Question

我正在构建房东mgt应用程序。但是我遇到了一个问题-我只想索引house.id（关联值）与当前用户匹配的请求。

当前，我已经根据用户是否创建了它来工作了。但我希望房东能看到与其财产有关的所有要求。

requests_controller.rb：

def index
  unless current_user.estate_agent?
    @requests = Request.where(user_id: current_user).search(params[:search])
  else
    @requests = Request.search(params[:search])
  end
end

request.rb

class Request < ActiveRecord::Base
  belongs_to :user
  belongs_to :house

  def self.search(search)
    key = "%#{search}%"
    if search
      where('description LIKE ? OR title LIKE ?', key, key)
    else
      all
    end
  end
end

house.rb

class House < ActiveRecord::Base
  belongs_to :user
  belongs_to :tenant
  has_many :requests
  belongs_to :contract

  mount_uploader :energy, EnergyUploader

  validates_presence_of :house_title, :description, :doorno, :postcode, :price, :bedroom, :house_type

  def full_house_name
   "#{doorno} #{house_title}"
  end

  def self.search(search)
    key = "%#{search}%"
    if search
      where('doorno LIKE ? OR house_title LIKE ? OR price LIKE ? OR postcode LIKE ? OR house_type LIKE ? OR bedroom LIKE ?', key, key, key, key, key, key)
    else
      all
    end
  end
end

Answer 1

如果我对您的理解正确，则希望显示用户提出的或针对其真实情况提出的所有请求。

下面的代码将创建您的初始过滤器，然后您可以在其上调用search方法。

Request.where(user_id: current_user.id).or(Request.where(house: { user_id: current_user.id}))

显示结果取决于关联
