Ruby on rails 我正在尝试用参数加入ruby。我犯了一个错误

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

class Bvadmin:：employeeapplicator范围：全职员工新员工，->（开始日期，结束日期）{employeeapplicator.joins（：employeeapplications）。其中(“confirfied_eod>=？and confirfied_eod您的类名是'Bvadmin:：employeeappender'，但您在范围中使用了'employeeappender'，因此它试图在此类'Bvadmin:：employeeappender'中查找常量'employeeappender'，这就是为什么出现'uninitialized constant Bvadmin:：employeeappender:：employeeappender'错误的原因

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

这个类中的self是Bvadmin:：employeeapplicator，所以你可以像下面这样做

已更新

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

我替换了这一行，但当我尝试这样做时：所以我的另一个模型是：class Bvadmin:：EmployeeApplication（startdate，enddate）{加入（：bvadmin:：EmployeeApplications）。其中（“已确认的eod>=”和已确认的eod错误是什么？：bvadmin:：EmployeeApplications不是关联，它应该是joins（：employee_applications）。我在代码中也更新了关联，可能这就是您现在遇到的问题。
 has_many :employee_applications, class: "Bvadmin::EmployeeApplicantion"
