Attribute computation error - Customised copy of master
We changed the order of some handlers and hours are now calculated after computed attributes.
Thanks for the response Anton, I just realised I have computed attributes that makes use of hours but it seems like they are not woking anymore after the order was changed.
How will I overcome this?
There was already a thread about it recently. Try searching.
I did a search and also look at the forums often.
Only one I found is https://www.traccar.org/forums/topic/enginehours-not-calculation-after-installing-v61/page/2/
My engine hours are calculating correctly event after the order was changed and I don't have hours or ignition in attributes copying.
I have a computed attribute that calculates average fuel used per km and also per hour that does not seem to work anymore.
hours?10000000-(((totalDistance*0.09)/1000)+((hours)/3600000)):nullApologies if I have missed a thread
Sounds like you have an opposite problem. What version are you using?
Latest master with some customisation.
All worked fine until the order was changed, and I started to get the variable 'hours' is undefined error.
That's the time the computed attribute stopped working as well looking at reports.
That makes sense. The order changed, so your old code doesn't work.
So one cannot reference hours in the computed attributes anymore?
I.E. testing it I create a computed attribute:
Attribute: test
Expression: hours?1:null
Type: number
If I test it within the computed attributes page it return a 1, but returns nothing after linking it to devices or groups and I get variable 'hours' is undefined error.
Yes, but you could calculate the value yourself.
Not working for me.
My devices sends io449 (Teltonika Ignition Hours) in every message.
Testing it in the Computed Attribute it returns 311, but using below it returns 0
Attribute: Hours
Expression: io449?io449:null
Type: number
Am I doing it wrong here?
Does your device actually send it? Check more details screen.
It does,
Looks like you already customized something there.

On a customised copy of latest master I receive the below error almost in every message.
I have no computed attribute with "hours" included linked to any of the devices or groups.
I also checked replays for some of the devices that flagged the warning and "hours" was present at all times.
I also made sure user "admin" have all computed attributes linked to the user account.
Where else can I possibly check for the reason?
If anyone else experience the same issue and can give me some pointers on other areas to check please assist.
