Rails - 使用「namespaced」查詢db網址

Question

我有一個模型，如Trips(id:integer, from: string, to: string, date: date)。

如何設置我的路線和trips_controller爲了能夠查詢我的數據庫只是像root_path/trips/:from/:to/:date URL？

Answer 1

嘗試添加該到你的路由文件config/routes.rb：

get 'trips/:from/:to/:date', action: 'index', controller: 'trips' 

而且你的控制器看起來應該是這樣：

class TripsController < ApplicationController 
    # You can use whatever action instead of 'index' 
    def index 
    from = params[:from] 
    to = params[:to] 
    date = params[:date] # You can even parse this with Date.parse(params[:date]) 

    # Do whatever you want with those values 
    end 
end
