Django syncdb and migrate

Question

I'm moving django website from one server to another, and I tried to syncdb, so i've put python manage.py syncdb, and i get this output:

Syncing...
Creating tables ...
The following content types are stale and need to be deleted:

    orders | ordercontact

Any objects related to these content types by a foreign key will also
be deleted. Are you sure you want to delete these content types?
If you're unsure, answer 'no'.

    Type 'yes' to continue, or 'no' to cancel: no
Installing custom SQL ...
Installing indexes ...
No fixtures found.

Synced:
 > django.contrib.auth
 > django.contrib.contenttypes
 > django.contrib.sessions
 > django.contrib.sites
 > django.contrib.messages
 > django.contrib.admin
 > django.contrib.admindocs
 > django.contrib.markup
 > django.contrib.sitemaps
 > django.contrib.redirects
 > django_filters
 > freetext
 > sorl.thumbnail
 > django_extensions
 > south
 > currencies
 > pagination
 > tagging
 > honeypot
 > core
 > faq
 > logentry
 > menus
 > news
 > shop
 > shop.cart
 > shop.orders

Not synced (use migrations):
 - dbtemplates
 - contactform
 - links
 - media
 - pages
 - popularity
 - testimonials
 - shop.brands
 - shop.collections
 - shop.discount
 - shop.pricing
 - shop.product_types
 - shop.products
 - shop.shipping
 - shop.tax
(use ./manage.py migrate to migrate these)

Next step was python manage.py migrate, and this is what I've got:

Running migrations for dbtemplates:
 - Migrating forwards to 0002_auto__del_unique_template_name.
 > dbtemplates:0001_initial
 ! Error found during real run of migration! Aborting.

 ! Since you have a database that does not support running
 ! schema-altering statements in transactions, we have had
 ! to leave it in an interim state between migrations.

! You *might* be able to recover with:   = DROP TABLE `django_template` CASCADE; []
   = DROP TABLE `django_template_sites` CASCADE; []

 ! The South developers regret this has happened, and would
 ! like to gently persuade you to consider a slightly
 ! easier-to-deal-with DBMS.
 ! NOTE: The error which caused the migration to fail is further up.

_mysql_exceptions.OperationalError: (1050, "Table 'django_template' already exists")

My question is do I need to remove tables django_template and django_template_sites from MySQL? Both tables are empty.

I'm running on CentOS 6, django 1.3.1, python 2.6

Answer 1

Try

syncdb --all 

as I have the same problem and --all just works.

I found this solution here https://github.com/divio/django-cms/issues/1343

Answer 2

This might help others going through the same issue.

Since your database is to be created now and there are no migrations needed, after doing what Ahmad mentioned, also do a fake migration so south will mark all migration scripts as already run. In short, run these.

syncdb --all
migrate --fake

Please note that if you already have data in your database you shouldn't use syncdb --all.

Answer 3

$python manage.py syncdb --migrate

this migrates what has to be migrated

worked for me (django 1.4)

Answer 4

Another alternative is mark that first migration as done:

./manage.py migrate dbtemplates --fake 0001

It seems to be that you already have in your database the schema that you want to create.
