未定义方法'halt_callback_chains_on_return_false=

    我正在将rails 5.1应用程序升级到5.2。我已经更新了所有的gems,包括rails,最后运行 rails app:update 它为我的rails应用程序创建了新文件。

    具体来说,有两个文件是我创建的。首先在 config/initializers 有一个 new_framework_defaults_5_2.rb 文件和第二个(在同一目录中)a new_framework_defaults.rb . 第一个文件只包含注释,但第二个文件包含一些新的配置选项。其中一个选择是: 

    ActiveSupport.halt_callback_chains_on_return_false = false

    此方法调用引发未定义的方法错误。我需要对这行代码做些什么?

    这是StackTrace:

    上次从5.1升级到5.2时,我遇到了同样的问题。 我所做的只是在 config/initializers/new_framework_defaults.rb 

    # Do not halt callback chains when a callback returns false. Previous versions had true.
# ActiveSupport.halt_callback_chains_on_return_false = false

    我想引起这个错误的原因是 halt_callback_chains_on_return_false 选项实际上是根据 this release note .

    这是以前的行为: 

    WelcomeController < ApplicationController
  before_action: -> { return false }

  def index
    # would not be called
  end
end

    什么 halt_callback_chains_on_return_false = false 做: 

    WelcomeController < ApplicationController
  before_action: -> { return false }

  def index
    # would now be rendered regardless of the before_action filter chain's return value
  end
end

    rails认为应该在过滤器链中做什么来防止渲染: 

    WelcomeController < ApplicationController
  before_action: -> { raise 'Error' }

  def index
    # would not be rendered
  end
end

    希望这有帮助。

    最好的, 埃米尔

      halt_callback_chains_on_return_false setting in the initializer

    这是一个在升级到rails 5.0之后临时保留旧回调行为的解决方案。假设您需要时间检查应用程序中的所有回调,然后您可以删除此设置。并假定升级到5.2时已选中“全部”,因此将删除此设置。

    只要按照@worrawut在 config/initializers/new_framework_defaults.rb文件。
