Python aioinflux `serialization.usertype.SchemaError: Can't have more than one timestamp-type attribute`, how to avoid it?

Question

我有这个 dataclass 和这样的 lineprotocol 架构：

from datetime import date, datetime
from aioinflux import lineprotocol, TIMEDT, TAG, FLOAT, MEASUREMENT, STR, INT
from dataclasses import dataclass
from shared import DEBUG_TABLE_NAME


@lineprotocol(
    schema=dict(
        timestamp=TIMEDT,
        measurement=MEASUREMENT,
        target_id=INT,
        type=TAG,
        weight=FLOAT,
        confidence=FLOAT,
        statement=TAG,
        now_time=TIMEDT,
        height=INT,
        dt_time=TIMEDT,
        success=TAG,
    )
)
@dataclass
class DataPoint:
    timestamp: datetime
    target_id: int
    type: str
    weight: float
    confidence: float
    statement: str
    now_time: datetime
    height: int
    dt_time: datetime
    success: str
    measurement: str = DEBUG_TABLE_NAME

但是在尝试运行代码时出现此错误： aioinflux.serialization.usertype.SchemaError: Can't have more than one timestamp-type attribute [~TIMEINT, ~TIMEDT, ~TIMESTR]

我还需要一些其他属性，例如 now_time 和 dt_time，时间格式要短一些。但这似乎引发了 aioinflux 的错误。如何避免这种情况？

Answer 1

字段的有效值类型仅为：Float、Integer、UInteger、String、Boolean (Reference)

您可以做的是将日期存储为整数（时间戳）或字符串（RFC3339 格式）。然后，如果需要，您可以在 Flux 查询中将其投回，使用：

toTime() 方便转换 _value
time() 转换单个值（例如，在 map() 内）
