I am trying to create a script using mongo shell in Robo3T, where I can get returned all the latest dates of users that have submitted to userhistories. Although for some reason this script wont work. I am trying to compare 2 rows and then print the date if the ID is the same.
function lastDate(userID) {
print(db.userhistories.find({"user": userID}).sort({date:1}).limit(1));
}
lastDate(db.users.find().forEach(function(val){ val._id.toString()}));
What is wrong with this script? Or is there a better way to fix this issue??

I am setting a Variable in Grafana.
I want to create a Query, that only returns a subset of the labels with value app the ones I want to return are those ending in dev
My Query so far, returns all of the labels with value app successfully. However, I have been unable to successfully filter the values so that only a-dev b-dev and c-dev are returned.
How do I successfully apply regex (or alternative) to this query so that I can see the desired values?
Any help on this would be greatly appreciated!
I eventually figured out what I needed to do. Originally I was trying to use | to run regex on the results from label_values.
However, this format worked:
label_values({app=~".*-dev$"}, app)
and returned only a-dev b-dev c-dev as expected.
Currently, I was working on a Unity project and using Firestone as my database.
now i facing a problem is when i create a document in firestone i want to add the time of creation also.
i was using the code
db.Collection("Challenges").Document(addedDocRef.Id).UpdateAsync("TimeCreated", Firebase.Firestore.FieldValue.ServerTimestamp);
but it always update the same time in firestone.
every document get same timestemp, can anyone teach me how to solve this issue?
The FieldValue properties are sentinel values in this case to be understood as dummy values that are supposed to be filled in by "someone".
I don't know how Firebase works exactly and who is supposed to fill this in but what you get basically equals DateTime.UnixEpoch the default uninitialized system time (+ 7:30 timeszone shift). It might have to be configured accordingly somewhere before it works correctly.
You could instead simply pass in your own timestamp using e.g. DateTime.Now
i´ve a quick question regarding a zabbix trigger expression. Our script finds out the certification lifetime while returning a number into a file. I already created some triggers for specific time spans (like 10 days or 44 days).
For example:
{Certificate Lifetime:vfs.file.contents[C:\Zabbix_scripts\cert.txt].prev()}<=30 and {Certificate Lifetime:vfs.file.contents[C:\Zabbix_scripts\cert.txt].prev()}>10
I now want to have a trigger which will cause an "Disaster" when the value in the .txt file is unavailable, like the txt file is empty.
I´ve tried
{Certificate Lifetime:vfs.file.contents[C:\Zabbix_scripts\cert.txt].prev()}=0
But this was not the right sulution. Any ideas?
Moreover we have some machines which are equal to others but doesn´t show any value. Any ideas at this point?

You should be able to detect empty item value with something like this:
strlen()=0
$shop=DB::table('shops')
->leftJoin('orderbookings',function($join)
{
$join->on('shops.id','=','orderbookings.shop_id');
$join->on('orderbookings.created_at','>=',DB::raw(date("Y-m-d",strtotime("now"))));
})
->select('shops.*')
->selectRaw('COUNT(orderbookings.id) as totalorder, SUM(orderbookings.grand_total) as gtotal')
->orderBy('shops.shop_name', 'asc')
->groupby('shops.id')
->paginate(10);
Above code working fine(But not giving total order and amount correct) and also gives result almost close to what I want,
But I am not able to give date format (Y-m-d H:i:s), it shows syntax error. I am using Laravel 5.2 version
Note: I want to give time as well with date to rectify result,
On giving [example: 2017-03-08 11:15:00] shows syntax error
working query in mysql
SELECT COUNT(orderbookings.id), SUM(orderbookings.grand_total), shops.shop_name FROMshopsLEFT JOIN orderbookings on orderbookings.shop_id = shops.id and orderbookings.created_at BETWEEN "2015-10-22 17:02:02" AND "2017-03-07 17:02:02" GROUP BY shops.id
But not able to to convert in eloquent
You should be able to do the following:
$join->on('orderbookings.created_at', '>=', date("Y-m-d"));
You don't need to use DB::raw, and leaving the second parameter null for date, assumes "now".
If this doesn't solve your issue, please post the exact error you're seeing.
I am trying to update a Quickbase record via my Perl script. I am following the Perl API documentation: http://metacpan.org/pod/HTTP::QuickBase
The method used for editing a record is "EditRecord". As per this method, you cannot edit built-in fields which is true.
and I know that I am not modifying built-in field but an user-created field.
e.g. I want to modify the field called "OS" to "Windows"
So per the Perl modules CPAN documentation mentioned above, I do this:
my %new_record=$qb_obj->GetRecord($database_id, $record_id);
$new_record{"OS"}="Windows";
$qb_obj->EditRecord($database_id, $record_id, %new_record);
But I get following error:
The field named "Date Created" with field id 1 cannot be modified
Which basically means that I ma trying to modify the field "Date Created" with Field ID "1". However, I am not doing that. It might be pulling that parameter some how. THe perl as well as the Quickbase documentation is not helping much.
Here is the Quickbase API documentation: http://www.quickbase.com/api-guide/edit_record.html#Overview
Can someone help me on this.
thanks.
Since you already know the id of the record, you don't need to read the record before modifying it. You should be able to just remove your first line, create the %new_record without reading it from QB, then your 2nd and 3rd lines should work fine.
The alternative is to remove the built-in QB fields from %new_record before doing the EditRecord.
