Django Field Notes

Model + Form validations

Some of Django's choices on how to handle data integrity are wrong, or at the very least, unexpected to the uninitiated developers. I'm not here to pass judgement; like many people, I'd just like to get back to doing real work. Some notes on how to stay safe in Django:

What should I know?

  • Django now has both Form validations and Model validations
  • Django used to only have Form validations
  • Form’s is_valid() performs model validation automatically
  • full_clean() is never actually called by Django (see ticket #13100)

Carrierwave custom store_path

Carrierwave recommends overriding store_dir in the uploader, but it only gives you a way to modify the directory name, not the whole path with the file name. Overriding store_path let's you modify the entire path.

def store_path(for_file = filename)
  self.model.class.name.underscore.pluralize + "/" + self.model.slug + "/" + (version_name || :original).to_s + ".jpg"
end

This is the original:
