获取父数据数组列表

我有这样一个域名...获取父数据数组列表

class Invoice { 

    String invoiceNo 
    Date invoiceDate 
    Date dueDate 
    BigDecimal totalAmount 

    Date sendDate 
    Customer customer 
    String fromSOorDO   

    static mapping = { 
     //formula to calculate dueDate (invoiceDate + tempo) 
     dueDate formula:"ADDDATE(invoice_date, tempo)" 
    } 

    static constraints = {   
    } 

}

我需要从域invoice所有数据传递到Array List与parent的名称，而不是id。

例如，从域invoice，我们可以看到Customer customer。

当我们从数据库中看到，现场customer是id像1，2，3其中属于表Customer。

这是客户的域名。

class Customer { 
    String code 
    String name 
    String address 
    String phoneNo 

    static constraints = {} 
}

我需要将所有数据通过发票成ArrayList其中Customer的id替换Customer的name ..

实施例的数据：

表invoice具有customer = 1

行

然后表客户这样：

id | code | name | address| phoneNo| 
1 | A |aaaaaa| Street |123132 | 
2 | B |bbbbbb| Street |454545 |

当我检索域invoice与customer的字段显示为客户的名称并将其填充到哈希映射。

def invoice = c.list(params) { 
    ge("invoiceDate", dateFrom) 
    eq("deleteFlag", "N") 
    eq("cif", cif) 
} 

def map = new HashMap() 
map.put("invoiceList",invoice)

我试图用collect喜欢这一点，并得到这个错误：

def c = Invoice.createCriteria() 
    def invoice = c.list(params) { 
     ge("invoiceDate", dateFrom) 
     eq("deleteFlag", "N") 
     eq("cif", cif) 
    }.collect{ invoice -> 
     invoice.properties.collect{ it } + [customer:invoice.customer.name] 
    }

你真的认为我们需要查看您的域类的所有属性？包括那些，评论一些巨型巨无霸？ – injecteer

@injecteer完成 – akiong

你有2个选择这里：

1）收集客户的名称代码：

def invoice = c.list(params) { 
    ge("invoiceDate", dateFrom) 
    eq("deleteFlag", "N") 
    eq("cif", cif) 
}.collect{ invoice -> invoice.properties.collect{ it } + [ customer:invoice.customer.name ] }

2）使用projection：

def invoice = c.list(params) { 
    projections { 
     property 'invoiceNo' 
     property 'invoiceDate' 
     // other properties 
     customer { 
      property 'name' 
     } 
    } 
    ge("invoiceDate", dateFrom) 
    eq("deleteFlag", "N") 
    eq("cif", cif) 
}

注意，在这两种情况下，你得到Map小号的实例，而不是你的Invoce对象列表

是的，这一个...我喜欢它，谢谢.. – akiong

如果我想通过更多，不仅客户，然后这样？ '.collect {invoice - > invoice.properties.collect {it} + [customer：invoice.customer.name，customer2：invoice.customer2。}' – akiong

我试着用'collect'使用你的解决方案，看到我更新的问题 – akiong

尝试这样的..

def c = Invoice.createCriteria() 
    def invoice = c.list(params) { 
     createAlias('customer','customer') 
     projections { 
      property ('invoiceNo','invoiceNo') 
      property ('invoiceDate','invoiceDate') 
      property ('dueDate','dueDate') 
      property ('totalAmount','totalAmount') 
      property ('sendDate','sendDate') 
      property ('customer.name','customer.name') 

     } 

     ge("invoiceDate", dateFrom) 
     eq("deleteFlag", "N") 
     eq("cif", ciff) 
    }
