小编W. *_*ens的帖子

我目前正在运行一个查询，该查询运行一个 sum 函数并将这个数字除以。目前我得到的值是 0.0904246741698848 和 1.6419814808335567。我希望将这些小数修剪为小数点后 2 个空格。他们的架构是一个浮点数。这是我的代码。谢谢您的帮助。

#standardSQL
SELECT
  Serial,
  MAX(createdAt) AS Latest_Use,
  SUM(ConnectionTime/3600) as Total_Hours,
  COUNT(DISTINCT DeviceID) AS Devices_Connected
FROM `dataworks-356fa.FirebaseArchive.Firebase_ConnectionInfo`
WHERE PeripheralType = 1 or PeripheralType = 2 or PeripheralType = 12
GROUP BY Serial
ORDER BY Latest_Use DESC

我有一个Python脚本,它从firebase下载数据,操作它然后将其转储到JSON文件中.我可以通过命令行将其上传到BigQuery,但现在我想将一些代码放入Python脚本中以便将其全部完成.

这是我到目前为止的代码.

import json
from firebase import firebase

firebase = firebase.FirebaseApplication('<redacted>')
result = firebase.get('/connection_info', None)
id_keys = map(str, result.keys())

#with open('result.json', 'r') as w:
 # connection = json.load(w)

with open("w.json", "w") as outfile:
  for id in id_keys:
    json.dump(result[id], outfile, indent=None)
    outfile.write("\n")

这是我在BigQuery中运行的查询,我想在我的python脚本中运行.我将如何更改此/我必须添加什么才能在Python中运行它.

#standardSQL
SELECT
  Serial,
  MAX(createdAt) AS Latest_Use,
  SUM(ConnectionTime/3600) as Total_Hours,
  COUNT(DISTINCT DeviceID) AS Devices_Connected
FROM `dataworks-356fa.FirebaseArchive.testf`
WHERE Model = "BlueBox-pH"
GROUP BY Serial
ORDER BY Serial
LIMIT 1000;

从我一直在研究的是,我不能将这个查询保存为使用Python的永久表.真的吗？如果是真的,是否仍然可以导出临时表？

我正在尝试将 JSON 上传到谷歌云存储。我可以手动完成，所以我知道它可以工作，但现在想编写一个可以自动完成的 python 脚本。

import boto
import gcs_oauth2_boto_plugin
import os
import shutil
import StringIO
import tempfile
import time

from google.cloud import storage
from google.cloud.storage import blob

client = storage.Client(project='dataworks-356fa')
bucket = client.get_bucket('dataworks-356fa-backups')
blob = bucket.blob('t.json')
with open('t.json', 'rb') as f:
  blob.upload_from_file('f')

是我到目前为止的代码，这是我得到的错误。

Traceback (most recent call last):
  File "uploadcloud.py", line 16, in <module>
    blob.upload_from_file('f')
  File "/Library/Python/2.7/site-packages/google/cloud/storage/blob.py", line 891, in upload_from_file

目前我有一个 Python 脚本向 slack 发送消息。我想添加额外的链接，但不知道如何添加。这是我当前的代码。

def post_slack():
    """Post slack message."""
    try:
        token = 'xoxp-67503713541-67496795984-216701772021-c23bdfbe9635f1f63a4c802697147dfc'
        slack = Slacker(token)

        obj = slack.chat.post_message(
            channel='#dataworksapp',
            as_user= 'false',
            username = 'DataWorksBot',
            attachments=[
        {
            "color": "033E96",
            "title": "Pressure Transducer Weekly Information",
            "title_link": "https://console.cloud.google.com/storage/browser/firebase_results/?project=dataworks-356fa",
            "author_name": "Master Table",
            "author_link": "https://bigquery.cloud.google.com/table/dataworks-356fa:FirebaseArchive.PT_MasterTable?tab=preview",
            "text": "https://bigquery.cloud.google.com/table/dataworks-356fa:FirebaseArchive.PT_MasterTable?tab=preview",
            "fields": [
                {
                    "title": "Amount Used:",
                    "value": "countPTserial1",
                    "short": 'true'
                },{
                    "title": "Distinct Device ID's:",
                    "value": "countPTid1",
                    "short": 'true'
                },{
                    "title": "Total Connection Time (hr):",
                    "value": "sumPTct2",
                    "short": 'true'
                }
            ]

我无法找到任何其他类似于“author_link”的字段类别，我可以将其设置为等于链接。我可以设置"text"等于链接，但如果我这样做，我更愿意将链接作为单个单词而不是在消息中发送整个丑陋的链接。

另外，我无法将链接设置为等于变量，然后设置"text" …
