我对 Rails 完全陌生,我不知道为什么会出现此错误:
undefined local variable or method `with' for ApplicationController:Class
路由:
root 'home#index'
控制器:
class HomeController < ApplicationController
def new
end
def index
end
end
应用程序跟踪:
app/controllers/application_controller.rb:4:in `<class:ApplicationController>'
app/controllers/application_controller.rb:1:in `<top (required)>'
app/controllers/home_controller.rb:1:in `<top (required)>'
我更新了一些模型和 rspec 代码来测试模型验证,但除此之外我没有创建其他控制器/视图/路由等。
注意:红宝石 2.0.0,轨道 4.0.0
应用控制器:
class ApplicationController < ActionController::Base
# Prevent CSRF attacks by raising an exception.
# For APIs, you may want to use :null_session instead.
protect_from_forgery with::exception
end
也许是某种宝石吓坏了?
