船帆-船尾-无法启航

Question

问题:无法提升sails项目(最初为mysql编写，将适配器和设置更改为postgres)

错误：

适配器响应：

我尝试过更改数据存储设置，尝试本地主机和远程部署，用户名和密码，更改角色，数据库权限。但似乎什么都解决不了这个问题。

我是不是遗漏了什么？

   adapter: 'sails-postgresql',
   url: 'postgresql://postgres:postgres@localhost:5432/postgres',

一种型号：

module.exports = {
    tableName: 'roles',
    attributes: {
        name: {
            type: "string",
            required: true,
            columnType: "varchar(255) COLLATE utf8_unicode_ci NOT NULL"
        },
        company_id: {
            type: "number",
            required: true,
            columnType: "int(11) NOT NULL"
        },
        mobile_user: {
            type: "number",
            required: false,
            defaultsTo: 0,
            columnType: "tinyint(1) NOT NULL DEFAULT '0'"
        },
        enforcement: {
            type: "number",
            required: false,
            defaultsTo: 0,
            columnType: "tinyint(1) NOT NULL DEFAULT '0'"
        },
    }
};

我正在将数据库从mysql迁移到postgre。有谁面临同样的问题吗？

Answer 1

在尝试了更多的设置和更改之后。我发现这个问题是由模型引起的，即通过将模型的columnType中提到的所有数据类型和条件从MySQL更改为PostgresSQL，就像一种魅力。

示例: tinyint(1) -> smallint，删除排序条件等
