创建on Rails的筛选查询等方法，smart_listing宝石

Question

我想一个表的谁我smart_listing宝石

未知创建的内容过滤，SmartListing也被称为smart_listing是一个Ruby宝石它提供一个工具，在您的Rails应用程序创建列表

我能使用分页，但过滤器仍然没有工作

Link to smart_listing documentation for Controls (filtering) documentation section

在文档说：

# Apply the search control filter. 
    # Note: `like` method here is not built-in Rails scope. You need to define it by yourself. 
    users_scope = users_scope.like(params[:filter]) if params[:filter] 

这是我的代码，我怎么可以让运行过滤器？我有这样的控制器上

if !current_user.current_organization.import_columns.nil? 
     @import_contacts = UserImport.where(organization_id: current_user.current_organization.id) 

     @import_contacts_column_filter = current_user.current_organization.import_columns.split(/,/) 
     contacts_import_scope = @import_contacts 
     contacts_import_scope = contacts_import_scope.like(params[:filter]) if params[:filter] 
     #contacts_import_scope = begin_of_association_chain.order('active DESC') 
     #contacts_import_scope = contacts_import_scope.imported_users_filter(params[:filter].strip) if params[:filter] 
     @import_contacts_listing = smart_listing_create(
     :import_contacts, 
     contacts_import_scope, 
     partial: 'contacts/listing_import', 
     default_sort: {created_at: "desc"} 
    ) 
    end 

这对意见

index.html.slim

.tab-content 
     - if @import_contacts.any? 
     .search-wrapper.pull-right 
      = smart_listing_controls_for(:import_contacts) do 
      span.btn.pull-right 
       i.fa.fa-search 
      .filter.input-append.pull-right 
       = text_field_tag :filter, '', class: 'search', placeholder: "#{t('commons.filters.search_pending_petition_contacts')}", autocomplete: 'off' 

_listing_import.slim

- unless smart_listing.empty? 
    .pending_contacts_table.table-responsive 
    table class="table-striped table-list" style="width: 100%; background-color: #FAFBFD;" 
     thead 
     tr 
      - @import_contacts_column_filter.each do |column| 
      th.name.col-sm-2 = smart_listing.sortable "#{column}", "#{column}" 
      th.name.col-sm-2 Añadir 
     tbody 
     - smart_listing.collection.each do |user_imported| 
      tr 
       - @import_contacts_column_filter.each do |field| 
       td = "#{user_imported.send(field)}" 
       td 
       - if User.exists?(email: user_imported.email) 
        p Ya añadido 
       - else 
        - last_name = "#{user_imported.surname1}"+"#{user_imported.surname2}" 
        = link_to new_organization_customer_path(name: user_imported.name, last_name: last_name, email: user_imported.email, tmp_pass: user_imported.tmp_pass), class: 'btn btn-success' do 
        i class='fa fa-plus-square' 
    = page_entries_info smart_listing.collection 
    = smart_listing.paginate 
- else

我们如何定义文档的.like方法？

正如我写的代码，并留下评论，在我试图用这种方式写也没有结果。

#contacts_import_scope = contacts_import_scope.imported_users_filter(params[:filter].strip) if params[:filter]

解决！

问题是与ImportsController，必须在其上，而不是在ContactsController定义。

也终于控制器看起来这

def load_import_contacts 
    @import_contacts_column_filter = current_user.current_organization.import_columns.split(/,/) 
    @import_contacts = UserImport.where(organization_id: current_user.current_organization.id) 
    @import_contacts = @import_contacts.where("name Like ? OR surname1 LIKE ? OR surname2 LIKE ? OR reference_number LIKE ? OR email LIKE ? OR mutua LIKE ?", "%#{params[:filter]}%","%#{params[:filter]}%", "%#{params[:filter]}%", "%#{params[:filter]}%","%#{params[:filter]}%", "%#{params[:filter]}%") if params[:filter] 
    @import_contacts_listing = smart_listing_create( 
     :import_contacts, 
     @import_contacts, 

而且_listing_import.slim ...

@import_contacts = @import_contacts.where("name Like ? OR surname1 LIKE ? OR surname2 LIKE ? OR reference_number LIKE ? OR email LIKE ? OR mutua LIKE ?", "%#{params[:filter]}%","%#{params[:filter]}%", "%#{params[:filter]}%", "%#{params[:filter]}%","%#{params[:filter]}%", "%#{params[:filter]}%") if params[:filter] 

最后，过滤器和分页的作品！
