有人可以帮助我举办活动日历吗？我需要一个日历，显示一个人的医疗预约和治疗（可能还有一些其他的东西）。我正在尝试实施event_calendar，但我不确定它是如何运作的。
如何建立模型（治疗和预约）与日历之间的关联？我是否必须在我要与我的日历关联的所有模型中包含has_event_calendar或其他内容？
我正在关注https://github.com/elevation/event_calendar笔记，但目前我只收到undefined method 'first' for nil:NilClass。
谢谢！

我在calendar_helper的event_calendar方法中遇到错误（在calendar event_calendar_opts do |args|行中）。
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
{
:year => @year,
:month => @month,
:event_strips => @event_strips,
:month_name_text => Time.zone.now.strftime("%B %Y"),
:previous_month_text => nil,
# :previous_month_text => "<< " + month_link(@shown_month.prev_month),
# :next_month_text => month_link(@shown_month.next_month) + " >>"
:next_month_text => nil
}
end
def event_calendar
# args is an argument hash containing :event, :day, and :options
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

_calendar.html.erb
raw(event_calendar)
答案 0 :(得分：0)
我最终决定使用fullcalendar而不是event_calendar。我不确定event_calendar和rails 4是否有问题。这是我的第一个日历，无论如何也许我做错了。
