* | | Expand the number of types which can use prepared statementsSean Griffin2015-01-243-6/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This will allow all types which require no additional handling to use prepared statements. Specifically, this will allow for `true`, `false`, `Date`, `Time`, and any custom PG type to use prepared statements. This also revealed another source of nil columns in bind params, and an inconsistency in their use. The specific inconsistency comes from a nested query coming from a through association, where one of the inversed associations is not bi-directional. The stop-gap is to simply construct the column at the site it is being used. This should simply go away on its own once we use `Attribute` to represent them instead, since we already have all of the information we need.
* | | Don't mutate `where_values`Sean Griffin2015-01-241-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | This is to help facilitate future refactorings, as the internal representation is changed. I'm planning on having `where_values` return an array that's computed on call, which means that mutation will have no affect. This is the only remaining place that was mutating (tested by replacing the method with calling `dup`)
* | | Don't rely on relation mutability when building through associationsSean Griffin2015-01-242-19/+25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Specifically, the issue is relying on `where_unscoping` mutating the where values. It does not, however, mutate the bind values, which could cause an error under certain circumstances. This was not exposed by the tests, since the only place which would have been affected is unscoping a boolean, which doesn't go through prepared statements. I had a hard time getting better test coverage to demonstrate the issue. This in turn, caused `merge` to go through proper logic, and try to clear out the binds associated with the unscoped relation, which then exposed a source of `nil` for the columns, as binds weren't expanding `{ "posts.id" => 1 }` to `{ "posts" => { "id" => 1 } }`. This has been fixed. The bulk of `create_binds` needed to be moved to a separate method, since the dot notation should not be expanded recursively. I'm pretty sure this removes a subtle quirk that a ton of code in `Relation::Merger` is working around, and I suspect that code can be greatly simplified. However, unraveling that rats nest is no small task.

* | | | | Move integer range validation to never raise on assignmentSean Griffin2015-01-234-20/+45
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Given that this was originally added to normalize an error that would have otherwise come from the database (inconsistently), it's more natural for us to raise in `type_cast_for_database`, rather than `type_cast_from_user`. This way, things like numericality validators can handle it instead if the user chooses to do so. It also fixes an issue where assigning an out of range value would make it impossible to assign a new value later. This fixes several vague issues, none of which were ever directly reported, so I have no issue number to give.

This can be useful during development mode to quickly find out which fields need to be selected. For performance critical pages, if you are not using all of the fields of a database, an easy performance win is only selecting the fields which you need. By calling this method at the end of a controller action, it's easy to determine which fields need to be selected. While writing this, I also noticed a place for an easy performance win internally which I had been wanting to introduce. You cannot mutate a field which you have not read. Therefore, we can skip the calculation of in place changes if we have never read from the field. This can significantly speed up methods like `#changed?` if any of the fields have an expensive mutable type (like `serialize`) ``` Calculating ------------------------------------- #changed? with serialized column (before) 391.000 i/100ms #changed? with serialized column (after) 1.514k i/100ms ------------------------------------------------- #changed? with serialized column (before) 4.243k (± 3.7%) i/s - 21.505k #changed? with serialized column (after) 16.789k (± 3.2%) i/s - 84.784k ```

* | | | | Fix bind value copying from subqueried relationsSean Griffin2015-01-193-13/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | With the old implementation, the bind values were created, and then we search the attributes for `Relation` objects, and merge them. This completely ignores the order that the actual `where` clause will use. If all non-relation where parameters are before the relations, it will work. However, if we query on both a relation and a value, with the value coming second, it breaks. The order of the hash should not affect the final query (especially since hashes being ordered is an implementation detail)
* | | | | Move `create_binds` over to the `PredicateBuilder`Sean Griffin2015-01-193-34/+31
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I'm looking to introduce a `WhereClause` class to handle most of this logic, and this method will eventually move over to there. However, this intermediate refactoring should make that easier to do.
* | | | | Whether a column exists or not doesn't affect whether we can use bindsSean Griffin2015-01-192-7/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Looking through the blame, this logic used to be when we actually created the bind tuple. My guess is that `nil` couldn't be handled there at that time. It can, now.
* | | | | Don't mutate bind values in `Relation`Sean Griffin2015-01-192-2/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In order to better facilitate refactoring, most places that mutated `bind_values` have already been removed. One last spot snuck through. Since we're no longer mutating the array, it also does not need to be duped in `initialize_copy`.

* | | | Don't calculate in-place changes on attribute assignmentSean Griffin2015-01-182-1/+9
|/ / / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When an attribute is assigned, we determine if it was already marked as changed so we can determine if we need to clear the changes, or mark it as changed. Since this only affects the `attributes_changed_by_setter` hash, in-place changes are irrelevant to this process. Since calculating in-place changes can be expensive, we can just skip it here. I also added a test for the only edge case I could think of that would be affected by this change.
