404 and 500 errors in django

Problem: Server Error 500. In the server log, all it mentions is a line that looks something like "GET / HTTP/1.1" 500 27 Potential fix: There are two potential reasons for this error. Ensure that ALLOWED_HOSTS is configured properly in the settings file. In the default settings file, there's a line for ALLOWED_HOSTS=[]. In my case, I was deploying things locally, so I edited this line to be ALLOWED_HOSTS=['127.0.01','localhost']. If you're deploying things on a specific domain, list that here. Others have suggested using ALLOWED_HOSTS=['*'], but this setting should really only be used for testing deployments, as it's not…Read more …

getting DEBUG=FALSE to work correctly

Problem: Static resources (images, js, css, etc.) lead to 404 errors. Potential fix: A similar question was posted here and here. This is actually by design, as django is not meant to server static resources when DEBUG=False. Basically, when you're in DEBUG mode, static files are being served via the staticfiles app (which uses settings like STATICFILES_DIRS and STATICFILES_FINDERS to properly locate your static resources). When DEBUG=FALSE, the staticfiles app doesn't run and your static resources aren't being referenced correctly by the django webserver. However, if you were to host the files are…Read more …

django + less, updated

In a previous post, I described how I configured the hyperkitty django project to use LESS. Briefly, my steps were: - install django-compressor, django-less, nodejs, npm, and lessc - update settings.py with configuration settings for django-compressor and django-less - restart webserver However, it turns out some of those steps are a bit outdated. First, PyPI says that django-less is not maintained and suggests using django-static-precompiler instead. Second, while LESS suggests that the easiest way to install the compiler is via npm, it is just as easy to install the LESS compiler via nodejs-less.…Read more …

django + less setup

While working on the front-end for hyperkitty, I was running into a lot of repetitive css. Now, I don't mind being a bit quick and dirty just to get things working quickly, but for long-term maintanance I thought it would be better to look into some stylesheet languages. Since hyperkitty is using Bootstrap, I naturally looked towards LESS. LESS has features like variables, extension, and nested rules, which makes CSS stylesheets look much more readable (and will hopefully mean it'll be easier to maintain moving forward). To get LESS working with hyperkitty's development…Read more …
