# Migrate

This is a work in progress.

But the basic idea is to allow for simple database migrations that are framework agnostic. After all it's just string manipultion, right?

It should be as simple as this...

```python

import migrate

class CreateUsers(migrate.Migration):

  def up():

    self.create_table('users')

    self.string('full_name')

    self.string('email')

  def down():

    self.drop_table('users')

class AddPasswordToUsers(migrate.Migration):

  def up():

    self.add_column('users', 'password_hash', 'string')

    self.add_column('users', 'password_salt', 'string')

  def down():

    self.remove_column('users', 'password_hash')

    self.remove_column('users', 'password_salt')

```

And just as simple to apply migrations, rollback and work with the data...

```bash

python migrate.py --init

python migrate.py --create_migration create_users

python migrate.py --migrate

python migrate.py --rollback --steps 2

python migrate.py --load-schema

python migrate.py --dump-schema

python migrate.py --dump-sql --migration create_users

python migrate.py --dump-sql --all

```

With a directory structure  that goes something like...

```bash

db/

  /migrations/

        20131031135212_create_users.py

        20131031135219_create_posts.py      

```
