Question

控制器代码：

@fte_new_hires = Bvadmin::EmployeeApplicant.fte_new_hires(next_startdate, next_enddate)

型号代码：

class Bvadmin::EmployeeApplicant < Bvadmin::Record
  self.table_name = "BVADMIN.EMPLOYEE_APPLICANTS"
  self.primary_key = :applicant_id
  has_many :employeeapplications

  scope :fte_new_hires, -> (startdate,enddate) {EmployeeApplicant.joins   (:employeeapplications).where("confirmed_eod >= ? and confirmed_eod <= ?", startdate, enddate).order('name ASC') }
end

获取以下错误：

未初始化的常量Bvadmin :: EmployeeApplicant :: EmployeeApplicant

Answer 1

您的班级名称是＆＃39; Bvadmin :: EmployeeApplicant＆＃39;，但您使用了＆＃39; EmployeeApplicant＆＃39;在范围内，所以它试图找到不变的EmployeeApplicant＆＃39;在这个班级＆＃39; Bvadmin :: EmployeeApplicant＆＃39;，这就是为什么你得到了未初始化的常量Bvadmin :: EmployeeApplicant :: EmployeeApplicant＆＃39;错误

 joins is equivalent to self.joins which is equivalent to Bvadmin::EmployeeApplicant.joins

本课程中的自我是Bvadmin :: EmployeeApplicant，所以你可以这样做，

已更新

 scope :fte_new_hires, -> (startdate,enddate) {joins(:employee_applications).where("confirmed_eod >= ? and confirmed_eod <= ?", startdate, enddate).order('name ASC') }

如下所示更改您的协会：

 has_many :employee_applications, class: "Bvadmin::EmployeeApplicantion"

我正在尝试使用参数进行ruby连接。我收到了一个错误
