Блог

Основная часть моего блога не отображается, когда я нажимаю на Heroku. Я перепробовал несколько способов, но безрезультатно. Я перенес базу данных. В журналах Heroku указано, что он отображает страницу, но при запуске приложения не отображается ни одна из ссылок, HTML или встроенного ruby. Я думаю, что это может иметь какое-то отношение к моей модели статей. Не уверен. Вот что у меня есть. Дайте мне знать, если вам нужно увидеть что-нибудь еще. Спасибо

     class ArticlesController < ApplicationController


  def new
    @article = Article.new
  end

  def index
    @article = Article.all


    @articles = Article.order('created_at DESC')
    @articles_by_month = Article.find(:all, :order => 'created_at DESC').group_by { |article| article.created_at.strftime("%B %Y") }
  end


  def month_count
    @articles_by_month = Article.find(:all, :order => 'created_at DESC').group_by { |article| article.created_at.strftime("%B %Y") }
  end

  def create  
    @article = Article.new(article_params)

      if @article.save
      redirect_to @article
    else
      render 'new'
    end
  end



  def edit
    @article = Article.find(params[:id])
  end

  def update
    @article = Article.find(params[:id])

    if @article.update(article_params)
      redirect_to @article
    else
      render 'edit'
    end
  end


  def show
    @article = Article.find(params[:id])
  end

  def destroy
    @article = Article.find(params[:id])
    @article.destroy

    redirect_to articles_path
  end

  private

  def article_params
    params.require(:article).permit(:title, :text, :image)
  end

end


Model

class Article < ActiveRecord::Base
  has_many :comments, dependent: :destroy
  validates :title, presence: true,
                    length: { minimum: 5 }
  mount_uploader :image, ImageUploader 
  default_scope -> { order('created_at DESC') }                 
end
  

Вот представление, которое вообще не отображается. Остальные представления (верхний, нижний колонтитулы и т.д.) Отображаются нормально, и ссылки работают.

 <div class="bit-75">

  <% @article.each do |article| %>
    <h2 id="title"><%= link_to article.title, article_path(article) %></h2>
    <br>
    <ul id="article-links">

      <br>
      <li id="article-text"><%= article.text %></li>

    <% if admin_signed_in? %>

      <li><%= link_to 'Destroy',        article_path(article),

    </ul>
    <% end %>   
  <% end %>

<div id="new-article-path"></div>
</div>
<div class="bit-5">
  <h2>Recent Posts</h2>

    <br>

  <% @article.each do |article| %>

    <ul id="recent-article">

    </ul>

  <% end %>
    <br>
    <br>

  <h2>Archives</h2>

  <% @articles_by_month.each do |monthname, articles| %>
    <h4 id="month-archive"><%=link_to monthname, archives_path %></h4>

Попытался запустить это ‘RAILS_ENV=production bundle exec rake assets: предварительная компиляция’

Получил это в терминале

 rake aborted!
Gem::LoadError: Specified 'postgresql' for database adapter, but the gem is not loaded. Add `gem 'pg'` to your Gemfile.
  

Данные

Если ваш HTML / ruby встроенный код работает для других controller#actions , у вас, вероятно, возникнут проблемы с маршрутизацией или с тем, как вы структурируете свое представление.

Я бы сделал это:

 $ heroku run rails c
$ Article.create(title: "test, body: "test")
  

Это позволит вам создать Article запись в рабочей среде, которая будет вероятной причиной вашей проблемы (отсутствие правильного набора данных)

—

Маршруты

После того, как это будет завершено, сохраните, а затем вам нужно убедиться, что вы вызываете правильный controller#action в своих маршрутах. Вы должны установить его с помощью resourceful маршрутизации:

 #config/routes.rb
resources :articles
  

—

Модель

Наконец, вы переопределили default_scope часть своей модели, но вызываете точно такие же условия при использовании

 #app/models/article.rb
Class Article < ActiveRecord::Base
   default_scope ....
end
  

Вы должны удалить default_scope ссылку — вам это не нужно

Предварительная компиляция

Причина, по которой ваша предварительная компиляция rake не работает, заключается в том, что вы не используете PG локально. Поскольку вы используете его в production .

Чтобы исправить это, вам просто нужно включить его за пределы group: production do блока в ваш routes файл:

 #Gemfile
gem 'pg' #-> allows precompile to run for production environment
