我正在尝试创建一个id数组,以便我可以查询某个id是否与某个对象相关联。这是我的方法,但它不会在数组中添加id。
class Report
include Mongoid::Document
has_and_belongs_to_many :reportapprovals, class_name: "Reportapproval", inverse_of: :report
def bind_reportapproval
@reportapprovals = Reportapproval.where(tenant_id: self.tenant_id).all
if @reportapprovals.present? && @reportapprovals.any? { |ra| ra.tenant_approved == true }
@reportapprovals.each do |ra|
self.reportapproval_ids = ra.id
end
end
end
end
这是为了向report对象添加一个reportapproval_ids数组。

您将数组的值设置为等于一个ID。试试这个:
if true # use correct conditional statement
self.reportapproval_ids = @reportapprovals.pluck(:id)
end

Rails实际上有一个方法:
