，当我尝试去calendars_path（零不能强迫Fixnum对象）

Question

我已经成功解决该问题无不能强迫Fixnum对象，但我得到另一个:(

没有给出块（产率）

我知道问题是上的index.html线8，但我不知道来解决它

模块CalendarHelper

def calendar(date = Date.today, &block) 
     Calendar.new(self, date, block).table 
    end 

class Calendar < Struct.new(:view, :date, :callback) 

    HEADER = %w[Monday Mardi Mercredi jeudi Vendredi Samedi Dimanche] 
    START_DAY = :monday 

    delegate :content_tag, to: :view 

    def table 
     content_tag :table, class: "calendar" do 
      header + week_rows 
     end 
    end 

    def header 
     content_tag :tr do 
      HEADER.map { |day| content_tag :th, day }.join.html_safe 
     end 
    end 

    def week_rows 
     weeks.map do |week| 
      content_tag :tr do 
       week.map { |day| day_cell(day) }.join.html_safe 
      end 
     end.join.html_safe 
    end 

    def day_cell(day) 
     content_tag :td, view.capture(day, &callback), class: day_classes(day) 
    end 

    def day_classes(day) 
     classes = [] 
     classes << "today" if day == Date.today 
     classes << "notmonth" if day.month != date.month 
     classes.empty? ? nil : classes.join(" ") 
    end 

    def weeks 
     first = date.beginning_of_month.beginning_of_week(START_DAY) 
     last = date.end_of_month.end_of_week(START_DAY) 
     (first..last).to_a.in_groups_of(7) 
    end 
end 

端

CONTROLER calendars_controller.rb

def index 
    @content_calendars = Calendar.all 
    @content_calendars_by_dates = @content_calendars.group_by(&:published_on) 
    @date = params[:date] ? Date.parse(params[:date]) : Date.today 
    end 


    def show 
    @calendar = Calendar.find(params[:id]) 
    end 

的index.html

1  <%= calendar @date do |date| %> 
2  <%= date.day %> 
3 
4 <!--# <%= debug(params) if Rails.env.development? %> 
5  --><% if @content_calendars_by_dates[date] %> 
6   <ul> 
7   
8   <% @content_calendars_by_dates[date].each do |article| %> 
9    <li><%= link_to calendar.event, article %></li> 
10   <% end %> 
11   
12   </ul> 
13  <% end %> 
14  <% end %>
