我正在尝试创建报告页面,用户将选择开始和结束日期并推送buttopn报告。然后隐藏的div变得可见。
我的搜索不是部分。
我正在使用jquery_datepicker所以这是我的代码来自视图:
<%= form_tag(:controller => "financial_reports", :action => "index", :method => "post")%>
<%= datepicker_input "financial_report","start_date", :dateFormat => "dd/mm/yy" %>
<%= datepicker_input "financial_report","end_date", :dateFormat => "dd/mm/yy" %>
<%= submit_tag "Run Report"%>
<% end %>
这是我来自控制器的代码:
def search
@financial_reports = current_user.financial_reports.search(params[:start_date], params[:end_date]
render :index
end
在我的模型中:
def self.search(from,to)
find(:all, :conditions => [ "BETWEEN ? AND ?", from, to])
end
它给了我错误:
ActiveRecord::StatementInvalid in FinancialReportsController#search
SELECT `financial_reports`.* FROM `financial_reports` WHERE `financial_reports`.`user_id` = 67 AND (BETWEEN NULL AND NULL)
以下:
Parameters:
{"utf8"=>"✓",
"authenticity_token"=>"AMobLLRV3aAlNn6b4Au+1nRP2AN1TLQcBCytBXhDA/g=",
"type"=>"",
"financial_report"=>{"start_date"=>"05/08/2012",
"end_date"=>"11/08/2012"},
"commit"=>"Run Report",
"method"=>"post"}
我的错误在哪里?
答案 0 :(得分:1)
如果两个参数始终都设置,您可以使用:
@financial_reports = current_user.financial_reports.where(:created_at => ((params[:start_date].to_date)..(params[:end_date].to_date))
如果不是这样,你可以(例如)这样做:
@financial_reports = current_user.financial_reports
if params[:start_date].present?
@financial_reports = current_user.financial_reports.where("created_at >= ?", params[:start_date])
end
if params[:end_date].present?
@financial_reports = current_user.financial_reports.where("created_at <= ?", params[:end_date])
end
您可能希望将其封装在范围中。
