【中文标题】Grails 从 2.4.5 升级到 3.3.2:关系“xxx”不存在【英文标题】:Grails upgrade from 2.4.5 to 3.3.2: Relation 'xxx' does not exist 【发布时间】:2018-02-23 13:10:53 【问题描述】:

将 Grails 2.4.5 升级到 3.3.2 项目是否需要进行数据库迁移。目前,我在 Bootstrap.groovy 中遇到问题,应用程序无法启动。

ERROR: Relation "department" does not exist

编辑: 部门标签:

class DepartmentTag 
String name
String details
static constraints = 

static belongsTo = [department : Department]
 

部门域类:

class Department 
String name
String address
String postalCode=''
String phoneNumber=''
String email=''
String homeCounty=''
Float latitude
Float longitude
List speciality

static constraints = 
    homeCounty defaultValue: 'XXX'
    email nullable:true, defaultValue: ''
    phoneNumber nullable:true
    address nullable:true
    postalCode nullable:true
    homeCounty nullable:true
    latitude nullable:true, scale:6
    longitude nullable:true, scale:6
    speciality nullable: true      

static mapping = 
    vacancy lazy: false


static belongsTo = [company: Company]

static hasMany = [  speciality: String, tags : DepartmentTag,  comments:Comment, phoneContacts:PhoneContact, ipAddresses: IPAddress]  
static hasOne =  [ vacancy : Vacancy ]

类引导程序

def init =  servletContext ->
    // Check whether the test data already exists.
    def openTag = new DepartmentTag(name:"name1", details:"details1").save(failOnError:true)
    def terTag = new DepartmentTag(name:"name2", details:"details2").save(failOnError:true)       
    
   if(!Company.count()) 
        new Company(name: "company1", phoneNumber: "+12345", address: "address1", postalCode: "12345", email: "testi@testi.com", homeCounty: "XXX").save(failOnError: true)
                .addToDepartment(new Department(name: "department_name", speciality: ["speciality1", "speciality2"], address: "address1", postalCode: "12345", homeCounty: "XXX", phoneNumber: "12345", email: "testi@testi.com", vacancy: new Vacancy(maleVacancy: 4, femaleVacancy: 4, specialVacancy: 2)).addToTags(terTag)).save(failOnError: true)

公司域类:

【问题讨论】:

发生这种情况的原因有很多。你能展示有问题的BootStrap 代码和相关的域类吗? @JeffScottBrown 编辑了我的问题 【参考方案1】:

大概您同时从 Hibernate 4 更新到 5? Hibernate 5 目前存在生成外键不同的问题:https://hibernate.atlassian.net/browse/HHH-10574

我不确定这是您看到的问题,但可能与此有关。即使没有,也需要注意。

【讨论】:

【参考方案2】:

问题在于表中的默认值。从 Grails 社区获得帮助,执行 grails schema-export,从空数据库开始并执行 ddl.sql.
