Rails `config_for` 返回一个空的哈希值

Question

I saw this question yet the solution did not work for me. As per the rails docs , I've taken the following steps:

I've created a file config/benchmarks.yml , with the following content:

Test: "This"

I also added config.benchmarks = config_for(:benchmarks) in the config/application.rb file.

I also added the path to config/spring.rb yet when I go to the console and enter Rails.application.config_for(:benchmarks) it returns an empty hash.

What am I missing here? I'm running Rails 5.2.1.

Answer 1

No need to touch config/spring.rb file. Just make sure you are passing as like in sample below.

# config/benchmarks.yml
development:
  test: test

#application.rb
config.benchmarks = config_for(:benchmarks)

#rails console
Rails.application.config_for(:benchmarks)

=> {
     "test" => "test"
   }

config_for wants to have a "section" to pull. That section is the value in Rails.env. If you just have a "flat" .yml which can be valid YML you'll get an empty set.
