* Stop assuming strings for grouped calculationsErnie Miller2012-06-241-6/+17
| | | | | | | | | | | | | | | Execute_grouped_calculation is one of those places where ActiveRecord forgets that it has ARel underpinnings, and assumes that the values provided to group_values are strings. This artificially hobbles otherwise functional code. This patch stops assuming that incoming values respond to to_sym, stops using string interpolation for table aliases on objects that support aliasing, and stops unnecessarily joining group_values on the relation. Additionally, it calls to_sql, if available, on objects sent to column_alias_for, in order to get a more reasonable alias string than a non-string's default to_str method.

* Refactor pluck with multiple columnsCarlos Antonio da Silva2012-06-221-26/+13
| | | | | | | | | | | | Ensure it works with mix of symbols and strings, and with a select clause possibly containing more than one column. Also remove support for pluck with an array of columns, in favor of passing the list of attributes: Model.pluck(:a, :b) See comments: https://github.com/rails/rails/pull/6500#issuecomment-6030292

* Bug fixes:Fadzril Muhamad & Joseph Palermo2011-05-121-5/+4
| | | | | | - If doing a count on a relation that has an :include and a :join, it does a distinct even though it should not. - When doing a count on a relation that has an :include, it always falls back to a old style left join when performing the count. Looks like it was broken here: https://github.com/rails/rails/commit/b9599502c9e738a5a1513e75d08f8d40ed408265
