Question

我正在开发一个使用Rails前端将更新数据发送到Rails后端的项目。

我正在尝试修补的表单数据包括资源的更新数据，以及嵌套的子资源的更新。

在这种情况下，用户与包含编写数据的表单进行交互，编写器具有许多作业，所有作业也嵌套在表单中。

数据包含作者，一个/多个/所有作者作业或两者的潜在更新。

writer.rb

class Writer < ApplicationRecord
   has_many :jobs, dependent: :destroy, inverse_of: :writer
   has_many :genre_tags, dependent: :destroy
   has_many :genres, :through => :genre_tags

   accepts_nested_attributes_for :genre_tags, allow_destroy: true, reject_if: :all_blank
   accepts_nested_attributes_for :jobs, allow_destroy: true, reject_if: :all_blank
end

job.rb

class Job < ApplicationRecord
   belongs_to :writer, inverse_of: :jobs
   validates_uniqueness_of :outlet_id, scope: [:writer_id]
   validates :outlet_id, presence: true
end

writers_controller.rb

 def update
   @writer = Writer.where(inactive:false).find(params[:id])

   if @writer.update(writer_params)
     render json: {writer: @writer, notice: 'Writer was successfully updated.'}
   else
     render json: {errors:Rails.logger.info(@writer.errors.inspect), status: :unprocessable_entity }
   end

   def writer_params
     params.require(:writer).permit(:f_name,:l_name, :email_personal, :city, :state, :country_id,:twitter, :linkedin, :freelance, :notes, :user_id, jobs_attributes: [:id, :outlet_id, :email_work, :position, :outlet_profile, :key_contact, :_destroy, presstype_tags_attributes: [:id, :presstype_id, :_destroy]], genre_tags_attributes: [:id, :writer_id, :genre_id, :_destroy])
   end

end

问题在于，当我修补此数据时，我收到验证错误：

#<ActiveModel::Errors:0x007fef651e8410 @base=#<Writer id: 2, f_name:  "Chet", l_name: 
"Hamper", city: "Las Vegas", state: "NV", country_id: 229, 
twitter: "AndreasHale", linkedin: "andreashale", 
freelance: false, flagged: nil, inactive: false, 
notes: nil, created_at: "2017-02-19 15:38:55", 
updated_at: "2017-02-25 16:17:18", user_id: 1, 
email_personal: nil, twitter_followers: nil, 
personal_website: "N/A">, 
@messages={:"jobs.presstype_tags.job_id"=>["can't be blank"],
:"jobs.outlet_id"=>["has already been taken"], 
:"genre_tags.genre_id"=>["has already been taken"]}, 
@details={"jobs.presstype_tags.job_id"=>[{:error=>:blank}], "jobs.outlet_id"=>[{:error=>:taken, :value=>2}], 
"genre_tags.genre_id"=>[{:error=>:taken, :value=>6}, {:error=>:taken, :value=>9}, {:error=>:taken, :value=>10}, {:error=>:taken, :value=>11}]}>

除非我弄错了，否则ActiveRecord告诉我我正在尝试创建新的嵌套属性，即使它们已经存在。我不是要覆盖这些记录，只是当它们存在时，更新它们的属性。

有关我如何指定我不想覆盖任何内容的任何线索？

更新

事实证明我的表单数据的结构与jobs_attributes，genre_tags_attributes和presstype_tags_attributes params不匹配，所以我最终重组了我的表单以完全匹配它，现在它就像一个魅力！

Rails无法更新嵌套的子资源？
