现在您大概能明白,为啥Ror的应用中,到处充斥着类似下面的调用: link_to 'Show', :action => 'show', :id => product 这里用:action而非action...= {:"0001"=>"手机",:"0002"=>"电脑"} puts products[:"0001"] 哈希参数指的其实就是在调用方法并传入参数时,可以将一个哈希表做为参数传入 def my_method...p1,p2,options={}) puts p1 puts p2 options.each{|key,value| puts "#{key} is #{value}"} end my_method...,这个写法是不是跟link_to 'Show', :action => 'show', :id => product一样时尚了 :) 题外话:哈希参数与可选参数还是有些不同的(可选参数参见"ruby学习笔记...(3)--语法层面的先见之明"),个人觉得哈希参数其实更灵活
If you use rails, then you should know how to use RSpec to test your rails app...."is invalid without a name" do # use build to skip validation, it will not call 'save' method...Delete describe 'DELETE destroy' do before(:each) do # make our test DRY @user = FactoryGirl.create...(:user) end it "deletes the user" do # note syntax, http method and rails action expect...to users#index" do delete :destroy, id: @user expect(response).to redirect_to users_url end
而GET、HEAD、PUT和DELETE请求都是幂等的,无论对资源操作多少次, 结果总是一样的,后面的请求并不会产生比第一次更多的影响。...不过很多人直接把POST、GET、PUT、DELETE直接对应上CRUD,例如在一个典型的rails实现的RESTful应用中就是这么做的。...我认为,这是因为rails默认使用服务端生成的ID作为URI的缘故,而不少人就是通过rails实践REST的,所以很容易造成这种误解。 客户端不一定都支持这些HTTP方法吧?...例如rails框架就支持通过隐藏参数_method=DELETE来传递真实的请求方法, 而像Backbone这样的客户端MVC框架则允许传递_method传输和设置X-HTTP-Method-Override...DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
