Question

所以我正在尝试使用will_paginate-rails3并且它在我的控制器中没有解决的问题：

  def index
    @posts = Post.paginate(:page => params[:page], :per_page => 2 )

    respond_to do |format|
    format.html # index.html.erb
    format.xml  { render :xml => @posts }
  end
end

Gemfile：gem "will_paginate-rails3", '~> 3.0.pre'

posts / index.html.erb：<%= will_paginate @posts %>

NoMethodError: NoMethodError (undefined method `paginate' for #<Class:0x12c3438>):
  app/controllers/posts_controller.rb:5:in `index'

Answer 1

尝试使用

def index
    @posts = Post.all.paginate(:page => params[:page], :per_page => 2 )

    respond_to do |format|
    format.html # index.html.erb
    format.xml  { render :xml => @posts }
  end
end

Answer 2

我只使用

gem 'will_paginate'

在我的Gemfile中它可以正常工作

Answer 3

尝试将其放入Gemfile中：

gem "will_paginate", "~> 3.0.pre2"

Answer 4

尝试删除“全部”。我有同样的问题，因为我删除了“全部”，它现在有效。我的代码看起来像这样： .all.paginate：per_page =＆gt; events_per_page，：page =＆gt; PARAMS [：页面] 删除分页前的“all”。希望对你有效。：）
