Rails连接表上的路由和模型问题

我正在创建一个应用程序,允许用户为我附近的地方创建自定义行程。每个地方都存储在一个位置表中,并与place_id相关联。目前,这些地方通过行程作为连接表与用户相关联。这工作正常,但我想允许用户sign_in并被定向到一个列出所有行程的视图。为此,我需要通过一组具有标题并与user_id相关联的用户参数创建行程的新实例。然后,用户可以将place_ids添加到该行程的实例中。不幸的是,我无法理解这应该如何在活动记录中进行路由。任何人都可以帮我弄清楚如何构建它,所以它会工作,因为我尝试的一切都会返回错误:没有路由匹配[GET]" / create_itinerary"。

行程模型

class Itinerary < ApplicationRecord
belongs_to :user
belongs_to :place

行程控制器

class ItinerariesController < ApplicationController
def add_place
    # current_user
    @place = Place.find(params[:id])
    @itenerary = @place.itineraries.create(user_id: current_user.id)

    redirect_to :back
end

def index
    @itinerary_places = current_user.places
end

def show
    @itinerary_places = current_user.places
end

def new
    @itinerary_new = Itinerary.new(params[:itinerary])

    redirect_to create_itinerary_path
end

def create
    itinerary = Itinerary.new(itinerary_params)
    itinerary.user_id = session[:user_id]
    itinerary.save
end

private

def itinerary_params
    params.require(:itinerary).permit(:title)
end

    end

行程(new.html.erb)

<%= form_for @itinerary_new, url: {action: "create"}, html: {} do |f| %>

<%= f.text_field :title, placeholder: "Name Your New Itinerary" %>

<%= f.submit :class => "user_submit" %>

行程路线

get "/itinerary_new", to: "itineraries#new"
get "/itinerary_portal", to: "itineraries#index"
get "/itinerary", to: "itineraries#show"
get "/add_place/:id", to: "itineraries#add_place"
get "/delete_itinerary", to: "itineraries#destroy"
post "/create_itinerary", to: "itinerary#create"

架构

ActiveRecord::Schema.define(version: 20170402040005) do

create_table "itineraries", force: :cascade do |t|
 t.integer  "user_id"
 t.datetime "created_at", null: false
 t.datetime "updated_at", null: false
 t.integer  "place_id"
 t.string   "title"

 end

问题是,当您访问/itinerary_new时,它会重定向到/create_itinerary。然后http方法不匹配,因为create_itinerary只接受post,没有get

redirect_to create_itinerary_path操作中移除new。这句话毫无意义和错误。
