Gpx export

[ayonix]

The current prototype exposes an endpoint to download a drive as a gpx file.
The drive details dashboard would have a link to the endpoint, so you could directly download the file from the dashboard.

As a note: I don't exactly know the details and features of GPX but as a minimal solution a list of trackpoints should be sufficient.

This is an effort to implement #722

Todos:

• Test the endpoint/view

Cool! I really like the simplicity of the integration with the dashboard.

[ayonix]

I think it might be tested enough now, but as always, if you have any concerns, let me know :)

In the future it might be better to have a real gpx library/implementation, since i'm really not sure what I'm breaking with this.
Also the newlines take some unneeded space, but this should be easy to fix

[ayonix]

Is there anything I should do or you want to have improved? :)

[adriankumpf]

Sorry for the delay. The changes looks very good! 🙌 I only noticed one small thing regarding the sorting, which can cause drives to look like this:

[adriankumpf]

Here we cannot rely on the standard sorting:

  import Ecto.Query

  drive =
    Drive
    |> Repo.get(id)
    |> Repo.preload(positions: from(p in TeslaMate.Log.Position, order_by: p.date))

[adriankumpf]

To test the date-based sorting, a third Position with a date in the past could be inserted here.

[ayonix]

Done as suggested :)

Thank you! 🙏

Hello, is it also possible to export all trips to a GPX file - i.e. my complete TeslaMate. Preferably a GPX file for every trip. The way I see it, this is currently only possible manual?

[ayonix]

Yes, currently this would only be possible manually/programmatically. You could write a script that iterates over ids 1 to n, where n is the currently highest id and downloads the file under /drive/$n/gpx.
Then you'd also have one file per drive.

[LukeSkywalker993]

The the answer. Unfortunately I can't program, so I hope that an export function will come up.

[DrMichael]

That caught me. Pls find attached a small python3 script. You need to install python3-psycopg2, either with sudo apt install python3-psycopg2 or with pip install psycopg2. And you must set the parameters for the database, either from environment or directly in the program.

Then you need to call it with the drive id... It writes the route to out.xml.

[DrMichael]

Ok, I tweeked it a bit. Now it asks for From, To and CarID. If you give an empty input, then it defaults to last 24 hours and car no 1. It now produces a track for every drive.

Output now is out.gpx. You still need to set the database parameters either by environment or manually in the code.

Unfortunately I don't understand the file. I can neither query database nor program. Wouldn't it be great to have a button to download all the tracks directly from the website with the push of a button?

For example, I downloaded all my training sessions from Apple Health as a ZIP file and then put them together and have everything directly in Google Earth. What would I like in TeslaMate.

It would also be an idea that this is installed under TRIP? You can already select the start date and end date and then the card is there. Only a new button "Export GPX" would have to be installed here.
