Rubymine does not save database configurations. It always reloads it from the database.yml
This is true even with the 'save on disk with master password protection'
So every time I load rubymine, the DB configs are always repopulated with non-working values, since I use ERB in database.yml.
I see a pile of database error balloons telling me about problems that are really of rubymine's own making.
I'm using Rubymine 7.1 RTM. Same problem occured on the RC
