Re: FK constraints are not checked at the end of nested atomic blocks

I understand that a database is invalid or invalid as a whole, which is why you don't need to check constraints until transaction commit (when the transaction becomes visible to the world). Why do you want to bundle constraint checking with a savepoint release though? They seem logically unrelated.

Re: delegating our static file serving

You are free to use what your PaaS provider supplies, but if you are using heroku (and many others) you do not have a choice. If AWS allows you to use apache 2.4 in event mode, then by all means use it! But there are plenty of platforms out there where you cannot easily serve static files and/or

Re: delegating our static file serving

Just curious, about PaaS, I know AWS (Amazon) deploys python/django on apache (which is quite decent), and apache also serves static files decently. What would be wrong with this? The idea of having Python serving static files (and potentially gziping it), when python is one of the slowest langu

Re: delegating our static file serving

Also consider the media files could number into the millions (or bajizillions?). Particularly for, say, a image hosting application. Clearly it would not be feasible to enumerate all the files, and there would clearly be regular additions. It might be that this use case is simply "beyond the sc

Re: admin: implementing list_prefetch_related

Hi Richard, Overriding the queryset is a pretty simple method override, I'm not sure there is sufficient need for prefetching here. In particular, the syntax for prefetch related is much more complex than for select related, so it's less well suited to this kind of shortcut. Marc On 30 Dec 2015 1

Re: Backwards-compatibility import shims

Given that alternate, I guess I'm not really enthusiastic about making our deprecation policy more complicated. While urlresolvers is a commonly used module, updating should be a simple find and replace for the imports. On the other hand, I thought of a slight flaw in our current deprecation sc

One solution is to create a RemovedInFutureVersionWarning to allow projects to catch the change when running with -Wall, without committing to a specific release. On Wednesday, December 30, 2015 at 3:05:32 PM UTC+1, Tim Graham wrote: > > To save a link click, the question is about moving > dja

Re: Backwards-compatibility import shims

To save a link click, the question is about moving django.core.urlresolvers to django.urls and whether or not to start the deprecating of django.core.urlresolvers immediately. I don't have a strong opinion myself. On one hand, delaying gives projects more time to update, on the other, I suspect
