Task is simple, but I couldn't find any solution though.
Here is the request I'm sending https://graf-24561-default-rtdb.firebaseio.com/graf-24561-default-rtdb.json
Rules for reading and writing:
{
"rules": {
".read": "now < 1651165200000", // 2022-4-29
".write": "now < 1651165200000", // 2022-4-29
}
}
Data in code:
[
{
"name": "0002 М ( мрамор) 8м пленка с\/м\/20 DEKORON ",
"price": 209.7
},
{
"name": "0007 М ( мрамор) 8м пленка с\/м\/20 DEKORON ",
"price": 209.7
},
{
"name": "0008-2 А (дуб темный) 8м пленка с\/м \/20",
"price": 232.84
},
{
"name": "0008-3 А (темн.махагон) 8м пленка с\/м \/20 ",
"price": 209.7
}
]
The graf-24561-default-rtdb that you see in the root of the JSON in the screenshot is the name of your database, and is not part of the data structure.
So to get the entire database, the URL would be:
https://graf-24561-default-rtdb.firebaseio.com/.json
It may read a bit weird with that .json at the end, but is the correct syntax.

I'm currently working on a Twitter bot that automatically reply messages, I'm doing this by using tweepy (the official python twitter library)
I need to filter messages based on the created time as I don't want to reply same message twice. Now the problem is that the API endpoint returns created_timestamp as string representation of positive integers.
Below is an example of data returned as per the doc
{
"next_cursor": "AB345dkfC",
"events": [
{ "id": "110", "created_timestamp": "1639919665615", ... },
{ "id": "109", "created_timestamp": "1639865141987", ... },
{ "id": "108", "created_timestamp": "1639827437833", ... },
{ "id": "107", "created_timestamp": "1639825389806", ... },
{ "id": "106", "created_timestamp": "1639825389796", ... },
{ "id": "105", "created_timestamp": "1639825389768", ... },
...
]
}
My question is "How do I convert the created_timestamp to a valid date using python" ?.
You might play with timestamps on this resource
And in your case could use methods like:
timestamp = int('timestamp_string')
datetime.fromtimestamp(timestamp, tz=None)
date.fromtimestamp(timestamp)
From the datetime standard library. But integers after the first line are already well comparable if the task is to distinguish differences between the timestamps.
I am using API version 2.0 and unable to fetch the user.fields results. All other parameters seem to be returning results correctly. I'm following this documentation.
url = "https://api.twitter.com/2/tweets/search/all"
query_params = {
"query": "APPL",
"max_results": "10",
"tweet.fields": "created_at,lang,text,author_id",
"user.fields": "name,username,created_at,location",
"expansions": "referenced_tweets.id.author_id",
}
response = requests.request("GET", url, headers=headers, params=query_params).json()
Sample result:
{
'author_id': '1251347502013521925',
'text': 'All conspiracy. But watch for bad news on Apple. Such a vulnerable stocktechnically for the biggest market cap # $2.1T ( Thanks Jay). This is the glue for the bulls. But, they stopped innovating when Steve died, built a fancy office and split the stock. $appl',
'lang': 'en',
'created_at': '2021-06-05T02:33:48.000Z',
'id': '1401004298738311168',
'referenced_tweets': [{
'type': 'retweeted',
'id': '1401004298738311168'
}]
}
As you can see, the following information is not returned: name, username, and location.
Any idea how to retrieve this info?
Your query does actually return the correct data. I tested this myself.
A full example response will be structured like this:
{
"data": [
{
"created_at": "2021-06-05T02:33:48.000Z",
"lang": "en",
"id": "1401004298738311168",
"text": "All conspiracy. But watch for bad news on Apple. Such a vulnerable stocktechnically for the biggest market cap # $2.1T ( Thanks Jay). This is the glue for the bulls. But, they stopped innovating when Steve died, built a fancy office and split the stock. $appl",
"author_id": "1251347502013521925",
"referenced_tweets": [
{
"type": "retweeted",
"id": "1401004298738311168"
}
]
}
],
"includes": {
"users": [
{
"name": "Gary Casper",
"id": "1251347502013521925",
"username": "Hisel1979",
"created_at": "2020-07-11T13:39:58.000Z"
}
]
}
}
The sample result you provided comes from within the data object. However, the expanded object data will be nested in the includes object (in your case name, username, and location). The corresponding user object can be referenced via the author_id field.
I'm trying to create a new device with sensor(s).
This is the payload I'm sending to create the new device:
{"Name":"DeviceABC","HardwareId":"D4xxx425","SpaceId":"xxxx-xxx-xx-xx-xxx","Status":"Provisioned","CreateIoTHubDevice":false,"Properties":[{"Name":"VendorName","Value":"MyVendor"},{"Name":"VendorDeviceId","Value":"D4xxx19425"},{"Name":"VendorDeviceType","Value":"electricity"}],"Sensors":[{"pollRate":0,"id":null,"dataType":"Json","dataUnitType":"KilowattHourEnergy","deviceId":null,"portType":null,"port":"electricity","spaceId":null,"type":"Classic"}]}
In this case I want to use a built in type. KWh
{
"id": 186,
"category": "SensorDataUnitType",
"name": "KilowattHourEnergy",
"disabled": false,
"logicalOrder": 0,
"friendlyName": "kWh"
}
The SensorDataType is :
{
"id": 314,
"spaceId": "xxxx-xx-xxx-xx-xxxx",
"category": "SensorDataType",
"name": "Json",
"disabled": false,
"logicalOrder": 0
}
When I do this for other devices without specifying a dataUnitType in the sensor object, it works fine. But as soon as I include it i get this:
{
"error": {
"code": "400.600.000.000",
"message": "Invalid datatype/dataunittype combination used on sensor."
}}
There seems to be a naming convention between SensorDataType and SensorDataUnitType. The convention is that the SensorDataUnitType needs to end with the full SensorDataType. In your example you have:
"dataType":"Json",
"dataUnitType":"KilowattHourEnergy",
But according to the convention it should be
"dataType":"Json",
"dataUnitType":"KilowattHourEnergyJson",
Of course you can't just change KilowattHourEnergy because it's in a system ontology. So to get it working I had to create KilowattHourEnergyJson as a new type.
I guess the most complete answer would include that in your case the SensorDataType probably shouldn't be JSON but should be Energy.
I use Firebase Database, I have a list of cards, I need to monitor some cards if they are deleted. I tried to do this with ref.observe (.childRemoved), but this is not appropriate for my case, since some data can be deleted by the cardholder, and then this block will fire several times, I need to watch if the entire card was deleted. How can I do that?
My reference
let ref = FIRDatabase.database().reference().child(MainGateways.cards.rawValue).child(card.id)
My cards structure
"cards": {
"-Khv9rUVwErNHBzXcruO": {
"additionalInfo": {
"note": ""
},
"dateProperties": {
"day": "Flex",
"isFlexDate": true,
"isFlexTime": true,

"availableSeats": 1,
"numberOfPeople": 1,
"numberOfPeopleDescription": "1 person"
},
"title": "Genius Lounge and Sake Bar",
"userName": "Tim C.",

},
I also tried to make such a link, but then this block works if any card was removed from the list.
guard let ref = FIRDatabase.database().reference().child(MainGateways.cards.rawValue).child(card.id).parent else { return }
Look into Cloud Functions for Firebase. Using that, you can write JavaScript code that acts in response to database changes at the path you specify. This allows you to write logic independent of the client app to react to changes in the database.
I am trying to get get ownership information against AssetIDs through the Youtube ContentID API.
I can see the data that I need through the API Explorer but cant seem to drill down the data using dot notation.
Here is the output from the API explorer:
{
"kind": "youtubePartner#asset",
"id": "A146063471697194",
"type": "music_video",
"ownership": {
"kind": "youtubePartner#rightsOwnership",
"general": [
{
"ratio": 100,
"owner": "Indmusic",
"type": "exclude"
}
]
},
"ownershipEffective": {
"kind": "youtubePartner#rightsOwnership",
"general": [
{
"ratio": 100,
"owner": "Indmusic",
"type": "exclude"
}
]
}
}
When accessing the "owner" I receive undefined instead of the listed value.
var url2 = _.sprintf('https://www.googleapis.com/youtube/partner/v1/assets/%s?fetchMetadata=effective&fetchOwnership=effective&key=%s',id,API_KEY);
var result2 = JSON.parse(UrlFetchApp.fetch(url2, getUrlFetchOptions()).getContentText());
Logger.log(result2.ownership.general.owner);
returns undefined
I have tried both ownershipEffective and ownership and they are both undefined.
I can log data from result2.ownership.general but nothing below that.
You can tell that general is an array by the [brackets] in:
"general": [
{
"ratio": 100,
"owner": "Indmusic",
"type": "exclude"
}
]
Try:
Logger.log(result2.ownership.general[0].owner);
general, having been declared an array, requires a position [0] even though there is only 1 item in the array.
