Hi, it seems that you’re trying to access an attribute of a User table
called size and
this isn’t possible with the above. Thus, you’ll need to do something
like
the following:

Report.all( :joins => :user, :group => “user_id”, :order => “size desc”
)

The key thing here is to use :joins to access the users table within the

query. This allows one to access the fields in the query without
displaying

the data of that attribute.

Good luck,
