Forecast and earthquake problems in Belchertown skin

[John Clark]

(sorry for dupe message, forgot to reply to group)

BTW, if both the dark sky and earthquake settings are disabled in Belchertown/skin.conf  all runs well.

Checked (and modified) permissions to ensure write permissions  on

/home /weewx/public_html/json/darksky_forecast.json and the error messages are unchanged.

I suspect it may be a permissions issue - check the permissions for the directory and file to ensure they are correct.

FYI weewx has not locked up - it still appears to be running doing whatever tasks it can even though the cheetah generator has exited - which will result in a lack of updated reports of course.

I could be wrong in my assessment, but my weewx locks up and doesn't update. I am assuming that what is meant by public_html/json/darksky_forecast.json is referring to
/home /weewx/public_html/json/darksky_forecast.json which DOES exist, but isn't getting written to. Is my assumption in error and I should look elsewhere for the answer?

also permissions on the json directory

[John Clark]

p.ublic_html, json, and darksky_forecast.json all show  Mode: drwxrwxrwx (0777)

weewx shows Mode: drwxr_xr_x (0755) This, I assume, is supposed to be on my computer, not the web server?

[gjr80]

The issue has nothing to do with permissions, if you look at the error message carefully you will see that the file being written includes a relative path, but relative to what? Just as you were confused about what it was referring to so to is python confused. What ever python is using as the current directory does not have a public_html/json directory so the error is thrown. Pat will need to look at his code, I suspect he needs to make sure his path is relative to WEEWX_ROOT.

As an aside, a default weeWX install sees the weeWX daemon run as root so in such cases permissions are rarely an issue. Running weeWX directly may cause permission issues unless sudo or other privileged access is used.

tx Gary - yea I missed the relative bit - so Pat needs to either be relative to WEEWX_ROOT (or change the path if he is relative to HTML_ROOT) I guess.

[Pat]

If you leave HTML_ROOT as "belchertown", weewx will do the rest to put it into a sub directory of the StdReport's HTML_ROOT. 

Earthquake and Forecasts use these settings:

earthquake_file = self.generator.skin_dict['HTML_ROOT'] + "/json/earthquake.json"

forecast_file = self.generator.skin_dict['HTML_ROOT'] + "/json/darksky_forecast.json"

John, I'm wondering if within weewx.conf, what do you have under [[Belchertown]] for HTML_ROOT = public_html?

[John Clark]

If it makes any difference (although I don't think it does on this case) I did the python install and the command I use to start is sudo /etc/init.d/weewx start. Also, since sudo wee_extension --install weewx-belchertown-0.1.tar.gz  didn't work I just copied the contents to the skin directory

You should probably use version 0.4 now.

Did you follow all of Pat's instructions on GitHub for doing a manual installation?
