I have django application, where I wanted to export all migration from my project , auth and admin to sql query. I am able to do
python manage.py sqlmigrate myapp 0001
However, I want to export all migration at same time rather than explicitly righting loops. Is there any package or tool that i can use for this.
you can use squashmigrations command
python manage.py squashmigrations <appname> <squashfrom> <squashto>
and press y
Delete all the before migration files
then run the following command
python manage.py sqlmigrate <appname> <squash_generated_migartion_file>
if you wanted to see the sql for auth migrations
python manage.py sqlmigrate auth 0001_initial
First make sure you are on directory with manage.py file i.e. project directory then, you can do
python manage.py makemigrations
and then run
python manage.py migrate or python manage.py sqlmigrate

I deleted a model in Django which I created for testing purposed. Now when I try and run makemigrations and mirgrate I get the following error:
django.db.utils.ProgrammingError: table "members_test" does not exist
Is there a standard procedure I should be doing when deleting a model? I only deleteed the code out of my Models file and tried migrating after.
I've only tried runing migrate and make migrations in addtion to scouring the web.
Simply you can delete all migrations folder and re-migrate using below command:
python manage.py makemigrations appname
python manage.py sqlmigrate appname 0001
python manage.py migrate
I'm using PostegreSQL.
What I've tryed already:
python manage.py flush
python manage.py makemigrations
python manage.py migrate
python manage.py makemigrations app
python manage.py migrate app
python manage.py migrate --run-syncdb
There aren't any effect. The table have no recently added columns.
Have no importaint data in tables, can remove it.
Delete all migration files (except the init.py files) and database, rerun makemigrations and migrate.
Remove all DB tables.
Remove all migration files from migrations directory.
python manage.py makemigrations
python manage.py migrate
I am not able to search and migrate that 1 unapplied migration.
Please help me out
run this "./manage.py makemigrations" again and migrate again.
"./manage.py migrate"
First check migrations list
python manage.py showmigrations --list
In either case, there will be an [X] to show which migrations have been applied.
If you have unapplied migrations the run the command
python manage.py makemigrations
python manage.py migrate
Run python manage.py migrate
If it doesn't work... then delete all files from migrations folder except init.py the go to database and find migrations table, delete all entries. Then again run python manage.py migrate
When I click in my table in http://127.0.0.1:8000/admin/, I see this error:
OperationalError at /admin/home/table/
no such table: home_table.
I ran Python manage.py makemigrations home, Python manage.py makemigrations and Python manage.py migrate but they didn't work.
If you're using sqlite then:
Try unapply all the migrations using using command:
python manage.py appname zero
Then apply the migrations command again. If it still doesn't work then delete your sqlite db and run migrations again. It will work.
There are three migration commands in Django:
python manage.py makemigrations
python manage.py migrate
python manage.py syncdb
In what order do these commands should be executed in terms of workflow of a basic project?
I am using Version: 1.8
syncdb is deprecated and does the same as migrate.
Whenever you make a change to your models, and when you first create them, each time you'd want to first run makemigrations to create the migration files, then migrate to apply them to your database.
