Here's how to find the 10 closest locations to a point for a model that has latitude and longitude columns, if you're not using GeoDjango.
This runs a brute force distance calculation against every row, so it should only be used on smaller tables - probably less than 100,000 rows.
For larger tables you should use GeoDjango instead.
See also [my TIL](https://til.simonwillison.net/postgresql/closest-locations-to-a-point) about this.
A simple jQuery javascript that collapses all stacked inline rows for better handling of large inline fieldsets.
It also adds "Show"/"Hide"-buttons for showing/hiding each row, which could be customized and styled using css.
**Usage (see below for example):**
Include the javascript on your admin page, together with jQuery, and it'll automatically affect all stacked inlines.
**Works with**
Django 3.1.4
(Might work with other versions with or without adjustments, but not tested)
**Use example:**
*admin.py:*
class DateInline(admin.StackedInline):
model = Date
extra = 10
class EventAdmin(admin.ModelAdmin):
inlines = [DateInline]
class Media:
js = ['js/collapsed-stacked-inlines.js']
admin.site.register(Event, EventAdmin)
A minimally invasive Select widget that looks and acts like a disabled select input, but still submits with the form. It works by rendering the form as disabled, and supplements it's output with a hidden input field with the same name and value.
Tested in Django 3.0, probably works in Django 1.11+
