Question

我有一个自定义列表，我从“后台”创建，我在其中添加要从数据库表中检索的列。这成了一个数组。好吧，我想从与Id匹配的行中只检索那些列。

这是我的代码：

def load_import_contacts
    @import_contacts_column_filter = current_user.current_organization.import_columns.split(/,/) # the "custom filter" that retrieve columns
    @import_contacts = UserImport.select(@import_contacts_column_filter).where(organization_id: current_user.current_organization.id) # the query
    # here all ok, objects filtered how i want.
    @import_contacts_listing = smart_listing_create(
      # here comes the error message
      :import_contacts,
      @import_contacts,
      partial: 'contacts/listing_import',
      default_sort: {created_at: "desc"}
    )
  end

错误消息：

标题

ActiveRecord::StatementInvalid in ImportsController#index

正文消息

Mysql2::Error: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ' name, surname1, surname2, phone, adress, city, zipcode, zone, birthdate, firstv' at line 1: SELECT COUNT(reference_number, name, surname1, surname2, phone, adress, city, zipcode, zone, birthdate, firstvisit, mutua, organization_id) FROM `user_imports` WHERE `user_imports`.`organization_id` = 279

第15行：

@import_contacts_listing = smart_listing_create(

奇怪的解决方案：

当我在智能列表之前添加此行

**@import_contacts.each do |before|
end**

一切运行正常，很奇怪，我不知道为什么会这样。

ActiveRecord，对Array的select查询返回ImportsController #index中的ActiveRecord :: StatementInvalid
