Hi,

I got a production server where I’d like to run “rake test” - to check  
for file permissions etc. - all tests pass on my local machine.

On the production server I got production db and empty development and  
test db. How to create schema.rb file and prepare test db? I tried  
various rake tasks, but the schema definition in schema.rb file is  
empty and despite the fact that rake tasks (i.e. db:test:prepare and  
db:schema:dump) do not return any errors, I can’t create test db  
structure and run tests.

Thanks in advance for any tips

Try this…

rake RAILS\_ENV=development db:migrate  
rake db:test:prepare
