sails-migrations provides an easy way to manage database migrations with sails, based on the amazing https://github.com/tgriesser/knex lib. This means you can have fine-grained control over your schema/data transformations between versions.
sails-migrations supports sails versions 0.9X up to 0.11.2, for both MySQL & PostgreSQL.
Please let us know if you encounter any problem working with sails-migrations by opening an issue.
As of version 2.0 we've moved to using knex schema builder.
sails-migrations up until (including) 0.1 supported Sails versions 0.9 & 0.10RC8
When upgrading to 2.0, notice that you'll need to change your old migrations code to work with knex instead of waterline.
DB migrations allows you to change your database schema/data in a controlled way by making small atomic/ordered data to your DB, for a better answer, read this
npm install -g sails-migrations
this will install the global CLI sails-migrations.
Next you'll need to install sails-migrations within the project you would like to work on:
npm install --save sails-migrations
Fairly simple, there are a few basic commands
db:drop- Just as the name suggests, reads your sails config, and DROPS the db. use with care.
db:create- Same but different, creates the db you specified in your sails config.
generate <name>- Generate a new blank migrations file, after you run this command, you need to open the new file, which by default is saved to
\db\migrations\, after you run this command, you should open this file, and put your migration information. for the migration syntex, please refer to the Knex documentation
migrate- Runs all the not-yet-runned migrations from the last run of migrate, all of those migrations are saved as a
rollback- Runs the revert function on each migration in the last
status- Prints a nice table of all the committed/uncommitted migrations.
You can checkout some example Sails apps.
For a list of commands, simply run sails-migrations from your command prompt.
For a more detailed documentation, please refer to http://knexjs.org/ A migration constitutes of two parts:
up: determines what should be performed when you want to forward your database to this version.
down: should be the exact reverse of the up method, so, for example, if on the up phase you created a table, the down phase should delete that table.
