问题描述

Symfony2 WebProfiler（500）：由于数组在209行的@ Doctrine / Collector / db.html.twig中为空，因此键默认不存在

Symfony2 WebProfiler (500): Key "default" does not exist as the array is empty in @Doctrine/Collector/db.html.twig at line 209

我已经在几台机器（php 5.4，php 5.5）上安装了Sonata e-commerce 2.3分支（全新安装），一切正常，但是在每台机器上，我在探查器学说DB选项卡中都有相同的错误：

I have installed Sonata e-commerce 2.3 branch (fresh installation) on several machines (php 5.4, php 5.5), everything works fine, but and on each one i have the same error in profiler doctrine DB tab:

Symfony2 WebProfiler (500): Key "default" does not exist as the array is empty in @Doctrine/Collector/db.html.twig at line 209

Profiler仅在第一个请求后（缓存为空）工作正常，下一个请求后错误。
我正在网上寻找解决方案，但没有成功。.

Profiler is working fine only after first request (when cache is empty), after the next request there is the error. I was searching the web for the solution, but without success..

预先感谢

推荐答案

您可以自己覆盖@ Doctrine / Collector / db.html.twig模板。只需添加条件如果在第209行的新模板中定义了collector.mappingErrors [manager] 即可。

You can override @Doctrine/Collector/db.html.twig template by your own. Just add condition if collector.mappingErrors[manager] is defined in your new template on line 209.
