Ruby on rails - Kaminari - 分頁搜索結果

Question

我有一個分頁搜索表單。兩種方式都可以單獨運行，但如果我搜索並加載下一頁，搜索參數將被遺忘，並且kaminari將顯示結果，而不管我選擇了哪些搜索選項。

我已閱讀文檔和其他stackoverflow帖子，但我沒有任何運氣。

我的索引頁有

<%= search_form_for @q, html: { id: "gig_search_form" }, remote: true do |f| %> 
bla bla bla... 
<% end %> 
<%= link_to_next_page @gigs, 'Next Page', :remote => true %> 

index.js.erb的

<% if params[:page] %> 
$('.gig-search-list').append("<%= j render(partial: 'gigs') %>"); 
<% else %> 
$('.gig-search-list').html("<%= j render(partial: 'gigs') %>"); 
<% end %> 

演出部分：

<% @gigs.each do |gig| %> 
     bla bla bla... 
    <% end %>

現在，我已經嘗試了一些我的吊環控制器，但我總是得到相同的結果。原本我有;

def index 
     if params[:search].present? 
     @q = Gig.notexpired.where(:filled => false).near(params[:search], 500, :order => 'distance').ransack(params[:q]) 
     else 
     @q = Gig.notexpired.where(:filled => false).ransack(params[:q]) 
     end 
     @allgigs = @q.result(distinct: true) 
     @gigs = @q.result(distinct: true).page(params[:page]).per(5) 
     respond_to do |format| 
     format.js 
     format.html 
    end 
    end 

然後;

def index 
     if params[:search].present? 
     @q = Gig.notexpired.where(:filled => false).near(params[:search], 500, :order => 'distance').ransack(params[:q]) 
     else 
     @q = Gig.notexpired.where(:filled => false).ransack(params[:q]) 
     end 
     @allgigs = @q.result(distinct: true) 
     @gigs = Kaminari.paginate_array(@allgigs).page(params[:page]).per(5) 
     respond_to do |format| 
     format.js 
     format.html 
    end 
    end 

然後我試着將它們分開;

def index 
     if params[:search].present? 
     @q = Gig.notexpired.where(:filled => false).near(params[:search], 500, :order => 'distance').ransack(params[:q]) 
     else 
     @q = Gig.notexpired.where(:filled => false).ransack(params[:q]) 
     end 
     @allgigs = @q.result(distinct: true) 
     if @allgigs.present? 
     unless @allgigs.kind_of?(Array) 
      @gigs = @allgigs.page(params[:page]).per(5) 
     else 
      @gigs = Kaminari.paginate_array(@allgigs).page(params[:page]).per(5) 
     end 
     end 
     respond_to do |format| 
     format.js 
     format.html 
    end 
    end 

但我每次都得到相同的結果。我可以在控制檯上看到，當我加載更多頁面時，搜索參數不包括在內。

我該如何將這兩件事鏈接在一起並正確分頁搜索結果？

服務器日誌。我以前添加了搜索參數。與搜索表單過濾

Answer 1

試試下面的代碼攜帶您的PARAMS下一頁

= link_to_next_page @gigs, "Next Page", :remote => true, :params => params 

Answer 2

您應該#page和#per方法添加到查詢本身。 Kaminari.paginate_array實際上是從整個陣列中分割出來的，效率不高。

這裏有一個片斷

def index 
    if params[:search].present? 
    @q = Gig.notexpired.where(:filled => false).page(params[:page]).per(5).near(params[:search], 500, :order => 'distance').ransack(params[:q]).results 
    else 
    @q = Gig.notexpired.where(:filled => false).page(params[:page]).per(5).ransack(params[:q]).results 
    end 

#... 

然後使用Kaminari PAGINATE助手在你看來

<%= paginate @q %>
