内部服务器错误：#<String:0x0000000589bde0> 的未定义方法“symbolize_keys”

Question

我讨厌问一个看起来已经被问过很多次的问题，但我的情况似乎有所不同。我使用 nitrous.io 作为我的开发环境，当我尝试预览我的应用程序时，我收到此错误消息。

跟踪是： 错误 NoMethodError：未定义的方法 symbolize_keys' for #<String:0x0000000476d9b0>

我想我的密钥有问题，但我不知道是什么问题。我什至不知道还有什么其他信息可以放在这里！

如果有人有任何想法，我会很感激您的意见。 . .

Answer 1

SPACE - 您的问题是缺少空格字符。

WRONG: secret_key_base:afcb44c
CORRECT: secret_key_base: afcb44c

检查你的 config/secrets.yml，它应该是这样的：

# Be sure to restart your server when you modify this file.

# Your secret key is used for verifying the integrity of signed cookies.
# If you change this key, all old signed cookies will become invalid!

# Make sure the secret is at least 30 characters and all random,
# no regular words or you'll be exposed to dictionary attacks.
# You can use `rake secret` to generate a secure secret key.

# Make sure the secrets in this file are kept private
# if you're sharing your code publicly.

production:
  secret_key_base: 59834597551c797b02cd5bb3edd7439f7a9c604bc82531d51d6e5f995e6ea849deb545df53213c5fd2ce4d698edfca65c8aa1b4e0fbadd884efefae0348b079b

development:
  secret_key_base: aea4705f645128e053daf1f8511014aca3b1e28323c3ece75f228540fb310869a6c4aeac172783d1c5c8ec9c5fe9b7f7af9a0204714db29e1d2a6709fca65ebf

test:
  secret_key_base: afcb44cfa8eab1f23d19b87e327d0fcc42e7c1d2c681812b346b57901ddb2511ebde569a1b868da367e2de14554c648f723a30de3daada015bbd0b268beeda3b

# Do not keep production secrets in the repository,
# instead read values from the environment.
# production:
#   secret_key_base: <%= ENV["SECRET_KEY_BASE"] %>

另外，如果您需要生成新密钥，请使用以下命令：rake secret

所以请不要忘记在“：”之后添加一个空格。

symbolize_keys 方法是一种期望请求具有Hash 数据类型的方法，但您的请求却具有string。所以仔细检查你的代码。
