错误：错误：“NOT”类型或附近的语法错误

Question

您好，我正在为我选择 Postgres 的数据库创建一个带有 NestJs 的应用程序，orm 是 TypeOrm，我正在创建我的迁移，迁移是一个文件，并且我已经配置了 package.json ，但是当我使用yarn typeorm migration:run 运行时，返回此错误：

query failed: CREATE TABLE "users" ("id" NOT NULL, "name" varchar NOT NULL, "email" varchar NOT NULL, "password" varchar NOT NULL, "biography" varchar NOT NULL, "links" varchar NOT NULL, "posts" int NOT NULL, "created_at" date NOT NULL DEFAULT now(), CONSTRAINT "UQ_97672ac88f789774dd47f7c8be3" UNIQUE ("email"), CONSTRAINT "posts" FOREIGN KEY ("posts") REFERENCES "posts" ("id") ON DELETE CASCADE ON UPDATE CASCADE, CONSTRAINT "PK_a3ffb1c0c8416b9fc6f907b7433" PRIMARY KEY ("id"))

我的迁移代码太大所以放在这里：https://pastebin.com/Ww2d0F16

这是什么错误？我正在搜索，但没有找到任何有此错误的软件，您能帮帮我吗？

Answer 1

type: 'id' 在 PosgresSQL 上不存在！

你可以试试这个=>

export class post1617813884949 implements MigrationInterface {
  public async up(queryRunner: QueryRunner): Promise<void> {
    await queryRunner.createTable(
      new Table({
        name: 'users',
        columns: [
          {
            name: 'id',
            type: 'number', // Number if your primary key is number else varchar if your primary key is uuid
            isPrimary: true,
            isGenerated: true,
            generationStrategy: 'increment',
          },
          {
            name: 'name',
            type: 'varchar',
          },
          {
            name: 'email',
            type: 'varchar',
            isUnique: true,
          },
          {
            name: 'password',
            type: 'varchar',
          },
          {
            name: 'biography',
            type: 'varchar',
          },
          {
            name: 'links',
            type: 'varchar',
          },
          {
            name: 'posts',
            type: 'int',
          },
          {
            name: 'created_at',
            type: 'date',
            default: 'now()',
          },
        ],
        foreignKeys: [
          {
            name: 'posts',
            columnNames: ['posts'],
            referencedTableName: 'posts',
            referencedColumnNames: ['id'],
            onUpdate: 'CASCADE',
            onDelete: 'CASCADE',
          },
        ],
      }),
    );
    ...other_table
}
