【问题描述】:
我是 RoR 的新手,我正在尝试构建一个 Web 应用程序。 我有一个经典应用,用户拥有 Post。
另一个模型 Online 用于将帖子放在公共墙上,它与表示可用件的嵌套表单 Orders 相关联。
所以现在,我正在尝试在我的帖子显示视图中使用“已采取”的操作来更新订单,但是 rails 说他找不到带有 'id'= 的帖子,并且使用了在线设置的私有方法,该方法正在工作创建订单。 (照片)
在线控制器:
class OnlinesController < ApplicationController
before_action :authenticate_user!
before_action :set_post
before_action :owned_online, only: [:new, :update]
before_action :set_online, except: [:taked]
before_action :set_unline, only: [:taked]
def new
@online = current_user.onlines.build
@online.post_id = @post.id
@online.user_id = current_user.id
end
def edit
end
def taked
@online.orders.update(taked: false, taked_at: Time.zone.now, taked_by: current_user)
end
def create
if Online.where(post_id: params[:post_id]).any?
@online = Online.where(post_id: params[:post_id]).last.update_attributes(push: false)
end
@online = @post.onlines.create(online_params)
if @online.save
if @online.portion <= 0
@online.update(push: false)
flash[:success] = 'Veuillez indiquer le nombre de parts disponibles '
redirect_to root_path
else
@online.update(pushed_at: Time.zone.now)
@online.update(push: true)
flash[:success] = 'Votre post est en ligne !'
redirect_to root_path
end
else
render 'new'
end
end
def update
if @onlines.update(online_params)
if @online.push == false
if @online.portion <= 0
@online.update(push: false)
flash[:success] = 'Veuillez indiquer le nombre de parts disponibles '
redirect_to root_path
else
@online.update(push: true)
flash[:success] = 'Votre post a bien été pushé !'
redirect_to root_path
end
end
else
@user.errors.full_messages
flash[:error] = @user.errors.full_messages
render :edit
end
end
private
def online_params
params.require(:online).permit(:user_id, :post_id, :prix, :portion, :push, :pushed_at, orders_attributes: [:id, :taked, :taked_at, :taked_by, :validated_at, :validated_by, :_destroy])
end
def owned_online
@post = Post.find(params[:post_id])
unless current_user == @post.user
flash[:alert] = "That post doesn't belong to you!"
redirect_to :back
end
end
def set_post
@post = Post.find_by(params[:post_id])
end
def set_online
@post = Post.find(params[:post_id])
@online = Online.find_by(params[:id])
end
def set_unline
@online = Online.find_by(params[:id])
end
end
class Online < ActiveRecord::Base
belongs_to :post
belongs_to :user
has_many :orders
accepts_nested_attributes_for :orders, allow_destroy: true
scope :push, ->{ where(push: true).order("pushed_at DESC") }
end
查看/帖子/节目:
<div class="btn-group" role="group" aria-label="...">
<%= link_to '- Pusher - ', new_post_online_path(@post), data: { confirm: 'Confirmer la mise en ligne de #{@title}?' }, class: "btn btn-primary " %>
<div class="col-md-9">
<h3>Parts :</h3>
<div id="Orders">
<ul>
<%- @post.onlines.each do |online| %>
<%- online.orders.each do |order| %>
<%- if order.taked == false %>
<li>
<%= link_to 'Take', taked_online_path(online), method: :update, class: "btn btn-warning"%>
</li>
<%end%>
<%end%>
<%end%>
</ul>
</div>
</div>
还有路线:
Rails.application.routes.draw do
get 'profiles/show'
mount RailsAdmin::Engine => '/admin', as: 'rails_admin'
devise_for :users, :controllers => { registrations: 'registrations' }
resources :posts do
resources :comments
resources :onlines do
resources :orders
end
end
get ':pseudo', to: 'profiles#show', as: :profile
get ':pseudo/edit', to: 'profiles#edit', as: :edit_profile
patch ':pseudo/edit', to: 'profiles#update', as: :update_profile
put 'online/:id/taked', to: 'onlines#taked', as: :taked_online
root 'posts#index'
所以,如果您对此有任何建议,我会接受的! 谢谢
【问题讨论】:
-
您究竟从哪里得到这个
Couldn't find Post with 'id'=错误? -
进入我的在线控制器,在私有方法中
-
我认为问题出在那一行: 但我不知道t 找到如何更新属性
-
你能用完整的错误堆栈和服务器日志中生成的参数来更新你的问题吗?
-
我给你一张错误页面的图片,上面有所有信息,以及我忘记的路线
