How can I append options to "rake db:migrate"?

[yangzhichina]

Hi, Guys,

I was deploying a project to my server with Mina, but it failed to migrate DB. The output on screen told me to add --trace to check what was going on. After checking the source code, I was not able to know how to add an option such as --trace to rake db:migrate (the final command will be rake db:migrate --trace).

Should I add a new var via set, then append the new var to #{echo_cmd("#{fetch(:rake)} db:migrate")}}, or write a new task in my own config/deploy.rb?

Thanks.

Sorry, I found there is a doc for my question. Write your own task
