使用Filterrific的Rails不起作用

标签: ruby-on-rails ajax sorting filterrific

虽然我觉得我非常接近解决方案,但我并没有过滤掉工作。在我的应用程序中,您可以为其他人可以回答的产品创建搜索请求。现在我想实现filterrific来排序(以后也过滤)这些搜索请求。我按照http://filterrific.clearcove.ca/上的精彩文档进行了操作,但我找不到它在我的应用程序中无效的原因。我没有得到任何错误,但无论我做什么都没有排序。

这是我的搜索模型:

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

scope :sorted_by, lambda { |sort_option|
  # extract the sort direction from the param value.
  direction = (sort_option =~ /desc$/) ? 'desc' : 'asc'
  case sort_option.to_s
  when /^created_at_/
    # Simple sort on the created_at column.
    # Make sure to include the table name to avoid ambiguous column names.
    # Joining on other tables is quite common in Filterrific, and almost
    # every ActiveRecord table has a 'created_at' column.
    order("searches.created_at #{ direction }")
  else
    raise(ArgumentError, "Invalid sort option: #{ sort_option.inspect }")
  end
}


def self.options_for_sorted_by
    [
      ['Created at (Newest first)', 'created_at_desc'],
      ['Created at (Oldest first)', 'created_at_asc']
    ]
end  

这是我的搜索控制器:

def index

 @filterrific = initialize_filterrific(
      Search,
      params[:filterrific],
      select_options: {
        sorted_by: Search.options_for_sorted_by
      },
      persistence_id: 'shared_key',
      default_filter_params: {},
      available_filters: [],
  ) or return
  @searches = @filterrific.find.paginate(page: params[:page], per_page: 5)

  respond_to do |format|
    format.html
    format.js
end

end

这是我的index.html.erb:

<%= form_for_filterrific @filterrific do |f| %>

<div>
    Sorted by
    <%= f.select(:sorted_by, @filterrific.select_options[:sorted_by]) %>
</div>
<div>
    <%= link_to(
      'Reset filters',
      reset_filterrific_url,
    ) %>
  </div>
  <%= render_filterrific_spinner %>
  <% end %>

  <%= render 'searches/search', locals: { searches: @searches } %>

这是我的部分_search.html.erb:

<div id="filterrific_results">
<% @searches.each do |search| %>
<%= time_ago_in_words(search.created_at) %>
...
<% end %>
</div>  
<%= will_paginate @searches %>

最后,我的index.js.erb:

<% js = escape_javascript(
  render(partial: 'searches/search', locals: { searches: @searches })
) %>
$("#filterrific_results").html("<%= js %>");

为什么我觉得接近解决方案? 从&#39; created_at_desc&#39;更改default_filter_params到&#39; created_at_asc&#39;工作中。此外,选项选择列表也会自动更改为在(最早的第一个)创建的&#39;。但是当我更改选项时,选择什么都不会发生,除了微调器显示一秒钟。

感谢您的帮助!

我自己就找到了解决方案。我将:sorted_by添加到搜索控制器。
