Hello,
Thanks for this library, it'll really help me out. I'm a little
stuck on getting bootstrapped, can you perhaps give me some guidance ?
Basically I'm stuck at step 5, attempting to create my first
migration, what am I missing ?
Thanks,
Edmund
-----------------------------------------------------------------
Steps taken
1. Added to :dev-dependencies in project.clj
[drift "1.4.0"]
[org.drift-db/drift-db-mysql "1.0.4"]
2. Created a table to hold the version number inserted 0
create table schema_migrations (
version int not null primary key
) engine InnoDB;
3. Created src/config/migrate_config.clj
(ns config.migrate-config
(:require [clojure.contrib.sql :as sql]))
(defonce DB (atom {:classname "com.mysql.jdbc.Driver"
:subprotocol "mysql"
:subname "//mysql-server:3306/bookkeeper"
:user "user"
:password "password"
:auto-commit true
:fetch-size 500}))
(defn db-version []
(sql/with-connection DB
(sql/with-query-results res
["select version from schema_migrations limit 1"]
(:version (first res)))))
(defn update-db-version [version]
(sql/with-connection DB
(sql/insert-values :schema_migrations [:version] [version])))
(defn migrate-config []
{:directory "/db/migrations"
:current-version db-version
:update-version update-db-version})
4. Run lein deps to grab the deps
5. Attempted to create a migration, or get something going
$ lein create-migration first
