You should be able to load your fixtures prior to entering console. Like this:
RAILS_ENV=test bin/rails db:fixtures:load
RAILS_ENV=test bin/rails console
However, you still won't be able to access your fixture data like you would in a test. This simply loads your test database with your fixtures data. So you'd still have to do something like:
user = User.find_by(name: "John")
But, you can still create shortcuts for this sort of thing. You can add any ruby code you'd like to your ~/.irbrc. I suggest creating a .railsrc file as described here. You can then set up things like:
john = User.find_by(name: "John")
So now you can just start referring to the variable 'john' after console loads. Incidentally, the post I linked to shows how to set up a global .railsrc file, but you could set it up so that you had a per project .railsrc. Or, if you want something a little less fancy, but easy to do... just create a ruby file in your project (maybe 'shortcuts.rb'). After console is loaded, just do a require 'shortcuts'.
