* Deprecate the `:distinct` option for `Relation#count`.Yves Senn2013-03-151-4/+14
| | | | | | | We moved more and more away from passing options to finder / calculation methods. The `:distinct` option in `#count` was one of the remaining places. Since we can now combine `Relation#distinct` with `Relation#count` the option is no longer necessary and can be deprecated.
* rename `Relation#uniq` to `Relation#distinct`. `#uniq` still works.Yves Senn2013-03-151-1/+2
| | | | | | | | The similarity of `Relation#uniq` to `Array#uniq` is confusing. Since our Relation API is close to SQL terms I renamed `#uniq` to `#distinct`. There is no deprecation. `#uniq` and `#uniq!` are aliases and will continue to work. I also updated the documentation to promote the use of `#distinct`.
* `#count` in conjunction with `#uniq` performs distinct count.Yves Senn2013-01-261-0/+4

* Deprecate Relation#sum with a block.Carlos Antonio da Silva2012-11-211-2/+4
| | | | | | | To perform a sum calculation over the array of elements, use to_a.sum(&block). Please check the discussion in f9cb645dfcb5cc89f59d2f8b58a019486c828c73 for more context.

* Remove ActiveRecord::Base.to_aJon Leighton2012-08-031-1/+1
| | | | | On reflection, it seems like a bit of a weird method to have on ActiveRecord::Base, and it shouldn't be needed most of the time anyway.
* Deprecate ActiveRecord::Base.scoped.Jon Leighton2012-07-271-13/+13
| | | | | | | It doesn't serve much purpose now that ActiveRecord::Base.all returns a Relation. The code is moved to active_record_deprecated_finders.
* ActiveRecord::Base.all returns a Relation.Jon Leighton2012-07-271-1/+1
| | | | | | | | | | | Previously it returned an Array. If you want an array, call e.g. `Post.to_a` rather than `Post.all`. This is more explicit. In most cases this should not break existing code, since Relations use method_missing to delegate unknown methods to #to_a anyway.

* Ensure Arel columns are typecasted properly when grouping with calculationCarlos Antonio da Silva2012-06-251-3/+7
| | | | Fix build issue with postgresql.
* Stop assuming strings for grouped calculationsErnie Miller2012-06-241-0/+5
| | | | | | | | | | | | | | | 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 Silva2012-06-221-10/+16
| | | | | | | | | | | | 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

| | | | RUNNING_UNIT_TESTS file for details, but essentially you can now configure things in test/config.yml. You can also run tests directly via the command line, e.g. ruby path/to/test.rb (no rake needed, uses default db connection from test/config.yml). This will help us fix the CI by enabling us to isolate the different Rails versions to different databases.
* Bug fixes:Fadzril Muhamad & Joseph Palermo2011-05-121-0/+11
| | | | | | - 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
