卡米纳里铁路的原始儿童模式3.1
原标题:Paginate child models Kaminari on rails 3.1

页: 1

关系是:

-图像属于一类。

<>strong>-类别有许多图像。

关于<代码>index.html.erb 参考文献目录 物体,我想为所有类别的每页 2020个图像。

我指的是,我想从所有类别的图像中抹去,每页有20个图像。

http://www.un.org/Depts/DGACM/index_french.htm 方法一:

def index
    @categories = Category.all
    @categories.each do |category| 
     @images = Kaminari.paginate_array(category.images).page(1).per(1)
    end
    respond_to do |format|
      format.html # index.html.erb
      format.json { render json: @categories }
    end
   end

页: 1 我有:

<% @images.each do |image|%>

code for each image here

<% end %>  
<% paginate @images %>

但对于我来说,这并不奏效。 我看不到任何形象。

<>光> 我可以执行这一功能? 并解决这一问题? 谢谢。

最佳回答
@categories.each do |category| 
  @images = Kaminari.paginate_array(category.images).page(1).per(1)
end

在座右翼中,你每次都重压@images,很显然,你赢得了你们的期望。

我认为,你做的是:

@images = Image.where("category_id IS NOT NULL").page(params[:page]).per(20)

如果图像必须属于某一类别,则无需<代码>。
