main:Object 的未定义方法复数 [英] undefined method pluralize for main:Object

问题描述

我正在尝试在我的控制台中测试一个方法，但即使是基本的复数形式 -

I'm trying to test a method in my console, but even the basic pluralize -

pluralize(1, 'person')

行不通..

输出:

NoMethodError: undefined method 'pluralize' for main:Object
from (pry):42:in '<main>'

但是 helper.method(:pluralize) 显示我: Method: ActionView::Base(ActionView::Helpers::TextHelper)#pluralize

我错过了什么?

推荐答案

默认情况下，控制台中不包含帮助程序.您可以先包含它们，它会起作用:

The helpers aren't included by default in the console. You can include them first and it'll work:

>> include ActionView::Helpers::TextHelper
>> pluralize(1, 'person')
# => "1 person"

或者，您可以使用 Rails 在控制台中为您提供的 helper 对象:

Or, you can use the helper object which Rails gives you in the console:

>> helper.pluralize(1, 'person')
# => "1 person"
