Question

Ok i had this working and i’m not sure what i could have changed to make rake db:create not working now. I ran rake db:drop to drop my db so i can start from scratch and now rake db:create is having a problem.

Here’s my stacktrace below. I’m not sure how to go about troubleshooting this.

$ rake db:create --trace
** Invoke db:create (first_time)
** Invoke db:load_config (first_time)
** Invoke rails_env (first_time)
** Execute rails_env
** Execute db:load_config
** Execute db:create
rake aborted!

Answer 1

When you have extra leading spaces before a key in your YAML file it is interpreted as a sub-key, and thus the upper key is interpreted as a hash instead of a string. So removing the extra space before socket in the test section should fix the problem.
