same errors.

Here is my articles app structure and admin.py:


And here is my site structure:


Thank you!!

updating model breaks admin

[Gloria Elena]

Hi all,

I want to request your help and I am sure you can guess by the question
that I am fairly new to Django and THANK YOU IN ADVANCE, I would like to,
someday, publish this portfolio website. I am sure I am making such a
rookie mistake and will have to kick myself for making such a silly error
but I am stuck !! Hope to pay it forward.

*I have this model in the articles app that works great: *

class Article(models.Model):
title = models.CharField(max_length=120, unique=True)
body=models.TextField(max_length=600)
date=models.DateField()
created = models.DateField(auto_now_add=True)
featured=models.BooleanField(default=False)
slug = models.SlugField(blank=True)


*UNTIL I add a new class and add this field:*

tags = models.ManyToManyField(Tag)


*Error message when adding a new article in admin:*


* OperationalError at /admin/articles/article/add/cursor
"_django_curs_5508_1" does not exist Error message when adding a new tag in
admin: *


* ProgrammingError at /admin/articles/tag/add/relation "articles_tag" does
not exist LINE 1: SELECT (1) AS "a" FROM "articles_tag" WHERE
"articles_tag".".. What I have tried to no avail:1) deleting all articles2)
migrate & makemigrations 3) deleting any references to tags in my
templates4) searching these errors on stackoverflow *
