I have the following Pre-request script in Postman that sets environment variables
var current_timestamp = Date.now();
var current_timestamp = current_timestamp ;
var past = current_timestamp - 134;
postman.setEnvironmentVariable("current_timestamp", Number(current_timestamp));
postman.setEnvironmentVariable("past", Number(past));
These variables are referred back in the body of the request:
{
"timestamps": [ "{{current_timestamp}}", "{{past}}"]
}
However, the variables are saved as strings, not as integer. I would like to have in the request body integer values. I tried using Number in the script as suggested in another answer but it does not change a thing.
How can I achieve that?
I had to remove the double quotes: {{current_timestamp}} instead of "{{current_timestamp}}".

I'm trying to make templates for my dahboards, and I have problems when it comes to referring to measuerment names.
My variables:
$space = SHOW MEASUREMENTS
Then I would like a variable that contains only values from a specific $space, which is actually a MEASUREMENT:
$app = SHOW TAG VALUES WITH KEY = "Application" WHERE MEASUREMENT =~ /^$space$/
Here I get a message: Template variables could not be initialized: error parsing query: found MEASUREMENT, expected identifier, string, number, bool at line 1, char 48
In the official example it is like this, though it refers to another tag:
$datacenter = SHOW TAG VALUES WITH KEY = "datacenter"
$host = SHOW TAG VALUES WITH KEY = "hostname" WHERE "datacenter" =~ /^$datacenter$/
I cannot find any info how to refer to MEASUREMENTS which would work. WHERE, WITH, etc.. Maybe is it not possible at all?
I found only this in the official tutorial, but this is for keys, not values.
SHOW TAG KEYS [FROM <measurement_name>]
I actually figured it out:
SHOW TAG VALUES FROM /^$space$/ WITH KEY = "Application"
I have a config file parser written in lua.
I'd like to detect values that are environment variables and change them with os.getenv.
It's probably a bit ambitious because I can have values like
"a string with an embedded ${VARIABLE} in here"
or
"another string with an env $VARIABLE"
And I should probably allow escaping them with double $$ to allow a literal $.
How do I do this?
This is what I have so far, but it isn't right
local envvar = string.match(value, "%$([%w_]+)")
if envvar then
print("Envvar=", envvar)
value = value:gsub("(%$[%w_]+)", os.getenv(envvar))
end
For example, I can't figure out how to use the %b balance option here to properly match { } combinations. And make them optional. How do I make this work robustly?
In fact, I realise it's probably more complicated than this. What if more than one environment variable was specified?
local text = [[
Example: ${LANG}, $TEXTDOMAINDIR, $$10.00, $$LANG, $UNDEFINED
Nested braces: {{${SHELL}}}
]]
text = text:gsub('$%$','\0')
:gsub('${([%w_]+)}', os.getenv)
:gsub('$([%w_]+)', os.getenv)
:gsub('%z','$')
print(text)
--> Example: en_US.UTF-8, /usr/share/locale/, $10.00, $LANG, $UNDEFINED
--> Nested braces: {{/bin/bash}}
In my Grails project I have a Domain Class with a double field as follows:
double totalAmount;
the value of this field are calculated by a sum done after selecting values in a multiple select. the function for sum values is in the controller, as follows:
def sumReceiptItems(){
params.list("receiptItemsSelected").each {i-> println("element "+i)}
def appList = params.list("receiptItemsSelected")
List<ReceiptItem> allSelectedIds = ReceiptItem.findAllByIdInList(params.receiptItemsSelected.split(',')*.toLong())
def totalAmount = allSelectedIds.amount.sum()
println("totalAmount is = "+totalAmount)
render totalAmount as Double
}
the function works well. After function calling, to update the field in GSP page, I use a javascript method as follows:
function updateTotalAmount(name, data, presentNullAsThis){
if(data !=null)
document.getElementById(name).value= data;
else
document.getElementById(name).value=presentNullAsThis;
}
The javascript works and I see the updating of the field at runtime, but the double value is shown with a dot, and not with comma to separate decimal values. Infact, after clicking by save button to save the instance of the domain class, the value is saved without separating decimals, for example:
if the value into the fiels is 10.50 it is stored as 1050
In this discussion how can save a double type correctly in grails? I've read a similar problem, but solution is not good for my issue.
Anybody can help me?
Values with decimal separator depends on the current Locale of the user. Normally you use g.formatNumber in the view to display correctly the value.
You can check this topic on how to discover the decimal separator for a Locale.
To get the user's Locale use:
Locale locale = RequestContextUtils.getLocale(request)
I have solved the problem in this way:
I've updated my Javascript as follows:
function updateTotalAmount(name, data, presentNullAsThis)
{
var data2 = data.toString().replace(/\./g, ',');
if(data2 != null) document.getElementById(name).value= data2;
else document.getElementById(name).value= presentNullAsThis;
}
I've removed "type="number"" in the gsp related field
I have the url parmeters http://www.nositeinparticular.coom/product1?test=brand&old=Superman&new=Batman.
I was wanting to know the proper way to use javascript to do the following;
Look to see if test=brand
If it does replace all the values of old with the value of new, ie replacing the word Superman with Batman.
I have this so far to see if test equals brand:
$(document).ready(function() {
var url = location.pathname;
if (url.indexOf("test=brand")) {
}
How would I go about parsing the values from the url and running the replacment?
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
