Question

我遵循http://filterrific.clearcove.ca中的指南。我尝试添加到我的应用filterrifc gem进行排序，但是它不起作用。我不明白为什么。我将不胜感激。我的模特：

  filterrific(
     default_filter_params: { sorted_by: 'created_at_desc' },
     available_filters: [
        :sorted_by,
        :with_title,
        :with_spec,
        :with_created_at_gte
    ]
    )

belongs_to :user

scope :sorted_by, lambda { |sort_option|
    direction = (sort_option =~ /desc$/) ? 'desc' : 'asc'
    case sort_option.to_s
    when /^created_at_/
        order("post.created_at #{ direction }")
    when /^title_/
        order("LOWER(post.title) #{ direction }")
    when /^spec/
        order("LOWER(post.spec) #{ direction }")
    else
        raise(ArgumentError, "Invalid sort option: #{ sort_option.inspect }")
    end
}

    scope :with_title, lambda { |titles|
        where(:title => [*titles])
    }   
    scope :with_spec, lambda { |specs|
        where(:spec => [*specs])
    }
    scope :with_created_at, lambda { |ref_date|
        where('post.created_at => ?', Data.strptime(ref_date, "%m/%d/%Y"))
    }

    def self.options_for_sorted_by
        [
            ['title (a-z)', 'title_asc'],
            ['title (z-a)', 'title_desc'],
            ['Created date (newest first)', 'created_at_desc'],
            ['Created date (oldest first)', 'created_at_asc'],
            ['spec (0-9)', 'spec_asc'],
            ['spec (9-0)', 'spec_desc'],
        ]

我的控制器 def秀 @user = User.find（params [：id]）

    @filterrific = initialize_filterrific(
        @user.posts,
        params[:filterrific],
        select_options: {
            sorted_by: @user.posts.options_for_sorted_by },
            persistence_id: 'shared_key',
            default_filter_params: {},
            available_filters: [:sorted_by, :with_title, :with_spec, :with_created_at],
            sanitize_params: false
            ) or return
    @posts = @filterrific.find.page(params[:page])
# Respond to html for initial page load and to js for AJAX filter updates.
respond_to do |format|
    format.html
    format.js
end

rescue ActiveRecord::RecordNotFound => e
    puts "Had to reset filterrific params: #{ e.message }"
    redirect_to(reset_filterrific_url(format: :html)) and return
end

And my view table:

<div id="filterrific_results">
<table class="table table-striped table-bordered table-list">
 <thead>
  <tr>
   <th><%= filterrific_sorting_link(@filterrific, :title) %></th>
   <th><%= filterrific_sorting_link(@filterrific, :spec) %></th>
   <th>Tags</th>
   <th><%= filterrific_sorting_link(@filterrific, :created_at) %></th>
  </tr>
 </thead>

 <tbody id="myTable">
  <% @user.posts.each do |post| %>
   <tr>
    <td><%= post.title %></td>
    <td><%= post.spec %></td>
    <td><% post.tag_list.each do |tag| %>
     <a class="badge badge-info"><%= tag %></a>
    <% end %>
    </td>
     ...
   </tbody>
</table>
</div>

在终端上一切正常，没有任何错误或异常
