Ошибка при миграции django и PostgreSQL
я создал модели django. Пытаюсь сделать миграции на PostgreSQL, но выдается ошибка, связанная с updated_date и timestamp.
django.db.utils.ProgrammingError: ОШИБКА: привести тип integer к timestamp with time zone нельзя
LINE 1: ...TYPE timestamp with time zone USING "updated_date"::timestam...
Уже очень долго мучаюсь, но вообще нет вариантов, как решить эту ошибку.
models.py
from django.db import models
from django_currentuser.db.models import CurrentUserField
class Docs(models.Model):
title = models.CharField('Заголовок', max_length=100)
created_date = models.DateTimeField('Дата создания', auto_now_add=True)
updated_date = models.DateTimeField('Дата последнего изменения', auto_now=True, auto_now_add=False)
created_by = CurrentUserField(verbose_name="Создал", on_delete=models.CASCADE, related_name="docs_created_by")
updated_by = CurrentUserField(verbose_name="Последнее изменение", on_update=True, related_name="docs_updated_by")
class Meta:
verbose_name = "документ"
verbose_name_plural = "Документы"
class DocsScan(models.Model):
doc = models.ForeignKey(Docs, on_delete=models.CASCADE)
image = models.ImageField('Скан документа', upload_to='additional_edu/scans/%Y/%m/%d/%H-%M-%S/')
class Meta:
verbose_name = "скан"
verbose_name_plural = "Сканы"
admin.py
from django.contrib import admin
from .models import *
# Register your models here.
class AdminDocsScan(admin.StackedInline):
model = DocsScan
max_num = 10
extra = 0
@admin.register(Docs)
class AdminDocs(admin.ModelAdmin):
inlines = [AdminDocsScan,]
fieldsets = (
(
None, {
'fields': ('title',)
}
),
(
'Дополнительная информация', {
"classes": ["collapse"],
"fields": (
'created_date',
'updated_date',
'created_by',
'updated_by'
)
}
)
)
list_display = ('title', 'created_date')
list_display_links = ('title', 'created_date')
readonly_fields = ('created_date', 'updated_date')

WARNINGS:
?: (ckeditor.W001) django-ckeditor bundles CKEditor 4.22.1 which isn't supported anmyore and which does have unfixed security issues, see for example https://ckeditor.com/cke4/release/CKEditor-4.24.0-LTS . You should consider strongly switching to a different editor (maybe CKEditor 5 respectively django-ckeditor-5 after checking whether the CKEditor 5 license terms work for you) or switch to the non-free CKEditor 4 LTS package. See https://ckeditor.com/ckeditor-4-support/ for more on this. (Note! This notice has been added by the django-ckeditor developers and we are not affiliated with CKSource and were not involved in the licensing change, so please refrain from complaining to us. Thanks.)
