我的控制器页面有问题.顺便说一下,我想执行localhost:3000/article/donat？author_id = 4,这意味着我想只查看带有author_id = 4的文章我试过这样的类型代码.

def donat
    @title = "All blog entries"
    if params[:author_id] == :author_id
      @articles = Article.published.find_by_params(author_id)
    else
      @articles = Article.published
    end
    @articles = @articles.paginate :page => params[:page], :per_page => 20
    render :template => 'home/index'
  end

它不起作用.你对这个案子有什么建议吗？

我尝试了以下代码,但它不起作用

class BlogsController < ApplicationController
  def index
    #@entry_pages = Paginator.new(self, Entry.count, 10, params[:page])
    @entries = Entry.find(:all,
    #:limit => @entry_pages.items_per_page,
    #:offset => @entry_pages.current.offset,
    :order => 'entries.created_at DESC',
    :include => :user)
  end
end

这是博客视图

<h1>Recently updated blogs</h1>
<% @entries.each do |entry| %>
<p>
<%= link_to entry.user.username, entries_url(:user_id => entry.user) %><br />
'<%= entry.title %>' was posted <%= time_ago_in_words(entry.created_at) %> ago
</p>
<% end %>

我希望这些项目像这样分页:

<<  [1][2][3]  >>
