I have something like the following defined
desc 'prompt are you sure'
task :are_you_sure do
unless ENV['FORCE'] == 'true'
puts ""
puts "THIS WILL BLOW AWAY THE DATABASE"
puts "hit enter to continue (control c to abort)"
puts ""
STDIN.read(1)
end
end
task :refresh => %w(are_you_sure db:pull db:convert db:test:prepare)
rake db:refresh prompts
rake db:refresh FORCE=true does not
Or if you wanted to require FORCE=true, you can do the following:
desc 'require force param'
task :require_force do
raise "This modifies production. To run, please specify FORCE=true" unless
ENV['FORCE'] == 'true'
end
--K
