* Introduce `ActiveRecord::Base#accessed_fields`Sean Griffin2015-01-201-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* Time columns should support time zone aware attributesSean Griffin2015-01-151-0/+14
| | | | | | The types that are affected by `time_zone_aware_attributes` (which is on by default) have been made configurable, in case this is a breaking change for existing applications.
* Stop special casing null binary data in loggingSean Griffin2015-01-101-0/+5
| | | | | | 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 Griffin2015-01-101-0/+7
| | | | | | | | | | | | | | | | 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

|/ | | | | | | | | | | - Fixtures with non-string labels such as integers should be accessed using integer label as key. For eg. pirates(1) or pirates(42). - But this results in NotFound error because the label is converted into string before looking up into the fixtures hash. - After this commit, the label is converted into string only if its a symbol. - This issue was fount out while adding a test case for https://github.com/rails/rails/commit/7b910917.

* Add config to halt callback chain on return falseclaudiob2015-01-021-5/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This stems from [a comment](rails#17227 (comment)) by @dhh. In summary: * New Rails 5.0 apps will not accept `return false` as a way to halt callback chains, and will not display a deprecation warning. * Existing apps ported to Rails 5.0 will still accept `return false` as a way to halt callback chains, albeit with a deprecation warning. For this purpose, this commit introduces a Rails configuration option: ```ruby config.active_support.halt_callback_chains_on_return_false ``` For new Rails 5.0 apps, this option will be set to `false` by a new initializer `config/initializers/callback_terminator.rb`: ```ruby Rails.application.config.active_support.halt_callback_chains_on_return_false = false ``` For existing apps ported to Rails 5.0, the initializers above will not exist. Even running `rake rails:update` will not create this initializer. Since the default value of `halt_callback_chains_on_return_false` is set to `true`, these apps will still accept `return true` as a way to halt callback chains, displaying a deprecation warning. Developers will be able to switch to the new behavior (and stop the warning) by manually adding the line above to their `config/application.rb`. A gist with the suggested release notes to add to Rails 5.0 after this commit is available at https://gist.github.com/claudiob/614c59409fb7d11f2931
* Deprecate `false` as the way to halt AR callbacksclaudiob2015-01-021-0/+8
| | | | | | | | | | Before this commit, returning `false` in an ActiveRecord `before_` callback such as `before_create` would halt the callback chain. After this commit, the behavior is deprecated: will still work until the next release of Rails but will also display a deprecation warning. The preferred way to halt a callback chain is to explicitly `throw(:abort)`.

The `update_all` method can be used in that case if callbacks are not required because it will only run single UPDATE for all the records.
