Admin interface with foreign key on a very long list
If your application has a model with a ForeignKey on an other model which gets a lot of entries in the database, the auto-generated admin interface can become a nightmare to load. Django will render your ForeignKey using a select drop-down and with thousands of entries loading time and browser memory are in bad shape.
Solution is rather simple, add your ForeignKey in the raw_id_fields parameter in the Django admin. Lets consider this example :
models.py
class MyModel(models.Model):
user = models.ForeignKey(User)
admin.py
from models.py import MyModel
class MyModelAdmin(admin.ModelAdmin):
raw_id_fields = ("user",)
admin.site.register(MyModel, MyModelAdmin)
