У меня есть этот код в admin.py
@admin.register(BaseFundElement)

Основная проблема связана с этим кодом

Я хочу, чтобы при нажатии на кнопку открывалась форма с моделью, которую я буду заполнять
Но это невозможно сделать . Вот модель, на которую я хочу, чтобы перенаправление пришло
@admin.register(WriteOffAct)
class WriteOffActAdmin(admin.ModelAdmin):
list_display = ('basis_for_write_off', 'total_excluded', 'submitted_by', 'registered_by')
fieldsets = (

readonly_fields = ['total_excluded']
form = WriteOffActForm
my_admin_site.register(WriteOffAct, WriteOffActAdmin)

registered_by = models.IntegerField(verbose_name="В книге суммарного учёта акт проведен")
def save(self, *args, **kwargs):
self.total_excluded = self.journal_1_count + self.journal_2_count + self.journal_3_count
super().save(*args, **kwargs)
class Meta:
app_label = 'klib'
verbose_name = "Акт списания"
verbose_name_plural = "Акты списания"
вот код самой кнопки, которая используется в моем приложении Jazzmin
{% extends "admin/change_form.html" %}
{% block object-tools %}
{{ block.super }}
{% csrf_token %}
{% endblock %}
Мой вариант не сработал
change_form_template = "klib/create_act.html"
def create_act(self, request, object_id):
base_fund_element = self.get_object(request, object_id)
if request.method == "POST":
write_off_act = WriteOffAct.objects.create()
return redirect(reverse('admin:klib_writeoffact_change', args=[write_off_act.pk]))
return self.change_view(request, object_id)
def get_urls(self):
urls = super().get_urls()
custom_urls = [
path('create_act//', self.admin_site.admin_view(self.create_act), name='create_act'),
]
return custom_urls + urls
