Ruby on rails 与卡米纳里宝石有麻烦

我正在尝试使用Kaminari Gem对多个表进行分页。我试图通过在我的应用程序控制器中生成一个数组来实现这一点，如下所示：

@paginate = %w(errors messages subscribers).page(params[:page]).per(15)

<%= paginate @paginate %>

然后，我使用了

@paginate

并将其用于我的一个部分，然后呈现表格，如下所示：

@paginate = %w(errors messages subscribers).page(params[:page]).per(15)

<%= paginate @paginate %>

以下是我得到的代码：

应用程序\u控制器.rb

layout "admin"

#Setup

#Index

def index
    @users = User.all
    @attributes = %w(messages subscribers)
    @paginate = %w(errors messages subscribers).page(params[:page]).per(15)
end

#Create

    create! { collection_path }

end

    attributes = attributes(@resource) + %w(user_id admin_id) + [image_pages_attributes: [:caption, image_attributes: [:image]]]
    params.permit(@model => attributes)
end

如果你还需要什么，请告诉我，我会把它挂起来的

谢谢

您没有正确设置“页面”。应该是这样的：

paginate(:page => params[:page], :per_page => 15)

在你的例子中

@paginate = %w(errors messages subscribers).page(params[:page]).per(15)

你真正想要的是：

@paginate = %w(errors messages subscribers).paginate(:page => params[:page], :per_page => 15)

非常感谢，我会试试看：-）让我知道进展如何。。。如果答案有帮助，不要忘记接受它。：）恐怕还是不行。我有同样的错误接受这次它不是“未定义的方法页面”现在是“未定义的方法页面”嗯。。。你在运行什么版本的gem？什么版本的rails？当您进行

捆绑显示时，它会说什么？“kaminari”、“~>0.15.0”
