篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了ruby on rails:undefined方法`_path'相关的知识,希望对你有一定的参考价值。
当我正在尝试创建一个新房间时,我从第7行的错误中收到错误:
undefined method `rooms_path' for #<#<Class:0x007fb46b5db2a0>:0x007fb46b5d9ec8>
我有点困惑为什么我得到这个错误。我在Room
和Facility
之间建立了一种关系,每个设施都有很多房间。 Facility部分无bug,我已经能够创建/编辑/显示设施。
意见(views / rooms / new.html.erb)
<div class="panel panel-default">
<div class="panel-heading">
Create your beautiful room
</div>
<div class="panel-body">
<div class="container">
<%= form_for @room do |f| %>
<div class="form-group">
<label>Name</label>
<%=f.text_field :room_name, placeholder: "What is the name of the room?", class: "form-control", required: true%>
</div>
<div><%= f.submit "Create This Room", class: "btn btn-normal" %></div>
<%end%>
</div>
</div>
</div>
我的房型(型号/ room.rb):
class Room < ApplicationRecord
belongs_to :facility
validates :room_type, presence: true
validates :room_name, presence: true
end
我的设施模型(models / facility.rb):
class Facility < ApplicationRecord
belongs_to :user
has_many :photos
has_many :rooms
validates :facility_name, presence: true
validates :address, presence: true
validates :license, presence: true
validates :phone, presence: true
def cover_photo(size)
if self.photos.length > 0
self.photos[0].image.url(size)
else
"blank.jpg"
end
end
end
我的房间控制器(controllers / rooms_controller.rb)
class RoomsController < ApplicationController
before_action :set_room, except: [:index, :new, :create]
def index
@facility = Facility.find(params[:facility_id])
@rooms = @facility.rooms
end
def new
@facility = Facility.find(params[:facility_id])
@room = @facility.rooms.build
end
end
路线(routes.rb)
Rails.application.routes.draw do
devise_for :users,
path: '',
path_names: {sign_in: 'login', sign_out: 'logout', edit: 'profile', sign_up: 'registration'},
controllers: {omniauth_callbacks: 'omniauth_callbacks', registrations: 'registrations'}
resources :users, only: [:show]
resources :facilities, except: [:edit] do
member do
get 'listing'
get 'pricing'
get 'features'
get 'services'
get 'types_care'
get 'photo_upload'
get 'room_upload'
end
resources :rooms, except: [:edit] do
member do
get 'listing'
get 'pricing'
get 'photo_upload'
end
end
resources :photos, only: [:create, :destroy]
end
end
被困在这几天,非常感谢帮助:)非常感谢提前!
答案
form_for
根据@room
类产生url,它不包括外部资源。因此,您必须告诉Rails使用以下语句明确地执行此操作:
<%= form_for [@room.facility, @room] do |f| %>
另一答案
当你的路线嵌套时,为form_for
而不是<%= form_for @room do |f| %>
选择以下任何一种
<%= form_for @room, url: [@room.facility, @room] do |f| %>
<%= form_for @room, url: [:facility, @room] do |f| %>
<%= form_for [@room.facility, @room] do |f| %>
<%= form_for [:facility, @room] do |f| %>
