active_admin嵌套表单的不允许参数

Question

我在活动管理资源中使用嵌套形式，但是嵌套属性值不在模型中保存。

这是我模特的细节-

class Exceed::Assessment < ActiveRecord::Base

    has_many :assessment_infos, :class_name => "Exceed::AssessmentInfo", :dependent => :destroy
    accepts_nested_attributes_for :assessment_infos, allow_destroy: true

end

下一种模式-

class Exceed::AssessmentInfo < ActiveRecord::Base

    belongs_to :assessment

end

以下是Exceed：：active的活动管理资源

ActiveAdmin.register Exceed::Assessment do

  form do |f|
    f.inputs "Exceed Details" do
      f.input :exceed_id, :label => 'Exceed Type', :as => :select, :collection => Exceed.all.map{|s| ["#{s.exceed_type}", s.id]}
      f.input :exceed_section_id, :label => 'section', :as => :select, :collection => ExceedSection.all.map{|s| ["#{s.section}", s.id]}
      f.input :guideline, label: "Section Guideline"   
    end
    f.has_many :assessment_infos do |q|
      q.input :information
    end
    f.actions
  end

  controller do
    def permitted_params
      params.permit exceed_assessment: [:exceed_id, :exceed_section_id, :guideline],
      assessment_infos_attributes: [:information]
    end
  end


end

从我的活动管理表单中，我填写了exceed_assessment和嵌套表单assessment_info的详细信息。Exceed_assessment详细信息在模型中成功保存，但assessment_info没有保存。当我在控制台上检查它时它会显示错误信息-

Unpermitted parameters: assessment_infos_attributes
Unpermitted parameters: utf8, authenticity_token, commit

Answer 1

我犯了一些愚蠢的错误，纠正了它们的工作。

首先，在我的Assessment_info模型中有一个列‘exceed_ Firstly _id’。我将其改为“assessment_id”，因为我的模型是belongs_to评估模型。

第二，我稍微改变了许可参数的语法，像这样-

controller do
    def permitted_params
      params.permit exceed_assessment: [:id, :exceed_id, :exceed_section_id, :guideline,
      assessment_infos_attributes: [:assessment_id, :information],]
    end
  end
