Autoload classes on start to have TAB autocompletion

[BartlomiejSkwira]

When I launch rails console (which defaults to pry) at start there is no class tab autocompletion, for example (assuming that I have a model named User):

rails c
=> pry(main)> U[TAB] //nothing, but when I launch show-model
=> pry(main)> show-model //this loads all classes including models
=> pry(main)> U[TAB] 
=> pry(main)> User

Is there a way to autoload classes the way show-model does?
