Question

我在Blade laravel 5中进行查询时遇到问题

 @foreach($dates_chart_debit as $date)
<?php

$result =  DB::table('productions')
->join('durees', 'productions.duree_id', '=', 'durees.id')
->where(DB::raw("Date(productions.date)") ,"=",$date)
->where('productions.puit_id' ,"=",1)
->where(DB::raw("durees.isInReport") ,"=",'1')
->where('final_validation' ,"=",'1')
->select(DB::raw("sum(debit) as debit"))->first()->get();
?>

{{$result->debit}}
@endforeach

它给我一个错误信息，如

Object of class stdClass could not be converted to string (View: C:\Program Files\EasyPHP-DevServer-14.1VC9\data\localweb\projects\Coil\resources\views\panel\chart\executive.blade.php)

什么是最好的方法

Answer 1

您的问题来自$ date变量 - 您正在尝试将对象传递给查询并将其转换为字符串。

您的评论

$ dates_chart_debit的值是数组：3 [0 =＆gt; {＃235 +＆＃34; date＆＃34;：＆＃34; 2016-07-14＆＃34; } 1 =＆gt; {＃236 +＆＃34; date＆＃34;：＆＃34; 2016-07-20＆＃34; } 2 =＆gt; {＃237 +＆＃34; date＆＃34;：＆＃34; 2016-07-29＆＃34; }]

确认这一点。

如果您更换了：

from = seq(1,100, 10)
aa <- length(url)
func1 = function(url){
  out <- tryCatch(
    {
      aa <<- aa -1 
      print(aa)
      doc =  htmlParse(url)
      address= as.data.frame(xpathSApply(doc,'//div[@class="panel-body"]', xmlValue, encoding="UTF-8"))
      page =  cbind(address,url)

      if (aa %in% from){
        pg =  suppressMessages(melt(cc))
        write.csv(pg,paste("bcc_",aa,".csv"))
      }

}
cc = lapply(url, func1)

使用：

->where(DB::raw("Date(productions.date)") ,"=",$date)

有效吗？

另外 - 你能做dd（$ date）;对我来说好吗？

我使用Chart Js

当我尝试设置$ date的默认值时，它没有显示任何内容未声明HTML文档的字符编码。如果文档包含US-ASCII范围之外的字符，则对于某些浏览器配置，文档将显示不正确的字符。必须在文档或传输协议中声明编码字符页。
