回调无效

Question

我有两个回调在我的模型中无效。它们也不会引发任何错误消息。

第一个回调是：after_update :state_closed当我从“已解决”或“已取消”视图中选择票证状态时，我想使用它来关闭票证。所以，我想在这种情况下关闭

第二个回调是after_create :assign_state，我想使用它来说明故障单已分配或未分配，因此如果employee_id为空，则表示该故障单尚未分配给任何员工。如果employee_id不是黑色，则分配此票证

这是我的ticket.rb

class Ticket < ActiveRecord::Base
  before_save :default_values
  after_update :state_closed
  after_create :assign_state

  attr_accessible :description, :title, :employee_department_id, :user_id, :first_name,
:last_name , :email, :state_id, :employee_id, :ticket_state, :assign_state


  belongs_to :employee_department
  belongs_to :user
  belongs_to :state
  belongs_to :employee

  has_many :replies

  def default_values
    self.state_id = 3 if self.state_id.nil?
  end

  def to_label
    ticket_state.to_s
  end

  def state_closed
    if self.ticket_state == "Solved" || self.ticket_state == "Canceled"
      self.ticket_state = "Closed"
      self.save
    end
  end

  def assign_state
    if self.employee_id.nil?
      self.assign_state = "Un-assigned"
    else
      self.assign_state = "Assigned"
    end
  end

  Ticket.all.each do |ticket|
    if ticket.ticket_state.blank?
      ticket.ticket_state = 'open'
    end
    ticket.save
  end
  ...

这是来自服务器日志，当我选择“已解决”时，例如如果我的回调正在工作则更新为“已解决”，那么在这种情况下它应该从已解决变为已关闭但未发生

Answer 1

每个问题如下：

由于资本化问题，

state_closed未被调用：“已解决”不等于“已解决”。更改大写以匹配，或者比较字符串在它们都是低级时。

assign_state可能正在被调用，但不会持续存在，因为一旦模型发生变化，你就永远不会保存模型。在create。更新后尝试保存。
