我认为我拥有能够发送嵌套属性的所有这些设置，但是，我不断收到 422 无法处理的实体，但没有错误消息。以下是我的配置方式：

scouting_report.rb

class ScoutingReport < ApplicationRecord
    has_many :scouting_report_details
    accepts_nested_attributes_for :scouting_report_details, :allow_destroy => true
end

scouting_report_detail.rb

class ScoutingReportDetail < ApplicationRecord
    belongs_to :scouting_report
end

scouting_reports_controller.rb

def scouting_report_params
  params.require(:scouting_report).permit(
    :customer_id, 
    :report_date, 
    :crop_id, 
    :wind_speed, 
    :wind_speed_direction, 
    :wind_speed_degree, 
    :temperature, 
    :sky, 
    :crop_growth_stage, 
    :crop_condition_comments, 
    :stand_count, 
    :irrigation_comment, 
    :crop_water_use, 
    :crop_water_use_units, 
      scouting_report_details_attributes: [
        :id, 
        :action, 
        :disorder_id, 
        :disorder, 
        :identifiaction, 
        :lon, 
        :level, 
        :lat, 
        :scouting_report_id])
end

以下是数据在架构中的外观：

  create_table "scouting_reports", force: :cascade do |t|
    t.integer  "customer_id"
    t.datetime "created_at",              null: false
    t.datetime "updated_at",              null: false
    t.datetime "report_date"
    t.integer  "crop_id"
    t.string   "wind_speed"
    t.string   "wind_speed_direction"
    t.string   "wind_speed_degree"
    t.string   "temperature"
    t.string   "sky"
    t.string   "crop_growth_stage"
    t.text     "crop_condition_comments"
    t.string   "stand_count"
    t.text     "irrigation_comment"
    t.string   "crop_water_use"
    t.string   "crop_water_use_units"
  end

  create_table "scouting_report_details", force: :cascade do |t|
    t.string   "disorder"
    t.integer  "disorder_id"
    t.string   "level"
    t.string   "action"
    t.string   "identifiaction"
    t.string   "lat"
    t.string   "lon"
    t.datetime "created_at",         null: false
    t.datetime "updated_at",         null: false
    t.integer  "scouting_report_id"
  end

日志报告 422，但没有错误：

        "crop_condition_comments" : "Comment about the conditions",
        "crop_id" : "1234"
    }
}

只是需要另一双眼睛。我确定我只是缺少一些简单的东西。

尝试添加inverse_of您的关联：

class ScoutingReport < ApplicationRecord
  has_many :scouting_report_details, inverse_of: :scouting_report
end

class ScoutingReportDetail < ApplicationRecord
  belongs_to :scouting_report, inverse_of: :scouting_report_details
end
