Using multiple PostgreSQL schemas with Rails models
PostgreSQL adapter schema_search_path in database.yml does solve your problem?
development:
adapter: postgresql
encoding: utf-8
database: solidus
host: 127.0.0.1
port: 5432
username: postgres
password: postgres
schema_search_path: "discogs,public"
Or, you can to specify different connections for each schema:
public_schema:
adapter: postgresql
encoding: utf-8
database: solidus
host: 127.0.0.1
port: 5432
username: postgres
password: postgres
schema_search_path: "public"
discogs_schema:
adapter: postgresql
encoding: utf-8
database: solidus
host: 127.0.0.1
port: 5432
username: postgres
password: postgres
schema_search_path: "discogs"
After each connection defined, create two models:
class PublicSchema < ActiveRecord::Base
self.abstract_class = true
establish_connection :public_schema
end
class DiscoGsSchema < ActiveRecord::Base
self.abstract_class = true
establish_connection :discogs_schema
end
And, all your models inherit from the respective schema:
class MyModelFromPublic < PublicSchema
set_table_name :my_table_name
end
class MyOtherModelFromDiscoGs < DiscoGsSchema
set_table_name :disco
end
I hope it helps.
The correct one for rails 4.2 is as:
class Foo < ActiveRecord::Base
self.table_name = 'myschema.foo'
end

In migrations:
class CreateUsers < ActiveRecord::Migration
def up
execute 'CREATE SCHEMA settings'
create_table 'settings.users' do |t|
t.string :username
t.string :email
t.string :password
t.timestamps null: false
end
end
def down
drop_table 'settings.users'
execute 'DROP SCHEMA settings'
end
end
Optional in model
class User < ActiveRecord::Base
self.table_name 'settings.users'
end
Because set_table_name
was removed, and it was replaced by self.table_name
.
I think you should code follow as:
class Foo < ActiveRecord::Base
self.table_name = 'myschema.foo'
end
