Question

我有以下要求：模型叫医疗;它有医生类型和治疗类型;可以为医学模型选择多种医生类型和治疗类型。

我试图避免为医生类型和治疗类型创建模型。它们基本上是应用程序为其用户提供的集合。我试图将它们作为hstore字段存储在Medical模型中。

我做了以下......

为hstore添加了迁移：

   class AddHstore < ActiveRecord::Migration 
    def up
     enable_extension :hstore
    end

    def down
     disable_extension :hstore
    end
  end

添加了迁移以添加hstore字段：

class AddDataToMedical < ActiveRecord::Migration
  def change
    add_column :medical, :data, :hstore
  end
end

在模型中添加了以下内容：

class Medical < ActiveRecord::Base

    DOCTOR_TYPE = ['MD', 'Specialist', 'DO', 'Other']
    TREATMENT_TYPE = ['PT', 'Chiro', 'Meds', 'Other']

    store_accessor :data, :doctor_type, :treatment_type
...

在strong_params中添加了以下内容：

 # Never trust parameters from the scary internet, only allow the white list through.
def medical_params
  params.require(:medical).permit(:total_med_bills, :subrogated_amount, :injuries_within_three_days, :length_of_treatment, 
                              :length_of_treatment_unit, :injury_summary, :medical_summary, 
                              :earnings_lost, :treatment_gap, :injections, :hospitalization, :hospital_stay_length, 
                              :hospital_stay_length_unit, :data => [:doctor_type, :treatment_type], :injuries_attributes => [:injury_type, :region, :code, :dominant_side, :joint_fracture,
                              :displaced_fracture, :disfigurement, :impairment, :permanence, :disabled,
                              :disabled_percent, :surgery, :surgery_count, :surgery_type, :casted_fracture,
                              :stitches, :future_surgery, :future_medicals, :id])

end

然后将新字段添加到表单中：

<%= simple_form_for([@case, @medical]) do |f| %>
    <%= f.input :total_med_bills %>
    <%= f.input :length_of_treatment %>
    <%= f.simple_fields_for :data do |d| %>
      <%= d.input :doctor_type, as: :check_boxes, collection: Medical::DOCTOR_TYPE %>
      <%= d.input :treatment_type, as: :check_boxes, collection: Medical::TREATMENT_TYPE %> 
    <% end %>
    <%= f.input :injury_summary %>
...

问题是当我在medicals_controller的Update方法中执行put params [：data]时，为什么数据参数为空（我只在编辑中使用此字段）？另外，为什么我在我的控制台中获得以下内容：

Unpermitted parameters: doctor_type, treatment_type

当我查看我的控制台时，我发现数据哈希不是空的：

..."length_of_treatment"=>"", "data"=>{"doctor_type"=>["MD", "Specialist", ""], "treatment_type"=>["Meds", "Other", ""]}, "injury_summary"=>"",...

由于强参数不允许强参数中的标量值...我最终执行了以下操作...

强参数：

... :data => [:doctor_type => [], :treatment_type => []] ...

doctor_type和treatment_type个键可以有多个值。

如何在表单中使用hstore数据类型字段并在Rails 4中存储在数据库中？
