未初始化的初始化器常量 [英] Uninitialized initializer constant

问题描述

我在initializers文件夹下创建了一个settings.rb文件，其中包含我需要在应用程序启动时初始化的值。然而，在运行轨道上，我得到了一个未初始化的内存设置（NameError）

Settings.rb

  Settings.defaults [：single_phase] = 500 
 Settings.defaults [：three_phase] = 300 
  

我已经创建了迁移，并且已经和视图一起使用了。

问题在哪里？
<在初始化器运行的时候，他们无法访问模型（是模型吗？）。

 设置= {} 
设置[ ：single_phase] = 500 
  

但是我觉得像 figaro gem可能对您正在尝试做的事有帮助。

您还可以添加任意设置在application.rb和环境文件中。

I created a settings.rb file under the initializers folder containing values I need initialized once the application starts. However, on running rails s I get a "Uninitialized contant Settings(NameError)

Settings.rb

Settings.defaults[:single_phase] = 500
Settings.defaults[:three_phase]  = 300

I created the migration to accompany it already and the view.

Where is the problem?

解决方案

At the time initializers run they do not have access to the model (is it a model?).

If it isn't a model, you can do the following:

SETTINGS = {}
SETTINGS[:single_phase] = 500

However I feel like the figaro gem might be helpful for what you are trying to do.

You can also add arbitrary settings in the application.rb and environment files.
