Question

我在搜索关系字段时遇到了搜索问题。我的模型如下：

ListView<String>

在控制器中，索引操作负责搜索：

# Model to search in
class Pass < ActiveRecord::Base
    belongs_to :user, polymorphic: true
    belongs_to :admin
    belongs_to :last_owner, polymorphic: true
end

# User class having phone
class User < ActiveRecord::Base
    has_many :passes
    has_many :owned_passes, class_name: 'Pass', foreign_key: 'owner_id'
    has_many :last_owned_passes, class_name: 'Pass', foreign_key: 'last_owner_id'
end

# Doesn't have phone column
class Admin < ActiveRecord::Base
    has_many :passes
    has_many :owned_passes, as: :owner, class_name: 'Pass', foreign_key: :owner_id
    has_many :last_owned_passes, as: :last_owner, class_name: 'Pass', foreign_key: :last_owner_id
end

#Doesn't have phone column
class Moderator < Admin
end

根据有关搜查的文件：cellFactory search_form_for如下：

class Dashboard::PassesController < Dashboard::BaseController
    def index
        @query  = scope.search(params[:q])
        @passes = @query.result(distinct: true).page(page)
    end
private
    def scope
        scope = current_dashboard_admin.passes
        scope = scope.where(parent_id: params[:parent_id]) if params.key? :parent_id
        scope = scope.order(created_at: :desc)
        scope = scope.where(type: 'Pass')
        scope
    end
end

运行此代码会导致错误：Ransack :: Search＆gt;的未定义方法`user_phone_cont'：Ransack :: Search

我尝试将索引操作更改为如下：= search_form_for [:dashboard, @query] do |f| .form-body .form-group = f.label :user_phone_cont = f.text_field :user_phone_cont, class: 'form-control'但是这不起作用并导致相同的错误。我试图将text_field更改为search_field，结果相同。我还尝试在2行上建立用户关系，通过在Pass模型中添加以下行来修改Pass模型中的关系来区分用户是User和其他任何人：@passes = @query.result.includes(:user).page(page)然后修改表单是normal_user_phone_cont，并且导致与未定义的属性/方法的命名更改相同的错误。

任何帮助将不胜感激，并提前感谢您阅读该问题。

我认为使用Ransack搜索多态关系有一些约定，如以下链接所述： https://github.com/activerecord-hackery/ransack/wiki/Polymorphic-searches

根据您的情况，您应该使用以下约定：user_of_user_type_phone，以便仅搜索用户。

使用ransack gem搜索多态关系
