美好的一天，
请原谅我的noob问题。
在我的rails应用程序中，我有/ YYYY / MM / DD / Title-Slug URL结构，带有Friendly_Id。
news_controller.rb
class NewsController < ApplicationController
before_action :set_news, only: [:show, :edit, :update]
before_action :authenticate_user!, except: [:show, :index, :search ]
def index
if params[:search]
@news = News.search(params[:search]).paginate(:page => params[:page], :per_page => 12).order("created_at DESC")
else
@news = News.where( state: true ).paginate(:page => params[:page], :per_page => 12).order('id DESC')
end
end
def latest_news
if current_user.admin?
@news = News.paginate(:page => params[:page], :per_page => 12).order('id DESC')
else
flash[:error] = "you are not authorised to visit this section"
redirect_to root_path
end
end
def new
if current_user.state == true
@news = News.new
else
flash[:error] = "your account has not been activated"
redirect_to root_path
end
end
def show
@news_photos = @news.news_photos
end
def create
@news = News.new(news_params)
respond_to do |format|
if @news.save
if params[:images]
params[:images].each do |image|
@news.news_photos.create(image: image)
end
end
@news_photos = @news.news_photos
format.html { redirect_to show_news_path(@news.year,@news.month,@news.date,@news ), notice: 'News was successfully created.' }
format.json { render :show, status: :created, location: @news }
else
render :new
end
end
end
def edit
@news_photos = @news.news_photos
end
def update
respond_to do |format|
if current_user.admin?
if @news.update(admin_news_params)
if params[:images]
params[:images].each do |image|
@news.news_photos.create(image: image)
end
end
#redirect_to root_path, notice: "Updated..."
# redirect_to latest_news_path, notice: "Updated..."
format.html { redirect_to show_news_path(@news.year,@news.month,@news.date,@news ), notice: 'News was successfully edited' }
# format.json { render :show, status: :created, location: @news }
else
render :edit
end
else
if @news.update(news_params)
if params[:images]
params[:images].each do |image|
@news.news_photos.create(image: image)
end
end
# redirect_to news_index_path, notice: "Updated..."
#redirect_to latest_news_path, notice: "Updated..."
format.html { redirect_to show_news_path(@news.year,@news.month,@news.date,@news ), notice: 'News was successfully edited.' }
# format.json { render :show, status: :created, location: @news }
else
render :edit
end
end
end
end
def destroy
@news = News.find(params[:id])
@news.destroy
respond_to do |format|
format.html { redirect_to news_index_path }
# format.json { head :no_content }
end
end
private
def set_news
@news = News.find(params[:id])
end
def news_params
params.require(:news).permit( :title, :description, :category, :keywords, :user_id, :email, :user_name)
end
def admin_news_params
params.require(:news).permit( :title, :description, :category, :keywords, :user_id, :email, :user_name, :state)
end
end
news_helper.rb
module NewsHelper
def show_news_path(news)
"/news/#{news.year}/#{news.month}/#{news.date}/#{news.slug}"
end
end
news.rb
class News < ApplicationRecord
extend FriendlyId
include PgSearch
has_many :news_photos
friendly_id :slug_candidates, use: [:slugged, :finders, :history]
def slug_candidates
[ :title,
[:title, :id]
]
end
def year
created_at.localtime.strftime("%Y")
end
def month
created_at.localtime.strftime("%m")
end
def date
created_at.localtime.strftime("%d")
end
end
的routes.rb
Rails.application.routes.draw do
resources :news, :except => [:latest_news, :search, :show, :edit, :update]
root :to => "news#index"
scope 'news' do
get '/:year/:month/:date/:id', to: 'news#show', as: 'show_news'
get '/:year/:month/:date/:id/edit', to: 'news#edit', as: 'edit_news'
patch '/:year/:month/:date/:id', to: 'news#update'
put '/:year/:month/:date/:id', to: 'news#update'
delete '/:year/:month/:date/:id', to: 'news#destroy'
end
end
_form.html.erb
<div class="row">
<div class="col-md-8 col-md-offset-2">
<%= form_for @news, :html => { :class => 'form-horizontal', multipart: true } do |f| %>
<div class="row">
<div class="col-md-12">
<%= f.label :title, :class => 'control-label' %>
<div class="form-group">
<%= f.text_field :title, :class => 'form-control' %>
</div>
</div>
</div>
<div class="row">
<div class="col-md-12">
<%= f.label :keywords, :class => 'control-label' %>
<div class="form-group">
<%= f.text_field :keywords, :class => 'form-control' %>
</div>
</div>
</div>
<div class="row">
<div class="col-md-12">
<%= f.label :description, :class => 'control-label' %>
<div class="form-group">
<%= f.text_area :description, :class => 'form-control', id: "input" %>
</div>
</div>
</div>
<div class="row">
<div class="col-md-12">
<label>Upload Image</label>
<div class="form-group">
<span class="btn btn-success btn-file">
<i class="fa fa-cloud-upload fa-lg"></i> Upload Photos
<%= file_field_tag "images[]", type: :file, multiple: true %>
</span>
</div>
</div>
</div>
<div class="row">
<div class="col-md-6 col-md-offset-3">
<%= f.submit nil, :class => 'btn btn-info' %>
</div>
</div>
<% end %>
</div>
</div>
这是有效的：
新闻/索引
/ news / 2017/4/27 / example
什么行不通：
编辑帖子（带有表单的编辑页面将呈现，但在提交我的更改后，我收到上述错误 - 并且更改从未进入数据库）
错误：
ActionController :: RoutingError（没有路由匹配[PATCH]“/ news / example”）：
我已经完成了以下帖子以实现基于日期的slu :: /YYYY/MM/Title-Slug URL structure with Friendly_Id Solution Chokes on #edit
我不理解我在news_helper.rb中出错了什么
任何帮助都是高度赞赏的。谢谢你提前

这是因为您已禁用路线中的update操作
resources :news, :except => [:latest_news, :search, :show, :edit, :update]
解决方案是允许update从except子句中删除{<1}}
resources :news, except: [:latest_news, :search, :show, :edit]
除非他们＆＃34; view-source＆＃34;因此，对于可用性而言并不重要。

尝试以下代码：
Rails.application.routes.draw do
resources :news, :except => [:latest_news, :search, :show, :edit]
删除：从except更新
