问题
I set it up as per the documentation (I think): https://github.com/dwbutler/groupify
But then in the console:
user=User.new
group=Group.new
group.add user
user.in_group?(group)
=> false
Returns false, instead of true.
Problem.
I don't get it. I've a few different things and no joy. I'm stuck.
My latest attempt is here: https://github.com/Yorkshireman/sebcoles/tree/setup3 (setup3 branch)
I have a previous attempt on the setup2 branch.
There is little difference between the two branches (the migrations and subsequent scheme.rb were SLIGHTLY different).
Help!

I am guessing you have to save the attributes of the group, ex: type, membership_type etc.. Also, I m guessing that the user has to be saved in the database. User.new does not save anything. Same as Group.new. User.create or User.save will help
回答2:
This is a while ago now, and I stopped using the groupify gem for my project, but I think I did get it working before I stopped using it, and I think it was actually because I was using 'group' and 'user' as the variable names (as in the above routine in the original post).
Try doing:
user1 = User.new
group1 = Group.new
group1.add user1
user1.in_group?(group1)
Should (hopefully) return true!

Make sure user.rb model includes
#For Groupify Gem
groupify :group_member
groupify :named_group_member
