我PARAMS哈希看起來是這樣的：Parameters: {"id"=>"6", "bonus_id"=>"2", "bonus_title"=>"deposit-match-row"}，這是我的控制器：無法找到與「ID」獎金=，而在軌道安慰一切正常
def load_more_bonuses
@more_casinos = []
@bonus_title = params[:bonus_title]
bonus = Bonus.find(params[:bonus_id])
@more_casinos << bonus.casinos.where('casinos.id >?', params[:id]).order(id: :asc).limit(6).uniq
respond_to do |format|
format.js
end
end
我得到以下錯誤：ActiveRecord::RecordNotFound (Couldn't find Bonus with 'id'=)在軌道控制檯中一切正常，做：bonus = Bonus.find(2)給我我的獎金記錄。上面的代碼有什麼問題，可以做些什麼來擺脫錯誤？謝謝。

Ajax調用在application.js
$('.bonus-casinos-load-more').click(function() {
var lastId = $(this).parent().parent().parent().children('.first-row').children().last().children().attr('data-id');
var bonusId = $(this).attr('data-id');

$.ajax({

data: {
id: lastId,
bonus_id: bonusId,
bonus_title: bonusTitle
},
dataType: 'script'
});

你有一些'before_action'或'after_action'或什麼在你的控制器？ – Iceman
不，沒有'before_action'或'after_action' –
'friendly_id'或這樣的寶石？ – Iceman
