WordPress to Rails (5) static pages

WordPress lumps posts and static pages together in one database table, but they need to be handled quite differently.

At least for the time being, I’m leaving them in the same table.

First, in the Post model, a different permalink is needed for static pages and for posts:

def permalink
  if post_type == 'page'
    post_name
  else
    post_date.strftime("%Y/%m/%d") + (post_name.empty? ? '' : "/#{post_name}")
  end
end

Then, also in the Post model, I have several scopes:

scope :published_posts, where(:post_status => 'publish', :post_type => 'post').order('post_date DESC')
scope :published_pages, where(:post_status => 'publish', :post_type => 'page')
scope :pages, where(:post_type => 'page')
scope :not_pages, where('post_type != page')

Then two different methods to find posts, depending on whether the user is logged in or not (see below):

def self.find_by_permalink(permalink)
  if permalink !~ /\//
    pages.find(:first, :conditions => ["post_name = ?", permalink])
  else
    year, month, day, name = permalink.split('/')
    name ||= ''
    not_pages.find(:first, :conditions => ["YEAR(post_date) = ? AND MONTH(post_date) = ? AND DAYOFMONTH(post_date) = ? AND post_name = ?", year.to_i, month.to_i, day.to_i, name])
  end
end

def self.find_published_by_permalink(permalink)
  if permalink !~ /\//
    published_pages.find(:first, :conditions => ["post_name = ?", permalink])
  else
    year, month, day, name = permalink.split('/')
    name ||= ''
    published_posts.find(:first, :conditions => ["YEAR(post_date) = ? AND MONTH(post_date) = ? AND DAYOFMONTH(post_date) = ? AND post_name = ?", year.to_i, month.to_i, day.to_i, name])
  end
end

Then, in PostController, the show method becomes a bit more advanced (or messy):

def show
  # Show all posts if logged in, otherwise restrict to published posts
  if User.find_by_ID(session[:user_id])
    @post = Post.find_by_permalink(params[:id]) || not_found
  else
    @post = Post.find_published_by_permalink(params[:id])
    if not @post
      # Check if post _would_ be visible if logged in; ask to log in if so
      if Post.find_by_permalink(params[:id])
        session[:return_to] = request.url
        redirect_to login_url, :notice => "Please log in"
        return
      else
        not_found
      end
    end
  end
  ...
end

The not_found method is in ApplicationController (see here):

def not_found
  raise ActionController::RoutingError.new('Not Found')
end

routes.rb needs to be changed, to route (say) .../about to the appropriate page, with the following line going after all the other routing information (but before the root statement):

resources :posts, :only => [:show, :update, :destroy, :edit], :path => '', :id => /\d{4}\/\d{2}\/\d{2}(\/[0-9a-z\-_]+)?|[0-9a-z\-_]+/

And there are some changes to the post view, to hide details that are not relevant to static pages (such as date and comments).
