Question

我有一个销售代表的应用程序。我试图根据2件事情提取不同的机构信息

如果他们是客户
如果他们处于用户（销售代表）结束的状态。

所以我想在current_user（销售代表）区域显示所有客户机构。我怎样才能做到这一点？

由于我之前没有这样做过，而且我对rails更新，我不知道该怎么做。

以下是我的模型（我缩短了代码）：

用户（销售代表）

class User < ActiveRecord::Base
  has_many :states, :through => :rep_areas
  has_many :institutions, :through => :company_reps
  has_many :rep_areas
  has_many :company_reps
end

国

class State < ActiveRecord::Base
  has_many :users, :through => :rep_areas
  has_many :rep_areas
  has_many :institutions

  attr_accessible :code, :name
end

机构

class Institution < ActiveRecord::Base
  attr_accessible :company, :phone, :clientdate, :street, :city, :state_id, :zip, :source, :source2, :demodate1, :demodate2, :demodate3, :client, :prospect, :notcontacted
  belongs_to :state
  has_many :users, :through => :company_reps
  has_many :company_reps
end

Answer 1

我建议以这种方式继续：

states = current_user.states.to_a

# the following are all the Institution record in all the user's areas
inst_in_states = Institution.where(state_id: states)
# it will take an array and make an "IN" query

# the following are all the user's own clients, additionally on the states
# the user is in.
clients_in_states = current_user.institutions.where(state_id: states)
# as above, but additionally use the :company_reps join

选择销售代表区域
