如何轨知道如何映射到每个功能的控制器，如果routes.rb文件只规定：的Rails的routes.rb
resources :users
但UsersController里面你有
class UsersController < ApplicationController
# GET /users
# GET /users.json
def index
@users = User.all
respond_to do |format|
format.html # index.html.erb
format.json { render :json => @users }
end
end
# GET /users/1
# GET /users/1.json
def show
@user = User.find(params[:id])
respond_to do |format|
format.html # show.html.erb
format.json { render :json => @user }
end
end
# GET /users/new
# GET /users/new.json
def new
@user = User.new
respond_to do |format|
format.html # new.html.erb
format.json { render :json => @user }
end
end
# GET /users/1/edit
def edit
@user = User.find(params[:id])
end
# POST /users
# POST /users.json
def create
@user = User.new(params[:user])
respond_to do |format|
if @user.save
format.html { redirect_to @user, :notice => 'User was successfully created.' }
format.json { render :json => @user, :status => :created, :location => @user }
else
format.html { render :action => "new" }
format.json { render :json => @user.errors, :status => :unprocessable_entity }
end
end
end
# PUT /users/1
# PUT /users/1.json
def update
@user = User.find(params[:id])
respond_to do |format|
if @user.update_attributes(params[:user])
format.html { redirect_to @user, :notice => 'User was successfully updated.' }
format.json { head :no_content }
else
format.html { render :action => "edit" }
format.json { render :json => @user.errors, :status => :unprocessable_entity }
end
end
end
# DELETE /users/1
# DELETE /users/1.json
def destroy
@user = User.find(params[:id])
@user.destroy
respond_to do |format|
format.html { redirect_to users_url }
format.json { head :no_content }
end
end
end
如何轨确定例如index function maps到GET/users而create function映射到POST/users？
resources :users怎么知道映射到UsersController？
