我试图查找两个约会时间之间的“事件”

    if (params[:timeMin].present? and params[:timeMax].present?)
      @events = Event.where('date > ? AND date < ?', params[:timeMin], params[:timeMax])

我不断遇到类似的错误，我不知道如何修复它

SQLite3::SQLException: near ",": syntax error: SELECT "events".* FROM "events"  WHERE (date > '---
- (1i)
- ''2014''
','---
- (2i)
- ''1''
','---
- (3i)
- ''8''
','---
- (4i)
- ''14''
','---
- (5i)
- ''36''
' AND date < '---
- (1i)
- ''2014''
','---
- (2i)
- ''1''
','---
- (3i)
- ''13''
','---
- (4i)
- ''14''
','---
- (5i)
- ''36''
') ORDER BY events.created_at DESC

这是导致视图中出现问题的行

<% @events.each do |event| %>

谢谢

请求的信息

index.html.erb

<%= form_tag events_path, :method => :get do %>
  <p>
    <%= text_field_tag :search, params[:search] %>
    <%= datetime_select :timeMin, params[:timeMin] %>
    <%= datetime_select :timeMax, params[:timeMax] %>
    <%= submit_tag "Search Near", :name => nil %>
  </p>
<% end %>

使用@CDub的解决方案

当发出日期应为2的请求时记录所有事件->无返回空列表

您正在返回需要解析为字符串的datetime_select哈希。一种方法是执行以下操作：

min_hash = params[:timeMin]
max_hash = params[:timeMax]

min_time_string = "#{min_hash['(1i)']}-#{min_hash['(2i)']}-#{min_hash['(3i)']} #{min_hash['(4i)']}:#{min_hash['(5i)']}:#{min_hash['(6i)']}"

max_time_string = "#{max_hash['(1i)']}-#{max_hash['(2i)']}-#{max_hash['(3i)']} #{max_hash['(4i)']}:#{max_hash['(5i)']}:#{max_hash['(6i)']}"

在此解析之后，应该可以执行以下操作：

@events = Event.where('date > ? AND date < ?', min_time_string, max_time_string)

添加了timeMin和timeMax来自的表单。希望这会有所帮助。尝试在railsThanks中找出模型搜索以获得帮助，但仍然存在问题。1如果我设置了它应该选择事件的日期，它将运行并且不返回任何事件列表为空。2如果我不更改日期min==max，它将返回一个错误页面请求-URI太大。任何想法都不确定我是否遵循问题1…这两个问题的日志是什么样子的？发布日志。是否可以查看每个modelSure的当前“日期”确定。您可以将其粘贴在Rails.logger.info调用中，并将其打印到日志中。我还更新了我的答案-没有6i。我还使用了date.parse来实际执行我会生成一个合法的日期对象。试试看。
