在 Typeorm With Repository 方法的 Where 子句中使用 OR 进行 JOINED 查询

Question

我正在尝试使用 Nestjs 中的 connection.getRepository 方法在 TYPEORM 中构建此查询。

                SELECT
                    "car"."RowID"
                FROM
                    "cars"."car" "car"
                    LEFT JOIN "cars"."doors" "doors" ON "car"."doorID" = "doors"."doorID"
                    LEFT JOIN "cars"."wheels" "wheels" ON "car"."wheelID" = "wheels"."wheelID"
                    LEFT JOIN "cars"."engines" "engines" ON "car"."engineID" = 
                    "engines"."engineID"
                WHERE
                        ("car"."Status" = 0 OR "car"."Status" = 2) AND
                        "car"."RetryAttempts" < 5 AND
                        ("doors"."Status" = 3 OR "doors"."Status" = 4) AND
                        ("wheels"."Status" = 3 OR "wheels"."Status" = 4) AND
                        ("engines"."Status" = 3 OR "engines"."Status" = 4)
            )``
    ````
    This is what i came up with but it doesnt work.

this.connection
            .getRepository(CarsEntity)
            .find({
                select: ["rowID"],
                join: {
                    alias: "car",
                    leftJoinAndSelect: {
                        engines: "car.engines",
                        doors: "car.doors",
                        wheels: "car.wheels",
                    },
                },
                where: {
                    retryAttempts: LessThan(5),
                    status:In([
                        0,2]
                    ),
                    engines: {
                        status: In([3,4]
                        )
                    },
                    doors: {
                        status: In([3,4]
                        )
                    },
                    wheels: {
                        status: In([3,4]
                        )
                    }
                }
            });

此查询的 where 子句如下所示

WHERE
    "CarsEntity"."retryAttempts" < @0
    AND "CarsEntity"."status" IN (@1, @2)
    AND "CarsEntity"."engineID" = @3
    AND "CarsEntity"."doorID" = @4
    AND "CarsEntity"."wheelID" = @5

问题是额外的字段来自哪里。是我的查询还是我应该搜索实体？我的身份条件会怎样？

确保版本等于或大于 “typeorm”：“^0.2.37”，

此版本修复了一个错误。以前我在用 “typeorm”：“^0.2.34
