how migrate to tais? in python

To migrate from an existing database to Tais in Python, you can follow these steps:

1. Install the Tais framework using pip:

main.py
pip install tais

2 lines

2. Create a new Tais database schema and tables using the tais init command. This will create the necessary folder structure and configuration files in your project directory:

main.py
tais init my_project
21 chars
2 lines

3. Use the tais migrate command to create a new migration. This will generate a new Python script that you can use to migrate your data to the new database structure. You can provide a descriptive name for the migration:

main.py
tais migrate my_migration
26 chars
2 lines

4. Edit the migration script to define the changes you want to make to your database schema. You can use the Tais API to create new tables, modify existing tables, insert data, and more. For example, to create a new table, you can use:

main.py
from tais import database

async def up():
    await database.create_table('my_table', [
        ('id', 'integer primary key'),
        ('name', 'text')
    ])

async def down():
    await database.drop_table('my_table')

5. Run the migration using the tais migrate command again, this time providing the name of the migration script you just created. This will apply the changes to the database:

main.py
tais migrate my_migration.py
29 chars
2 lines

6. Verify that the migration was successful by checking the contents of your Tais database using the Tais console:

main.py
tais console

2 lines

From there, you can use the Tais API to query, modify, and delete data from your database.
