我需要在我的Django模型的一个领域增加一个FFLLTEXT指数,并理解没有建立功能来做到这一点,这种指数必须用手法添加(背后是银)。
我希望,这一指数将在每一个环境中制定。 我理解,模式变化可以处理詹戈南部移民问题,但我是否可以在移民中增加这种“未来”指数?
总的来说,如果存在任何需要管理的习俗,我如何能够使其成为移民的一部分。
Thanks.

你可以把任何东西写成移民。 这一点!
页: 1 py schemamigration myapp --empty my_custom_migration to establish a blank migration that You can specifiede.
开放XXXX_my_custom_migration.py
file in myapp/migrations/
, and打上forwards/code> 方法的贵国海关移徙类型。 例如,您可使用http://south.aeracode.org/wiki/db.execute”rel=“noreferer”>>
db.execute
。
移民可以这样看待:
class Migration(SchemaMigration):
def forwards(self, orm):
db.execute("CREATE FULLTEXT INDEX foo ON bar (foobar)")
print "Just created a fulltext index..."
print "And calculated {answer}".format(answer=40+2)
def backwards(self, orm):
raise RuntimeError("Cannot reverse this migration.")
# or what have you
$ python manage.py migrate myapp XXXX # or just python manage.py migrate.
"Just created fulltext index...."
"And calculated 42"
在Django的新版本中,你可以创造空洞的移民,以实施习俗 s:python3.py makemigrations -empty app_name
。
Then, in the generated migration:
from django.db import migrations
class Migration(migrations.Migration):
operations = [
migrations.RunSQL(
sql="CREATE FULLTEXT INDEX `index_name` on table_name(`column_name`);",
reverse_sql="ALTER TABLE table_name DROP INDEX index_name"
)
]
