* class Foo < Struct.new(:x) creates an extra unneeded anonymous classAkira Matsuda2017-01-131-1/+1

* Properly include the `from` clause when merging relationsSean Griffin2016-01-141-0/+7
| | | | | | | | | | The code that set the from clause was removed in bdc5141652770fd227455681cde1f9899f55b0b9. I did not give any reason for doing so. My assumption was that I intended to change it to use the clause objects, but forgot. We appeared to not have test coverage for this case. Fixes #22996
* Improve error message for #or when it is structurally incompatibleRafael Mendonça França2016-01-131-1/+3

* Revert "Change `WhereClause#merge` to same named columns on diff tables"Sean Griffin2016-01-121-15/+2
| | | | | | | | | This reverts commit 5d41cb3bfd6b19833261622ce5d339b1e580bd8b. This implementation does not properly handle cases involving predicates which are not associated with a bind param. I have the fix in mind, but don't have time to implement just yet. It will be more similar to #22823 than not.
* Change `WhereClause#merge` to same named columns on diff tablesSean Griffin2016-01-121-2/+15
| | | | | | | | | | | | | | | | | | | | While the predicates are an arel equality node where the left side is a full arel attribute, the binds just have the name of the column and nothing else. This means that while splitting the predicates can include the table as a factor, the binds cannot. It's entirely possible that we might be able to have the bind params carry a bit more information (I don't believe the name is used for anything but logging), and that is probably a worthwhile change to make in the future. However the simplest (and likely slightly faster) solution is to simply use the indices of the conflicts in both cases. This means that we only have to compute the collision space once, instead of twice even though we're doing an additional array iteration. Regardless, this method isn't a performance hotspot. Close #22823. [Ben Woosley & Sean Griffin]
* Ensure `Relation` responds to `shuffle`Sean Griffin2015-12-011-1/+1
| | | | | It appears that I missed this one when I delegated all the non-mutation array methods that were not on Enumerable
* Remove blanket array delegation from `Relation`Sean Griffin2015-11-231-6/+0
| | | | | | | | | As was pointed out by #17128, our blacklist of mutation methods was non-exhaustive (and would need to be kept up to date with each new version of Ruby). Now that `Relation` includes `Enumerable`, the number of methods that we actually need to delegate are pretty small. As such, we can change to explicitly delegating the few non-mutation related methods that `Array` has which aren't on `Enumerable`

* deprecate `Relation#uniq` use `Relation#distinct` instead.Yves Senn2015-05-261-4/+13
| | | | | | | | | See #9683 for the reasons we switched to `distinct`. Here is the discussion that triggered the actual deprecation #20198. `uniq`, `uniq!` and `uniq_value` are still around. They will be removed in the next minor release after Rails 5.
* Add `config.active_record.warn_on_records_fetched_greater_than` optionJason Nochlin2015-03-251-0/+28
| | | | | | | | | When set to an integer, a warning will be logged whenever a result set larger than the specified size is returned by a query. Fixes #16463 The warning is outputed a module which is prepended in an initializer, so there will be no performance impact if `config.active_record.warn_on_records_fetched_greater_than` is not set.
* Respect custom primary keys for associations in `Relation#where`Sean Griffin2015-02-041-1/+37
| | | | | | | | | | While we query the proper columns, we go through normal handling for converting the value to a primitive which assumes it should use the table's primary key. If the association specifies a different value (and we know that we're working with an association), we should use the custom primary key instead. Fixes #18813.

* Remove Relation#bind_paramsSean Griffin2015-01-271-2/+2
| | | | | | | | `bound_attributes` is now used universally across the board, removing the need for the conversion layer. These changes are mostly mechanical, with the exception of the log subscriber. Additional, we had to implement `hash` on the attribute objects, so they could be used as a key for query caching.
* Use an `Attribute` object to represent a bind valueSean Griffin2015-01-272-19/+8
| | | | | | | | | | | 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 Griffin2015-01-272-102/+27
| | | | | | | | | | | 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.
* Move where grouping into `WhereClause`Sean Griffin2015-01-271-0/+33

* Move the `from` bind logic to a `FromClause` classSean Griffin2015-01-261-3/+3
| | | | | | | Contrary to my previous commit message, it wasn't overkill, and led to much cleaner code. [Sean Griffin & anthonynavarre]
* Remove `Relation#bind_values=`Sean Griffin2015-01-261-1/+1
| | | | | | | | | | The last place that was assigning it was when `from` is called with a relation to use as a subquery. The implementation was actually completely broken, and would break if you called `from` more than once, or if you called it on a relation, which also had its own join clause, as the bind values would get completely scrambled. The simplest solution was to just move it into its own array, since creating a `FromClause` class for this would be overkill.
