django modify the database table names

premise

Database table name automatically generated, generated in accordance with APPname + table name, but because the interface needs, table name may not be such a configuration, only the name of the table themselves, can not add a prefix, the records about the modification process and commands.

Django Version: 1.6

Step 1: Generate empty file to record changes

命令：python manage.py schemamigration appname --empty name_of_migration

appname:app的name根据实际情况
name_of_migration：最终生成修改记录文件的名称，可以用这个也可以随便取一个别的，就是0001开头的文件，自动保存在migrations目录下

Step two: modify the generated files

打开第一步生成的文件
修改如下部分内容
class Migration(SchemaMigration):
def forwards(self, orm):
        db.rename_table('yourapp_foo', 'yourapp_bar')
def backwards(self, orm):
        db.rename_table('yourapp_bar','yourapp_foo')   

旧名字：yourapp_foo
新名字：yourapp_bar(这里可以用appname+名字，也可以直接写名字)

The third step: Synchronize Database

python manage.py migrate appname
