Django South migration - Add.FULLTEXT Index
原标题:Django south migration - Adding FULLTEXT indexes

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"
        )
    ]
