Question

我已经创建了一个属性，该属性应该使用子模型属性的值更新日期时间字段（如果它更新（或更旧基于哪个字段）

def update_project_record
    client = Client.find(project.client_id)
    puts client
    project.start_date = self.task_start_date if self.task_start_date < project.start_date 
    project.end_date = self.task_end_date if self.task_end_date > project.end_date
    if client.nearest_project_start.present?
        client.assign_attributes(:nearest_project_start => self.task_start_date, :nearest_project_id => self.project_id) if self.task_start_date < client.nearest_project_start     
    else
        client.assign_attributes(:nearest_project_start => self.task_start_date, :nearest_project_id => self.project_id)
    end
    if client.furthest_project_end.present?
        client.assign_attributes(:furthest_project_end => self.task_end_date, :furthest_project_id => self.project_id) if self.task_end_date > client.furthest_project_end
    else
        client.assign_attributes(:furthest_project_end => self.task_end_date, :furthest_project_id => self.project_id)
    end
    client.save
end

它很混乱，但它在应用程序中运行。

Client有许多Projects，其中包含许多Tasks和Client has many Tasks through Projects

然而，当我尝试播种数据库时，我看到的输出类似于：

这似乎是在拉客户端而不是更新记录？（不确定如何测试这个理论）。

然后我进入了应用程序并创建了一个客户端 - ＆gt;项目 - ＆gt;作为用户的任务和所有记录看起来就像我期望的那样，但似乎Seeding忽略了这个功能，但是它正在更新Project部分。

种子档案

task_list = [
  ['Task 1', 'Nothing to add', '2017-09-01', '2018-01-01', 1, 1, 0],  
  ['Task 3', 'Nothing to add', '2017-08-01', '2017-10-01', 1, 2, 1],
  ['Task 4', 'Nothing to add', '2017-06-01', '2017-09-01', 1, 3, 1],
  ['Task 5', 'Nothing to add', '2017-11-01', '2017-12-01', 1, 4, 0],
  ['Task 6', 'Nothing to add', '2017-08-01', '2018-02-01', 1, 5, 0],
  ['Task 7', 'Nothing to add', '2017-08-01', '2017-12-01', 1, 6, 0],
  ['Task 8', 'Nothing to add', '2017-11-01', '2017-12-15', 1, 7, 0],
  ['Task 9', 'Nothing to add', '2017-07-01', '2017-08-15', 1, 1, 0],
  ['Task 17', 'Nothing to add', '2017-04-01', '2017-08-01', 1, 6, 1],
  ['Task 28', 'Nothing to add', '2017-08-01', '2017-10-01', 1, 7, 0],
  ['Task 39', 'Nothing to add', '2018-01-01', '2018-04-01', 1, 1, 1]
]

task_list.each do |name, comment, start, end_date, project, product, completed|
  dproject = Project.find(project)
  dproject.tasks.create!(task_name: name, comment: comment, task_start_date: start, task_end_date: end_date, project_id: project, product: product, completed: completed)
  puts name
end

我原本没有项目分配线，但我看到是否解决了MIA客户端的详细信息。

如果创建了一个任务，并且其日期end_date比客户的furthest_project_end日期字段晚，则应更新该字段。目前尚未更新。然而，它正在更新project.end_date
