Let's talk with a concrete (real but simplified) example. There's a database of documents. Some documents are publicly available, whereas some are available only to logged-on users. The "document list" view shows all documents if you're logged-on, and a subset if not. The "document detail" view w

Updating files without web server restart

We have a small webserver that is used by many projects (php) from many users. Now, i am hosting a django project. The problem is: - when user changed some file in his project, the apache continues serving old file until restart the httpd service. - the users don't have sudo access, and i don't

OneToOne mappings

No support for UNION (OUTER JOIN instead)

We have performance issues on postgres because some SQL statements have up to six LEFT OUTER joins. Union and intersection would be easier to read for me (human being) and maybe better to optimize for the postgres query planer. It seems that other people have this issue, too: https://code.d

What was the rationale behind ClassBasedView.as_view()

Django views are just functions that take a request, and possibly some other args, and return a response. To get such a view from a class based view, you can `as_view()` on it. Why is that? Wouldn't it make the code neater to just implement `__call__` on the views? What was the reing behind ha

Re: Django makemigrations cannot detect change when changing custom field overriding charfield.

CategoryField subclassed CharField, so I think I don't need to add deconstruct method in CategoryField. And, when call CategoryField().deconstruct(), the values return correctly. Why django makemigrations cannot detect max_length and choices change? 2017년 3월 13일 월요일 오후 10시 43분 53초 UTC+9, Tim
