Parsing date time in D3.js - parsing

I'm trying to parse the date time value from .csv file in D3.js, but for some reason I keep getting null. Here's what I have,
.csv data:
"","date","count"
"1","2011-11-15 02:00:01",1
"2","2011-11-15 02:00:02",2
"3","2011-11-15 02:00:03",1
"4","2011-11-15 02:00:04",1
"5","2011-11-15 02:00:05",1
"6","2011-11-15 02:00:07",1
var parseDate = d3.time.format("%I:%M %p").parse;
When I do console.log(parseDate(d.date)), I get null. I also tried console.log(parseDate(d.date.toString())), but I still get null. Why is it not parsing?

thingsboard rulechain - filter script node to check if metadata timestamp is greater than server timestamp

I have created an asset variable with a timestamp attribute (dateTo) and would like to compare this to the current server time.
Ho do I get the server/system time of the Thingsboard. TBEL documentation states that "we have added Date class that you are able to use without the package name" so I should be able to get the server time with:
Date
Testing in the Test Filter Function doesn't error while using:
return Date > metadata.dateTo;
But does not assess correctly (changing the value around generates a False result either way).
Each metadata field has a string type, instead of integer as expected. So before comparison you have to convert metadata.dateTo to integer:
return Date.now() > +metadata.dateTo;

Using API in GoogleSheet

I want to import in google sheet data from https://www.coinspeaker.com/ieo/feed/
function callCoinSpeaker() {
var response = UrlFetchApp.fetch("https://www.coinspeaker.com/ieo/feed/");
Logger.log(response.getContentText());
var fact = response.getContentText();
var sheet = SpreadsheetApp.getActiveSheet();
sheet.getRange(1,1).setValue([fact]);
}
The script works fine, but I don't know how to format the output that is all in a single cell (A1).
I would like to create a code that automatically format the output splitting into column and row. Any example of formatting output from API request?Thanks ALL!
What I think about your issue in when you're making a GET request to your link, the response is back as a string.
To be able to use the data, you should parse your response with the method JSON.parse(fact)
Use Logger.Log(JSON.parse(fact)) to see what is happening.

Deserialize joda time from string in grails?

I had a LocalTime field (using Joda Time) in Grails domain class.
Class WorkDone{
LocalTime duration
}
Now I have altered this field to String (with Text constraint) so that it can support duration larger than 24 hrs.
String duration
The problem is there is already some data in database. And I want to sanitize that data through database migrations in Grails. I am using Postgres which saves LocalTime as Bytea (binary data).
When I call WorkDone.duration it returns me a String of the form:
\xaced0005737200176f72672e6a6f64612e74696d652e4c6f63616c54696d65fffff44abbf29def0200024a000c694c6f63616c4d696c6c69734c000b694368726f6e6f6c6f677974001a4c6f72672f6a6f64612f74696d652f4368726f6e6f6c6f67793b78700000000000000000737200276f72672e6a6f64612e74696d652e6368726f6e6f2e49534f4368726f6e6f6c6f67792453747562a9c811667137502703000078707372001f6f72672e6a6f64612e74696d652e4461746554696d655a6f6e652453747562a62f019a7c321ae30300007870770500035554437878
How can I extract time from this string?
Your data is scaped in bytea Hex format, (starts with \x) take a look at PostgreSQL docs
http://www.postgresql.org/docs/current/static/datatype-binary.html
You have to unescape it before read as ObjectInputStream ang get the LocalTime object, unescape it and then try again as Raphael suggest.
You should have done a data-migration before changing your Data-type to String.
Here is what you should do.
1. Change the Data-type of the field back to LocalTime.
2. Create a new field with String Date.
3. Write a script that would get all date in LocalTime and convert it to String and save it in new field.
4. Once you have your data migrated, delete the old field and then rename your new field to duration.
I ended up doing the following -
grailsChange{
change{
sql.eachRow("Select id,duration from work_done"){
def wdId = it.id
def durationObj = (LocalTime)(new ObjectInputStream(new ByteArrayInputStream(it.duration))).readObject()
durationObj = durationObj.toString().substring(0,8)
WorkDone.executeUpdate("update WorkDone wd set wd.duration=:newDuration" +
"where wd.id=:wdId",
[newDuration:durationObj ,wdId:wdId ])
}
}

How to use Slickgrid Formatters with MVC

I am working on a first Slickgrid MVC application where the column definition and format is to be stored in a database. I can retrieve the list of columns quite happily and populate them until I ran into the issue with formatting of dates. No problem - for each date (or time) column I can store a formatter name in the database so this can be retrieved as well. I'm using the following code which works ok:
CLOP_ViewColumnsDataContext columnDB = new CLOP_ViewColumnsDataContext();
var results = from u in columnDB.CLOP_VIEW_COLUMNs
select u;
List<dynColumns> newColumns = new List<dynColumns>();
foreach(CLOP_VIEW_COLUMN column in results)
{
newColumns.Add(new dynColumns
{
id = column.COLUMN_NUMBER.ToString(),
name = column.HEADING.Trim(),
field = column.VIEW_FIELD.Trim(),
width = column.WIDTH,
formatter = column.FORMATTER.Trim()
});
}
var gridColumns = new JavaScriptSerializer().Serialize(newColumns);
This is all fine apart from the fomatter. An example of the variable gridColumns is:
[{"id":"1","name":"Date","field":"SCHEDULED_DATE","width":100,"formatter":"Slick.Formatters.Date"},{"id":"2","name":"Carrier","field":"CARRIER","width":50,"formatter":null}]
Which doesn't look too bad however the application the fails with the error Microsoft JScript runtime error: Function expected in the slick.grid.js script
Any help much appreciated - even if there is a better way of doing this!
You are assigning a string to the formatter property, wich is expected to be function.
Try:
window["Slick"]["Formatters"]["Date"];
But i really think you should reconsider doing it this way and instead store your values in the db and define your columns through code.
It will be easier to maintain and is less error prone.
What if you decide to use custom editors and formatters, which you later rename?
Then your code will break or you'll have to rename all entries in the db as well as in code.

Delphi & Absolute database : Delete Query

Why is it that my query does not work ?
Form1.ABSQuery1.Close;
Form1.ABSQuery1.SQL.Clear;
Form1.ABSQuery1.SQL.Text:='DELETE FROM LOG WHERE status = ''YES'' and DATE BETWEEN :d1 and :d2';
Form1.ABSQuery1.Params.ParamByName('d1').Value :=cxDateEdit1.Date;
Form1.ABSQuery1.Params.ParamByName('d2').Value :=cxDateEdit2.Date;
Form1.ABSQuery1.ExecSQL;
Form1.ABSTable1.Refresh;
I get this error :
You should be using AsDateTime in your Params setting code.
Form1.ABSQuery1.SQL.Text:='DELETE FROM LOG WHERE status = ''YES'' and DATE BETWEEN :d1 and :d2';
Form1.ABSQuery1.Params.ParamByName('d1').AsDateTime :=cxDateEdit1.Date;
Form1.ABSQuery1.Params.ParamByName('d2').AsDateTime :=cxDateEdit2.Date;
Form1.ABSQuery1.ExecSQL;
Using Value converts the cxDateEdit1.Date to a generic string format for assignment, and that doesn't properly convert it to the YYYY-MM-DD format that most databases (including ABS) expect. Properly using AsDateTime allows the database driver/component to convert to the specific date format the DBMS uses.
Also, is your database field really named DATE? Date is usually a reserved word or function name in most DBMS, and if it is it usually needs to be quoted.
Form1.ABSQuery1.Params.ParamByName('d1').DataType := ftDateTime;
Form1.ABSQuery1.Params.ParamByName('d1').Value :=cxDateEdit1.Date;
You must explicitly specify the data type of the parameter to it had no such problem, and then convert to a string does not need to
