針對子集條件的活動記錄查詢

Question

在我的應用程序中，員工用戶創建患者記錄。患者模型與保險模型具有HABTM關係，以記錄患者所覆蓋的保險。

員工用戶創建屬於患者的推薦請求。職員用戶也屬於大學，而大學又屬於市場。例如，職員用戶吉姆可能屬於哈佛大學，而哈佛大學又屬於波士頓市場。

臨牀醫生用戶直接屬於市場。

臨牀醫生用戶每個人都有一個臨牀醫師簡介，他們的檔案與保險模型有HABTM關係，以記錄保險/臨牀醫生接受的保險。 ClinicianProfile屬於用戶角色::臨牀醫師。

的角色與一個枚舉定義：

enum role: { staff: 0, clinician: 1, admin: 2 } 

甲人員用戶創建患者記錄，它直接流入創建推薦請求，它直接流入分派/新我打算顯示一個列表的所有臨牀醫生在其市場中接受至少一種病人所覆蓋的保險。這正在找出如何實際向這些臨牀醫生髮送轉診請求和相關患者詳細信息的途徑。我在下面評論了我正在嘗試對每一步做什麼，以及哪些行不通 - 對於如何做到這一點的任何建議將不勝感激。

急件控制器的新行動：

def new 
#This works 
@patient = @referral_request.patient 
#This works 
@user = current_user 

#This works - returns a list of clinician users who match the current user's university's market. 
@market_matched_clinicians = User.clinician.where(market: @user.university.market) 

#This doesn't work -My intention is for this to return a list of clinician profiles that share at least one insurance with the patient. 
@matched_clinician_profiles = ClinicianProfile.where(insurances: [@patient.insurances]) 

#Once I have all of the matched clinician profiles, how can I use that to return the corresponding clinician users? 
# @matched_clinicians = ??? 


@dispatch = @referral_request.dispatches.new 
end 

型號：

class User < ApplicationRecord 
    include Clearance::User 
    include StaffUser 
    include ClinicianUser 
    include AdminUser 

module ClinicianUser 
    extend ActiveSupport::Concern 

    included do 
    has_one :clinician_profile 
    has_many :lists 
    has_many :universities, through: :lists 
    has_many :dispatches 
    has_many :referral_requests, through: :dispatches 
    after_create :create_clinician_profile 
    belongs_to :market 
    validates :market_id, presence: true, if: :clinician? 
    end 

class ClinicianProfile < ApplicationRecord 
    belongs_to :user, -> { where role: :clinician } 
    has_and_belongs_to_many :languages 
    has_and_belongs_to_many :races 
    has_and_belongs_to_many :insurances 
    has_and_belongs_to_many :genders 
end 

class Patient < ApplicationRecord 
    belongs_to :author, -> { where role: :staff }, class_name: 'User', foreign_key: 'user_id' 
    has_and_belongs_to_many :genders 
    has_and_belongs_to_many :concerns 
    has_and_belongs_to_many :insurances 
    has_and_belongs_to_many :races 
    has_many :referral_requests 
    belongs_to :staff_doctor, class_name: 'User', foreign_key: 'staff_doctor_id' 

    validates :staff_doctor_id, presence: true 

class ReferralRequest < ApplicationRecord 
    belongs_to :user, -> { where role: :staff } 
    belongs_to :patient 
    has_many :dispatches 
    has_many :clinicians, through: :dispatches 
    has_and_belongs_to_many :languages 
    has_and_belongs_to_many :races 
    has_and_belongs_to_many :genders 
    validates :user_id, presence: true 

    enum status: { created: 0, sent: 1, shared: 2, closed_under_care: 3, closed_not_seeking_care: 4, closed_unresponsive: 5 } 
end 

這裏就是我試圖使這些結果的看法：

<% provide(:title, "New Dispatch") %> 

<h2> These clinicians match your market and your patient's insurance </h2> 

    <table class="table table-striped"> 
     <thead> 
     <tr> 
      <th>Provider ID</th> 
      <th>Name</th> 
      <th>Provider Market</th> 
      <th>Insurances Accepted</th> 
      <th>Gender/s</th> 
      <th>Race/Ethnicity</th> 
      <th>Languages</th> 

     </tr> 
    </thead> 
    <tbody> 

    <% @users.each do |user| %> 
     <tr> 
     <td><%= user.id %></td> 
     <td><%= user.name %></td> 
     <td><%= user.market.name %></td> 
     <td><%= user.clinician_profile.insurances.map(&:name).to_sentence %></td> 
     <td><%= user.clinician_profile.genders.map(&:name).to_sentence %></td> 
     <td><%= user.clinician_profile.races.map(&:name).to_sentence %></td> 
     <td><%= user.clinician_profile.languages.map(&:name).to_sentence %></td> 
     </tr> 
    <% end %> 
    </tbody> 
    </table> 

Answer 1

拿到賽至少一個保險是ClinicianProfiles：

@profiles = ClinicianProfile.joins(:insurances) 
          .where(insurances: { id: @patient.insurances }) 
          .group('clinician_profiles.id') 
          .having("count(*) = 1") 

然後，您可以通過加入clinician_profiles獲取用戶：

@users = User.joins(:clinician_profile) 
      .where(
       market: @user.university.market, 
       clinician_profile: { id: @profiles } 
      ) 

Answer 2

以Rails的方式做到這一點。 我假設您定義了與保險模型中的臨牀醫師資料相關聯。將has_many :clinician_profiles, through: insurances添加到患者並呼叫@ patient.clinician_profiles。

class Patient < ApplicationRecord 
    belongs_to :author, -> { where role: :staff }, class_name: 'User', foreign_key: 'user_id' 
    has_and_belongs_to_many :genders 
    has_and_belongs_to_many :concerns 
    has_and_belongs_to_many :insurances 
    has_and_belongs_to_many :races 
    has_many :clinician_profiles, through: insurances 
    has_many :referral_requests 
    belongs_to :staff_doctor, class_name: 'User', foreign_key: 'staff_doctor_id' 

    validates :staff_doctor_id, presence: true
