问题
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
回答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

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.
回答3:
$python manage.py syncdb --migrate
this migrates what has to be migrated
worked for me (django 1.4)
回答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.
