在rails中嵌套搜索

Question

我有一个current_user是一个顾问，有很多项目

 has_many :advisorizations, :dependent => :destroy
 has_many :projects, :through => :advisorizations

每个项目都有很多用户;

 has_many :projectizations, :dependent => :destroy
 has_many :users, :through => :projectizations

现在我想在curren_users用户中搜索，即。作为current_user是顾问的项目的用户的用户。

current_user.projects.users

给出了一个错误，比如“未定义的方法`用户'＃

Answer 1

您应该能够通过添加到您的顾问类来实现这一目标：

has_many :advisorizations, :dependent => :destroy
has_many :projects, :through => :advisorizations
has_many :projectizations, :through => :projects
has_many :users, :through => :projectizations

然后你应该可以做current_user.users虽然这可能会令人困惑

Answer 2

 @users = []   
 current_user.projects.each{|project| @users << project.users }
