mongodb - 路径 "doctrine_mongodb.connections"的类型无效。需要数组，但得到字符串

Question

我对编码和这个网站还很陌生，所以我对我会犯和/或不会犯的错误感到抱歉。

我正在尝试为 mongoDB 生成 setter 和 getter(使用 symfony 3)，但是当我在控制台中输入时

php C:\wamp64\www\test\app\console doctrine:mongodb:generate:documents MainBundle

我收到此错误:

[Symfony\Component\Config\Definition\Exception\InvalidTypeException]                  
  Invalid type for path "doctrine_mongodb.connections". Expected array, but got string

注意到有关 yml 层次结构和缩进的主题，但找不到正确的答案。正如我所说，我很新，不太了解这个系统是如何工作的，所以如果有人有任何想法可能是这里的问题，请与我分享。 这是我的 config.yml 文件:

Answer 1

您缺少 2 个空格缩进:

doctrine_mongodb:
  connections: default
  default: # <-- here
      server: mongodb://localhost:27017
      options: {}

并且您不需要为 connections 指定 default 值，如下所示: connections: default 但它应该是一个数组.

所以有效的配置应该是:

doctrine_mongodb:
  connections:
    default: # <-- indentation added here
      server: mongodb://localhost:27017
      options: {}
  default_database: test_database
  document_managers:
    default:
      auto_mapping: true

参见configuration reference .

此外，我发现您在配置文件的 3/4 中使用了 4 个空格缩进。我建议您在文件中的所有位置使用相同的缩进，这样您将来就不会遇到任何麻烦，而且结构看起来会更加一致。
