How do I query data between two date and time from django model.
I am using below code but it is not working. Here In Db for every second data is populated and from browser every second or minute or hours or current date or week, a Ajax is request sent.
However currently I am not filtering the data based upon they date+ time because of this server takes time to respond. Please guide me how do I query data model between date+time
tempresult=Realtimekwhrtu1.objects.filter(datetime_published__range=(
datetime.datetime.combine('2008-03-27',datetime.time.min),
datetime.datetime.combine('2008-03-27',datetime.time.max)))
JSON example:
{

I am running into an issue creating recurring events in the past using Graph API. When I POST this data to /me/calendars/[calendarId]/events I get an ErrorPropertyValidationFailure error:
{
"isAllDay": true,
"start": {
"timeZone": "America/New_York",
"dateTime": "2000-09-02"
},
"end": {
"timeZone": "America/New_York",
"dateTime": "2000-09-03"
},
"subject": "Jimmy's birthday",
"body": { "contentType": "text", "content": "" },
"isCancelled": false,
"recurrence": {
"pattern": {
"type": "absoluteYearly",
"interval": 1,
"dayOfMonth": 2,
"month": 9
},
"range": { "startDate": "2000-09-02", "type": "noEnd" }
},
"showAs": "free",
"type": "seriesMaster"
}
All of the data seems valid to me, and indeed just changing the start and end dateTime values and the recurrence range's startDate to be in 2019 instead of 2000, and it seems to work.
But here's where it gets weird: keep those values in 2000, and change the dayOfMonth in the recurrence pattern to an incorrect value, like 5. Then when submitting to the API, it works! The recurrence will instead appear to begin on Sep 5 of 2000 and there is nothing on Sep 2 (also, the event seems to run "Tue 9/5/2000, 11:00 PM to Wed 9/6/2000, 11:00 PM" on the calendar, which is strange, since it also appears as an all-day event).
So my question is: is this a bug? Or what the heck's happening? It looks like correct data is getting a validation error, but incorrect data creates an event.
Updating to add the error body:
{
"error": {
"code": "ErrorPropertyValidationFailure",
"message": "At least one property failed validation.",
"innerError": {
"date": "2020-10-15T22:48:50",
"request-id": "c08b1d73-5b6d-46ac-8751-d1f17310f652",
"client-request-id": "c08b1d73-5b6d-46ac-8751-d1f17310f652"
}
}
}
I'm trying to create a table that shows the top 5 nested objects in an array.
My documents look something like this:
{
"_id": 1,
"workers": [
{
"worker_id": 1,
"units": [
{
"unit_id": 1,
"time": 100
},
{
"unit_id": 2,
"time": 200
},
{
"unit_id": 3,
"time": 300
},
{
"unit_id": 4,
"time": 400
}
]
},
{
"worker_id": 2,
"units": [
{
"unit_id": 11,
"time": 1000
},
{
"unit_id": 12,
"time": 200
},
{
"unit_id": 13,
"time": 300
},
{
"unit_id": 14,
"time": 350
}
]
}
]
}
I would like to have two columns in the table. One column with the _id of the document and the other with the unit_id. In the second column should be only the top five units that have the highest time.
Is this possible with Grafana?
For computing the top 5 entries from the nested Object, you can use simple-json-datasource plugin. You can create a simple Webapp which does the JSON Parsing logic and return the data in the format you want
I'm trying to use YQL Console to get currency rates, the YQL statement is
select * from yahoo.finance.xchange where pair in ("EURUSD","GBPUSD")
the console results give me
{
"query": {
"count": 2,
"created": "2017-10-26T02:42:44Z",
"lang": "en-US",
"results": {
"rate": [
{
"id": "EURUSD",
"Name": "EUR/USD",
"Rate": "1.1829",
"Date": "10/26/2017",
"Time": "3:42am",
"Ask": "1.1829",
"Bid": "1.1829"
},
{
"id": "GBPUSD",
"Name": "GBP/USD",
"Rate": "1.3269",
"Date": "10/26/2017",
"Time": "3:42am",
"Ask": "1.3269",
"Bid": "1.3269"
}
]
}
}
}
but the rest query gives me error
{"error":{"lang":"en-US","diagnostics":{"cache":{"execution-start-time":"0","execution-stop-time":"0","execution-time":"0","method":"GET","type":"MEMCACHED","content":"ENV.queryyahooapiscomproductionsg3.store://datatables.org/alltableswithkeys.15a841ff462a38eb6175e73b4dc747ef"},"env":"Failed to read from storage: store://datatables.org/alltableswithkeys: Invalid store url: store://datatables.org/alltableswithkeys","warning":"Invalid environment specified: store://datatables.org/alltableswithkeys"},"description":"No definition found for Table yahoo.finance.xchange"}}
The yahoo.finance.xchange is a community table. In the YQL console there should be a checkbox saying Show Community Tables select that and you should have access to it. The REST call here works. Let me know if you have any questions.
I am using a d3.js time.scale like this:
var xScale = d3.time.scale()
.domain(d3.extent(data, function(d) { return d.date; }))
.range([0, chartWidth]);
The data is like this:
var testData = [
{
"date": "2015-04-01T00:00:00.000Z",
"value": 200.00
},
{
"date": "2015-05-01T00:00:00.000Z",
"value": 2000.00
},
{
"date": "2015-06-01T00:00:00.000Z",
"value": 4000.01
},
{
"date": "2015-07-01T00:00:00.000Z",
"value": 1000.00
},
{
"date": "2015-08-01T00:00:00.000Z",
"value": 750.00
},
{
"date": "2015-09-01T00:00:00.000Z",
"value": 1568.00
},
{
"date": "2015-10-01T00:00:00.000Z",
"value": 3789.00
},
{
"date": "2015-11-01T00:00:00.000Z",
"value": 5678.00
},
{
"date": "2015-12-01T00:00:00.000Z",
"value": 4898.00
},
{
"date": "2016-01-01T00:00:00.000Z",
"value": 9002.00
},
{
"date": "2016-02-01T00:00:00.000Z",
"value": 3320.00
},
{
"date": "2016-03-01T00:00:00.000Z",
"value": 12000.00
}
];
But the ticks and the ordering are not as I would expect:
I would expect the ticks to be ordered from april 2015 to march 2016 and I do not understand where the 2016 tick is coming from.
How can I order the ticks as I would expect and also where is the 2016 tick coming from?
Here is a jsbin that shows the problem
If you want the ticks to show the month name and the year, add this to the axis:
.tickFormat(d3.time.format("%B %Y"));
Alternatively, you can display the abbreviated month name:
.tickFormat(d3.time.format("%b %Y"));
Here is the updated jsbin: http://jsbin.com/wikafuluqu/1/edit?js,output
PS: To show the first tick, add nice() to the scale. This is the jsbin with nice():

Basically, no bubbles are displayed because the group which I use for the chart is empty.
what my data structure looks like :
[{
"site": "Site",
"service": "Long Term Care",
"value": 67.52,
"quarter": "Q1",
"date": "2015-02-13T22:00:00.000Z",
"groupId": 1
}, {
"site": "Site",
"service": "Long Term Care",
"value": 67.19,
"quarter": "Q2",
"date": "2015-05-15T21:00:00.000Z",
"groupId": 1
}, {
"site": "Site",
"service": "Long Term Care",
"value": 66.87,
"quarter": "Q3",
"date": "2015-08-14T21:00:00.000Z",
"groupId": 1
}, {
"site": "Site",

"value": 66.57,
"quarter": "Q4",
"date": "2015-11-14T22:00:00.000Z",
"groupId": 1
}, {
"site": "Site",
"service": "Assisted Living",
"value": 75.36,
"quarter": "Q1",
"date": "2015-02-13T22:00:00.000Z",

}, {
"site": "Site",

I want to display a bubble for each row in my data source. I created a dimension based on the quarters (I've also tried using the date field but with the same result) and a group based on the value field (each value is a unique float number). But when printing the resulting group in the console, it returns an empty array. Now I'm not sure if it is even possible to do what I have in mind.
Rest of the code:
ndx = crossfilter(myData);
dateDimension = ndx.dimension(dc.pluck('quarter'));
print_filter(dateDimension);
valueGroup = dateDimension.group(dc.pluck('value'));
print_filter(valueGroup);
minValue = dateDimension.bottom(1)[0].value;
maxValue = dateDimension.top(1)[0].value;
testChart = dc.bubbleChart("#test-chart");
testChart.width(850).height(350).dimension(dateDimension).group(valueGroup)
.renderLabel(false)
.maxBubbleRelativeSize(0.3)
.radiusValueAccessor(function (p) {
return p.value.value;
})
.x(d3.scale.ordinal().domain(["Q1", "Q2", "Q3", "Q4"]))
.xUnits(dc.units.ordinal)
.y(d3.scale.linear().domain([0, maxValue + 10])).yAxisLabel("", 20);
dc.renderAll();
Here is the JsFiddle
Here is a picture of what I expected the chart be like.
Lots of issues here, but the main thing is getting your groups properly defined for the visualization you want to do. Here's an update to your JSFiddle that may get you started: https://jsfiddle.net/yewk7c0r/15/
Basic idea for groups is to define your dimension at the level of granularity you need for your visualization and then define your group using reduceSum (or a custom grouping if you want to do average or something like that):
ndx = crossfilter(myData);
dateDimension = ndx.dimension(function(d) {
return [d.quarter, d.service];
});
valueGroup = dateDimension.group().reduceSum(dc.pluck('value'));
