Ruby on rails Rails-从has_many:through模型中选择额外字段

我有以下结构

class Project
  has_many :teammates
  has_many :users, :through => :teammates
end

class Teammate
  belongs_to :user
  belongs_to :project
end

class User
  has_many :teammates
  has_many :users, :through => :teammates
end

我在加入模型中添加了一个额外的字段：队友->待定：布尔值

我想做的是显示一个项目，其中包括使用布尔值的用户，以了解每个用户是否仍处于挂起状态

编辑：查询如下所示：

Project.includes(:users).find(params[:id])

@project = Project.find(params[:id])
@project.teammates.each do |teammate|
  # an example provided to show that you have access to `pending` field as well as all users fields:
  teammate.pending # pending field
  teammate.user # all user fields
end

我希望能够做到以下几点：

class Project
  has_many :teammates

  # I tried this
  has_many :users, :through => :teammates, :select => 'users.*, teammates.*'
  # ERROR: Unknown key: :select

  # And this
  has_many :users, -> { select("users.*, teammates.pending") }, through: :teammates
  # ERROR: missing FROM-clause entry for table "teammates"
end

---

我会这样做：

Project.includes(:users).find(params[:id])

@project = Project.find(params[:id])
@project.teammates.each do |teammate|
  # an example provided to show that you have access to `pending` field as well as all users fields:
  teammate.pending # pending field
  teammate.user # all user fields
end

你的问题是什么？问题是当我进行查询时，只有用户被抓取。布尔值不是结果的一部分。您的查询是什么样子的？我编辑了问题它不会解决您的问题，但有很多问题：班上缺少队友用户。
