You need to undestant that &:primary_company is just shorthand which
is (basically even though that's not quite how it's implemented)
equivalent to
@project_companies = @projects.group_by {|project|
project.primary_company }
and now it's easy to change that to
@project_companies = @projects.group_by {|project|
project.primary_company.name }
