Jason,

I ran into the same thing.  I don't know what it is.. but the work around is:
 var = "<" + "tag>"

Be careful, As I found, when trying to LOG stuff... XML get's wiped in the log too..
I found out the hard way while trying to log var.inspect.
it didn't work.. but the code was FINE in IRB.
With regards to the log, putc '<'
  • ; putc 32; then finish your log...

Hi all,
  I've got a new version of the weather code.  I've had this code running for a while now, just haven't had time to post it.  I was going to post it now, but everytime I try I get a error message saying 'Cannot access attachments upload path'.  I did a search, but no solutions to this were found.  Anyway the auto retrieval code is working, and I fixed the problem I was having with the editor removing my xml tags.  Since it was part of a regex I simply used the tag I am searching for without the first '<'.  The editor likes it and the regex code finds only the data I'm looking for.  Also added some more logging.  I've had it running for a couple days now and it seems well behaved so far.  I'd like to start adding data retrieval now so that other devices (and hopefully events) can get weather data whenever they want it, rather than waiting an hour to see if something changed.

Thanks,
Jason

Glad to hear that!
Adding data retrieval is almost trivial.. simply create (or use existing) commands and pass data via the command..

Great Work!

I tried again, but got the same error message 'Cannot access attachments upload path!' when trying to post with an attachment.  Any ideas?

Any spaces in the path?
Try copying the code to root, then attach that..

No luck.  The forums are giving me the error, so I'm guessing the problem is not on my end.  I did as you suggested though.  I removed all spaces from the file name and moved it to the root of my local drive.  I'm at a loss.  Being over 250 line long I don't think pasting it into a message is the best of ideas.  I'm open to suggestions though as to how to get my code up here.

Thanks,
Jason

yup, I had tried to upload a picture attachment, with the same problem.. there is a permissions problem on the attachments path.

Ok, Here's the code.  Sorry to post it inline, but uploading attachments is still broke and the original I posted is no longer available.  Have a look and let me know what you all think.

Thanks
Jason

Nice!

That is a *great* piece of code.  If I were you, I'd document that in the wiki!
the more 'sample' code we have in the wiki, the more people can see how easy Ruby really is..

Great Work!
