Is there any trivial way to copy the data from developmenet database into the test one? I know theres a way to copy schema and recreate database, but is there any rake task to p
You can use:
rake db:test:clone
To copy the development db into test.
With Postgres, copy the database like so:
CREATE DATABASE newdb WITH TEMPLATE originaldb OWNER dbuser;
An alternative method if you use seeds (db/seeds.rb)
First, add a rake task for example to lib/tasks/test_seed.rake with this code:
namespace :db do
namespace :test do
task :prepare => :environment do
Rake::Task["db:seed"].invoke
end
end
end
Then whenever you changed your database structure / content through migration and seeds, you can run
rake:db:test:prepare
To copy the schema and seed data.
So the complete steps would be:
rake db:migrate
rake db:seed
rake db:test:prepare
For all databases:
rake db:test:clone && rake db:seed RAILS_ENV='test'
If you just want to clone the development DB in its entirety, what's wrong with just copying the development.sqlite3 and renaming it test.sqlite3? You can automate the process by setting up a batch file (or its equivalent on your OS) that you can run from the command line.
This will work locally, but I just realized you might be thinking a non-local environment, in which case it probably won't.
You can use mysql directly:
mysqldump app_development | mysql app_test
