Ruby：开始事务，回滚事务
新的ruby，我面临一个小问题……需要一双新鲜的眼睛
fyi：我没有使用脚手架，所以我可以理解在ruby中建造的一步一步的过程。
当我尝试添加新的gig时，它不会保存在数据库上，我在服务器日志中看到以下错误…

Post an Internship Opportunity

这是我的演出控制器
class GigsController < ApplicationController def index end def new @gig = Gig.new end def create @gig = Gig.new(gig_params) @gig.save redirect_to @gig end #private stuff private def gig_params params.require(:gig).permit(:name, :description, :budget, :startdate, :duration, :location, :open, :hired ) end end
如果我添加我的架构，感觉可能会有所帮助？
create_table "gigs", force: :cascade do |t| t.string "name" t.text "description" t.integer "budget" t.date "startdate" t.integer "duration" t.string "location" t.boolean "open", default: true t.integer "hired" t.datetime "created_at", null: false t.datetime "updated_at", null: false t.integer "category_id" t.integer "user_id" t.index ["category_id"], name: "index_gigs_on_category_id" t.index ["user_id"], name: "index_gigs_on_user_id" end
添加Gig模型也是如此
class Gig < ActiveRecord::Base has_many :proposals belongs_to :user belongs_to :category has_many :abilities has_many :skills, through: :abilities end
问题似乎在validation中，您可以通过执行以下操作来检查：
首先，转到rails app目录并执行：
rails console
接下来，创建一个新的gig实例：
g = Gig.new(name: "Perry Dillard", budget: "500") #Add all the fields
测试是否有任何validation失败
g.valid?
如果返回false，则有一些停止保存的validation。 问题是什么：
g.errors.messages
这应该给你validation的消息。
您正在尝试保存记录，但未通过某些validation。 您应该检查Ruby on Rails指南中的Active Record Validations 。 你也可以尝试打印@gig.errors来看看什么是失败的。
