The main problem is that if you dump a migration and then try to run the migrations again, django will not recognize the changes you’ve made and will instead re-run the original migration.
I am trying to dump my previous migrations in Django. I have tried the following command: <code>python manage.py dumpdata --exclude contenttypes --exclude auth.permission > app/fixtures/initial_data.json</code> However, this only dumps my current data and not the data from my previous migrations. How can I do this? A: You can use <code>--format=json</code> to export your data into a json file and then you can use it as a fixture for your future migrations: <code>python manage.py dumpdata --format=json --indent=4 > app/fixtures/initial_data.json # add all your apps here separated by spaces </code>
What is dump
Dump is a command line tool for dumping the contents of a database to a text file.
Wot to make migrations in Django
There are a few different ways to migrate your data in Django 1.8.
1. Use the migrate command to run a series of migrations on your development server:
$ python manage.py migrate
2. Use the django-migrate tool:
$ pip install django-migrate $ cd myproject $ django-migrate init $ python manage.py migrate
