Works around this issue: github.com/rails/rails/issues/7121
GROUP BY + COUNT drops SELECT statement. This leads to SQL error when the ORDER statement mentions a column defined in the SELECT statement.
We remove the ORDER statement to work around this issue.
# File lib/active_admin/helpers/collection.rb, line 10 def collection_size(collection=collection) size = collection.reorder("").count # when GROUP BY is used, AR returns Hash instead of Fixnum for .size size = size.size if size.kind_of?(Hash) size end
