Rails migrations for postgreSQL schemas
I have a schema_utils library which I use and has the following method for handling migrations:
def self.with_schema(schema_name, &block) conn = ActiveRecord::Base.connection old_schema_search_path = conn.schema_search_path conn.schema_search_path = schema_name begin yield ensure conn.schema_search_path = old_schema_search_path end endI then use migrations as normal so I can continue to call rake:migrateNow, in your migrations you can use:
...schemas.each do |schema| SchemaUtils.with_schema(schema) do #Put migration code here #e.g. add_column :xyz, ... endendBecause I tend to be mapping schemas to account codes I do the following:
Account.for_each do |account| SchemaUtils.with_schema(account.code) do #Put migration code here endend
I'm not sure if I got the question right but don't you just need to declare a few more environments in your database.yml with different "database" specified in each?
