[英]How do you mixin a module into a Rails 3 controller
I have a module 我有一个模块
module Foo
def normalize name
# modify and return
end
end
I can mix it in to a model just fine... 我可以将它混合到一个模型中就好了......
class Something
include Foo
end
Something.new.normalize "a string" # works
And try to mixin to a controller... 并尝试混合到控制器......
class SomeController < ApplicationController
include Foo
def some_action
normalize "a string"
end
end
SomeController#some_action # Works in a functional test, but not within rails server! SomeController#some_action#在功能测试中工作,但不在rails服务器中!
I've tried various forms of the module, extending ActiveSupport::Concern, adding an included block and changing normalize to a class method, but I get the same results. 我已经尝试了各种形式的模块,扩展了ActiveSupport :: Concern,添加了一个包含的块并将normalize更改为类方法,但我得到了相同的结果。 Why would this work in a functional test, but not outside of it?
为什么这会在功能测试中起作用,但不能在它之外?
I get the feeling I'm just missing something easy. 我感觉我只是错过了一些简单的事情。
The reason it "worked" in the test was that the test also included the module and invoked the normalize method: 它在测试中“工作”的原因是测试还包括模块并调用normalize方法:
class SomeControllerTest < ActionController::TestCase
include Foo
which made it available to the controller... somehow. 这让它可以提供给控制器...不知何故。
Removing the include Foo made the test fail as well. 删除include Foo也使测试失败。
To make the controller work, I changed 为了使控制器工作,我改变了
normalize "a string"
to 至
self.normalize "a string"
