我有兩個域類:驗證錯誤在域的建模,Grails的

用戶

class User { 
    String login 
    String password 

    static belongsTo = [company: Company] 
    static hasMany = [holidays: Holiday] 

    static constraints = { 
     company(nullable:false) 
    } 
} 

公司

class Company { 
    String shortName; 
    String name 
    Date dateCreated 
    String region 
    String email 
    Address address 
    Status status 
    Long tel 
    Long fax 

    static hasMany = [ users : User] 

    static constraints = { 
     name(nullable:false, size:6..20, unique:true) 
     shortName(size:2..10, nullable: true, unique:true) 
     region(nullable: true) 
     email(email:true) 
     tel(nullable: false, blank:false) 
     fax(blank:false) 
     address(nullable: false) 
     status(nullable: false) 
     users(nullable:true) 
    } 

    static mapping = { 
     address lazy: false 
     status lazy: false 
    } 
} 

我已經定義了一個一對多關係在UserCompany之間。如果我寫這樣的測試:

void testCompanyHasManyUser() { 
    def user1 = new User(login:"anto", password:"secret") 
    assert user1.save(failOnError: true) 
    def company1 = new Company(shortName:"helloworld",name:"helloasd",region:"chennai", 
     email:"[email protected]",tel:23234,fax:343343, address: new 
     Address(country:"india",city:"chennai",street:"thayarst",code:"1233"), 
     status: new Status(name:"FIXED")) 
    assert company1.save() 
    company1.addToUsers(user1) 
} 

當我跑我得到的錯誤是這樣的測試:

Validation Error(s) occurred during save(): - Field error in object 'mnm.User' on field 'company': rejected value [null]; codes [mnm.User.company.nullable.error.mnm.User.company,mnm.User.company.nullable.error.company,mnm.User.company.nullable.error.mnm.Company,mnm.User.company.nullable.error,user.company.nullable.error.mnm.User.company,user.company.nullable.error.company,user.company.nullable.error.mnm.Company,user.company.nullable.error,mnm.User.company.nullable.mnm.User.company,mnm.User.company.nullable.company,mnm.User.company.nullable.mnm.Company,mnm.User.company.nullable,user.company.nullable.mnm.User.company,user.company.nullable.company,user.company.nullable.mnm.Company,user.company.nullable,nullable.mnm.User.company,nullable.company,nullable.mnm.Company,nullable]; arguments [company,class mnm.User]; default message [Property [{0}] of class [{1}] cannot be null] 
grails.validation.ValidationException: Validation Error(s) occurred during save():

    at mnm.UserIntegrationTests.testCompanyHasManyUser(UserIntegrationTests.groovy:21) 

我知道我在validation部分犯了一個錯誤。儘管我保存了company對象,但錯誤顯示user.save失敗。爲什麼?我哪裏做錯了?

問題看起來像是你說用戶必須有一家公司,然後創建一個沒有公司的用戶並嘗試保存它。

嘗試調用

assert user1.save(failOnError: true) 

但是之前設置一個公司,你已經顯示了testCompanyHasManyUser的考驗,從testUserAddingHoliday錯誤,所以這是很難確定

對不起已經編輯它 –

酷的問題依然存在,因爲你有一個驗證公司(可空:false),你不能保存沒有公司的用戶。要麼放寬驗證,或者如果它是正確的,在將用戶保存在測試 –

Ya中之前將該公司添加到用戶中,現在它可以工作。我感到困惑的是驗證部分,即使我刪除驗證「公司(可空:false)」部分,我也得到了和以前一樣的錯誤。任何想法爲什麼它出錯了? –
