Bug with migrate appears if you try to change the db_table value

[lao zzzi]

Problem appears after renaming db_table, if you try to rename, for example "Article" to "article" or "Blog" to "blog" or to "bLoG", etc.

Example:

Step 1. Create model:

class Article (models.Model):

class Meta():

db_table="Article"

title = models.CharField(max_length=200)
body = models.TextField()
date_cr = models.DateTimeField()

Step 2. make migrations & migrate

Step 3. change the value of db_table from "Article" to "article"

Step 4. make migrations

Step 5. migrate -- here you'll see errors
.....
django.db.utils.OperationalError: there is already another table or index with this name: article

This error appears any time later, if you try to do something with model and use migrate. Even if you delete the Article model and start "make migrations & migrate" you'll see such error.
