分頁與軌道阿賈克斯2.3.8

Question

任何人都可以建議我怎麼在軌使用will_paginate與阿賈克斯2.3.8 我應該怎麼做在下面的代碼行變化ClientController

def index 

    @clients = Client.paginate(:per_page => 5, :page => params[:page]) 
    respond_to do |format| 
     format.html # index.html.erb 
     format.xml { render :xml => @clients } 
    end 

end 

，並在索引視圖文件

<%= will_paginate @clients %> 

Answer 1

will_paginate沒有本機AJAX支持，但確實提供切換鏈接呈現。添加以下類RAILS_ROOT/lib添加到remote_link_renderer.rb，使鏈路的AJAX回調渲染視圖適合：

class RemoteLinkRenderer < WillPaginate::LinkRenderer 
def prepare(collection, options, template)  
    @remote = options.delete(:remote) || {} 
    super 
end 
protected 
def page_link(page, text, attributes = {}) 
    @template.link_to_remote(text, {:url => url_for(page), :method => :get}.merge(@remote)) 
    #replace :method => :post if you need POST action 
end 
end 

使用此在您的觀點呈現分頁鏈接（需要定製）：

<%= will_paginate(@results, :params => {:controller => :mycontroller, :action => :search, :query => h(@query)}, :renderer => RemoteLinkRenderer, :page_links => false) %> 

由於您需要替換呈現這些分頁鏈接和結果的視圖，控制器會變得更棘手。我使用的是這樣的：

if request.xhr? or request.post? 
    if params[:page] 
     render :update do |page| 
     page.replace_html :search_results, :partial => 'mycontroller/search_results', :layout => false 
     end 
    else 
     render :partial => 'mycontroller/search_results' 
    end 
    else 
    # Render some normal content here 
    end
