Custom SimpleListFilter Subclass for DjangoAdmin

Tag : python , By : cheese_doodle
Date : March 29 2020, 07:55 AM
it fixes the issue You need two list_filters, one for the maximal date and one for the minimum date. Query your entries for all distinct years. Something like this:
class MaxDateListFilter(SimpleListFilter):
    title = _('maximum date')
    parameter_name = 'max_date'

    def lookups(self, request, model_admin):
        return [(str(year.year), year.year) \
                 for year in Entry.objects.dates('pub_date', 'year')]

    def queryset(self, request, queryset):
        return queryset.filter(pub_date__year__lte=self.value())

Copy value from different model when DjangoAdmin creates object

I hope this helps . You can use Django's post-save signal:
Create signal receiver:
# models.py

def history_add_price(sender, instance, **kwargs):
    if not instance.price and instance.object and instance.object.price:
        instance.price = instance.object.price
    return True
# models.py
from django.db import models 

models.signals.post_save.connect(history_add_price, sender=History, dispatch_uid="add_price_post_save", weak=False)

it should still fix some issue The solution to add another button is here: Create custom buttons in admin change_form in Django
You can add your url easily to the button using the reverse of the django admin: https://docs.djangoproject.com/en/2.0/ref/contrib/admin/#reversing-admin-urls

I hope this helps . In Django 2.0 the support for allow_tags in ModelAdmin methods was removed:
return mark_safe(devices_with_links)

DjangoAdmin has_delete_permission executed from another Admin Class

Tag : python , By : somebody

should help you out This happens because of one method of the class AdminSite : each_context.
def each_context(self, request):
    Return a dictionary of variables to put in the template context for
    *every* page in the admin site.

    For sites running on a subpath, use the SCRIPT_NAME value if site_url
    hasn't been customized.
def get_model_perms(self, request):
    Return a dict of all perms for this model. This dict has the keys
    ``add``, ``change``, ``delete``, and ``view`` mapping to the True/False
    for each of those actions.
    return {
        'add': self.has_add_permission(request),
        'change': self.has_change_permission(request),
        'delete': self.has_delete_permission(request),
        'view': self.has_view_permission(request),
