我的应用程序允许用户搜索许多不同的字段和日期以查找项目记录。目前，当您选择某个时间尺度时，即（从现在开始的 1 年），搜索会正确返回。当您使用相同的时间尺度和某些客户端再次搜索时，搜索会再次正确返回。当我尝试仅在客户端上搜索时，问题就出在此处。搜索没有返回结果，这是错误的。我确定这与我在搜索方法中的运算符有关：

def self.search(search_client, search_start_date_dd, search_start_date_A, search_start_date_B,  search_keywords) 
  return scoped unless search_client.present?  || search_start_date_dd.present?  || search_start_date_A.present?  || search_start_date_B.present?  || search_keywords.present?


todays_date = DateTime.now.to_date

if !search_start_date_A.blank? or !search_start_date_B.blank?
    search_start_date_A = Date.parse(search_start_date_A).strftime("%Y-%m-%d")
    search_start_date_B = Date.parse(search_start_date_B).strftime("%Y-%m-%d")
    todays_date = ""
    end

if search_start_date_dd.blank?
    todays_date = ""
end




  where(['client LIKE ? AND (DATE(start_date) BETWEEN ? AND ? OR DATE(start_date) BETWEEN ? AND ?) AND keywords LIKE ?', 
      "%#{search_client}%", search_start_date_dd, todays_date , search_start_date_A, search_start_date_B, "%#{search_keywords}%"
    ])

end

我确定问题出在'client LIKE ? AND (DATE(start_date) BETWEEN ? AND ? OR DATE(start_date) BETWEEN ? AND ?) AND keywords LIKE ?'

希望有人能看到。提前致谢。只是为了让你知道我也是一个 Rails 菜鸟 :)

编辑：

这是我的搜索视图，因此您了解搜索的工作原理：

<h1>Search</h1>

<%# if @project_search.total_entries > 0 %>
<%= form_tag search_path, method: :get do %>

Client :
<%= select(@projects, :client, Project.all.map {|p| [p.client]}.uniq, :prompt => "-Any-", :selected => params[:client]) %></br>


Select start dates from:
<%= select_tag "start_date_dd", options_for_select({
    "Select a period" => "",
      "3 days ago"   => DateTime.now.to_date - 3.days,   # =    259_200 sec.
      "1 week ago"   => DateTime.now.to_date - 1.week,   # =    604_800 sec.
      "1 month ago"  => DateTime.now.to_date - 1.month,  # =  2_592_000 sec.
      "6 months ago" => DateTime.now.to_date - 6.months, # = 15_552_000 sec.
      "1 year ago"   => DateTime.now.to_date - 1.year,   # = 31_557_600 sec.
    }, :selected=>params[:start_date_dd] )%>

until now <%= l DateTime.now.to_date %>, or select project start dates between

<%=  text_field_tag :start_date_A, params[:start_date_A] %>

and

<%=  text_field_tag :start_date_B, params[:start_date_B] %>

Keywords :

<%= text_field_tag :keywords, params[:keywords] %></br>

<%= submit_tag "Search", name: nil %>

修复了我自己的问题：/

我刚刚添加了一个其他

def self.search(search_client, search_start_date_dd, search_start_date_A, search_start_date_B,  search_keywords) 
  return scoped unless search_client.present? || search_start_date_dd.present?  || search_start_date_A.present?  || search_start_date_B.present?  || search_keywords.present?


todays_date = DateTime.now.to_date

if !search_start_date_A.blank? or !search_start_date_B.blank?
    search_start_date_A = Date.parse(search_start_date_A).strftime("%Y-%m-%d")
    search_start_date_B = Date.parse(search_start_date_B).strftime("%Y-%m-%d")
    todays_date = ""
    end

if search_start_date_dd.blank?
    todays_date = ""
end


if (search_start_date_A.blank? or search_start_date_B.blank?) and search_start_date_dd.blank?

where(['client LIKE ? AND keywords LIKE ?', 
      "%#{search_client}%", "%#{search_keywords}%"
    ])

else

where(['client LIKE ? AND (DATE(start_date) BETWEEN ? AND ? OR DATE(start_date) BETWEEN ? AND ?) AND keywords LIKE ?', "%#{search_client}%", search_start_date_dd, todays_date , search_start_date_A, search_start_date_B, "%#{search_keywords}%"
    ])
end
end
