Question

我有一个表格，其中包含2个专业的嵌套表格（证书和培训）。每个人在Professional模型中都有关联accepted_nested_attributes_for。我可以凭他的证书和培训创建一个新的专业人士。但是，当我保存时，不是更新证书和培训，而是创建一个新证书。

我的专业控制员：

def edit
  @professional = Professional.find(params[:id])
  @component = Component.all
  cert = Certificate.where('professional_id = ?', params[:id])
  cert.each do |certificate|
    @certificate = certificate
  end
  tra = Training.where('professional_id = ?', params[:id])
  tra.each do |training|
    @training = training
  end
  @work = Work.all
  @charge = Charge.all
  @entities =Array.new
  TypeEntity.where("id IN (1,5)").each do |tent|
    @entities << tent.entities
  end
  @reg = Time.now.to_i.to_s
  @major = Major.all
  @action = 'edit'
  render layout: false
end

def update
  profesional = Professional.find(params[:id])
  if profesional.update_attributes(professional_parameters)
    flash[:notice] = "Se ha actualizado correctamente los datos."
    redirect_to :action => :index
  else
    profesional.errors.messages.each do |attribute, error|
      flash[:error] =  flash[:error].to_s + error.to_s + "  "
    end
    # Load new()
    @profesional = profesional
    render :edit, layout: false
  end
end

private
def professional_parameters
  params.require(:professional).permit(
    :name,
    :dni, 
    :professional_title_date, 
    {:major_ids => []}, 
    :date_of_tuition, 
    :code_tuition, 
    :professional_title, 
    :tuition, 
    :cv, 
    certificates_attributes: [
      :id, 
      :professional_id, 
      :work_id, 
      :charge_id, 
      :entity_id, 
      :num_days, 
      :start_date, 
      :finish_date, 
      {:component_work_ids => []}, 
      :certificate, 
      :other, 
      :_destroy
    ], 
    trainings_attributes: [
      :id, 
      :professional_id, 
      :type_training, 
      :name_training,
      :num_hours, 
      :start_training, 
      :finish_training, 
      :training, 
      :_destroy
    ]
  )
end

这是模特：

class Certificate < ActiveRecord::Base
  has_one :charge
  belongs_to :professional
end

class Professional < ActiveRecord::Base
  has_and_belongs_to_many :majors
  has_many :certificates
  has_many :trainings
  accepts_nested_attributes_for :certificates, :allow_destroy => true
  accepts_nested_attributes_for :trainings, :allow_destroy => true
end

class Training < ActiveRecord::Base
  belongs_to :professional
end

表单以此开头：

=simple_form_for([:biddings, @professional], html: { multipart: true }) do |f|

之后我在引导向导中有3个表单。

Answer 1

确保ID表单中的Hash中包含Edit个属性。由于您的模型具有一对多，

   For each hash that does not have an id key a new record will be instantiated, unless 
   the hash also contains a _destroy key that evaluates to true.

嵌套表单不是更新，而是创建一个新的Rails
