Doesn't work anymore with Rails 4.x

This is what happens:

$ rails g models_from_tables
"******************************************************************"
"The 'matthuhiggins-foreigner' gem has changed names to 'foreigner'"
"Install the renamed gem using 'gem install foreigner'"
"******************************************************************"

@sixtyfive I'm glad that you're finding this gem useful. I have to be honest that I haven't looked at it in several years. I'm sorry but I don't have the time to figure out what's going on and bring this up to date. I'd be more than happy if you want to fork & update this yourself and would be happy to make you the owner on rubygems so you could then push your changes.

I expect this is not the answer you are hoping for and I'm sorry I don't have the time to be of more help.

Alex, thank you for responding! Unfortunately I'm in a similar position time-wise (as probably a lot of people interested in a gem like this one might be). At least now this issue exists, so perhaps someone decides to step up...

For anyone finding this, I have successfully used this gem to build models in a dummy Rails3 app, which I then modified and dropped into a new Rails4 app. Some awk/sed steps help with this. See my comment in other thread in this issue for some steps that worked for me: https://github.com/alexrothenberg/legacy_data/issues/4
