Rails 3. Creating a production database

问题

How can I create a production database in Rails 3 and load a schema to it?

I tried the following approaches...

I.

rake db:create Rails.env='production' && rake db:schema:load Rails.env='production'

II.

# config/environment.rb
# Set the rails environment
Rails.env='production'
rake db:create && rake db:schema:load

... but neither of them works.

Thanks.

回答1:

You can set the rails env off of the environment variable RAILS_ENV

RAILS_ENV=production bundle exec rake db:create db:schema:load

should work

回答2:

Shouldn't this be

RAILS_ENV=production bundle exec rake db:create db:schema:load
