RSpec控制器测试嵌套强参数

我可能会也可能不会发现RSpec代码中的错误，它在使用accep_nested_attributes_for时不会根据需要发布嵌套属性。RSpec控制器测试嵌套强参数

这里是我的控制器测试：

it 'attaches a file to document' do 
    post :create, { 
    app_id: @app1.id, 
    document: { 
     recipient_id: @app2.id, 
     delivery_service: 'default', 
     attachments_attributes: { 
     0 => { 
      attachment: fixture_file_upload('files/document.json', 'application/json') 
     } 
     } 
    }, 
    format: 'json' 
    } 

    attachment = assigns(:document).attachments.first 
    attachment.exists?.should be_true 
    attachment.url.should match 'amazon' 
end

这里的文件控制器的强大PARAMS：

当测试职位的控制器，因为它不承认0 attachments_attributes被忽略键。但这就是属性应该如何实现的原理。

当我把0键并在测试中只留下这样的：

attachments_attributes: { 
    attachment: fixture_file_upload('files/document.json', 'application/json') 
}

我得到undefined method '[]' for Tempfile

下面是从我控制器最多的是回溯：

nested_attributes。 rb仍然期望attachments_attributes被索引，但RSpec正在做的事情不会让它通过强大的参数。也许它只是通过散列而不是浏览器的查询字符串？我会继续挖掘。

有没有其他人处理过这个？谢谢！

好吧伙计......我的宝贝。

属性必须被字符串索引。因此，而不是：

attachments_attributes: { 
    0 => { 
     attachment: fixture_file_upload('files/document.json', 'application/json') 
    } 
    }

我不得不这样做：

attachments_attributes: { 
    "0" => { 
     attachment: fixture_file_upload('files/document.json', 'application/json') 
    } 
    }

所以啊。 0应该是“0”。没有发现错误。我现在去坐在角落里。
