In the process of learning Django and Python. I can't make sense of this. (Example Notes:'helloworld' is the name of my project. It has 1 app called 'app'.) from helloworld.views import * # <<-- this works from helloworld import views # <<-- this doesn't work from helloworld.app import views # <<-- but this...

Hi. I posted this in the mailing list, but the reply I got wasn't too clear, so maybe I'll have better luck here. I currently have a grid with data in it. I would like to know if there is a way to give each generated row an ID, or at least, associate each row with an object. It may make it more clear if I clarify what i'm doing. It is ...

I need to detect when a program crashes or is not running using python and restart it. I need a method that doesn't necessarily rely on the python module being the parent process. I'm considering implementing a while loop that essentially does ps -ef | grep process name and when the process isn't found it starts another. Perhaps thi...
I'm trying to implement a WikiLink template filter in Django that queries the database model to give different responses depending on Page existence, identical to Wikipedia's red links. The filter does not raise an Error but instead doesn't do anything to the input. WikiLink is defined as: [[ThisIsAWikiLink | This is the alt text]] Her...
