* Change 'a' to 'an' for 'attribute' word [ci skip]Santosh Wadghule2015-01-211-1/+1

* Introduce `ActiveRecord::Base#accessed_fields`Sean Griffin2015-01-207-1/+88
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This method can be used to see all of the fields on a model which have been read. 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 ```

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If set to `if_exists: true`, it generates a statement like: DROP TABLE IF EXISTS posts This syntax is supported in the popular SQL servers, that is (at least) SQLite, PostgreSQL, MySQL, Oracle and MS SQL Sever. Closes #16366.
* | | 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`.

| | | | | | | | | | | | | | | `.` is regexp meta character. It should be escape for `assert_match` correctly.
* | | 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.

| | | | | | While we don't want to change the form input when validations fail, blindly using `_before_type_cast` will cause the input to display the wrong data for any type which does additional work on database values.

* | Stop special casing null binary data in loggingSean Griffin2015-01-103-9/+7
| | | | | | | | | | | | There's very little value in logging "<NULL binary data>" instead of just "nil". I'd like to remove the column from the equation entirely, and this case is preventing us from doing so.
* | Don't attempt to save dirty attributes which are not persistableSean Griffin2015-01-104-1/+28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This sets a precident for how we handle `attribute` calls, which aren't backed by a database column. We should not take this as a conscious decision on how to handle them, and this can change when we make `attribute` public if we have better ideas in the future. As the composed attributes API gets fleshed out, I expect the `persistable_attributes` method to change to `@attributes.select(&:persistable).keys`, or some more performant variant there-of. This can probably go away completely once we fully move dirty checking into the attribute objects once it gets moved up to Active Model. Fixes #18407
