no flot/ directory is found in OS.

the code i used is same and code file are placed in /myProjectDir/ where all the jquery files are placed which are not loading. https://raw.githubusercontent.com/electronut/pp/master/piweather/piweather.py

plz tell where to place the piweather.py file so that the server loads the jquery file and where to change the file.

i had created the issue : https://github.com/bottlepy/bottle/issues/1176 Issue is still not fixed.

i had created the issue : bottlepy/bottle#1176 Issue is still not fixed.

It is not fixed because it is not an issue with bottle, but your application. And you closed bottlepy/bottle#1176 before opening this issue, so I assume you came to the same conclusion.

@0xh0n3y But there needs to be a flot/ directory. What does the book say what you have to do to get this example up and running?

[0xh0n3y]

It's bottle server WSGIRefServer issue which doesn't load the flot files even when the flot directory is been made and contains the piweather.pi file in it. Somehow the issue has been fixed now.

It's bottle server WSGIRefServer issue

No. It's not. You either did not have a flot directory with js files in place, or started the server from a different working directory. flot is a relative path (same as ./flot/) so the current working directory matters. There is no bug or issue with bottle and/or WSGIRefServer.

[0xh0n3y]

All the js files have been in flot directory i followed all the steps according to book and also created a flot directory where all the js files are placed but server was not able to load js flot files from the python piweather.py code .

[0xh0n3y]

Firstly as i followed the steps acc. to book it had created /home/pi/myProjectDir/ and acc. to that flot is been moved to myProjectDir/ but it won't work then after i moved it to the /root/flot directory by manually creating that directory and run the code from that directory but it won't either and you think i didn't tried that.

[0xh0n3y]

Issue wasn't fixed i changed my mind to switch to the different method to get temperature and humidity sensor data from DHT11 but if you can tell me in which directory i should the code of flot and where to keep the piweather.py file. One thing i should make clear is that js flot can't plot the data on the localhost and which specific ip address should i use with the piweather.py file while executing the code from terminal.

Software does not magically not work and then fix itself. Neither bottle nor WSGIRefServer changed between your first try (which did not work) and your last (which did work, apparently?). So you must have changed something yourself. If you want to learn anything from this issue, find out what the difference was, and understand why it makes a difference.

Again: The current working directory (the directory you are in when you start a python program) does matter. piweather.py will look for js files in ./flot/ directory relative to the current working directory, and NOT relative to itself.

File permissions also matter. If you run piweather.py as the user pi but created the flot directory as root, then bottle won't be able to read these files.

[0xh0n3y]

I will be checking it for few minutes don't close the issue.

[0xh0n3y]

Man i tried alot eve changing the permissions for the file but it does fix the issue.Can you suggest something.

If you are in ~/flot/ and starting piweather.py, it will search for static files in ~/flot/flot/ which does not exist. I'm not sure what is so hard to understand here.

[defnull]

It should look like this:

~/myProject/piweather.py
~/myProject/flot/jquery.js
~/myProject/flot/... (more js files)

Then go to ~/myProject/ and run python piweather.py --ip localhost --port 8080.

Server error fixed . Thanks man. Issue fixed . Project done.
