Re: Added new column to model and run migrations but not applied to database table

having had the unfortunate phase of dealing with it , sorting it requires some patience

the issue is the tables in django_migrations is not in sync with rest the rest of your database or migrations files. 

You have to first remove the addition in field etc and make sure the database tables are first in sync with your models, then 1. delete migrations files and 2. delete django_migrations. Then 3.makemigrations and 4. migrate fake.  All risks are yours to take

Then finally just add your fields and makemigrations and migrate

The above might/or not work as it might give some content type errors

Hi ,
Thank you for your responses.
 I have tried all the ways Which you people suggested I am not getting any error while running makemigrations or migrate and 
python manage.py migrate --fake-initial. But those migrations are not applying to the database. How can I fix this issue without deleting the database? 

Thank you

if it is saying no changes detected while running makemigrations and you are sure that you changed models.py  then these things you can try:

1: python manage.py makemigrations appname

if this will not work then do that

2: delete migrations folder from your app and delete database then run again python manage.py makemigrations

Hi all,

I have added a new column to the existing model while developing. Then I run makemigrations and migrate. It is not applied to the database table which is created based on that model. How can I fix this issue? Please help me to complete this issue.

The below issue I am facing in deployment server after adding new field and deployed into server.
