postgresql – Knex在Postgres中创建POINT数据类型

我正在尝试使用POINT数据类型&创建一个模式. knex似乎没有在DB中创建它.然而,它正在创建所有其他领域.

这是我的迁移文件的样子：

exports.up = (knex,Promise) => {
  return Promise.all([
    knex.schema.createTableIfNotExists('users',(table) => {
      table.uuid('id').primary()
      table.string('username',35)
      table.text('pword').notNullable()
      table.string('first_name',55)
      table.string('last_name',55)
      knex.schema.raw('coordinates POINT DEFAULT POINT (37.3875,-122.0575)')
      table.timestamp('date_created').defaultTo(knex.fn.now())
    })
  ])
}

exports.down = (knex,Promise) => {
  return Promise.all([
    knex.schema.dropTableIfExists('users')
  ])
}

这是失败的代码行：

knex.schema.raw('coordinates POINT DEFAULT POINT (37.3875,-122.0575)')

我也尝试删除schema属性：

knex.raw('coordinates POINT DEFAULT POINT (37.3875,-122.0575)')

没有打印出错误,它似乎无声地失败.

编辑1：

我用以下方法打印出来：knex.schema.raw(‘坐标POINT DEFAULT POINT(37.3875,-122.0575)’).然后(data => console.log(data)).catch(error => console.log(错误))

{ error: coordinates POINT DEFAULT POINT (37.3875,-122.0575) - syntax error at or near "coordinates"

解决方法

试试这个：

table.specificType(‘coordinates’,’POINT’).defaultTo(knex.raw(‘POINT(37.3875,-122.0575)’))

对于Knex未涵盖的SQL类型,您始终可以使用以下格式：

table.specificType(‘column_name’,’TYPE’)
