Workout display error when speeds are zero

[dkm]

I've been importing ~600+ workouts, and apart from little changes, it nearly worked correctly.

But I'm unable to display some of these and am left with a nearly empty page:

The console gives:

It looks like the distance is null at some point, but I can see it is 0.001. Is it possible the 0.001, while being a valid float, is too low and got the routines that convert it to produce invalid result? I'm using 0.001 for importing "workouts" that have no GPX files and for which I don't have all the data (except for the duration) as 0 is not valid.

I'm up to date wrt the dev branch (e3bb7e5).

The only local change (used to accommodate larger notes than 500 chars) I have is:

I've tried to use the debugger but maybe you'll have a better idea of what is going on as web dev is not really my domain...

Hi,

Thanks for the bug report.
I'll take a look at the Distance component to better handle this error first (and try to reproduce the same error).

[dkm]

Ok thanks for your help. Let me know if I can help. I can probably provide you with the data for the problematic workout.

[SamR1]

yes, can you provide an example that generates this error? Thanks in advance.

I think the error is due to speeds (Distance component is also used to display speed, I should maybe rename it).
In console log, aveSpeed and maxSpeed are null.

[dkm]

Here are the various fields for a GPX less workout (the "notes" field is probably not important)

--sport Paragliding
--ascent 0.0 
--descent 0.0 
--duration 1200 
--distance 0.001
--date "2020-08-06 00:00"
--title "Saint Hilaire - Déco Sud - Vol local"
--notes "some very long text that won't fit in VARCHAR(250) but it's probably not the root cause anyway"

[SamR1]

thanks!

I reproduce the same error when adding a workout without gpx file and with the same values.
After a fix on API side, it returns 0.00 km/h for average and max speeds (the calculated value is 0.003 km/h, but in database only 2 digits are stored):

fittrackee=> SELECT distance, duration, ascent, descent, ave_speed, max_speed FROM workouts WHERE id = 4;
 distance | duration | ascent | descent | ave_speed | max_speed 
----------+----------+--------+---------+-----------+-----------
    0.001 | 00:20:00 |  0.000 |   0.000 |      0.00 |      0.00
(1 ligne)

just a question: in the example the distance is 0.001km (1m). Unless I'm mistaken, the value seems very low. Is this value correct?

[dkm]

As said above, I'm using the smallest value possible as a workaround for being forced to use a non-zero one. When doing paragliding, you really only count the distance when doing cross-country flights. Anything else (hike and fly, acro, ...), you're not counting. So that's me trying to use fittrackee as a flightlog.

[SamR1]

OK, thanks for the explanation .

[SamR1]

With the fix, the workout will be displayed as follows (FitTrackee is not really designed to handle workouts without distance):

Just for information, ascent and descent are not mandatory when adding a workout without a gpx file.

Nice, thanks! I'm planning on seeing how the displayed info can be customized per sport (I.e. we don't use the GPS distance when measuring the distance in paragliding), but that will be for later :)
