Question

我试图利用废墟论坛的助手确定一个时间点。

<%= form_for @event  do |f| %>
  <%= render  shared/error_messages , :object => f.object %>
  <strong>Title</strong>
  <div class="field">
    <%= f.text_field :title  %>
  </div>
  <strong>Description</strong>
  <div class="field">
    <%= f.text_area :description, :class => "comment" %>
  </div>
  <strong>Location</strong>
  <div class="field">
    <%= f.text_field :location  %>
  </div>
  <strong>Time</strong>
  <div class="field">
    <%= select_datetime Date.today, :prefix => :start_date %>
  </div>
  <div class="actions">
    <%= f.submit "Add Event" %>
  </div>
<% end %>

In the controller I am doing this: class EventsController < ApplicationController def index @event = Event.new end

  def create
    @event = current_user.events.build(params[:event])
    if @event.save
      redirect_to root_path, :flash => { :success => "#{@event.inspect}!" }
    else
      @feed_items = []
      render  pages/home 
    end
  end
end

然而,时间从未确定......我究竟是错了吗?

Answer 1

你们需要处理你们再次被控制的人,例如:

def create
    @event = current_user.events.build(params[:event])
    datetime=DateTime.civil(params[:start_date][:year].to_i, params[:start_date][:month].to_i, params[:start_date][:day].to_i,
                            params[:start_date][:hours].to_i,params[:start_date][:minutes].to_i, params[:start_date][:seconds].to_i)
    @event.datetime = datetime
    if @event.save
      redirect_to root_path, :flash => { :success => "#{@event.inspect}!" }
    else
      @feed_items = []
      render  pages/home 
    end
  end

Answer 2

这个问题已经过去了近半年,但就在将来帮助某个人的情况下,更简单地制造具有时间归属的模型。

替换<%=选定_datetime Annual.today, :prefix => :_date %> with <%= f.datetime_select:datetime %>



And define the create action in controller as below.

def create
    @event = current_user.events.build(params[:event])
    if @event.save
      redirect_to root_path, :flash => { :success => "#{@event.inspect}!" }
    else
      @feed_items = []
      render  pages/home 
    end
end
