I've been working through "Practical Django Projects" by James Bennet. I came across some unexpected behaviour which I wanted to share regarding handling errors on startup within the urls configuration.
In the weblog application he talks you through, he discusses splitting up urls.py into modules. You end up with four files within a urls module. urls/entries.py urls/links.py urls/categories.py urls/tags.py Now my tags.py module had an error in it. I had restarted the server and sure enough when I went to the site (to the default entries view) it was raised. The error was a missing model import in tags.py (and that's what the error said to me). However, if I just ignored it and refreshed the screen again the error did not appear again. I'm guessing this is because Django assumes my url regexes have been compiled and it doesn't run that code again to get the error. So I'm sitting using the site thinking everything is fine but actually there's a whole bunch of urls that don't work because (I'm assuming) they would have been compiled in after the url/tags.py failed. Of course I should not have ignored the error. I foolishly thought that it was a 'glitch'. My bad. However, should Django have 'known' that it's url loading had failed and forced it to be redone when the next request came in? Could Django know that in this instance? Having a site running with your url configuration only partly loaded doesn't feel right to me. Comments welcomed. I'm not likely to make the same mistake again but interested to know if there's a solution for this. Besides the obvious "Don't ignore error messages" :) This was using the newforms-admin branch by the way, just in case anything has changed there regarding this.
