assignable? is just a filter to select roles that have attribute
assignable set to true.
Regarding roles... I want to select not all roles, but roles that are
members of project. And also I cannot change database structure. So I
have the following entities relations:
Roles - Members -

If you want a list of roles, why would you go through the members
table to get it? You can just do Roles.find(:all).map(:name)
I'm not sure what you doing with assignable?. It seems to be
important to you, but you have not explained what it is supposed
