Question

我正在尝试使用event_calendar gem，我遵循这3个指南 http://andolasoft.wordpress.com/2013/01/09/how-to-implement-event-calendar-in-rails-app/ https://github.com/elevation/event_calendar#static-files https://github.com/elevation/event_calendar/wiki/Quickstart-from-scratch

我认为我的问题是关于样式表和javascript的包含。我无法理解包括的步骤，因为每个导游都说不同的东西。

继承错误

Calendar＃index中的TypeError   显示/home/user/work/aptana_1/spree_calendar/app/views/calendar/index.html.erb其中＆gt;第6行引发：

没有将nil隐式转换为Hash   提取的来源（第6行）：

     <h1>Calendar</h1>

      <%= event_calendar %>

>Rails.root: /home/user/work/aptana_1/spree_calendar
>
>Application Trace | Framework Trace | Full Trace
>app/helpers/calendar_helper.rb:24:in `event_calendar'

>Request

>Parameters:

>{"year"=>"2014",
> "month"=>"07"}

这是calendar_helper文件

module CalendarHelper
 def month_link(month_date)
    link_to(I18n.localize(month_date, :format => "%B"), {:month => month_date.month, :year => month_date.year})
  end

  # custom options for this calendar
  def event_calendar_opts
    puts("EVENTCALENDAROP")
    { 
      :year => @year,
      :month => @month,
      :event_strips => @event_strips,
      :month_name_text => I18n.localize(@shown_month, :format => "%B %Y"),
      :previous_month_text => "<< " + month_link(@shown_month.prev_month),
      :next_month_text => month_link(@shown_month.next_month) + " >>"    
      }
      puts"###{@year}"
      puts"###{:year.to_s}"
  end

  def event_calendar
    # args is an argument hash containing :event, :day, and :options
    puts "EVENT_CALENDAR"
    calendar event_calendar_opts do |args|
      event = args[:event]
      %(<a href="/events/#{event.id}" title="#{h(event.name)}">#{h(event.name)}</a>)
    end
  end 

end

这是视图

<!-- Probably move the stylesheet to you layout. Also make sure you include the javascript. -->
<%= stylesheet_link_tag "event_calendar" %>

<h1>Calendar</h1>

<%= event_calendar %>

这是应用程序布局

<!DOCTYPE html>
<html>
<head>
  <title>SpreeCalendar</title>
  <%= stylesheet_link_tag    'application', media: 'all', 'data-turbolinks-track' => true %>
  <%= javascript_include_tag 'application', 'data-turbolinks-track' => true ,'event_calendar'%>
  <%= csrf_meta_tags %>
</head>
<body>

<%= yield %>

</body>
</html>

问题出在这个方法中：

def event_calendar_opts
  puts("EVENTCALENDAROP")
  { 
    :year => @year,
    :month => @month,
    :event_strips => @event_strips,
    :month_name_text => I18n.localize(@shown_month, :format => "%B %Y"),
    :previous_month_text => "<< " + month_link(@shown_month.prev_month),
    :next_month_text => month_link(@shown_month.next_month) + " >>"    
  }
  puts "###{@year}"
  puts "###{:year.to_s}"
end

我相信最后两次调用puts是调试输出，但它们会更改#event_calendar_opts的返回值。您应该删除puts或将其移至顶部：

def event_calendar_opts
  puts("EVENTCALENDAROP")
  puts "###{@year}"
  puts "###{:year.to_s}"
  { 
    :year => @year,
    :month => @month,
    :event_strips => @event_strips,
    :month_name_text => I18n.localize(@shown_month, :format => "%B %Y"),
    :previous_month_text => "<< " + month_link(@shown_month.prev_month),
    :next_month_text => month_link(@shown_month.next_month) + " >>"    
  }
end

event-calendar rails 4不起作用
