问题描述

在Grails领域类中,如何为String字段设置约束,使其MySQL列类型为TEXT或LONGTEXT?



到目前为止我最好的方法是设置约束的大小:

pre $ myTextField(size:0..65535)

导致TEXT

  myTextField(size :0..2147483646)

结果为LONGTEXT(2147483646 = 2 ^ 32/2 - 1 - 1 )



是否有更简洁的方式来指定尺寸?基本上我需要TEXT或LONGTEXT的全部范围,而不必硬编码一堆尺寸值。

您可以声明您的Domain类的映射关闭:

 静态映射= {
myTextField类型:'text'
}

In a Grails domain class, how do I set the constraint for a String field so that its MySQL column type is TEXT or LONGTEXT?

So far my best approach is to set the constraint's size:

myTextField(size:0..65535)

which results in TEXT

myTextField(size:0..2147483646)

results in LONGTEXT (2147483646 = 2^32 / 2 - 1 - 1)

Is there a cleaner way to specify the size? Basically I want the full range of TEXT or LONGTEXT without having to hardcode a bunch of size values.

解决方案

You can declare that in the mapping closure of your Domain class:

static mapping = {
   myTextField type: 'text'
}

(See ORM DSL Documentation)
