【中文标题】表单字段被拒绝，我不知道为啥【英文标题】：Form field is being rejected and I can not figure out why表单字段被拒绝，我不知道为什么 【发布时间】：2021-12-24 00:51:27 【问题描述】：嗯，希望这个问题很清楚。
我有一个旧应用程序要移植到 Rails 5。
我有一个使用特殊方法“create_shift”来处理它的表单，它在下面指示的行中断（注意：create_shift 是我要移植的原始代码的一部分）...我已经包含了控制台错误尝试后的消息...
这是错误...
vs.attributes=(assignment_params) #fixme: if i try this line I get...
# ActiveModel::UnknownAttributeError: unknown attribute 'contact_id' for VolunteerShift.

这是表格...

end
end
vs = ve.volunteer_shifts.new

def assignment_params
params.require(:assignment).permit(:action, :controller, :title, :set_date, :date, :date_range, :volunteer_shift_id, :contact_id, :start_time, :end_time, :start, :end, :attendance_type_id, :notes, :call_status_type_id, :closed, :lock_version, :color, :description, :contact_element_prefix, :lock_versions, :commit, volunteer_shift_attributes: [:volunteer_task_type_id,:roster_id,:program_id,:set_description,:id, :destroy])

这甚至是模型关联
class Assignment < ApplicationRecord
# attr_accessor :volunteer_event ,:contact_id #why is this here???
# attr_accessor :redirect_to
belongs_to :volunteer_shift
has_one :volunteer_task_type, :through => :volunteer_shift, :source => :volunteer_task_type
belongs_to :contact ,optional: true
validates_presence_of :volunteer_shift #belongs_to takes care of this now
validates_associated :volunteer_shift
belongs_to :attendance_type
belongs_to :call_status_type
validates_presence_of :set_date, :if => :volshift_stuck #belongs_to takes care of this now??

delegate :set_date, :set_date=, :to => :volunteer_shift

...
end
class VolunteerEvent < ApplicationRecord
belongs_to :volunteer_default_event
validates_presence_of :date
has_many :volunteer_shifts, :dependent => :destroy
has_many :resources_volunteer_events, :dependent => :destroy
validates_associated :volunteer_shifts
...
end
class VolunteerShift < ApplicationRecord
validates_presence_of :roster_id
validates_presence_of :end_time
validates_presence_of :start_time
has_many :assignments
belongs_to :volunteer_default_shift
belongs_to :volunteer_task_type
belongs_to :roster
belongs_to :volunteer_event
belongs_to :program
has_many :contact_volunteer_task_type_counts, :primary_key => 'volunteer_task_type_id', :foreign_key => 'volunteer_task_type_id' #:through => :volunteer_task_type
...
end
我希望这不会太混乱。所以看起来代码在......
vs.attributes=(assignment_params) #fixme: if i try this line I get...
# ActiveModel::UnknownAttributeError: unknown attribute 'contact_id' for VolunteerShift.
# from /home/fonso/.rbenv/versions/2.5.8/lib/ruby/gems/2.5.0/gems/activemodel-5.0.7.2/lib/active_model/attribute_assignment.rb:48:in `_assign_attribute'
所以我想知道...如何让 contact_id 注册？
不确定这是否有帮助，但我会添加它。它接收的参数看起来像这样......
> [2] pry(#<VolunteerEventsController>)> params
> => <ActionController::Parameters "utf8"=>"✓", "assignment"=><ActionController::Parameters
> "volunteer_shift_attributes"=><ActionController::Parameters
> "volunteer_task_type_id"=>"41", "roster_id"=>"7", "program_id"=>"9",
> "set_description"=>"so sick of this database" permitted: false>,
> "set_date"=>"2021-01-11", "start_time(1i)"=>"2021",
> "start_time(2i)"=>"11", "start_time(3i)"=>"11",

> "end_time(4i)"=>"09", "end_time(5i)"=>"00", "notes"=>"Fonso in Matrix
> Nov", "contact_id"=>"166574", "closed"=>"0", "lock_version"=>"0"
> permitted: false>, "contact_element_prefix"=>"contact",
> "commit"=>"Submit", "controller"=>"volunteer_events",
> "action"=>"create_shift" permitted: false> [3]
> pry(#<VolunteerEventsController>)>
较旧的应用程序没有 strong_params，因此这不是问题。但我怀疑旧应用中的 contact_id 周围有一些奇怪的编码。
我该怎么做才能让这条线与contact_id一起工作......
vs.attributes=(assignment_params)
...或者至少是预期的结果？
是否应该将某种用于contact_id 的attr_accessor 放置在volunteer_shift 模型中或更高级别？
我可以使用一些奇怪的 hack 或 rails 魔法吗？大声笑，这听起来很疯狂，但我怀疑这可能是旧应用程序所做的。
如果我需要在这篇文章中添加任何内容，例如模型关联、视图或其他任何内容，请告诉我，我很乐意提供帮助。
感谢您的宝贵时间。
更新：
现在，如果我像这样重写 params 方法...
def volunteer_event_params
> params.require(:volunteer_event).permit(:action, :controller, :title, :set_date, :date, :date_range, :volunteer_shift_id,
> :contact_id, :start_time, :end_time, :start, :end,
> :attendance_type_id, :notes, :call_status_type_id, :closed,
> :lock_version, :color, :description, :contact_element_prefix,
> :lock_versions, :commit, volunteer_shift_attributes:
> [:volunteer_task_type_id,:roster_id,:program_id,:set_description,:id,
> :destroy])
end
我收到此错误
ActionController::ParameterMissing - param is missing or the value is empty: volunteer_event:
用 Pry 挖掘，我知道我得到了这些参数...
> [1] pry(#<VolunteerEventsController>)> params
> => <ActionController::Parameters "utf8"=>"✓", "assignment"=><ActionController::Parameters
> "volunteer_shift_attributes"=><ActionController::Parameters
> "volunteer_task_type_id"=>"41", "roster_id"=>"7", "program_id"=>"9",

【问题讨论】：
【参考方案1】：所以要在这种情况下“修复”这个问题（通过将代码移植到 Rails 5.0 应用程序来升级旧的 Rails 2.x 应用程序）
强参数轮换：
config.action_controller.permit_all_parameters = true
在此处了解更多信息...https://guides.rubyonrails.org/v5.0/configuring.html
