1. GDPR ! Django Eleni Lixourio, | @geekfish_ | Python DBBUG
2. GDPR? Eleni Lixourio, | @geekfish_ | Python DBBUG
4. GDPR is about... cookie popups user data! Eleni Lixourio, | @geekfish_ | Python DBBUG
5. "Can I have my data?" — a user Eleni Lixourio, | @geekfish_ | Python DBBUG
6. "Umm yeah, if you could you fetch their data that'd be great" — a manager Eleni Lixourio, | @geekfish_ | Python DBBUG
7. Off to the Users table! Eleni Lixourio, | @geekfish_ | Python DBBUG
9. It's not that I'm lazy... ...it's just that there's an easier way! Eleni Lixourio, | @geekfish_ | Python DBBUG
10. Django is already solving this! Eleni Lixourio, | @geekfish_ | Python DBBUG
11. class Book(models.Model): author = models.ForeignKey(User, on_delete=CASCADE) vs CREATE TABLE books ( FOREIGN KEY (author_id) REFERENCES users (id) ON DELETE CASCADE ); Eleni Lixourio, | @geekfish_ | Python DBBUG
12. ON DELETE CASCADE "No, thanks. I like mine be3er" — Django Eleni Lixourio, | @geekfish_ | Python DBBUG
13. Django admin • Please don't use it. ... but it does some things pre1y well Eleni Lixourio, | @geekfish_ | Python DBBUG
15. Neat Eleni Lixourio, | @geekfish_ | Python DBBUG
16. from django.contrib.admin.utils import NestedObjects def collect_user_data(user): collector = NestedObjects(using="replica") collector.collect([user]) return collector.data > pprint(collect_user_data(user)) > OrderedDict([(<class 'my_app.models.User'>, > {<User: eleni@wordsandcode.co.uk>}), > (<class 'my_app.models.Event'>, > {<Event: Python DBBUG>, <Event: Python Dojo>})]) Eleni Lixourio, | @geekfish_ | Python DBBUG
17. Expand! Eleni Lixourio, | @geekfish_ | Python DBBUG
18. def collect_user_data(user): collector = CustomUserCollector(user) collector.collect_all() return collector.data Eleni Lixourio, | @geekfish_ | Python DBBUG
19. from django.contrib.admin.utils import NestedObjects class CustomUserCollector(NestedObjects): def __init__(self, user, *args, **kwargs): self.user = user kwargs['using'] = "replica" super(CustomUserCollector, self).__init__(*args, **kwargs) def collect_all(): self.collect_from_db() self.collect_from_nonrel() self.collect_remote() # ...
