* Optimize none? and one? relation query methods to use LIMIT and COUNT.Eugene Gilburg2015-02-121-0/+76
| | | | | | | | Use SQL COUNT and LIMIT 1 queries for none? and one? methods if no block or limit is given, instead of loading the entire collection to memory. The any? and many? methods already follow this behavior. [Eugene Gilburg & Rafael Mendonça França]

| * Use an `Attribute` object to represent a bind valueSean Griffin2015-01-271-1/+1
| | | | | | | | | | | | | | | | | | | | | | The column is primarily used for type casting, which we're trying to separate from the idea of a column. Since what we really need is the combination of a name, type, and value, let's use the object that we already have to represent that concept, rather than this tuple. No consumers of the bind values have been changed, only the producers (outside of tests which care too much about internals). This is *finally* possible since the bind values are now produced from a reasonable number of lcoations.
| * `WhereClause#predicates` does not need to be publicSean Griffin2015-01-273-13/+8
| | | | | | | | | | | | | | | | | | | | | | The only place it was accessed was in tests. Many of them have another way that they can test their behavior, that doesn't involve reaching into internals as far as they did. `AssociationScopeTest` is testing a situation where the where clause would have one bind param per predicate, so it can just ignore the predicates entirely. The where chain test was primarly duplicating the logic tested on `WhereClause` directly, so I instead just make sure it calls the appropriate method which is fully tested in isolation.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This error only happens when the foreign key is missing. Before this fix the following exception was being raised: NoMethodError: undefined method `val' for #<Arel::Nodes::BindParam:0x007fc64d19c218> Now the message is: ActiveRecord::UnknownAttributeError: unknown attribute 'foreign_key' for Model.

* | | Setting an association replaces records with the same id in memorySean Griffin2014-11-251-0/+64
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The records weren't being replaced since equality in Active Record is defined in terms of `id` only. It is reasonable to expect that the references would be replaced in memory, even if no queries are actually executed. This change did not appear to affect any other parts of the code base. I chose not to execute callbacks since we're not actually modifying the association in a way that will be persisted. Fixes #17730

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Callback order in Active Record objects are important. Users should not define callbacks before the association definition or surprising behaviours like the described at #3798 will happen. This callback order dependency is documented at https://github.com/rails/rails/blob/31bfcdc77ca0d8cec9b5fe513bdc6f05814dd4f1/activerecord/lib/active_record/associations.rb#L1222-1227.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is cased by 03118bc + 9b5d603. The first commit referenced the undefined local variable `column` when it should be using `reflection.type` as the lookup key. The second commit changed `build_arel` to not modify the `bind_values` in- place so we need to combine the arel's `bind_values` with the relation's when building the SQL.
