小编fri*_*shi的帖子

我有以下型号:

Post.rb

  class Post < ActiveRecord::Base

  belongs_to :category
  has_many :attachments, :dependent => :destroy
  has_many :citations, :dependent => :destroy

  validates :title, :category_id, :content, :presence =>true

  acts_as_taggable_on :keywords
  accepts_nested_attributes_for :attachments, :allow_destroy => true, 
         :reject_if => proc { |attributes| attributes['photo'].blank?}
  accepts_nested_attributes_for :citations, :allow_destroy=>true

end

Attachment.rb

  class Attachment < ActiveRecord::Base

  belongs_to :post

  has_attached_file :photo, :styles => { :medium => "637x471>", 
                :thumb => Proc.new { |instance| instance.resize },
                :carousel => Proc.new { |instance| instance.decide_style }
                },
                :url => "/pictures/:style/:basename.:extension",
                :path =>":rails_root/public/pictures/:style/:basename.:extension"


  validates_attachment_content_type :photo, :content_type => …

我面临一个奇怪的问题.

我有 Post has_many attachments. as: :imageable

和 Attachment belongs_to imageable, polymorphic: true

我正在尝试使用dropzone.js上传附加到单个帖子的多个图像

但是,每当我以dropzone驱动的形式上传多个文件时,每个图像都会作为自己的帖子上传.我上传了4张图片,每张附图都有4张帖子.如何才能将我附加到帖子的所有图片仅与该帖子相关联？

这是posts.js看起来像:

 $(document).ready(function(){
  // disable auto discover
  Dropzone.autoDiscover = false;

 // grap our upload form by its id
 $("#new_post").dropzone({

 // restrict image size to a maximum 1MB
 maxFilesize: 1,

 // changed the passed param to one accepted by
 // our rails app

 paramName: "post[attachments_attributes][][picture]",
 // show remove links on each image upload
 addRemoveLinks: true
  });
});

从中创建动作 PostsController

def create
@post = Post.create(post_params)


if …

我对我实现的旋转木马采取了不同的方向,选择了bxSlider而不是jCarousel.这是我正在建立的图像库http://rjwcollective.com/equinox/rishi_gallery/eqgall.php

我遇到的问题是当我重置过滤器,或选择不同的过滤器时,滑块不会重置.这是初始负载的代码:

    //first load
$.ajax({
    type:"POST",
    url:"sortbystate.php",
    data:"city=&gender=&category=",
    success:function(data){
            //carousel

            $('#thumbs').html(data);


            //alert("whoa, careful there!");
                 $('#thumbs').bxSlider({auto: false, mode:'vertical',
                            autoControls: false,
                            autoHover: true,
                            pager: false,
                            displaySlideQty: 4,
                            speed:800,
                            infiniteLoop: true,      
                            moveSlideQty: 4,

                            controls: true});
    }

});//end ajax

这是处理过滤器更改的代码:

$(".statelist :input").click(function(){

    var carousel = $('#thumbs').data('jcarousel');  
    var state = $('.statelist input:checked').attr('value');
    var gender = $('.gender input:checked').attr('value');
    var category =$('.category input:checked').attr('value');
        $.ajax({
            type:"POST",
            url:"sortbystate.php",
            data:"city="+state+"&gender="+gender+"&category="+category,
            success:function(data){
                    //alert("whoa, careful there!");

                    $('#thumbs').html(data);
                         $('#thumbs').bxSlider({auto: false, mode:'vertical',
                                    autoControls: false,
                                    autoHover: true,
                                    pager: false,
                                    displaySlideQty: 4,
                                    speed:800,
                                    infiniteLoop: true, …
