[weewx-user] Re: Including dynamic link in skin

[Pat]

The Cheetah generator can use #echo to print 
<http://cheetahtemplate.sourceforge.net/docs/users_guide_html/users_guide.html#SECTION000810000000000000000>
 the 
date (and other things)... So you can try this in index.html.tmpl:


#echo time.strftime('%Y%m%d')#

So the full line would be:

<img src="https://twc.tamu.edu/weather_images/rawsfcst/rawsfcst/#echo 
time.strftime('%Y%m%d')#.png">


Which gives me this output:

<img src=
"https://twc.tamu.edu/weather_images/rawsfcst/rawsfcst/20180916.png";>

But that img returns a 404 for me, so I think you're missing something. 
Either way, hopefully this is enough to get you started.
