我使用的是一个现有的外部数据库,它的主键集为floating/double。除编辑操作外,所有操作都可以正常工作。

它给出的错误是这样的。 有没有办法解决这个问题,或者将其更改为int是唯一的方法?

没有与[获取]“/subsystem\u tbls/'1.123'/编辑”匹配的路由

路线。rb型

Rails.application.routes.draw do
  root "subsystem_tbls#index"
  resources :subsystem_tbls
  resources :ui_types_tbls
  resources :cmd_types_tbls
end

控制器

class SubsystemTblsController < ApplicationController
  def index
    @subs = SUBSYSTEM_TBL.all
  end

  def new
    @subs = SUBSYSTEM_TBL.new
  end

  def show
    @subs = SUBSYSTEM_TBL.find_by(params[:SUBSYSTEM_ID])
  end

  def edit
    @subs = SUBSYSTEM_TBL.find_by(params[:SUBSYSTEM_ID])
  end

  def create
    @subs = SUBSYSTEM_TBL.new(sub_params)
    if @subs.save
      redirect_to @subs
    else
      render 'new'
    end
  end

  def update
    @subs = SUBSYSTEM_TBL.find_by(params[:SUBSYSTEM_ID])
    if @subs.update_attributes(sub_params)
      redirect_to root_url
    else
      render 'edit'
    end
  end

  def destroy
    SUBSYSTEM_TBL.find_by(params[:SUBSYSTEM_ID]).destroy
    redirect_to root_url
  end

  private

  def sub_params
    params.require(:subsystem_tbl).permit(:SUBSYSTEM_ID, :SUBSYSTEM_NAME)
  end
end
